I'd just like to add my praise to Gary at Keyrepair. A couple of months back my key wouldn't lock. I carefully cut it open to find the microswitch had detached. I was quoted £130 by a Renault dealership and £180 by an independant. I almost bought what would have been a useless key on
for about £50.
Luckily I found keyrepair.co.uk and Gary had it back to me fixed within a couple of days. Brilliant !
