A lock does not last forever. In a city like La Cañada Flintridge, where many homes were built in the 1950s through the 1970s, it is common to find original knobs, tired deadbolts and sticking latches still guarding the front door. Brass wears, springs weaken, and keys that have been copied many times stop turning smoothly. Replacement is often the right answer when a lock is failing, when it has been damaged in a break-in attempt, or when you simply want better hardware than the builder installed.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around being fully mobile. There is no storefront to visit. We bring the tools and hardware to your property, whether that is a mid-century ranch near Foothill Boulevard or a gated estate on the slopes above Flintridge.
Replacement is not always the same as rekeying, and we will tell you honestly which one fits. If your hardware is sound and you only need new keys, rekeying may be enough. If the lock is worn, outdated, damaged, or does not meet the security level you want, we replace it. Many La Cañada Flintridge homeowners also choose to move to high-security deadbolts or smart-lock systems at the same visit, and we can set up matching keys across the house, garage and gates.
How it works in La Cañada Flintridge
- 1
Call and describe what you have
Call (323) 997-8867 any hour. Tell us which doors or gates need attention, what the current locks do wrong, and whether you want standard keyed hardware, a high-security deadbolt or a smart lock. This helps us bring the right parts.
- 2
We come to your property
Because we are fully mobile, a technician drives to your home. On a hillside lot with a long driveway or a gated entry, tell us how to get in so we can reach every door that needs work.
- 3
Inspect the door and existing hardware
We check the lock, strike plate, bore holes, door thickness and how the door sits in the frame. Sometimes a sticking lock is really a door alignment issue, and we will say so before selling you new hardware.
- 4
Remove the old lock and install the new one
We take out the worn or damaged hardware and fit the new lock cleanly, reinforcing the strike area where it makes sense. Deadbolts, handle sets, and gate or garage locks are installed to line up smoothly.
- 5
Key coordination and testing
If you want one key for the front door, side gate and garage, we set the locks up to work together. We test every lock from both sides, with the door open and closed, before we finish.
- 6
Walkthrough and key handoff
We show you how the new hardware works, including any smart-lock features and how to manage codes or extra keys, then hand over your keys and leave the work area tidy.

What affects the price
- The type of lock chosen: a standard keyed deadbolt, a high-security cylinder and a smart lock differ widely in hardware cost.
- How many doors and gates need replacement in one visit, including front, side, patio, garage entry and pedestrian gates.
- Door and frame condition, since a damaged strike area, misaligned door or unusual bore may require extra work.
- Specialty or estate hardware, such as decorative handle sets, mortise locks or gate-specific lock bodies, which can be harder to source.
- Whether you need locks keyed alike across several doors, which takes added setup time.
- The time of day and urgency of the call, since after-hours and emergency visits differ from scheduled daytime work.
Why La Cañada Flintridge chooses us
- Fully mobile service: we work at your door, not from a shop, so you never have to leave a vulnerable property to get new locks.
- Open 24/7, which matters if a break-in damages a lock at night and you need the door secured right away.
- Serving the region since 1987 under owner and lead technician David Shar, with long experience across older ranch homes and newer custom builds.
- Honest recommendations on replacing versus rekeying, so you only pay for new hardware when it is actually needed.
- Comfortable with both traditional high-security deadbolts and smart-lock setups, and with coordinating house, gate and garage keying.
- No invented promises: we talk through factors that affect cost with you before work begins.
Lock Replacement across La Cañada Flintridge
La Cañada Flintridge is an affluent, hillside city split by the 210 Freeway, and its housing shapes the work we do. In Flintridge, you will find many 1950s to 1970s ranch and mid-century homes with original hardware that is now decades old, alongside newer custom homes and gated estates on the slopes toward the Angeles forest. Around Alta Canyada, long driveways, perimeter gates and pedestrian gates mean a lock project often covers more than the front door. In the Sagebrush area, we see the same mix of established homes and owners who want upgraded security.
Typical jobs here include installing a high-security deadbolt or smart-lock package on a gated hillside property and replacing or rekeying the gate hardware to match. Another common request comes from a new owner, such as a JPL engineer who buys a mid-century ranch near Foothill Boulevard and wants the house, side gate and garage consolidated onto a single key. Homes in ZIP codes 91011 and 91012 often have several entry points, so we plan the visit around all of them.
We also help people who are simply passing through. Visitors to Descanso Gardens or Memorial Park occasionally call us for a car lockout or key-fob reprogramming. Whether you are near Flintridge Preparatory School, off Verdugo Blvd, along Angeles Crest Hwy or close to the I-210 and SR-2 interchange, call (323) 997-8867 and we will come to you.
