Hi guys, can someone please help. I have a C180 2001 model, I'm having a problem with my remote locking and unlocking. The infrared is working, tested that through my camera. Light is flashing bright when I push the lock and unlock buttons and even changed the batteries. If I play around with the remote holding it close to the sensor on the driver side handle then sometimes will lock and unlock. I thought it might be the all activity module but was told only the ML has AAM... Has anyone experienced this problem?
