My key broke off inside the back door deadbolt lock, it is the door that leads from the garage and I use even more frequently than the front door, so I called with that emergency and Liam Philadelphia Lock & Key came quickly. He was very professional and quickly removed the broken key piece without damaging the lock it self, he even made me 2 new key copies on the spot and charged a very fair and reasonable price, I’ll definitely call him right away if something like that happens again.
