Remote control car key:
1 - button for unlocking door locks;
2 - button for blocking door locks.
If the clarity and range of the key decreases, the battery must be replaced.
To do this, use a thin slotted screwdriver to lift the latch and remove the remote unlocking device from the key housing.
Overcoming the resistance of the latches, remove the back cover.
We take out the battery.
Warning! After removing the battery, you have three minutes to install a new one. Otherwise, it will be necessary to synchronize the keys with the control unit.
Install the battery in the reverse order, observing the polarity of the connection.
If the replacement was carried out for more than three minutes, it is necessary to synchronize the key with the central locking device. To do this, insert the key into the ignition switch and turn it to position II (see «Switch (lock) ignition»), Within thirty seconds after the ignition is turned on (without removing the key from the lock) press one of the keys on the key. Synchronization will be confirmed by locking and unlocking the central lock once.
In addition, an electronic chip can be embedded in the key that transmits a specific code to control the immobilizer, if the car is equipped with it.
