Remote Key Lock

Included in the security system is the function for locking the remote key in the Start control module (SCU). This function means that the remote key cannot be removed if the gear selector is not in the park (P) position.(only cars with automatic transmissions).

The vehicle must be stationary and the engine switched off in order for the remote control key to be removed (applies to vehicles both with and without automatic transmission).

This function is checked by the central electronic module (CEM). The Start control module (SCU) contains a contact breaker that closes when the remote key is pressed to the limit position in the Start control module (SCU). The contact breaker indicates to the Start control module (SCU) that the motor for insertion and ejection of the remote key must be activated to draw in or eject the remote key. The Central electronic module (CEM) continually checks if remote key ejection is permitted by checking the signals for:

• engine status from the Engine control module (ECM)
• gear selector position from the Transmission control module (TCM)
• vehicle speed from the Brake control module (BCM).

A message is transmitted at regular intervals to the Start control module (SCU) about whether the remote key can be removed or not. If the remote key is inserted and ejection is permitted according to the Central electronic module (CEM), the Start control module (SCU) activates the motor for insertion and ejection. If the gear selector is not in position P, a message is displayed in the Driver information module (DIM), with a request to shift the gear selector to the P position. The remote key will not be ejected.
