How to open the trunk using the Starline A93 key fob by pressing a button

Not all car owners know how to open the trunk using the Starline a93 key fob, even despite the obvious convenience of this option. Usually installers activate it during alarm installation, but some, alas, don’t bother. Or they forget to report it.

To check if you can open the trunk using the Starline a93 alarm key fob, do the following:

• On the main key fob, press button 2;

• A short beep will sound;
• Quickly click button 1;

• The key fob will beep three times, the car will blink its headlights three times;
• You managed to open the luggage compartment.

The function works even if the car is armed. In this case, the Starline alarm initiates a temporary shutdown of the shock sensor (so that when the luggage compartment is closed due to an impact, the siren does not blare). At the same time, the open door will blink on the key fob display.

Have you checked?

If Starline a93 refused to open the trunk from the key fob, then this function was not connected to you. The service center may charge a fee for its activation, since the process requires the inclusion of an additional relay in the circuit. If you know anything about wiring, you can try it yourself.

A relay is an auxiliary device that generates a short electrical impulse that triggers an automatic mechanism. In our case, unlocking the luggage compartment.

Is it possible to connect the option on all Starline alarm models?

You can definitely open the trunk using the key fob on the Starline A93 alarm system. The implementation is also feasible on any other model, the main thing is that it has additional channels.

Please note that the car trunk must be equipped with an electric lock (not a mechanical one). If necessary, it is installed additionally.

Connection instructions

Remote trunk opening using the Tomahawk security system remote control (TZ 9010, TW 9020, 9030, 9000, 9031, 9100, 7010, 9011, 5000, 4000, 7100) can be done using a simple scheme. Please note that the trunk is opened by a “minus” impulse from the 18-pin connector of the control unit. A signal (300 mA) lasting one second arrives through the black and yellow wire. It is connected parallel to the wire of the button in the cabin (if equipped). One contact of the key is connected to the ground of the car body.

The wire from the alarm and button is connected to the first contact of the relay. The normally open contact of the “relay” is connected to the positive terminal of the battery. We connect the last contact of the 4-pin relay to the terminal of the electric drive, the “zero” of which goes to ground. Check the operation of the remote door release 5 by pressing the corresponding button on the remote control.

How to enable the “Open trunk from key fob” option

Let's finally look at how to connect the option to unlock the trunk from the alarm key fob. A little effort, and as a result, to open the trunk contactlessly, you only need to press the above combination of buttons on the Starline A93 key fob.

Prepare working tools, a blowtorch, solder, electrical tape, and also buy a power relay with a diode and a platform with wires for them. The diode only allows the set charge current in one direction, so it is important (although the system will work without it, but this is more correct from a safety point of view).

• Carefully remove the trim from the driver's door sill and under the steering column;
• Disconnect the terminals from the battery;

• You need to get to the Starline central alarm unit;
• Unwind the electrical tape from the wiring harness and find the thin black and yellow (brown) tape coming from the 18-pin connector on the system unit. This is the negative output of 1 additional channel Starline a93. This is where the command to open the luggage compartment from the key fob is programmed. If you have a different alarm model, find information in the technical manual about which wires are responsible for additional channels. It is important that the signal on this channel is interval (pulse);
• Positive output – red wire from the engine autostart connector (6-pin);
• Make the connection according to the diagram;

• The triangle highlighted in the diagram is a diode; it is connected between the yellow-black and red wires (between + and -), as well as to the relay. The white mark on the diode means the positive side; accordingly, it should be turned towards the red wiring from the autostart, and the negative - towards the yellow-black wiring from the central alarm module.
• Done, you can connect the battery and test. We described above how to open the trunk using the Starline A93 alarm key fob.

If everything works, all that remains is to insulate the harnesses, hide the central block, and return the cladding to its place.

Problems when opening the trunk and their elimination

In some cases, the compartment does not unlock. If the owner encounters this problem, the following components need to be checked:

