Our Lock Installation & Rekey Services in Annandale
Keypad Lock Installation
Keypad locks are a practical upgrade for Annandale’s older homes, especially rental properties with frequent tenant turnover. We install Schlage and Yale keypad deadbolts that fit most existing door prep, though many of Annandale’s 1960s-era wooden doors need jamb reinforcement first. A typical keypad lock installation in Annandale runs $280-$420, including any necessary frame adjustment. For landlords along Little River Turnpike managing multiple units, we can key alike or integrate with existing master-key systems.
Key Duplication
Key duplication in Annandale isn’t just about having a spare for the housekeeper. With the area’s large, mobile immigrant population and frequent rental changes, new residents often need multiple copies fast - for family members, roommates, or backup sets for property managers. We cut standard Kwikset and Schlage keys on-site, and we stock Medeco and Mul-T-Lock blanks for the high-security cylinders common in Annandale’s commercial corridor - just ask our Automotive Locksmith in Annandale about key services for fleet vehicles too. Standard key duplication runs $4-$8 per key; high-security Medeco or Mul-T-Lock keys run $18-$35. Call (877) 664-8139 - we’ll confirm what you’ve got and quote before you come in.
Electronic Lock Installation
Electronic locks bring keyless convenience to Annandale’s aging housing stock, but installation requires honest assessment. Many of the original wooden doors on postwar split-levels lack the structural integrity for a heavy electronic deadbolt without reinforcement. Last spring we rekeyed a 1960s split-level on Valley Drive where the original Kwikset deadbolt had seized from freeze-thaw cycles. The homeowner was a military family moving in, and the sagging wooden door frame needed shimming to realign the latch - a common fix we’ve done on dozens of similar post-war brick ranchers around Annandale. Electronic lock installation with proper jamb reinforcement typically runs $340-$580 in Annandale. We won’t sell you hardware that’ll fail six months later when the frame swells.
Smart Lock Installation
Smart locks are popular with Annandale’s younger renters and tech-forward homeowners, but WiFi connectivity can be spotty in some of the area’s older homes with thicker plaster walls. We install Schlage Encode and Yale Assure locks with Z-Wave or WiFi options, and we’ll test signal strength at your door before we drill. If your 1950s split-level near Braddock Road has a weak router location, we’ll tell you upfront and recommend a bridge or extender. Smart lock installation in Annandale: $320-$560.
Biometric Lock Installation
Biometric locks - fingerprint readers - are overkill for most Annandale residences, but we install them for home offices, gun rooms, and certain commercial applications where audit trails matter. The fingerprint sensors can struggle with outdoor exposure, so we rarely recommend them for unprotected exterior doors in Annandale’s climate. When appropriate, installation runs $480-$720.
Keyless Entry Systems
Keyless entry covers everything from push-button mechanical locks to full electronic systems. For Annandale’s rental market, we favor simple mechanical push-button locks for back doors and basement entries - no batteries to fail, no programming to forget. Mechanical keyless entry installation: $220-$340. Full electronic systems with remote access: $380-$620.

Trusted Brands We Service in Annandale
We stock and install Schlage, Kwikset, and Medeco hardware from our local inventory, which means most Annandale jobs don’t wait for parts. Schlage for solid residential security at a fair price. Kwikset for reliable, widely-compatible replacement of the original locksets still common in Annandale’s postwar homes. Medeco for high-security applications - the restricted keyways and pick-resistant pins that commercial landlords along Little River Turnpike increasingly require. We also work with Yale, Mul-T-Lock, Abloy, Baldwin, and Sargent when the job calls for it. The right lock on the right door, not just what’s on the truck.
Common Lock Installation & Rekey Problems We See in Annandale Homes
- Deadbolts binding in summer humidity. Northern Virginia’s humid summers cause the wooden door frames common in Annandale’s older split-levels to swell significantly, leading to lock-bolt misalignment. We see this every July and August - the key turns hard, or the deadbolt won’t throw fully. Usually it’s frame adjustment, not a new lock.
- Original 1960s cylindrical locksets failing. Many Annandale brick ranchers and split-levels still have original or first-replacement Kwikset or Schlage knobs with worn internal mechanisms. The key spins, the latch doesn’t retract, or the cylinder pulls out with the key. We can rekey what saves and replace what doesn’t.
- Commercial master-key compatibility issues. Strip-mall landlords along Little River Turnpike often inherit master-key systems installed by previous locksmiths. When a new tenant needs rekeying, the existing Schlage knobs may not accept Medeco or Mul-T-Lock cores without cylinder replacement. We sort out what’s compatible and what’s not - before we start drilling.
- Electronic deadbolts failing on unreinforced older doors. Smart lock installation on older wooden doors where the jamb is not reinforced causes electronic deadbolts to fail under winter freeze-thaw expansion. The bolt throws, but the door frame flexes enough to jam the mechanism. We reinforce first, then install.

FAQs - Lock Installation & Rekey in Annandale
Humidity swells the wooden door frames common in Annandale’s 1950s-1970s housing stock, compressing the deadbolt against the strike plate. It’s not the lock - it’s the frame. We see this every summer on split-levels near Columbia Pike and Backlick Road. The fix is usually shimming or planing the strike area, not replacing hardware. Call (877) 664-8139 for a free look - estimates are free.
Usually yes, if the existing Schlage hardware is standard commercial grade and in good condition. We repin the cylinders to a new master-key system and issue change keys for each tenant. If the knobs are residential-grade or worn, we’ll tell you upfront - master-keying requires precise tolerances. Commercial master-key setup in Annandale strip malls typically runs $45-$85 per cylinder, plus a one-time keying chart fee. We’ve built ongoing relationships with Korean-owned property management groups in this corridor who control multiple units in the same plaza.
The lock prep usually fits, but the door itself may not. Annandale’s original 1960s wooden doors often lack the structural integrity and jamb reinforcement that electronic deadbolts require. We assess the door thickness, frame condition, and strike area before quoting. If reinforcement is needed, we include it in the flat price - no surprises. Typical keyless entry installation on an Annandale brick rancher: $280-$420 depending on prep work. Call for an exact quote.
Immediately, and then after every tenant turnover. Annandale’s large immigrant population and mobile rental market mean keys change hands frequently - previous tenants, their relatives, cleaning crews, contractors. You don’t know who has a copy. For landlords, we recommend rekeying between every lease and maintaining a master-key system for efficient turnover. Residential rekeying in Annandale runs $18-$32 per cylinder. Call (877) 664-8139 - we’ll schedule around your move-in date.
Yes, in most cases. A stuck key usually indicates a worn key, debris in the cylinder, or a damaged pin - not necessarily a failed core. We can extract the key, clean and inspect the Mul-T-Lock cylinder, and repin it to a new key combination without replacing the entire high-security cylinder. This saves $150-$300 over full replacement. Mul-T-Lock rekeying for Annandale commercial accounts: $45-$85 per cylinder. Call (877) 664-8139 - we stock Mul-T-Lock blanks and pins for same-day service.
