that system is part of D.A.S. 2( driver authorization system verson 2). the lights in the mirror will blink red when lock and green when unlock. during the self diagnoses portion they will blink simutanilusly when the remote key batteries are low and alternating when there is a malfunction with the key or other part of the driver authorization. it sounds like your remote key central locking batteries are low.

Reset your Mercedes-Benz key by placing the key in the ignition of your vehicle while the vehicle is turned off. Do not turn on the vehicle. Press a finger on the "lock" button of your key fob while the key is in the Mercedes' ignition.
Pull the key out of the ignition while continuing to hold the "lock" button down. Continue to hold the "lock" button for the duration of the key resetting process
Use another finger to push down on the "unlock" button five consecutive times. Keep holding down the "lock" button.
Release the "lock" button. This is the end of the resetting process for your Mercedes-Benz. Use your key fob to ensure it is properly working