• power supply element of the remote control. Due to a low battery charge, the remote control simply does not issue the correct command or transmits a distorted dialogue code. Accordingly, the central unit cannot correctly decrypt it and execute the command. The car battery should be checked in the same way. Perhaps the reason is precisely its weak charge, which has the same consequences. A direct signal that the car did not accept the command is the lack of confirmation in the form of the dimensions blinking three times;
• trunk servo drive. Perhaps the problem is mechanical in nature. Therefore, after pressing the appropriate command, you must listen. A special click in the trunk area will indicate that the servo drive is receiving current, but it is necessary to check the serviceability of the elements (rack, gear and the lock itself), clean and lubricate them to avoid jamming. It is also advisable to diagnose hard traction.
• check the value of the function. This option may not be active for additional channel 1. To do this, you must enter the programming menu. You need to disarm the car, and then press the Valet service button five times to enter the settings mode. After turning on the ignition, the car will blink its headlights five times and sound five times. By pressing the third key, you enter the corresponding menu (AF). By pressing buttons two and three, you need to scroll through the menu to the desired function (13) and set it to parameter 1. The settings will be saved after turning off the ignition.
• firmware Modern firmware does not always interact correctly with the trunk servo drive and power relay. Sometimes downgrading to earlier versions of the firmware can solve the problem;
• safety of wires and correct connection. You need to arm yourself with a tester and a test lamp. With their help, you can check all wires for constant contact. You also need to check the correct location of the diode (plus with a white stripe - to the red wire, minus - to the black-yellow cable);
• microprocessor unit. The central signaling unit is responsible for the correct execution of commands. Due to moisture getting inside, it can short out and fail. Therefore, you can carefully disassemble the module housing and make sure there are no damaged elements. If there is moisture, it is necessary to dry it and lubricate the contacts with alcohol. It is advisable not to use a hairdryer for drying - this can damage the microcontacts and traces of the board;
• controller. If it is installed incorrectly (higher than necessary), the trunk door still opens, but not enough for the limit switch to operate and give the corresponding command to the system. You should try to lift the compartment cover by hand. If the alarm does not go off, it means that the command was executed correctly; you only need to carry out mechanical adjustment of the controller.

Frequent problems and solutions

Well, now you know how to open the trunk using the Starline A93 remote control. What problems can happen in the process?

If everything is connected correctly, but you can’t open the trunk using the key fob:

• Check the battery in the remote control and replace if necessary. Also make sure the car battery is charged and working properly;

• Check the trunk servo. Listen for a click when you press a command on the key fob. If there is no sound, no current is supplied to the electric lock. The device needs to be opened, disassembled, cleaned contacts, connectors, and checked the functionality of internal parts (gears).

• The wires supplying the system are damaged, the connection is made incorrectly. Using a multimeter, test the wires for contact. Make sure the diode is positioned correctly;
• Perhaps the central module is to blame. As a rule, in this case the user should have noticed other “bells” (glitches in the alarm system). Remove it, disassemble it and inspect it. If the board is wet, dry its insides. Clean the contact pads and remove dust with a soft brush. Assembly is performed in reverse order;
• The limit switch on the trunk is not positioned correctly (has moved). Its position needs to be adjusted - raised higher or lowered lower.

If you have checked and ruled out everything, but the option still does not work, we recommend contacting a service center. It may be necessary to change the Starline firmware (for normal interaction with the servo drive and relay).

That's all for us. We told you how to open the trunk on the Starline a93 alarm system from the key fob, as well as how to connect this function. Enjoy it for your health!

Enabling the feature

Connecting the trunk opening function in modern cars usually does not cause difficulties. Older versions of cars must be equipped with an electric lock. This is a simple device, but installation will require additional mechanical work.

After correctly installing the Starline A93 system, many users are lost because they cannot open the trunk using the key fob. Despite the fact that everything works from a button from the interior or using a mechanical key.

Designation of key fob buttons The electronic key for the trunk lock will be activated through an additional channel of the A93 system, which must first be activated. To do this, it is enough to follow the algorithm proposed by the manufacturer:

• press button 2 for a long time and button 1 for a short time;
• the car will respond with three light signals, and the key fob with three sound signals;
• when the security is on, only the trunk lock will open;
• when security is turned off, additionally, the shock sensor will turn off, the key fob indicator will display icons for an open trunk and the shock sensor being turned off;
• after closing the trunk in security mode, the shock sensor is activated, the trunk area will be taken under control in 5 seconds, the key fob will beep once.

There are several other methods for connecting the trunk opening function to the system:

• flexible programming, allows switching from a key fob or from a certain sequence of events;
• using Starline R3 control;
• in Latch mode.

Installation instructions for Starline A96

• set of wrenches with socket heads;
• drill with drills;
• soldering kit: blowtorch, rosin, tin, etc.;
• heat shrink tubes, insulating tape.

