Remote Keyless Entry (RKE)

Remote Keyless Entry (RKE) is installed on top of the headlining directly above the rear seat.

The receiver receives the signal, which comes from the remote key and forwards it to the Keyless vehicle module (KVM).

The remote keyless entry (RKE) receiver has a logic which enables it to check that a correct message is received. All communication is decrypted in the keyless vehicle module (KVM). The receiver's signal cable is directly connected to the keyless vehicle module (KVM).

The remote keyless entry (RKE) receiver has three different modes: 

• normal mode
• passive mode.
• TPMS mode.

In normal mode, the receiver waits for a signal from the remote key when a button is pressed.

If the keyless vehicle module (KVM) receives an indication if someone is trying to open, lock, or start the vehicle using keyless entry, the keyless vehicle module (KVM) transmits a signal to the receiver to switch to passive mode for a short period of time. After this time, the receiver reverts to normal mode. The difference between these three modes is the way in which the receiver communicates with the remote key.

When a remote key has been approved and has been used to start the vehicle, Central electronic module (CEM) ignores all messages that come from Remote Keyless Entry (RKE) as long as the engine is running.

The remote keyless entry (RKE) receiver is 30-supply powered via the central electronic module (CEM) and grounded in the body.
