Car unlocking itself in the wet/rain?
Thats pretty worrying.
You sure you didn't accidentally pressed the key button?
Don't want to question your post, just want to really make sure that somethings ain't right!
Ill put put it down to a one off... but I know water affects them as if I have the key on me when washing the car, the hose on the handles makes the car repeatedly lock and unlock.

The good news is, the doors won't unlock unless the key is in the near vicinity of the car. So no worries about rain making it unlock while you are away from the vehicle.




There is nothing unusual about it. You have to be within a few feet though.
All keyless go MB's have done that for the last 15 years or so...

The key fob will blink twice with the last red blink on longer.
To reactivate, press any button on the key fob.
I did this on my spare key to save the battery and do it before washing the car.
