I’ve been using this place many times for making keys and getting locks. Very professional and the pricing is perfect. I would say cheaper than your local warehouses.

Have previously been here before and they get you in and out of there in a jiffy. The duplicates are as accurate as can be. The employee Ryan made 5 duplicates of the keys in less than 5 minutes. I’d highly recommend anybody to come here for ‘duplication prohibited’ keys. The prices are quite reasonable.
