After a couple of months of having trouble with my key card for Renault Megan not being detected, the key finely stopped working altogether. I read through some posts on the forum and came across The Master Lock Smith. I phoned the number and a friendly chap called George talked me through their simple online form. The charge was a very reasonable £22.00. I posted my card key to London from North Wales on Tuesday 2pm registered mail, next day delivery at £6.50. My card key was repaired and posted back to me which I receive on Thursday. Not even 2 days. I was more than impressed with the service I received and would highly recommend this company to anyone finding themselves in the same position.
