A lock that has started to fight you is usually telling you something. The key turns only halfway, the deadbolt needs a shoulder against the door to engage, the handle wobbles, or the latch no longer catches the strike plate. In Covina, where so many homes have been lived in for decades, these problems tend to build slowly and then fail at an inconvenient moment, like a late night when you cannot get the door to lock behind you.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent a long career on exactly the kinds of hardware found across the San Gabriel Valley. We are fully mobile. There is no storefront to visit; we bring the tools, common parts and know-how to your door, any hour of the day or night.
Lock repair is not the same as replacement, and we treat it that way. Many sticking or loose locks can be restored by cleaning, adjusting, re-aligning the strike, tightening or replacing a worn internal part, or fixing the door fit that is really causing the trouble. When a lock is truly worn out or damaged, we will say so plainly and explain your options, including whether an upgrade makes sense. You decide what happens next.
How it works in Covina
- 1
Call and describe the symptoms
Phone (323) 997-8867 and tell us what the lock is doing: sticking, spinning freely, jammed with a key inside, loose on the door, or not latching. Details like the brand, the door type and whether it is a deadbolt, knob, lever or older mortise lock help us arrive prepared.
- 2
We come to you
We are mobile and available 24/7, so a technician travels to your Covina address, whether that is a bungalow near Citrus Ave, a ranch home in Covina Hills or a unit in an apartment building.
- 3
Diagnose the real cause
Before touching a part, we test the lock with the door open and closed. Many problems that look like a bad lock are actually a door that has shifted, a strike plate that no longer lines up, or swollen or settled framing. Finding the true cause avoids replacing hardware that was never the problem.
- 4
Repair, adjust or service
Where possible we fix what you have: re-aligning latches and strikes, tightening or replacing worn components, clearing debris, lubricating correctly, and repairing or reconditioning older mortise and rim locks that are common in 1920s and 1930s buildings.
- 5
Test and explain your options
We operate the lock repeatedly from both sides with your keys and confirm the door secures properly. If the hardware is beyond reasonable repair, we explain the alternatives, such as replacement or rekeying, before any work proceeds.

What affects the price
- The type of lock involved: a standard residential deadbolt, a knob or lever set, an older mortise lock and a high-security cylinder each call for different parts and labor.
- Whether the problem is the lock itself or the door and frame, since alignment and strike adjustments differ from internal component repair.
- Parts needed, including whether components for an older or less common lock are readily available.
- Whether a broken key must be extracted or a jammed mechanism disassembled before repair can begin.
- The time of day and how urgent the situation is, as after-hours and emergency calls differ from scheduled visits.
- Whether you decide to replace or upgrade the lock after we inspect it, or have us repair the existing hardware.
Why Covina chooses us
- Fully mobile since 1987: we work at your door, so you are not carrying a lock or door to a shop.
- Repair first: we try to restore the hardware you already have, and we tell you honestly when replacement is the smarter choice.
- Experience with older hardware, including the mortise and rim locks found in historic bungalows and early commercial buildings.
- Door-and-frame diagnosis: we look at alignment and fit, not just the lock body, so the fix lasts.
- Open 24/7, so a lock that fails at night does not have to wait for morning.
- Direct involvement from owner and lead technician David Shar, with plain explanations and no pressure.
Lock Repair across Covina
Covina is an established San Gabriel Valley city with a mix of housing that makes lock repair surprisingly varied. In and around Downtown Covina, near Citrus Ave, Heritage Plaza and the Covina Center for the Performing Arts, you will find Craftsman and Spanish bungalows and commercial buildings from the 1920s and 1930s. Original mortise locks and older rim locks are common there, and after a century of use, worn latches, loose escutcheons and sticky cylinders are a regular reason to call. Small retail doors in the downtown core see heavy daily use and develop their own alignment problems.
Further east, Charter Oak (91724) is largely post-war single-family tract housing, where original builder-grade deadbolts and knobsets are now many years old and often loosening or binding. South of downtown, Covina Hills brings ranch-style and larger-lot homes, with side gates, garage entry doors and multiple exterior doors that each need to work reliably. We also serve the 91722 and 91723 ZIP codes and the neighborhoods around them.
Whether you are near Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd or Arrow Hwy, or commuting along Interstate 10 or from the Covina Metrolink station, our mobile service comes to wherever the door is. Call (323) 997-8867 any time.
