R350 Alarm
Hi everyone,
The alarm on my R350 (2011) has been going off every night the past week at 4am and the neighbours are getting annoyed. What has made things worse is that now none of my 3 key fobs (changed batteries) unlock the car from a distance and I have to run out to disable the alarm.
Any help/advice greatly appreciated.
Many thanks,
Matt

Only advice I can give is to disconnect the battery for a few hours.
This is the same as rebooting your computer if the analogy applies.
Give it a try and let us know how it goes.
