Every time I have been in their business they were quick to finish and let me know the entire cost and when it was something they did not have equipment for or knowledge of they gave me good contact to help

The people here are so helpful, kind and extremely knowledgeable! I needed extra car key and door keys and they knew a lot about the chips in my car key. They also made me at least 10 keys over past few months and they have always been perfect. Different car keys, different door keys always perfect! They are super nice and very helpful!!!! Thanks Mr. 🔐 Lock

Prices are low compared to competitors. Nice family run business for Anderson and Mt. Washington residents.

They were able to get into my Penske rental truck when AAA and the police couldn't! Best service to use when you're in a pinch!

Great find...I live in Milford. So it was a little drive for me. He is able to do all kinds of keys and is very informative. Will be back.

Old school customer service!! What a great experience. I had a spare ignition key made for my motorcycle and it works better than the original. I highly recommend this business.

I scheduled Mr. Lock to update new locks (and make copies) in a newly purchased home. One of their associates came and did a great job! They replaced the locks for three doors in about 1.5 hours. All of this happened during the uncertainty of the COVID-19 "stay at home" order so I'm really grateful for their essential services! They were recommended by my realtor, glad she did!

Mr. Lock came out immediately when a door was broken into on property cared for by a non-profit four years ago. They installed a heavy duty dead bolt with an additional lock and the building has been secure ever since. They have installed all of our dead bolts on the exterior doors of our home. Their prices are very fair and they respond quickly. I'm delighted to have them as a member of our Mt. Washington community.

Needed just one house key, super old school with no special locks. I typically head to Lowe's but Mr. Lock is right up the street from me. I called ahead because I really didn't want to get two kids out of the car if they couldn't help me.

I checked out their website and it seemed like they only did the specialty locks and keys. However, I was pleasantly surprised when the nice man on the phone said, "come on in, we'll get you out of here in no time."

They literally got me out of there in no time. The shop is small but they have every single thing you could ever

Bought a hutch with a locked door. Made several trips for different skeleton keys. Some there suggested to bring in another door from that hutch (good idea). Dropped off the door, a few days later they called. The new key snapped off in the door and is stuck. I took the broken key to Mr Lock Locksmith (the one THEY made). Man behind the counter asks, "So what do you want me to do?" He proceeded to tell me it is $65 plus whatever they do, for them to make a house call. he DID NOT offer a refund, rebate, discounted house call or nothing. As I turn to leave, he asks if I wanted

Fantastic experience today. After an hour long debacle at dealer I was able to get a key made right before they closed. They even walked out to the car with me to make sure it worked. Highly recommend. Will definitely return.

My company recently used Mr. Lock to install an intercom system in our office building, and they did a great job. They gave us the best deal on a simple system that totally fit our needs (rather than another company that wanted to charge us a small fortune for a system that was more complicated than what we needed/wanted, and also they were sort of trying to unload).

The Mr. Lock staff was totally great, too. The owner came to estimate our job himself, and the two guys he sent to do the install were wonderful about working with us on aesthetics (hiding the wire) and very patient with our old,
