so I have keyless entry. Today while stood by the locked car it just unlocked itself. Car was wet/mild rain/drizzle. Wondering if the touch sensors on the handles could have been fooled by the conductivity of them being wet.

Thats pretty worrying.

Maaan....wow!
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!

I thought about that and the key was in my jacket pocket. I checked it and nothing else was in the pocket nor was I pressing against it.

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.

Not sure about a drizzle but when washing our cars, they constantly lock/unlock themselves.

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...

Yep...I have to make sure the FOB is not in my pocket when I'm washing the car.

Same here. But I never remember to take the darn fob out of my pocket until the car locks or unlocks the first time.

Have the same problem with my Audi... at the Stealer multiple times for this. Couldn't fix it.

If you double lock the car on the key fob the door sensor are disabled and it won't cycle the door locks when washing for example..

double pressing the key fob lock button quickly turns off the keyfob.
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.

so if I double press the key when I park for the night it will shut off the key fob, preserving battery life, then the keyless open feature won't work in the morning, i.e. I need to open it by pushing the button?

Mikey53

Yes

user 29474838

Thats correct

Ok so I think this is definitely a bigger issue. I've had no stop start for a while, then I get this unlocking thing and now I've just gone out to the car to find the boot wide open (estate). The boot was closed when I took the dogs out for a walk earlier and the car keys have been stored since I got home.

Maybe your cars haunted?

The keyless can have an amazing range at times. I inadvertently went to the wrong car park level the other day and pressed the keyfob to unlock the trunk only to realise the car wasn't there. When I finally walked down one more level to my car I saw it sitting there with the bootlid already wide open. Didn't think it would carry across levels in a concrete underground car park like that, but obviously it did.
