We offer mobile and in-store lock services, and staff 10 professional locksmiths for your convenience. In the state of Maryland, a Professional Locksmith must be licensed.
Locks are such an everyday part of our lives that we sometimes take them for granted, until they fail or are compromised. We want to help you find the hardware that is right for you when that happens. Or if you are ahead of the game and want to upgrade to better hardware, knowing the answers to the following questions can help us get what you need.
The color of the lock is referred to as the finish. An important factor in determining finish is climate. Salty air, corrosive vapors, or constant high humidity may have a damaging effect on metal finishes. How long a finish will hold up will be influenced by the base metal and finishing process as well as the different methods of cleaning and care.

Gave them a five + star since I didn’t use them but (Jim) was extremely helpful in explaining my options and offered great advise. If this is any sign of how they treat customers, I would definitely recommend. Love his honesty and professionalism

Over the years it has been a relief to depend on Sure-Fit. From a challenging situation regarding conforming to condo rules while being forced to use a busted door handle to locks, it seems I need them quickly and they do come immediately with no problem. Every technician that was sent over the years was terrific. Never a need for a second or third trip back! I felt very good about them. In addition, we value their opinions about what is best. Truly great company.

I called to get information about their service and pricing, but their people were rude and argumentative. I was shocked to hear how they speak to a potential customer. Totally unacceptable.

I have used Sure Fit several times to install door locks and replacement locks for my office and my home. They are always on time, professional and courteous. I would recommend them if you need locks replaced or other security work.

Getting stuck in a bathroom due to a broken lock was not how we expected to spend our afternoon. Michael was able to make a house call right away and tried a variety of techniques to open the door. He was very professional and offered to replace the broken lock with a spare. He came prepared and wearing a mask so we felt safe and secure. Thank you so much for coming right away and helping us get out of a stressful situation! Recommend Sure-fit locksmiths for fast, friendly, professional service!

I had a very complicated problem, not worth the time it would take for a locksmith to solve it. I was amazed at the cooperation and effort that Sure-Fit put into my problem.

30 years ago, when our house was built, I had Medeco high-security locks put in, using a high-security keyway so that keys could not be duplicated without my signature. The locks are still working just great, all this time later. But I wanted to order a couple more keys.

I called the locksmith, but they're gone. Turns out that a good bit of subsequent investigation on my part showed that they are actually long gone

Great technician who was here in less than 15 minutes. Professional, courteous and sincere. I recommend them highly! I will definitely use them again. Great local Company in Silver Spring.

Sure-Fit Security shows why small, locally owned companies are so much more valuable to a community than large impersonal chains. After returning from the hospital late at night, the lock to my front door broke and I spent a sleepless hot and humid summer night on the porch. I walked to Sure-Fit in the morning and upon seeing my state they gave me an electrolyte drink to help restore me and sent a locksmith to my place quickly so I could get some sleep. Thank you so much Sure-Fit!

Do not trust their inspection of doors. They did an inspection on my landlord's condo door and said it needed replacing for such a small bent on the door. Attached is the picture. Their customer support said a small bent is indicative of the door's "structural compromise". I'd say this is indicative of their scam-like business practices. Don't believe me, then hire a private or state inspector and see what they say. I am sure you would notice a huge difference. In addition, they wanted to charge me $2.5k for replacing the door. 2.5x the market value. I am sure not going to do business with them

Sure-Fit reached out to me and apologized for my the initial poor service after my previous review and experienced. I got a very reasonable quote from them for some locks for a local school. They are very knowledgeable of the many rules governing installing locks on classroom doors. I think my initial experience was an outlier and I do recommend them now.

They came out super promptly to fix a broken front door that wouldn't lock, and they do an excellent job making copies of a key we have that is apparently super hard to make copies of (we tried other places and they kept making crappy copies that didn't work). These guys are good at what they do and they're pleasant. Highly recommended.

After a change in staff we were looking to get new keys cut for various doors and installing new key locks on old doors. They were very accommodating. I was able to send them pictures of all of the issues we had and they gave me price quotes. They also did our Medeco keys. The technician, Michael, came out and he was very pleasant. Overall the best experience I have ever had with a locksmith company from the initial call, to my various questions, to coming out and completing the work. Will recommend them to others.

