Lancaster has a lot of doors that have been working hard for a long time. Many of the stucco two-story tract homes built out in the 1980s through the 2000s still carry their original builder-grade hardware, and years of desert sun, wind-blown dust and daily use take a toll. Latches get sticky, keys start to bind, deadbolts stop throwing all the way, and finishes flake. When a lock reaches that point, replacing it is often a better answer than patching it.
Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while the hardware stays. Replacement swaps the hardware itself, which makes sense when the lock is physically damaged, the cylinder has degraded, the style no longer suits the door, or you want a higher grade of security. We will tell you honestly which one fits, because sometimes a rekey is all you need and costs less.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward advice. We are fully mobile. There is no storefront to visit; we bring hardware and tools to your door in Lancaster at any hour, including nights and weekends, and we do the work on the spot.
How it works in Lancaster
- 1
Tell us about the door and the problem
Call (323) 997-8867 and describe what is going on: a sticking deadbolt, a broken handle, a lock left damaged after a break-in, or a property you simply want updated. Mention whether it is a front door, patio slider, garage entry, or a commercial storefront, since each takes different hardware.
- 2
On-site inspection
We look at the lock, the door, the strike plate and the frame. In Lancaster, sun-faded finishes, loose screws and worn strike plates are common, and a new lock in a poorly aligned door will not last. We point out anything that needs attention before we install.
- 3
Choose the right hardware
We walk through options in plain terms: grade of deadbolt, handle style, finish, smart or keypad choices where they make sense, and whether you want all locks keyed alike. You decide based on how the property is used, whether it is your own home, a rental or a business.
- 4
Removal and installation
We remove the old hardware and fit the new lock, adjusting the latch, bore and strike plate so it throws smoothly. Where a door has been damaged, we address reinforcement of the strike area so the new lock has something solid to bolt into.
- 5
Testing and key handoff
We cycle the lock repeatedly with the door open and closed, confirm every key works, and hand over keys. For rentals or vacant homes, we can set up keying so a property manager holds a clear record of what opens what.

What affects the price
- The type and grade of lock you choose, from basic builder-grade to heavier-duty deadbolts and electronic or keypad models.
- How many locks are being replaced, and whether you want them all keyed alike to a single key.
- Door and frame condition, since a damaged jamb or misaligned strike may need repair for the new lock to work properly.
- Commercial versus residential hardware, such as aluminum storefront-door cylinders that differ from standard house locks.
- Time of day and urgency, because after-hours and emergency calls differ from scheduled work.
- Finish and specialty requirements, including matching existing hardware or specific appearance and security features.
Why Lancaster chooses us
- Fully mobile service. We do the work at your property, so there is no shop trip and no leaving a door unsecured while you travel.
- Open 24/7, including overnight and weekends, which matters after a break-in or when a lock fails at an awkward hour.
- In business since 1987 under owner David Shar, so the advice comes from decades of seeing which hardware holds up.
- Honest replace-versus-rekey guidance. If your current lock is sound, we will say so rather than sell you something you do not need.
- Experience across housing types, from tract homes and older bungalows to apartments and strip-center storefronts.
- We check the door and strike plate, not just the lock, so the new hardware actually performs.
Lock Replacement across Lancaster
Lancaster's housing mix shapes the lock work we see. In East Lancaster, vacant and previously foreclosed tract homes often need locks replaced or rekeyed and a lockbox installed so agents and contractors can get in without handing out copies. Around The BLVD and the older downtown bungalows, rental turnover means locks get worn quickly, and property managers near Lancaster Boulevard often want fresh hardware between tenants. In West Lancaster and Quartz Hill, many stucco two-story homes still run original builder-grade deadbolts that are due for an upgrade.
We serve ZIP codes 93534, 93535 and 93536, from the neighborhoods near William J. Fox Airfield out to the Avenue J, Avenue K and Avenue L grid and along 10th Street West and 20th Street East. Strip centers along Avenue K bring a different job: aluminum storefront doors where the cylinder has been degraded by years of UV exposure, or where a break-in has left the lock damaged and needing replacement.
Whether you are near the Antelope Valley Fairgrounds, off Sierra Highway, or just off the CA-14, we come to you. Call (323) 997-8867 any time and we will plan the right replacement for your door.
