KEY LOST MEMORY AFTER DISCONNECTING BATTERY
SOURCE: Automatic door locks will not work.
you need to take it to the dealer and have them check the bcm for codes.... also have them check to be sure you have the latest software in the bcm.. its possible that you just need a software update... there are several TSB's covering the concern you have..... it can be a very simple fix with software or even a stuck lock switch may need to be replaced... without the proper diagnostic codes being read from the bcm all that can be done is guessing..and that can be expensive...
SOURCE: Key fob will not reset after replacing battery
replace the key fob, please contact mercedes, who will supply u with a pre programmed key, it will save u a lot of aggro in the long run
SOURCE: I locked my doors on
there is a reset switch to the alarm if it is a factory alarm ask dealer if not you will have to trace it yourself good luck
SOURCE: the alarm will not cut off.
