Customer Testimonials

I accidentally left a set of keys in a checked bag for a flight....yep....airline lost my bag. After staying at a friends house that night my wife and I contacted Under Lock and Key and Roger came out immediately to get us back in the house. He is extremely professional and kind and did great work. There are certain people that you know are quality. Roger is one of these people. I would trust him to do the job right every time.

Mr. Berkner was very nice. He came out the next morning after I called in the late afternoon the day before. He was very punctual & made my keys very quickly. I definitely would call him again if I need a locksmith.

My Anderson door's dead bolt jammed in locked position and I couldn't get it open. I tried customer service at Anderson with no avail. I found Roger Angie's list and he was out within an hour. He repaired and lubricated both my outdoor deadbolts and also recommended and performed a re-keying so both doors would use one key. Roger was prompt, polite, professional and the pricing was fair.
