Randallstown is not a town of quick flips and new construction. The homes here, mostly split-levels and ranchers built between 1955 and 1980, were made to last - but the locks and strike plates that came with them were not. We have rekeyed inherited properties off Liberty Road, reinforced original steel doors in the Cherry Hill area, and upgraded deadbolts in the Lyonswood neighborhood where the same family has owned since 1972. When you call us, you get a background-checked, uniformed technician who shows ID at the door and quotes a real price on the phone. The price we quote is the price you pay.
Why Strongbox Lock & Safe Co. Is Randallstown’s Preferred Lock Installation & Rekey Company
We have built our reputation in Randallstown one job at a time. Our technicians know the local housing stock - the split-levels with swollen summer frames, the ranchers with original Kwikset deadbolts, the colonials with hollow-core side doors that freeze shut in January. That knowledge saves time and gets the job done right.
Our customers in Randallstown leave reviews that mention the same things: we answer the phone with a live person, 24/7; we show up when we say we will; and we back every job with the 90-Day Done Right Promise in writing. No paperwork to file, no arguing if something needs adjustment. We just come back and fix it.
Response time to Randallstown is typically 30-45 minutes from confirmation, since our Baltimore County routes keep us in the area throughout the week. We do not subcontract to unvetted technicians, and we do not quote $19 over the phone only to charge $400 at the door. A square deal: the price we quote is the price you pay.
Our Lock Installation & Rekey Services in Randallstown
Smart Lock Installation
Smart lock installation in Randallstown runs $220-$420, depending on whether your existing deadbolt needs replacement or the door requires reinforcement for the thicker smart lock housing. Many of Randallstown’s 1960s-70s ranchers and split-levels still carry original steel doors with pre-ANSI deadbolts and undersized strike plates screwed into soft door casing instead of stud framing, making reinforced strike upgrades a near-universal need before a smart lock goes on. We have installed Schlage Encode and Yale Assure locks on homes throughout the Lyonswood and Cherry Hill areas, running new strike plates with 3-inch screws into the framing stud so the smart lock has something solid to anchor to. Wi-Fi connectivity works fine here - Randallstown’s residential internet infrastructure supports the remote-access features our customers want.
Keyless Entry & Keypad Lock Installation
Keypad lock installation for Randallstown homes typically costs $180-$340, with commercial-grade units for Liberty Road strip-mall tenants running higher. We regularly install Kwikset SmartCode and Schlage keypad deadbolts on inherited properties where the new owner wants to eliminate rekeying costs from tenant turnover. For the commercial spaces along Liberty Road, we have re-pinned master-key cylinders and installed standalone keypad locks so prior tenants’ keys become useless overnight. The humid Baltimore County summers do not affect keypad electronics if the lock is properly sealed - we check gasket integrity on every install.
Biometric Lock Installation
Biometric locks are a smaller share of our Randallstown business, but demand is growing among homeowners who want keyless entry without remembering codes. Installation runs $280-$480, and these units require the same door reinforcement as smart locks - especially on Randallstown’s older steel doors where the original cutout may not match modern biometric housings. We assess the door thickness, edge spacing, and frame integrity before quoting, so you know the full cost upfront.
Electronic Lock Installation
Electronic lock installation in Randallstown covers everything from basic push-button units to networked access control for small commercial properties. Residential jobs run $160-$320; commercial master-key systems with electronic override start around $450. We service and install Medeco and Sargent electronic cylinders for Liberty Road businesses that need audit-trail capability or time-based access restrictions. Every electronic install includes a walkthrough on battery maintenance - a five-minute conversation that prevents the “my lock is dead” call six months later.
Key Duplication
Key duplication in Randallstown costs $4-$12 per standard key, with high-security Medeco or Mul-T-Lock blanks running $18-$35. We cut keys on-site for properties we rekey, and we stock Schlage, Kwikset, Yale, and Medeco keyways so you are not waiting on a parts order. For inherited homes in the 21133 ZIP, we often cut six to eight new keys after a full rekey - enough for family members, a trusted neighbor, and a hidden spare that does not live under the flowerpot.

