Our Lock Installation & Rekey Services in Covina
Smart Lock Installation
Covina’s older homes present real challenges for smart lock installation. Those wood-framed doorways in the 1950s tracts have settled and shifted for seventy years, so the standard smart lock template doesn’t always land square. We measure the actual backset, check for frame twist, and install Schlage Encode or Yale Assure locks with proper reinforcement plates - not the plastic adapters that crack after two seasons of Covina heat. We also walk you through the app setup before we leave, because a smart lock you can’t operate isn’t smart at all.
Keyless Entry Systems
Keyless entry is popular with Covina families who’ve had kids lose house keys for the third time, and with aging homeowners who’d rather punch a code than fumble with keys at the door. We install keypad deadbolts that stand up to the San Gabriel Valley’s temperature swings - the cheap units from big-box stores fail fast when summer hits 105°F and the electronics cook. We stock Kwikset SmartKey and Schlage keypads with proper weather sealing, and we set your code to something you’ll actually remember.
Keypad Lock Installation
Keypad locks work well on Covina’s side-entry doors and garage man-doors, where you’re often carrying groceries or tools and don’t have a free hand. We see a lot of these installs on the ranch-style homes in the 91724 area, where the original single-cylinder deadbolt gets upgraded to a backlit keypad for evening access. We check your door thickness and bore diameter - older Covina doors are often 1-3/8″ rather than the modern 1-3/4″ standard - and we bring the right hardware so we don’t have to make two trips.
Biometric Lock Installation
Biometric locks - fingerprint readers - are finding their way onto Covina homes where multiple family members need access and nobody wants to manage spare keys. These units demand precise alignment and clean power, so we run voltage tests at your door and shim the strike plate if your frame has settled out of square. We recently installed a biometric unit on a home near Badillo Street where the original mortise lock had been converted poorly; we rebuilt the prep and got the fingerprint reader seating clean.
Electronic Lock Repair & Replacement
Covina’s summer heat kills electronic locks. The battery compartments swell, the circuit boards delaminate, and the touchpads go intermittent. We carry replacement electronic locksets from Schlage, Yale, and Kwikset, and we can often swap a failed unit same-day if you call early. We also handle the less common stuff - electrified strikes on Covina’s few commercial walk-ups, and mag-locks on accessory dwelling units where the homeowner added a rental.

Common Lock Installation & Rekey Problems We See in Covina Homes
- Summer lock binding from heat-expanded frames. Covina’s inland location produces summer highs of 95-105°F, causing wood door frames to swell and metal edges to expand against steel jambs. Every June through September, we field a surge of calls from residents whose deadbolts won’t throw without lifting the handle or shoving the door. It’s not the lock - it’s the frame. We realign the strike plate and often install an extended plate so the bolt lands clean.
- Worn 1950s Kwikset pins that crumble during rekeying. The original brass pins in Covina’s post-war Kwikset locks have been cycling for sixty-plus years. When we pull the cylinder to rekey, the pins sometimes disintegrate. We don’t charge you for the surprise - we quote replacement upfront, install a modern Schlage or Kwikset SmartKey cylinder, and get you working keys that turn smooth.
- Settled foundations creating out-of-square doorjambs. The slab-on-grade construction common in Covina’s 1950s-1970s tracts shifts with soil moisture and decades of earthquakes. The result: a door that latches only if you pull up, push down, or lean on it. We diagnose whether the fix is strike-plate relocation, jamb shimming, or full hinge adjustment - and we do it, not just sell you a new lock.
- Mortise locksets in pre-war homes near Citrus Avenue. Those 1920s-1930s Craftsman bungalows still carry original mortise locks that most big-box locksmiths won’t touch. We have the specialty tools and the patience to rebuild or replace these units without damaging the vintage door prep.

FAQs - Lock Installation & Rekey in Covina
Your deadbolts stick because Covina’s 95-105°F summer heat swells wood door frames and expands metal door edges against steel jambs, throwing off the precise alignment your lock needs. This is a predictable seasonal pattern in inland San Gabriel Valley homes that coastal locksmiths rarely encounter. We fix it by realigning or extending the strike plate so the bolt throws clean even when the frame shifts. Call (877) 664-8139 - estimates are free, and we carry the extended plates on every van.
Yes, we rekey vintage Kwikset locks regularly in Covina’s post-war tracts, though the original brass pins sometimes crumble after sixty years of use. When that happens, we quote a replacement cylinder upfront - no bait-and-switch - and install modern hardware that fits your door without new holes. We recently rekeyed a 1950s tract home on Cypress Street near downtown where the original Kwikset deadbolt was binding from decades of frame settling and heat expansion. We replaced it with a Schlage B560 and installed an extended strike plate, correcting the lift-handle workaround the owners thought was normal.
Yes, and we do it differently than installers who treat every door like new construction. We measure your actual backset, check for frame twist from foundation settling, and use reinforcement plates rather than plastic adapters. Older Covina doors are often 1-3/8″ thick instead of the modern 1-3/4″ standard, so we bring the right hardware the first time. Smart locks on settled frames work fine when they’re installed by someone who knows what to look for.
Standard rekeying in Covina runs $45-$75 per cylinder, with most three-bedroom homes falling in the $135-$225 range for full rekeying. If your vintage Kwikset pins have degraded and need replacement, that adds $40-$80 per cylinder - quoted upfront, never as a surprise. We honor our standing $50-off repair-over-$250 offer and our 5% senior/veteran discount on every rekey. Call (877) 664-8139 for an exact quote - estimates are free.
Most standard lock installations on Covina’s ranch and tract homes take 45 minutes to 1.5 hours, depending on whether we need frame realignment or strike-plate extension. Smart lock installations with WiFi setup run closer to 1-2 hours. Mortise conversions on pre-war homes near Citrus Avenue take longer - typically 2-3 hours - because we preserve the vintage door prep. We give you a time estimate when we quote, and we don’t leave until the lock operates smooth and you’ve tested it yourself.
