Residential Locksmith Services - MD & DC
Lock changes, rekeying, smart lock installation, and security upgrades for homeowners and renters across the DMV.
The Locksmith Maryland and DC Homeowners Call First
Mike David has been showing up for Maryland and DC homeowners since 2012 - for lock changes, rekeying, smart lock installation, high security upgrades, and everything in between. Every job comes with upfront pricing before work begins, a guarantee on labor and materials, and the kind of honest assessment you would expect from someone who actually cares whether your home is secure.
When you call us, you are not getting a franchise or a call center. You are getting Mike, an authorized dealer for Medeco, Mul-T-Lock, and Schlage Primus who brings high security expertise that most local locksmiths simply cannot offer. Whether you just moved in, experienced a break-in, or want to upgrade your locks, we will tell you exactly what you need - nothing more, nothing less.
Rekeying is almost always less expensive than replacing locks and is the right first step after any move or key loss. If your hardware is worn or you want to step up to a restricted keyway system that controls key duplication, we will walk you through the options and let you decide. No upselling, no pressure, no bait-and-switch pricing once we are at your door. If you are shopping for a senior family member, our aging in place locksmith services are designed specifically for that conversation.

Mike was able to fix my lock the same day I called. He was efficient and able to remove a broken key from the lock. Awesome service!
— Drew L.
Mike showed up during the allotted time slot. He was kind and efficient. His cost was fair and of good value. I would highly recommend Mike for your locksmith needs.
— Marcia W.
Mike was able to quickly come out and replace my broken office lock. He made extra keys we'd had trouble duplicating in not one but three hardware stores. No problem for Mike!

Your Questions, Answered by Mike
FAQs
-
Rekeying your existing locks is almost always the most affordable option when the hardware is still in good condition. It changes the internal pins so old keys no longer work without replacing the entire lockset. If your locks are worn, damaged, or you want to upgrade your security at the same time, replacing them with quality hardware is worth the additional investment. Mike will walk you through both options and recommend what actually makes sense for your situation.
-
Some locksmiths charge a separate dispatch or call out fee on top of the service cost and do not disclose it until they are at your door. At Mike's Locksmith, pricing is transparent before work begins. You will know the full cost upfront with no fees added after the fact.
-
A trained locksmith can open nearly all standard residential locks non-destructively. High security locks like Medeco and Mul-T-Lock are engineered to be extremely difficult to pick or bypass, which is exactly their purpose. In rare cases involving severely damaged hardware, drilling may be necessary, but that is always discussed with you before any destructive method is used and is genuinely a last resort.
-
Technically yes, but improper installation is one of the most common reasons locks fail to provide real security. A misaligned strike plate, incorrect backset, or loose hardware can make even a quality lock easy to defeat. Having a licensed locksmith install your locks ensures the hardware is fitted correctly, the door and frame are assessed for vulnerabilities, and the job is backed by a guarantee.
-
Rekeying is less expensive in most cases because you are only modifying the existing lock cylinder rather than replacing the entire lockset. The right answer depends on the condition of your current hardware and your security goals. If you have just moved into a new home, rekeying is typically the first step. If your locks are old or you want to upgrade to high security hardware, replacement makes more sense. Mike will give you an honest assessment and let you decide.
-
Payment is collected at the time of service. Mike accepts cash, credit card, and check. For commercial and property management clients, billing arrangements can be discussed in advance. You will always know the total before work begins so there are no surprises when the job is done.
