Fast, Reliable Residential Locksmith Across Los Angeles
If you’re locked out of a mid-century apartment in Koreatown or need a smart lock installed on a 1920s Craftsman in Echo Park, the number to call is (409) 405-4485. Preston Locksmith & Security handles residential locksmith work across Los Angeles with a live trackable arrival time and a written price confirmed before any tech is dispatched. We know the hardware this city throws at us – aging mortise locks, painted-over deadbolts, worn cylinders in doors that have seen forty years of tenants. Call us, get a real person, and get a price that won’t change when the van pulls up.
Los Angeles is not a single neighborhood waiting around for a unified housing stock. From pre-war brick walk-ups in Westlake to stucco bungalows in Van Nuys, every street has its own lock story. We dispatch locally, arrive fast, and bring what the job actually needs – including mortise-specific tooling you won’t find in a typical van. No call center runaround. No “we’ll be there sometime Tuesday.” Just a phone number, a live person, and a tech on the way with a price already in writing.
Why Preston Locksmith & Security Is Los Angeles’s Preferred Residential Locksmith Company
We’re led by Kevin Yoon, and the company has been doing this since 2008. That’s a long time to learn the specific ways Los Angeles locks fail. We know that a 1930s courtyard apartment building in Silver Lake has different hardware than a 1990s condo complex in Playa Vista, and we stock cylinders, cam locks, and tailpieces for both. Our techs are background-checked, uniformed, and you see their photo and live arrival time before they knock.
Every call includes The Relay Visibility Guarantee: a written price before work begins, a live trackable arrival time, before-and-after photos of the job, and a written guarantee on the repair. If the repair fails within 365 days under our Done Right Promise, we return and make it right – free second visit, no argument. That’s the standard Kevin Yoon runs, and it’s why Los Angeles homeowners and property managers keep our number saved.
We built our reputation in Los Angeles on being specific. Rekeying a standard lock typically runs $65-$95 per cylinder, lock change jobs range from $85-$180 depending on hardware, and residential lockout service starts around $75-$120, with the final number confirmed on the phone before anyone is dispatched. Smart lock installation runs $150-$300 per unit, including mounting, alignment, programming, and testing. You’ll never hear a teaser price from us and then meet a different number on the sidewalk.
Smart Lock Installation in Los Angeles
Smart lock installation in Los Angeles is one of our most requested residential services, especially in neighborhoods like Santa Monica, Culver City, and the Arts District where renters and owners alike want keyless entry and remote access. The work involves removing the existing deadbolt or mortise cylinder, prepping the door for the new smart lock footprint, mounting the exterior and interior escutcheons, fresh batteries, programming codes or app access, and testing the deadbolt throw and alignment. A written price before work starts means you know exactly what it costs before a single tool leaves the bag.
In Los Angeles, a surprising number of smart lock installs hit the same snag: the door was prepped for an old mortise lock, not a modern cylindrical deadbolt. That means the tech has to carefully bore or adapt the door without splintering the face. We carry faceplates, reinforcement plates, and longer tailpieces to make the retrofit clean. Expect $150-$300 per lock, confirmed in writing, with no surcharge added on arrival.
What the install actually involves
Our tech removes the old hardware, checks the cross-bore alignment, and mounts the smart lock so the deadbolt throws smoothly without binding. We then calibrate the motor, pair the lock with your phone or keypad, and walk you through setup. Before-and-after photos are included on every job.
Brands we install most often in LA
We see a lot of Schlage Encode, Kwikset Halo, and Yale Assure units in Los Angeles homes. We’re trained on all three and can usually complete the install in under an hour per lock.
Locked Out of Apartment in Los Angeles
Locked out of an apartment in Los Angeles is the call we get at 2 a.m. from a tenant in a 1940s courtyard building off Wilshire, or at 6 a.m. from someone who left their keys in a rideshare. We respond across Los Angeles – from Huntington Park up through South Gate, Bell, and Maywood – with a live arrival time you can track from your phone. Most residential lockouts can be opened without drilling, which matters in a city with this much original wood-frame hardware.
Before we touch the door, we verify you actually live there. Los Angeles has high tenant turnover and a lot of sublets, so our techs check ID, a lease, a utility bill, or a key ring that matches. If you’re locked out of a shared building, we also confirm with a property manager when one is listed. That’s a safety protocol, not a delay – it usually takes ninety seconds.
