Why does not the car open with a keychain?

To date, the alarm is the main means of protecting the car from thieves and intruders. Control the operation of this device can be remotely by using a special small console, which is called a key fob. However, despite its reliability, and this improved protection system can fail. Therefore, when the car does not open with a keychain, many people simply do not know what to do. In this case, simply open the machine with a key, and with the reasons for such a breakdown you can sort out later.

There is no exact answer

No master on the go will not tell you the reason why the car does not open with a keychain. Indeed, in fact, there can be many such reasons. In this article, the most frequent of them will be considered.

Possible problems with the key fob

Most often, the car does not open with a keychain, because of problems with the small remote control itself. It is very likely that the batteries could sit in it. Therefore, replace them first.

Now carefully examine the key chain itself. If this device is equipped with a screen, please note whether it lights up after you click on the corresponding button. If there is no screen, then find the diode, which very often car owners set themselves, signaling a low battery charge.

If you need to open the car urgently, and there are no spare batteries in your pocket, do not be discouraged and try to do a certain procedure. Remove the old batteries from the remote and tap them against each other several times. Now return the batteries to their original location and try to open the car one more time.

It is possible that the car does not open with a keychain, because of the breakdown of the console itself. In this case, the problem lies in the special sensor. This can occur as a result of a very frequent press of the button to open the car (for example, accidental clicks in the pocket). If you have a spare remote control, then use it to open the car.

The car battery is exhausted

So many people wonder: why does not the car open with a keychain? Of course, one can not give an unambiguous answer, but in fact there can be many reasons. No less common problem is a discharged battery. If you are in this situation, then approach as close as possible to your iron friend and click on the button one more time. Very often carrying out such manipulation helps to open the car, but very little chance that you will be able to leave it. After all, the battery is completely discharged.

With such a problem, inexperienced and inattentive drivers often encounter. Do not forget to turn off the light inside your car, after you put it in the garage or parking lot. The left light, even for only a few hours, will lead to a complete discharge of the engine.

Problems with radio interference

If the car does not open from the Starline keyfob, the problem may be hidden in the radio interference. Sometimes the signal from your console may be silenced. This happens very often, especially if you are in a hard-to-reach zone. In this case, the car will open quite hard. For example, radio waves will become much weaker if you are close to such facilities as an airport, military base or other important state installations. In order to check the radio wave interference, pay attention to your mobile phone.

In order to still open your car, bring the console as close to the receiver of the signal and press the button one more time.

Software failure

The reason why the car does not open from the "Sherkhan" key-signaling device can be a software failure between the console itself and the signal receiver. In this case, the only way to eliminate the problem is reprogramming the bundle. In order to do this, use the emergency mode. Pull the wires out of the signaling unit, disconnecting the control. Now you need to synchronize it with the alarm control panel.

In fact, it is not difficult to conduct such an operation, therefore each driver can do it himself.

However, sometimes there are times when you can not cope with the problem yourself. The reason for this lies in the disappearance of the software from the memory of the equipment itself. In this case, you will have to contact the service center for your device to be requested and reprogrammed.

Something's wrong with the car's electronics

If the machine does not open with the "Tomahawk" keyfob, then in this case the problem may be the faulty wiring of the car or in other electronics malfunctions.

For example, there may be a significant voltage jump in the alarm management system itself, which will lead it out of the operating system. Or, on the contrary, the fault of the control unit itself will lead to common problems with the wiring of your machine. The most frequent sign of a malfunction in the signaling is its self-switching off and on. Also, the system begins to react poorly to the commands being submitted, and eventually it completely fails.

If you have even the slightest suspicion of a possible breakdown, do not delay the time, immediately go to the service center.

What to do if the alarm stops responding to the key chain

If the car does not open with a keychain alarm (the reasons for this phenomenon are described in this article), then in this case, you can perform two specific actions for disabling:

1. Use the emergency stop function. Do not forget that each alarm system has its own code, which the driver should remember even during its installation. To enter it, find the Valet button in your machine. It is responsible for the operation of the system itself and performs many functions. Usually this button can be found in the car interior (for example, under the steering wheel or near the fuse box). Only after you find this button, you can enter the secret code.
2. Another way to turn off the alarm is to bring the key fob as close as possible to the control unit itself and very often press the remote control button on the remote control. Most often, such fraud is enough to disable the car alarm. Almost always it helps to convey a wave that is perfectly acceptable for shutdown.

The alarm system lives its own life

Alarm Starline (opens the car with a keychain), just like other devices, quite often fails. Probably, every driver encountered a problem when the alarm system operated without the owner's commands. Specialists recommend paying attention to three causes of this problem.

Contact Problems

If you use the car very sloppy, and even in an environment with high humidity, then the process of oxidation of the contact buttons, from which the signaling and receives signals, may begin. In this case, experts recommend to replace the end.

Breakage of doors

Sometimes there are situations (especially for second-hand cars), when the informer on the keychain shows that the car doors are open, but in reality everything is not so. In this case, you need to pay attention to the condition of the doors themselves. Check whether the central lock is in working condition, as well as all fuses and wiring of the vehicle. This problem usually occurs in regions with a too cold climate. This is due to the fact that the machinery of the machine just freezes.

Sensors are not working properly.

For today in modern cars the huge quantity of gauges is established. So, the alarm system is perfectly guided by their indications. For example, if the shock sensor is particularly sensitive, then the alarm will operate by itself even from the usual wind or quickly passing by the car. In this case, you need to properly adjust all the sensors, and such situations will not occur.

Experts recommend that if you have any problems with the alarm system, contact the service center, because the car is not the cheapest pleasure, so take care of it and use it correctly. Defining the cause of the failure in advance, you can save your iron friend from burglary.
