General Information

The Remote Keyless Entry (RKE) system operates by means of remote control to lock and unlock the vehicle doors and to release the liftgate window (E54 only).

The remote control door lock receiver is located on carrier for the instrument panel. The remote control door lock transmitters, which are supplied in pairs with each vehicle, are hand-held and attached to a key ring. The transmitter has three buttons to control the operation of the system. When any of the buttons are pushed, the transmitter sends a coded ultra-high frequency (UHF) radio signal to the receiver.

The transmitter must be within approximately 10 meters (33 feet) of the vehicle in order for the receiver to detect the coded signal. The RKE system has no effect on the normal operation of the power door locks or the liftgate window release.

Each receiver is capable of recognizing only two transmitters. Replacement transmitters may be obtained, but must be matched to the specific receiver. The transmitter is powered by a 3-volt battery and is water resistant.