I lost the key to my bicycle hitch after a long trip from Florida to DC. I ordered replacement keys from the manufacturer, but these would have taken several days to ship and be delivered. In the meantime, I would have had to drive around with a hitch and five bicycles hanging from it.

I looked for alternative solutions and found Sure-Fit Security on Yelp. I read through several excellent reviews and decided to give them a shot. They solved my problem in fewer than five minutes... Literally! Excellent service, excellent attitude, very customer-oriented. I am extremely pleased with the service

Very friendly and inexpensive key-cutting. I highly recommend them. I went in to get my car key cut after buying a cheap replacement shell online. The guy took two seconds and cut my key perfectly. I was able to transfer the button base and chip to the replacement shell, and it works like a charm. In total, I saved over $100 by buying the shell key through Amazon and getting the key cut with Sure-fit, instead of going to the dealership. Thanks!

So helpful! I lost the key to my filing cabinet and called Sure-Fit Security to schedule a locksmith appointment. Instead, over the phone, they walked me through the steps to find a keycode on my cabinet, which they had in stock. So I drove to the shop 10 minutes later and the key was ready to go. They said they couldn't guarantee it would open, but it was only $16 & worked like a charm! Saved me a few hundred dollars in a service visit. :)

I don't think I ever meet anyone as patience as Carl in a customer facing position. I came to Sure-Fit today to pick-up some keys for the dorms at my job. Yes, the college babies are back from summer break. This was a last minute request but Carl handled it like a champ. Even in the mix of some miscommunication and certain keys he admitted might not have been cut right, his customer service never lacked one bit. Carl stepped up, and stepped in to make sure everything will be resolved.

If you ever need any extra security measures or keys made, Carl is the man. The prices are efficient and

Chris D unlocked a bedroom door with a keyed lock in a matter of seconds. I'd called at 8 am, he picked up promptly, and was at my home in maybe 10 minutes. I run an Airbnb and this can happen again with a tenant so I'm keeping this number in my phone sacrosanct! Good price. Less than I expected but in the ball park. Thanks for taking stress off the beginning of my day!

While visiting my sister in Takoma Park, she asked if I could be handyman on several lock issues. I called Sure-Fit, and spoke to "Carl", describing my problem: I had a 1910 lock with a broken spring. Could they repair it? I also had a 1" thick storm door. Did they have a lock to fit it? Carl asked me to send pictures so he could be ready when I arrived. Twenty minutes later I handed Carl the broken lock, purchased his recommended storm door lock (which he rekeyed to match my other outside keys), and had him rekey a 3rd lock I was installing to match the rest. He showed me several

My key broke in the lock of my front door recently. Sure-Fit came out quickly (staying in touch to update me when they would be at my house) and took care of my issue efficiently (explaining what they were doing the entire time). It was a simple fix that, in the unflikely event that it should happen again, I might be able to take care of myself. They entire process and interaction with them was professional and felt quite ethical. I would recommend Sure Fit from my experience.

I inherited restricted Sure-Fit lock systems at both my office and my home, so I've had a number of opportunities to interact with them over the past few years. At first, I definitely balked at the cost for making a single key, especially when I'm the kind of person who always like to have extra keys just in case...

That said, the process you have to go through (just the first time) to open a new account is rigorous - I even had to bring in a copy of my deed of sale for the new house! I'd never really thought about it... but those $3.95 keys you can get cut at any hardware store

I locked myself out of my house. Surefit was there quickly and got me in my house in about 100 seconds. I wished the technician would have struggled for 3 hours so I would feel like my $20 lock was a $300 lock :-)

Very fair weekend price!

Job well done!

When I first walked in to the Sure-fit Security office it was not impressive because it doesn't appear as though you are going to find what you want. But I thought I should focus on their service rather their office infrastructure. And I was right. Their service is trustworthy and above average. The technician arrived on time and performed a very professional appearing installation. He also showed me how it all worked, cleaned up and headed off. Nice service.

The folks at Sure-Fit were complete lifesavers. I'd been searching for weeks (literally) for a place that would make extra copies of our apartment key but because it was an older key it was impossible to track down a place that could make the copy - that is, except for Sure-Fit! They made the key in under 2 minutes and were courteous and professional the entire time. I'll be coming back here for sure!