Trusted Brands We Service in Randallstown
We install and service Schlage, Kwikset, Medeco, and Yale locks from stock carried on our Baltimore County service vehicles. For Randallstown customers, that means no waiting days for a special order on a standard deadbolt or smart lock retrofit. We also work with Mul-T-Lock, Abloy, Baldwin, and Sargent when the job calls for high-security or commercial-grade hardware. The right lock goes on the right door - not just what happened to be on the truck that morning. If your inherited Randallstown rancher has an aging Kwikset that needs replacing, we will match the finish and backset so the new hardware looks like it belongs there.
Common Lock Installation & Rekey Problems We See in Randallstown Homes
- Loose set-screws causing cylinder rotation. Original builder-grade single-cylinder deadbolts on Randallstown’s 1960s-70s homes have loose set-screws that allow cylinder rotation, causing intermittent jamming. The key turns, then doesn’t, then does again. We see this weekly in the Cherry Hill and Lyonswood areas.
- Split door casing from undersized strike plates. Undersized strike plates mounted into soft door casing split the wood over time, making the latch misalign and the door fail to close fully. We replace these with reinforced strikes and 3-inch screws into the stud framing - the fix the builder should have done in 1968.
- Swollen frames binding latches. Swollen wooden door frames from Baltimore County’s humid summers bind the latch, stressing the lock cylinder and eventually snapping the spindle. We plane the strike mortise or adjust the keeper so the door closes smoothly year-round.
- Seized locks after winter freeze-thaw. Winter freeze-thaw cycles routinely seize locks on less-used side and rear doors in Randallstown’s older homes, producing a reliable seasonal spike in service calls after the first hard freeze. A graphite treatment and weatherstrip adjustment usually prevents recurrence.

FAQs - Lock Installation & Rekey in Randallstown
The original strike plates on Randallstown’s 1960s-70s homes were undersized and screwed into soft door casing rather than the structural stud framing, so the wood splits over time and the latch loses alignment. We replace these with reinforced strikes and 3-inch screws into the stud, which is why our strike plate upgrades are among our most common Randallstown services. Call (877) 664-8139 for a free assessment of your door’s current strike.
Yes, in most cases, though the door may need a reinforced strike plate and possibly a bore adapter if the original deadbolt hole is smaller than modern standards. We rekeyed and reinforced a vintage Kwikset deadbolt on a Liberty Road split-level after the homeowner inherited the property and found the old key still worked on a previous tenant’s master cylinder. We replaced the strike plate with a 3-inch screw into the frame stud and upgraded to a Schlage smart lock with Wi-Fi capability. Call (877) 664-8139 to check your door’s compatibility.
Rekey or replace the cylinder immediately; locksmiths working the Liberty Road commercial corridor frequently find strip-mall tenant spaces with master-key cylinders that have never been re-pinned across multiple tenant turnovers, leaving prior tenants’ keys functionally valid for years. We can re-pin your existing hardware or install a new keyed-alike system with restricted keyways so old keys are permanently useless. Call (877) 664-8139 for same-day commercial rekeying.
Immediately upon taking possession, then any time a keyholder relationship changes - divorce, roommate departure, fired contractor, lost key. Randallstown’s inherited properties often come with unknown key distribution stretching back decades. We recommend starting fresh with a full rekey and counting your keys. Call (877) 664-8139 to schedule; full-home rekeys in Randallstown typically run $120-$220.
Yes, if installed with proper weatherstripping and occasional battery maintenance; the electronics themselves are not affected by cold, but swollen frames from summer humidity and ice formation in winter can bind the bolt if the door is not properly sealed. We check frame alignment and weatherstrip condition on every smart lock install in Randallstown. Call (877) 664-8139 for a winter-ready smart lock upgrade.
