A lock does not fail all at once. It gets stiff, the key starts to stick, the deadbolt needs a lift and a shove, or the latch no longer catches the strike plate. In Simi Valley, where so many homes were built between the 1960s and 1990s, plenty of front doors still carry their original hardware, and decades of daily use take a toll. Replacing the lock is often the simplest way to make a door feel solid and secure again.
Lock replacement is also the right answer after certain events: a tenant moves out, a roommate leaves without returning keys, a key goes missing, or a break-in attempt leaves the cylinder or strike damaged. Sometimes a rekey is enough, and we will tell you honestly when it is. When the hardware itself is worn, bent, or below the grade you want, a new lock is the better investment.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to drive to. We bring the work to your door, whether that is a ranch home near Texas Tract, a gated home in Wood Ranch, or a shop on Cochran Street.
How it works in Simi Valley
- 1
Tell us about the door
Call (323) 997-8867 and describe what is happening: sticking key, loose handle, damaged latch, or a recent move-out. Mention the door type and whether you want a basic deadbolt, a higher-grade lock, or a smart lock.
- 2
Inspect the existing hardware
On site, we look at the lock, the door prep, the strike plate and the frame. Worn hardware is sometimes only part of the problem, so we check that the door closes and latches properly before choosing a replacement.
- 3
Choose the right replacement
We go over options that fit your door and your goals, from standard residential deadbolts to sturdier grades and keypad or smart models. If your HOA requires specific finishes or hardware, we match to that so the exterior stays consistent.
- 4
Install and align
We remove the old lock and fit the new one, aligning the bolt, latch and strike so it throws smoothly without force. Where needed we reinforce or adjust the strike plate for a more secure fit.
- 5
Key and test everything
We key the new locks as you need, including keyed-alike sets so one key works at several doors. We cycle every lock from inside and outside, hand over the keys, and show you how any smart features work.

What affects the price
- The type of lock chosen: a basic deadbolt, a higher-security grade, a handle set, or a keypad or smart lock all differ in hardware cost.
- How many doors or locks are being replaced, and whether you want them keyed alike.
- Whether the door or frame needs extra work, such as enlarging a bore, repairing a damaged edge, or replacing a worn strike plate.
- Finish and style requirements, including HOA-specified hardware in planned communities.
- Whether the visit is during regular hours or an after-hours emergency, such as replacing locks after a break-in.
- Commercial hardware like panic bars or storefront locks, which involve different parts and installation than residential locks.
Why Simi Valley chooses us
- Fully mobile, 24/7 service, so replacement can happen at your door even late at night or on a weekend.
- In business since 1987, with owner David Shar leading the work and familiar with the hardware found in older tract homes.
- We tell you honestly whether a rekey will do or a full replacement is warranted, so you do not pay for more than you need.
- Experience with both residential and commercial hardware, from worn Kwikset and Schlage deadbolts to storefront locks and panic devices.

- We test every lock after installation and walk you through keys and any smart features before we leave.
Lock Replacement across Simi Valley
Simi Valley's housing stock shapes what we replace. Many 1970s ranch homes in areas like Texas Tract still run original or well-worn Kwikset and Schlage hardware, and a move-out or lost key is a natural moment to upgrade to a sturdier grade or a rekey-friendly design. Newer developments such as Wood Ranch and Big Sky tend to have modern deadbolts, HOA-standardized hardware and a growing number of smart locks, where matching finish and programming matter as much as the lock itself.
In Santa Susana Knolls, older rustic and cabin-style homes on winding lanes sometimes have doors that are not standard, with older frames and unusual preps. Replacing a lock there can call for careful fitting rather than a drop-in swap. Homes in Bridle Path and across ZIP codes like 93063 and 93065 range widely in age, so we look at each door individually rather than assuming one size fits all.
We also work with businesses, from aluminum-storefront strip retail along Cochran Street and First Street to business parks near Easy Street and Madera Road, and shops around the Simi Valley Town Center. Whether you are near the Reagan Library, Rancho Simi Community Park, or off SR-118 or SR-23, we come to you. Call (323) 997-8867 any hour.