1. Car alarms are installed exclusively on cars with an electrical circuit of 12 volts. It is advisable to place the main unit in a place protected from vibrations. The most preferable installation location is under the dashboard - this guarantees concealment from prying eyes, as well as a minimum length of connecting wires. The block is fixed using self-tapping screws or double-sided tape to eliminate the possibility of spontaneous movement.
2. A transceiver with a signal diode is mounted on the windshield of the car. The main condition is a distance of at least 5 centimeters from metal parts in order to avoid interference or distortion when receiving signals. The interior temperature sensor is mounted so that it is away from heat sources or direct sunlight for it to work correctly.
3. The engine temperature sensor must be mounted on its body using one of the M6 ​​bolts. It is advisable to attach it closer to the crankcase cover rather than the cylinder head.
4. A siren is also mounted in the engine compartment. The main condition is to avoid moisture, and also place it away from large heat sources to prevent the horn from melting. Also, the siren connection wires should not be accessible from under the car so that an attacker cannot cut them.
5. The shock sensor is located near the center pillar. It is advisable to mount it so that you can access sensitivity settings if it triggers too often.
6. The Valet service button is installed in an accessible but hidden place. The inner sides of pockets for small items, the central tunnel between the seats, the plane under the decorative plugs of the front panel, etc. are suitable.
7. Also, to connect and configure automatic start on cars equipped with a manual transmission, you will need to program the neutral and connect the limit switches to the handbrake. If the car is equipped with an automatic transmission, then the owner must move the lever to the parking position, otherwise autostart will not occur.

• black. The negative terminal that needs to be attached to the car body is ground;
• red. The positive wire, which is recommended to be connected to the battery or ignition switch.

If the car can be started using the Start button, then the connection is made in a slightly different way:

• the red contact is attached to the battery, but through a fuse designed for a current of no more than 30 amperes;
• The blue wire is connected to the brake pedal;
• the yellow-black cable connects to the start button;
• the yellow and green contacts remain unused.

To implement autorun and turbo timer, an additional algorithm is used:

• the red wire connects to the battery;
• yellow cable to the ignition system;
• green – to the ACC output;
• blue is redundant;
• the black and yellow contact is connected to the starter.

Below is an installation map that will allow you to install a car alarm on any car with an automatic or manual transmission, including Haval H9, Nissan Murano Z51, Toyota or KIA Sportage.

The Tomahawk key fob constantly shows an open trunk: what to do

Starline A93 service mode control

According to the instructions, the transition to this position for the Starline A93 system is carried out in several ways:

• by pressing the buttons on the key fob;
• New model models support the cursor-based service option. This is true for remote controls equipped with a liquid crystal display;
• using voice commands via phone. To do this, you must have a GSM module and a SIM card in the system;
• by sending an SMS with the appropriate code;
• by activating the mode on the Starline website. The option will be available after authorization and login to your personal account.

Each method of transition to this state is discussed in detail below.

Fuel pump blocking by alarm

The blocking relay in the Starline A91 system can be installed on the fuel pump power circuit. Accordingly, it may malfunction - the engine may not start at all or start for a few seconds and stall. If such malfunctions occur, it is necessary to check the corresponding relay for proper contact.

How to remove the fuel pump block

You can remove the lock by turning off the lock relay and connecting the wires directly.

It is also advisable for owners of Starline A94 and A96 systems to check the serviceability of the immobilizer bypass, which may be the cause of the malfunction. The likely problem is broken wires or inconsistent wire contact. In this case, you will need to check the cable for the relay contact and the fuel pump using a light bulb (12 Volts). The tester will not help here, because it will not show the presence of a bad contact. Often the problem arises from the fuel module plug, which must provide reliable contact.

How to unlock the alarm?

One of the common types of car protection from thieves is car alarms. This invention has been around for decades and it successfully performs its assigned functions.

Today there is a wide range of car alarms with various additional functions, from different manufacturers, and price categories. But, nevertheless, a car alarm is, first of all, electronics, which is characterized by periodic failures.

Today we will look at the phenomenon of blocking car alarms, pay a little attention to the features of the most famous brands of devices, and also try to give practical advice on how to unlock a car alarm.

Advice

So, let's assume that you are faced with a problem where the alarm does not respond to the remote control and does not unlock the doors. This can be explained by several reasons. For example, the most common cause is a dead battery in the remote control. Quite often the problem can be a dead car battery.

Finally, more serious breakdowns are malfunctions of the alarm control unit.

In any case, such malfunctions should be eliminated immediately, since due to the peculiarities of many alarm models, unlocking the alarm and opening the car doors is a trifle; it is much more difficult to unlock the engine from the alarm, because electronic protection simply will not allow it to start.

What can you advise if there is a problem with the alarm?

