Amazing work. New key fob on car and working like normal. He explained what he was going to do and also explained once everything was all complete. Highly recommend to anyone looking to have key fob re-coded due to damage, and at a great price too

Highly recommend this auto locksmith in Penllergaer. I had managed to lock my car key inside my car and couldn’t gain entry. This company sent a quote over to me extremely quickly and allowed me entry to my vehicle the same day. Very professional service and a reasonable price too.
