This is an odd one, and I cant find any help on the internet!
Basically, my car key cuts out sometimes, as in if I try to unlock the car from, say, the front door, it wont work. It sometimes works if I walk around the car close.
The strange part is that, to make the key work as it should, I open the key up, remove all the bits, and then put it back together - problem solved for another couple of days!
Mad!
