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 Key Warning (USA/Can)
Remote key warning alerts the driver, by means of a text message and an audible acknowledgment signal, not to leave the remote key in the vehicle.
The central electronic module (CEM) receives an indication from a contact breaker in the lock unit that the driver's door is open. The contact breaker is directly connected to the central electronic module (CEM). If a remote key is in the starter module when the driver's door is opened and the engine is switched of the central electronic module (CEM) transmits a message via the controller area network (CAN) to the driver information module (DIM). The driver information module (DIM) then activates an audible acknowledgment signal and shows a warning message in the text display.
