I just had Mercedes repair the shifter mechanism and all of a sudden the locking system no loger works. Is this a coincidence, if not how do I replace the pump?

Do you

Make sure the LED on the remote is working. Change the battery in the remote. Make sure the central locking fuses and relays are in operating condition. Our reference doesn't show the locations of these.

There is no pump. It's electrical. Body control module, relays, wiring, switches, and solenoids at the doors.