A non-destructive lockout in Los Angeles typically runs $75-$120 depending on time of day and hardware type. If drilling becomes necessary – usually because the lock has been painted shut or the cylinder is seized – we’ll tell you the exact cost before we drill, and the price you approved on the phone is the price on the invoice. No call-out surcharge added at the door.
Non-destructive entry first
We start with picks, shims, and bypass tools before ever reaching for the drill. In older Los Angeles apartment buildings, the mortise locks respond well to picking, and the door face stays clean.
When drilling is the only option
Sometimes a lock has been painted so many times in a Koreatown or Westlake apartment that the cylinder is a solid block. We’ll drill only after showing you the dead cylinder and confirming the added cost in writing.
Trusted Brands We Service in Los Angeles
We stock and service Schlage, Kwikset, and Medeco hardware across every Los Angeles call, from a Baldwin handleset on a Hancock Park front door to a Mul-T-Lock cylinder on a West Hollywood rental. Our vans carry common cylinders, tailpieces, and strike plates so we don’t have to run across town for parts. If your Los Angeles home runs Medeco high-security keys, we can duplicate and rekey without sending you to a specialty shop. Same for Schlage and Kwikset – those are the two we see most in single-family homes from Mid-City to Studio City.
Common Residential Locksmith Problems We See in Los Angeles Homes
- Aging mortise locks in pre-war and mid-century buildings. Los Angeles has one of the highest concentrations of pre-war and mid-century apartment buildings in the country, which means a huge share of residential locksmith work here involves aging mortise locks and original pin-and-tumbler cylinders in wood-frame doors rather than modern bored deadbolts. Our techs carry mortise-specific tooling and stock cylinders on every van to handle these without drilling or replacing the entire lockset.
- Painted-over deadbolts and latches. Landlords and previous owners in Los Angeles love a fresh coat of paint, and often that paint goes right over the lock. A seized latch or stuck keyway from paint buildup is one of the most common failures we see between Silver Lake and Highland Park.
- Misaligned strike plates from foundation settling. Los Angeles sits on varied soil, and older homes settle. That shifts door frames, which makes the deadbolt bind against the strike plate. We re-align, shim, or replace the strike so the bolt throws cleanly.
- High tenant turnover with unreturned keys. Los Angeles rental turnover is constant. Property managers call us weekly to rekey between tenants. A rekey – swapping the internal pins so old keys no longer work, no new hardware needed – runs $65-$95 per cylinder and keeps the same door hardware intact.

FAQs About Residential Locksmith in Los Angeles
Yes, in most cases. Over 90% of residential lockouts in Los Angeles are opened with picks, shims, or bypass tools – no drilling, no damage to the door or the lock. If the cylinder is seized or painted shut, drilling becomes necessary, and we’ll confirm the exact cost in writing before the drill touches the lock. Call (409) 405-4485 and ask for a non-destructive opening estimate.
Yes. Rekeying – swapping the internal pins so old keys no longer work, no new hardware needed – runs $65-$95 per cylinder in Los Angeles. Replacing the lock hardware entirely runs $85-$180 depending on the brand and finish. If the existing lock is in good shape, rekeying is almost always the cheaper and smarter move. We’ll tell you which one actually makes sense for your door before quoting a price.
We remove the old deadbolt or lockset, confirm the cross-bore alignment works with the smart lock’s footprint, sometimes adapt the door to fit, mount the interior and exterior escutcheons, install fresh batteries, pair the lock with the app or keypad, and test the deadbolt throw. The whole job typically takes under an hour and runs $150-$300 per lock in Los Angeles, confirmed in writing before work starts. Call (409) 405-4485 to schedule.
Before the tech is dispatched, you’ll get a photo, their name, and a live trackable arrival time through The Relay Visibility Guarantee. They arrive in a Preston uniform with company ID. We never send anonymous contractors. If anyone shows up at your Los Angeles door claiming to be us without that information, call us immediately.
This is the biggest complaint in Los Angeles locksmith work: a teaser price quoted on the phone, then a higher number once the tech sees a mortise lock or a painted-shut deadbolt. That doesn’t happen with us. We ask about your building age and hardware on the phone, quote a firm price, and that number is the invoice number. The only time a lockout costs more than the initial quote is if we both agree drilling is necessary, and we show you the dead cylinder before we start. Call (409) 405-4485 and you’ll get the actual price, not a teaser.
