How to change the battery in the key?

Most modern car chip-keys have practically the same design. Such keys are becoming more and more complicated and functional. But all of them work from regular batteries. It is clear that the battery’s resource ends with time. When it fails, many car owners don’t even realize at once that it is the battery and try to check alarm and other systems. In fact, it is not at all difficult to understand that the battery needs to be replaced. You can do everything yourself. You only need to know how to change the battery in the key. Especially since in most cars it is done in the same way. If your car has turned into a pile of metal for one reason or another, changing the battery in the key is a pointless exercise. To get money for this junk and buy a new car, write here:

Signs that the battery is dead

The main sign is, of course, that the alarm does not work, and you can not start the car. In this case, you need to use an ordinary mechanical key to open the car. And then it is already necessary to deal with it.

In modern foreign cars it is enough to look at the dashboard. There is an indicator there that shows the presence of pairing of the auto key and the car system. If it is blinking, it means there is no pairing, and it happens only at dead battery.

But in order to check this, you need to open the car. It is not difficult to do if you have a mechanical key. But some brands make cars that do not even have a hole for the key. But there is a hidden emergency key, which allows you not only to open the car, but even to start the engine, so you can get to the service center. As a rule, such systems are implemented for cars of expensive brands (for example, Mercedes). Their chip keys are still too complicated for the car owner to fix the situation himself.

In cheaper car models, it is possible to open the car with an ordinary key. But it is better not to bring the situation to the point when the battery is completely discharged. The fact that it is close to this is indicated by such signs:

Reduced range of the remote control.
Appearance of a warning signal on the dashboard.
The car ignition does not immediately respond to key signals.
So, it is necessary to change the battery, only first you need to read the instructions.

What difficulties may arise when replacing the battery

The main thing that will be required from the owner of the car in such cases, it is promptness. The fact is that if there is no power in the key cell for a long time, the regular code is completely erased. Therefore, the replacement of the battery should take the owner of the car no more than 3-5 minutes. Otherwise, then you will need to re-synchronize the device with the central lock. In addition, after installing the key fob, in place should remain a tag transponder, so act very carefully. If you are not confident that you can cope with this task, it is better to contact the service center.
