When both stop working in the same time, you should not look at the fobs, but to the receiver or the logic in the alarm system in the first place. Like if two key don't fit in the lock, anymore, the keys did not change, but the lock.
But perhaps you should ask a tech to solve this problem. To diagnose this one is a bit difficult not being on the car myself.
Hi..I'm gonna assume your alarm is aftermarket...Ie...car, pursuit etc. If that's the case make sure your key is off put the remote in your hand, put on your batt cable then hit your remote it should work. If not you should have a little.disarm pushbutton inside the car. Its usually hidden on the kik panal or under dash. Hook up batt.turn on ign hit button if eiether of those don't work find out what kind of alarm and get back with me.
After market alarms are horrible on MB's as they have built in alarms. If you mean the remote your going to have to get the frequency code from the manufacturer or have the dealership program it to control the alarm if the last 1 did.
If you dont know how the system works I would suggest removing it as most systems dont work well with the pneumatic central locking and fail by burning up wiring it is connected to.
