Something quite worrying has just happened..

Popped out with the Missus round to her old dears house, parked up, got out, locked the car n went inside. Was in there about half an hour.

On walking back to the car I saw that the footwell lights was on, opened the door to find that it was already unlocked

Told myself maybe I didnt lock it properly when I got out. Pulled off, autolocking locked the doors n drove home

Parked up in my space, then on turning the ignition off, the car automatically unlocked itself, the timing was probably a coincidence but the point is it unlocked itself.

Very concerned sat thinking what could be wrong and thought I'll be putting my wheel lock on tonight, opened the door n on climbing out, the doors unlocked themselves again (while already open)

Can anyone advise on this asap?

Thinking maybe its nothing n the key fob in my pocket could of been in a funny position n accidentally pressed itself, but to do it 3 times (that I know of) in a period of time is obviously highly worrying

Could it be the battery in the fob on the way out?

Or could it be something more serious and underlying

check the fuses in the rear box mate, it could be one of the door fuses has gone. I removed the rear offside fuse and put it back in the wrong slot, tried to lock the car and had the same issue.
