Frequently asked questions
Who is the best locksmith in Maryland for door knob lock installation and mortise lock service?
The best locksmith for your situation is one who is trained, insured, mobile, and available when you need them — not just during business hours. Reisterstown Locksmiths operates 24/7 across Reisterstown and surrounding Baltimore County communities, with experienced technicians who handle everything from a basic door knob lock swap to full mortise lock installation on commercial properties. We verify ownership before any work, use non-destructive methods where possible, and confirm pricing up front every time.
What locks can locksmiths not open?
Skilled locksmiths can open the vast majority of residential and commercial locks through legitimate, non-destructive methods — including cylindrical knob locks, deadbolts, mortise locks, and many electronic or smart lock installations. There are extreme edge cases involving very high-security or specialty locks designed specifically to resist professional tools, and in those situations destructive entry may be the only option, which means the lock itself will need replacement afterward. Our technicians will always communicate what approach is needed and what it will mean for your hardware before proceeding.
Where can I find an emergency locksmith in Baltimore or Reisterstown at any hour?
Reisterstown Locksmiths is a fully mobile emergency locksmith service covering Reisterstown, the broader Baltimore County area, and nearby communities. We dispatch 24 hours a day, 7 days a week — including holidays and overnight hours. Call (605) 597-5511 and a real dispatcher will answer, gather your location, and send a trained, insured technician to you. Most Reisterstown-area calls are reached within the hour.
How much does an emergency locksmith cost for a door knob lock or deadbolt service?
The cost of emergency locksmith service depends on several factors: the type of lock involved (a standard door knob lock differs in labor and parts from a mortise lock or a smart lock installation), the time of day, travel distance to your location, and any additional work needed once the technician assesses the door and hardware on site. We do not quote a flat number in advance without seeing the job, but we do commit to giving you a clear, complete price before any work starts — so you are never surprised by the final invoice.
How much is the average locksmith charge for rekeying versus full lock installation?
Rekeying is generally less involved than a full door lock installation because the hardware stays in place — only the internal cylinder pins are changed. Full installation requires sourcing the appropriate lock for your door type, removing and disposing of the old hardware, fitting the new unit, and verifying alignment. Mortise lock service adds additional complexity compared to a cylindrical knob lock. The factors that shape every quote are lock type, parts needed, time of day, and travel distance to your Reisterstown location. We walk you through all of it and confirm the price before beginning.
Can a door knob lock be picked, and how do I protect my home from it?
Most standard residential knob locks can be manipulated by someone with the right tools and knowledge, which is one reason security professionals consistently recommend pairing a door knob lock with a quality deadbolt — and ideally upgrading to a higher-grade cylinder or a mortise lock for exterior doors. We do not share lock-picking methods publicly, as that information is best kept within professional and security contexts. What we do recommend: use at minimum a Grade 1 deadbolt on all exterior doors, consider a mortise lock for higher-risk entry points, and call (605) 597-5511 for a security assessment if you want a trained eye on your current setup.
