Fast, Reliable Lock Installation & Rekey Across Covina
Lock installation and rekeying in Covina typically runs $120-$380 depending on hardware grade, with most residential jobs completed same-day. Our Lock Installation & Rekey team covers all three Covina ZIP codes - 91722, 91723, and 91724 - with technicians usually on-site within 45 minutes during business hours. Call (833) 294-4584 for a flat price before we roll.
We’ve worked Covina’s streets for over 42 years, from the postwar ranch blocks south of Badillo Street to the older homes near the historic core around Larkwood Avenue. That familiarity matters when you’re dealing with 60-year-old hardware that doesn’t match anything in the current catalog. We know which frame reinforcements the 1950s tract builders skipped, where the original Kwikset deadbolts are failing in clusters, and how the San Gabriel Valley heat island turns a simple rekey into a full replacement more often than you’d expect.

Our Lock Installation & Rekey Services in Covina
Smart Lock Installation
Smart lock installation in Covina’s 1950s-60s ranch homes demands more than screwing a new deadbolt into old wood. The original door prep on these houses was done for basic pin tumbler deadbolts, not the thicker bore and reinforced strike plates that smart locks require. We retrofit the frame, install proper backset alignment, and make sure your Wi-Fi bridge reaches from the router to the front door - a real issue on some of Covina’s deeper lots. Typical smart lock installation in Covina runs $280-$450 including hardware prep and frame reinforcement.

Keyless Entry
Keyless entry systems give Covina homeowners who’ve been in the same house for twenty-plus years a way to stop hiding keys under the planter. We install keypad deadbolts that work with Covina’s existing door prep where possible, upgrading the strike and faceplate where the original builder-grade setup won’t hold. For homes near the historic core with knob-only entry sets, keyless entry often means a full retrofit: adding a deadbolt where none existed, running wire for electronic strikes if needed, and making it all look like it belongs on a mid-century ranch. Keyless entry installation in Covina typically costs $220-$390.

Keypad Lock
Keypad locks are the practical choice for Covina’s rental properties and multi-generational households, where you need codes that can be changed without rekeying the cylinder. We install standalone keypad deadbolts and hardwired systems for larger homes in the Charter Oak-adjacent areas. The heat here matters: we specify keypads rated for 100°F+ operation because standard consumer-grade electronics fail early in Covina’s inland climate. Keypad lock installation runs $190-$340 in Covina.

Biometric Lock
Biometric locks - fingerprint readers - are increasingly requested by Covina homeowners who want keyless access without remembering codes. Installation on older ranch doors requires careful frame assessment; swollen summer wood can stress the latch mechanism if the strike isn’t properly shimmed. We see this binding issue more in Covina than in cooler foothill cities. Biometric installation typically runs $320-$480.

Electronic Lock
Electronic locks cover everything from basic motorized deadbolts to full access control systems. For Covina’s commercial strip along Azusa Avenue and the small office parks near the 10 Freeway, we install electronic strikes, maglocks, and timed access systems. Residential electronic lock work in Covina focuses on retrofitting smart connectivity into homes where the wiring was never intended for it.

Key Duplication
Key duplication in Covina is not just running a blank through a machine. The original Kwikset and Schlage keys from 1960s tract homes often have wear patterns that standard duplicators misread, producing copies that work poorly in already-worn cylinders. We cut by code where possible, using factory specifications rather than tracing a worn original. Key duplication runs $4-$18 per key in Covina, with high-security Medeco or Mul-T-Lock blanks at the higher end.

Trusted Brands We Service in Covina
We stock and install Schlage, Kwikset, Medeco, and Yale on every Covina service call - not because we carry everything, but because these are the brands that hold up in our inland heat. Schlage B560 and B660 series deadbolts handle frame swelling better than lighter-grade hardware. Kwikset’s SmartKey cylinders let us rekey on-site without removing the lock, a real time-saver when we’re working a full day across 91722, 91723, and 91724. Medeco and Yale come into play for homeowners who want pick-resistant and bump-resistant security without going full commercial. We keep common Covina replacement parts on the truck: strike plates with adjustable lips, longer screws for frame reinforcement, and shim kits for the seasonal alignment issues this climate creates.
Common Lock Installation & Rekey Problems We See in Covina Homes
- Thermal frame swelling binds deadbolts. Covina’s 100-108°F summer highs swell wood door frames enough to pinch deadbolt throws against misaligned strike plates. We adjust the frame, shim the strike, and often upgrade to a deadbolt with more throw tolerance - a repair pattern we see far more here than in Glendora or Azusa.
- Original 60-70-year-old pin tumbler cylinders fail from grit infiltration. Santa Ana winds push fine chaparral dust into exterior keyways, accelerating wear on already-aged Kwikset and Schlage cylinders. Rekeying a worn cylinder is temporary; full replacement with modern hardware is usually the honest recommendation.
- Knob-only entry sets with no deadbolt. On residential blocks near Covina’s historic core, we still encounter mid-century homes that never received a deadbolt upgrade. This is a full retrofit: boring the door, reinforcing the frame, and installing proper strike hardware where none existed.
- Clustered hardware failure across postwar tracts. Covina’s 1945-1965 housing stock is reaching end-of-life simultaneously. We get calls from neighbors on the same block within weeks of each other, all with original deadbolts that have finally given out. Bulk scheduling for adjacent homes is common.
We responded to a home near the historic core on Larkwood Avenue where a mid-century knob-only entry set had never been upgraded. The original builder-grade deadbolt on the back door had seized from thermal warping, and the front still lacked any deadbolt. We replaced both with Schlage B560 deadbolts, reinforced the frames, and rekeyed to match a single key - eliminating a 60-year security gap.

FAQs - Lock Installation & Rekey in Covina
Your deadbolts bind in summer because Covina’s inland heat bowl pushes temperatures 10-15°F above coastal LA, causing wood door frames to swell and shift strike plate alignment. We see this constantly in 91722, 91723, and 91724. The fix is usually a combination of strike plate adjustment, longer screws for frame pull, and sometimes a deadbolt with more throw clearance. Call (833) 294-4584 for an exact quote - estimates are free.
You can rekey it, but we often advise against it. The original Kwikset or Schlage cylinders in Covina’s 1950s-60s tract homes have decades of Santa Ana grit wear, and rekeying a worn cylinder produces a key that works poorly and fails soon after. Replacement with modern hardware is usually the better value. Call (833) 294-4584 for an exact quote - estimates are free.
You should add a deadbolt, and likely replace the knob with a passage set while you’re at it. We encounter this exact scenario on older blocks near Covina’s historic core - a security gap that made sense in the 1950s citrus-belt suburb but doesn’t now. We bore the door, reinforce the frame with a strike box, and match everything to one key. Call (833) 294-4584 for an exact quote - estimates are free.
Yes, but older wooden doors in Covina require frame reinforcement and proper backset alignment that newer doors don’t. The original door prep from the 1950s-60s is often too shallow or misaligned for smart lock specifications. We handle the retrofit, including Wi-Fi bridge placement for Covina’s deeper lots. Call (833) 294-4584 for an exact quote - estimates are free.
Santa Ana winds push fine chaparral grit into exterior keyways, accelerating pin tumbler wear and causing keys to stick or jam. In Covina, this combines with already-aged cylinders to produce failure modes we don’t see at the same rate in less dusty or newer housing markets. Periodic cleaning helps; eventually cylinder replacement is necessary. Call (833) 294-4584 for an exact quote - estimates are free.