Start with something simple - replace the battery in the remote control, or take the second remote control that comes with the kit, try to unlock the alarm with it. If there is no response, make sure that the car battery is charged.

If your car's alarm light is not flashing, this will be the first sign.

In such cases, the door can be opened with a key, and if the security siren turns on, you need to press the emergency alarm button, which is installed in the car and is called Valet.

But what to do when the control unit is faulty? In this case, we advise you to contact an auto electrician who will either adjust the unit or replace it. Now is the time to talk a little about the features of unlocking alarms from the most famous manufacturers.

How to unlock the Starline alarm system?

Alarms of this brand have their own distinctive features for unlocking the alarm, now we will look at them.

After this, turn off the ignition and receive a sound signal to confirm that the security system has been disarmed.

How to unlock Sherkhan alarm system?

It’s worth noting right away that Sherkhan alarms are one of the most capricious, so it’s often with them that problems arise. But now you will learn how to unlock your Sherkhan alarm system. As in the previous case, you need to open the car with the key, after which the siren will sound. In 5 sec.

You need to turn the ignition on and off three times, as a result of which the alarm mode will turn off. After this, you need to turn the ignition on and off a number of times equal to the first digit of the PIN code. After the beep, dial the second digit, turning the ignition on and off, and so on.

After you have correctly entered the code in this way, the engine can be started.

How to unlock the Sheriff alarm?

If you are the owner of a sheriff alarm, then the procedure for unlocking it is as follows. We open the car with the key, after which the siren goes off.

Turn on the ignition and press the Valet button, which is installed in the car's interior. After this, the sound signal will stop. After this, you need to turn the ignition on and off again and press the button.

As a result of these operations, the alarm will go into service mode.

How to unlock the Alligator alarm?

As in all previous cases, you need to open the car with the key. After that, turn the ignition on and off.

Within 15 seconds you need to press the Valet button for 2 seconds. After this, the car alarm will sound 1 beep.

When you continue to turn the ignition on and off, the alarm will send a signal. Therefore, it is recommended to immediately contact the adjuster.

How to unlock the Panther alarm?

To turn off the Panther alarm in an emergency, you need to turn it on and off, then immediately turn on the ignition and hold the Valet emergency button for 10-15 seconds until the sound signal sounds. After these manipulations, the car engine will be unblocked and the car will be able to move around.

Entering and exiting the main menu

To enter the main menu, press the service button five times with the ignition off. Then turn on the ignition. You will be taken to the main menu.

Short press keys 2 and 3 on the key fob to select the programming item you need:

• AF – service and security functions

• CH 01-CH 09 – setting up additional channels (flexible) Starline A93
• SOUN – setting the siren volume

To exit programming, turn off the ignition.

You can find out where the service button is located from your installer.

It can be located under the panel and tied to some standard harness. Often it is hidden in the space next to the fuse box or directly glued to it.

In the latest versions of Starline A39, the service button is built into the antenna module.

The alarm goes off when the trunk is opened

A car alarm may be triggered due to mechanical breakdowns, depreciation of equipment and incorrect actions of car service specialists. However, fixing the problem is simple with a visual inspection and evaluation of the vehicle's electrical circuit.

Reasons why the alarm goes off when opening the trunk, in addition to the heavy weight of the trunk door:

• excessive installation location of the sensor, which leads to inaccurate operation;
• security mode is turned off;
• The limit switches of the hood and luggage compartment are connected by one power line, which is why they are activated synchronously.

To break the electrical circuit, it is necessary to install diode elements. It may also be necessary to separate the microprocessor unit if the diodes burn out.

Trunk won't open

One of the reasons may also be weather conditions that affect the performance of the sensor. As a result, it cannot correctly transmit the signal from the remote control to the luggage compartment.

Standard methods for solving problems:

1. Carry out diagnostics of the signaling servo drive. There should be a clicking sound when the trunk opens. If you can't hear it, then the drive is damaged. In the event of a malfunction, it is necessary to replace the screw clamp that secures the rod to the trunk opener.
2. Check the wiring for noise. If there are damaged elements, the fuse must be replaced. To perform such operations, you need to contact an electrician at a car service center.

If the settings are lost, you need to:

1. Turn off security mode.
2. Press the Valet button five times and turn on the ignition. An icon with the word AF will appear on the communicator screen.
3. After a long press on the third button and the corresponding sound, the setup mode will turn on. Press key 3 again for a few seconds.
4. Using the second or third button, select item number 13 to configure the channel.
5. Set the value 1 opposite the number 13 by briefly pressing the one key.
6. Turn off the ignition.
