What Our Lock Installation & Rekey Service Includes
Smart Lock Installation
Smart locks connect to your phone or home network for remote access, temporary codes, and activity logs. Maryland homeowners in neighborhoods like Charles Village and Arbutus increasingly request these for rental properties or aging-in-place setups where adult children monitor entry. We install Wi-Fi and Bluetooth models from Yale and Schlage, configure the app with you, and show you how to add or remove users before we leave.
Keyless Entry
Keyless entry systems replace traditional keys with codes, fobs, or cards. You need this when keys are lost repeatedly, when caregivers or housekeepers need scheduled access, or when you simply want one less thing to carry. We retrofit keyless entry onto existing doors in Lansdowne, our Lock Installation & Rekey in Brooklyn Park, and throughout Baltimore County, matching the strike plate and door prep to the new hardware so it operates smoothly for years.
Keypad Lock
Keypad locks use a numbered code entered on a weather-resistant pad. They are reliable, battery-operated, and work well on side doors and basement entrances where you do not want to fumble for keys in Maryland’s icy winters. We stock keypad models from Schlage and Baldwin, program multiple codes for family members, and show you how to change codes yourself if needed.
Biometric Lock
Biometric locks read fingerprints for entry, eliminating codes that can be forgotten or shared. These suit home offices, gun safes, or primary residences where security and speed matter equally. We install fingerprint-enabled deadbolts and handle sets, register your prints on-site, and test every angle and lighting condition before we consider the job done.
Electronic Lock
Electronic locks encompass hardwired and battery-powered systems with features like auto-lock, tamper alarms, and audit trails. You need these for higher security on home businesses, detached garages, or properties in Pumphrey and Lock Installation & Rekey in Baltimore Highlands where break-ins are a concern. We assess your door’s voltage compatibility, install the power supply if needed, and integrate the lock with your existing alarm system when possible.
Key Duplication
Key duplication creates working copies from your original, including high-security keys that hardware stores cannot replicate. We duplicate Medeco, Mul-T-Lock, and standard residential keys on precision machines calibrated weekly. If your original is worn, we decode the bitting and cut a fresh key to factory specifications rather than tracing a damaged pattern that will stick or fail.

Brands We Service for Lock Installation & Rekey
We have installed and serviced Medeco cylinders in hundreds of Maryland homes, particularly in older neighborhoods like Lochearn where original doors deserve high-security retrofits. Our technicians stock Medeco’s patented key control systems and can rekey an existing Medeco deadbolt without replacing the entire hardware. Yale is another staple in our inventory, from their residential smart locks to commercial-grade electrified mortise sets. We have configured Yale Access apps for homeowners in Frederick and programmed networked Yale systems for small businesses in downtown Baltimore.
Baldwin’s solid brass and bronze hardware requires careful door prep and precise backset measurement, work we have done in historic Charles Village rowhouses and new construction alike. Mul-T-Lock’s interactive pin systems and restricted keyways demand specialized pinning kits and factory authorization, both of which we maintain. Whether you have Baldwin, Mul-T-Lock, Medeco, Yale, or any other make, we can help. Our trucks carry the tools and parts to complete most jobs in one visit.
Signs You Need Lock Installation & Rekey Right Now
- Your key sticks, jams, or requires jiggling to turn. This indicates worn pins, a damaged key, or internal corrosion from Maryland’s humid summers and salt air near the Chesapeake. Forcing the key can snap it inside the cylinder, turning a simple rekey into an emergency extraction.
- You have lost track of who has keys to your home. Previous owners, contractors, dog walkers, and grown children who have moved out may still possess working keys. Rekeying resets access without replacing hardware, a flat-price service we quote on the phone.
- Your lock hardware is more than 15 years old. Locks wear gradually, and older mechanisms lack modern pick resistance and bump-proof features. In Baltimore’s established neighborhoods like Roland Park and Guilford, we regularly replace 1980s-era deadbolts with Grade 1 or Grade 2 hardware that meets current security standards.
- You recently experienced a break-in or attempted break-in. Even if the lock held, the mechanism may be damaged or compromised. We inspect for pry marks, drill attempts, and internal stress fractures, then recommend repair or replacement based on what we find.
- You are moving into a new or newly purchased home. Rekeying should be done before you spend your first night. We prioritize these calls in Maryland, often scheduling same-day service in Baltimore, Frederick, and surrounding communities so you sleep with confidence.
Our Lock Installation & Rekey Process - Step by Step
- 1
Call and speak with a live person. When you dial (844) 314-7347, a Strongbox team member answers, day or night. We ask about your lock type, door material, and what you are trying to solve. Then we quote a flat price before scheduling. The price we quote is the price you pay.
- 2
Background-checked technician arrives with ID. Your technician calls before arrival, arrives in a marked vehicle, and presents identification at your door. They wear a uniform and carry the tools and inventory to complete most jobs without a return trip.
- 3
On-site assessment and confirmation. We verify the lock brand, door condition, and any complications we could not see over the phone. If the scope changes, we discuss it with you and confirm a new flat price before any work begins. No surprises.
- 4
Installation or rekeying with precision tools. For rekeys, we disassemble the cylinder, replace the pin stack to match your new key, and test operation at multiple angles. For installations, we use mortise gauges, door jamb templates, and strike plate locators to ensure clean fits that do not bind or sag.
- 5
Final testing, cleanup, and written guarantee. We test every key, every code, every app connection. We sweep our work area. Then we leave you with the 90-Day Done Right Promise in writing, our direct line, and the confidence that if anything is not right, we come back.
How Much Does Lock Installation & Rekey Cost in Maryland?
A typical residential rekey in Maryland runs $89-$150 for the first cylinder and $15-$35 for each additional, depending on lock complexity and whether high-security pins are required. Standard deadbolt installation ranges from $140-$280 including labor and a Grade 2 lockset. Smart lock installation in Maryland typically costs $200-$450, with the higher end covering hardwired electronic systems or doors needing significant prep work.
Several factors affect your final price. High-security brands like Medeco and Mul-T-Lock require specialized pinning kits and restricted key blanks that cost more than standard hardware. Door condition matters too, a rotted jamb in an older Lansdowne home may need reinforcement before a new lock will hold properly. Electronic and biometric systems add wiring, power supply, and network configuration time. We discuss all of this when you call and quote accordingly.
To avoid overpaying, refuse any locksmith who will not quote a firm price before dispatch. The $19 service call is a well-documented bait-and-switch tactic in Maryland. Ask whether the quote includes labor, parts, and trip charge. Ask about guarantees. Strongbox includes all costs in our flat price, and our 90-Day Done Right Promise covers both labor and hardware. Call (844) 314-7347 for a free estimate with no obligation.
