Our Lock Installation & Rekey Services in North Kensington
Smart Lock Installation
Adding a smart lock to a North Kensington home takes more than drilling fresh holes. The wooden door frames in 20895 have settled over 70-100 years, and standard smart lock templates often misalign with existing bore holes. We measure frame squareness, check for seasonal swelling patterns, and select smart locks from Yale and Baldwin that tolerate slight misalignment without binding. For homes near the historic core where preserving original exterior hardware matters, we can install smart locks on secondary doors or integrate them with existing mortise systems where possible.
Keyless Entry
Keyless entry systems in North Kensington need to withstand Washington DC’s humidity swings and the physical wear of daily use on older doors. We install keypad and touchscreen systems that mount securely to settled frames without stressing the latch mechanism. Many of our North Kensington customers choose keyless entry for side or basement doors while keeping original front-door hardware intact. We program codes on-site, show you how to add or delete users, and leave written instructions that don’t require a computer science degree to follow.
Keypad Lock Installation
Keypad locks suit North Kensington’s rental properties and multi-generational households where multiple people need access without key duplication. We install commercial-grade keypad locks from Sargent and Schlage that hold up to heavy use, and we can rekey the cylinder to match your existing keying system. For homes with original mortise locks, we sometimes install keypad locks on interior doors or gates to add security layers without altering historic exteriors.
Key duplication in North Kensington isn’t always straightforward. The skeleton keys and antique bit keys found in 20895 homes require specialized blanks and cutting equipment that most hardware stores no longer stock. We maintain an inventory of period-correct key blanks and can duplicate most antique keys while you wait. For mortise locks with worn or non-standard keyways, we can fabricate working keys from the lock itself.
Biometric Lock Installation
Biometric locks are gaining traction in North Kensington among homeowners who want keyless access without remembering codes. We install fingerprint-enabled deadbolts from premium manufacturers, with particular attention to the frame alignment issues that plague older homes. These systems require precise strike plate positioning to function reliably, and our experience with North Kensington’s settled construction means we get the mechanical fit right before we program the electronics.

Common Lock Installation & Rekey Problems We See in North Kensington Homes
- Deadbolt misalignment after winter. Washington DC’s freeze-thaw cycles swell wooden door frames in cold months, then contract them in summer. A deadbolt that worked in October binds by February. We adjust strike plates and sometimes rehang doors to compensate for seasonal movement.
- Modern deadbolts installed on settled frames without strike adjustment. The bolt throws, but the angle is wrong. It wears the strike plate, stresses the latch mechanism, and eventually fails to engage. We see this on recent “handyman” installations throughout 20895 and correct the underlying alignment.
- Antique mortise locks condemned to replacement. Too many locksmiths tell North Kensington homeowners their skeleton-key hardware is unfixable. Often we can rebuild the lock body, fabricate or source replacement springs and cams, and rekey to a new bitting. The homeowner keeps their original hardware; we earn a customer for life.
- Smart lock failure from improper mounting on warped doors. The electronics work fine, but the bolt drags or the auto-lock feature strains the motor. We check door flatness and frame squareness before we specify any smart lock for a North Kensington installation.

FAQs - Lock Installation & Rekey in North Kensington
Yes, in most cases we can rekey or rebuild antique mortise locks while preserving the original hardware. We recently rekeyed a set of antique mortise locks on a 1930s bungalow on Plyers Mill Road where the homeowner wanted to keep the original hardware. We sourced period-correct internal components and adjusted the bolt throw to compensate for decades of frame settling, preserving the home’s character while upgrading security. If the lock body is cracked or a critical part is unobtainable, we’ll tell you honestly and discuss options. Call (844) 314-7347 for a free assessment.
Your wooden door frame has swollen from Washington DC’s freeze-thaw moisture cycle and will likely contract again in summer. This is extremely common in North Kensington’s older homes with original wooden frames. We adjust the strike plate position, sometimes rehang the door slightly, and check that the bolt throw clears properly at both extremes of frame movement. Temporary fixes that ignore the seasonal cycle fail by summer. Call (844) 314-7347 and we’ll solve it properly.
Yes, but we select models and mounting methods that tolerate the frame settlement and slight warping common in 20895 homes. We measure your door’s actual conditions before recommending hardware. Yale and Baldwin both make smart locks with adjustable strike mechanisms that perform better on older doors. We won’t sell you a lock that will fail in six months because the frame shifted. Call (844) 314-7347 to discuss your specific door.
Yes, we duplicate antique bit keys and skeleton keys from our inventory of period-correct blanks. Most North Kensington jobs take 15-30 minutes while you wait. If your original key is too worn to duplicate directly, we can decode the lock itself and fabricate a working key. Hardware stores in Montgomery County rarely stock these blanks anymore. Call (844) 314-7347 before you make a wasted trip.
