Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 two different modes:
- normal mode
- passive 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 from the door handle that someone is trying to open 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 two modes is the way in which the receiver communicates with the remote key.
When a remote key has been approved and used to start the vehicle, the Central electronic module (CEM) ignores all messages from the remote keyless entry (RKE) as long as the engine is running. This prevents the status of the system from changing if a button on another remote key is unintentionally pressed in.
The remote keyless entry (RKE) receiver is 30-supply powered via the central electronic module (CEM) and grounded in the body.
