These folks are the best Locksmiths in Philly. I've tried others that are either closed when I get there or don't know what they are doing. These people are Professional and live up to the Houdini name. I think they can open anything. I've had keys cut all over town and they work perfect only when cut at Houdini. I find them conveniently located at Broad & South Street and very Professional. I've had service from these guys at work and at home and I highly recommend them hands down.
Pros: Fast Service, Open Saturdays, Fair Prices, 24 Hour Emergency Help, Big Inventory, Knowlegable Staff, Nice People
Cons: Retail is closed Sunday, They only have 3 stores and could use more locations
