A1 Security
Our goal is to provide information on the best products available to meet your security needs. In addition, we want you to know what a "security system" is and we can help you develop a plan to obtain one. You should first consider how you will exit in a safe manner in case of fire or emergency. More people die in fires than in burglaries.

We will look closely at your perimeter and interior security needs, whether in the form of hardware or electronics. Commercially we sell and service hardware including electronic keypad entry, card entry, telephone entry systems, intercom systems with an electronic lock release (buzzer system), closed circuit television systems, and door openers for the handicapped.

Our service technicians are highly trained and keep abreast of the latest security technologies to provide our customers with the best services possible. 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

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 can't say enough about the service received from Sure-Fit. So quick to help us out in a time of need. Great customer service from the time of the initial call! 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.

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.

Professional work. What Strosniders seems incapable of doing even after repeated attempts, this shop did the first time. If you need copies made, go straight here.

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.

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!

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

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 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!

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!
