Rechargeable battery or regular battery of the remote key

Depending on the vehicle equipment, an integrated rechargeable battery or an integrated regular battery provides the voltage supply of the remote key. A regular battery is fitted if the vehicle has Comfort Access (CA). In all other cases, a rechargeable battery is fitted.

The regular battery cannot be charged. The battery must be replaced if there is no longer any voltage supply for the remote key. The rechargeable battery cannot be replaced individually and is charged when the remote key is locked into position in the ignition lock. A 125 kHz interface within the ignition lock executes the recharging. The rechargeable battery voltage is monitored independently by the remote key and is transmitted to the central gateway module via the data bus K-CAN PERIPHERY.
