A gate that will not latch, a keypad that has stopped responding, or a lock that binds every time the weather turns is more than an annoyance. In Diamond Bar, where so many homes sit on hillsides with side yards, driveways and pool areas closed off by gates, a failing gate lock can leave a property open or leave you shut out of your own yard. Crenshaw Lock Company has been serving Greater Los Angeles and Ventura County since 1987, and gate hardware is a regular part of the work.
We are fully mobile, so there is no shop to drive to. A technician comes to your gate with tools and common parts, looks at what is actually failing, and repairs it on site when repair makes sense. Often the problem is a worn latch, a misaligned strike, a corroded cylinder, a dead keypad battery or a loose mounting. Sometimes the right answer is replacement, and we will explain why before any work begins.
We work on residential side gates and driveway pedestrian gates, as well as gates at small commercial properties like the strip centers and office parks near the freeway interchange. Our owner and lead technician, David Shar, has run the company for decades, and the approach is simple: diagnose honestly, fix what needs fixing, and leave the gate secure.
How it works in Diamond Bar
- 1
Call and describe the gate
Call (323) 997-8867 any hour. Tell us what type of gate it is (wood, wrought iron, aluminum or tubular steel), what the lock looks like, and what it is doing. A keypad that is dead, a latch that sticks, and a lock that will not turn each point to different causes, so these details help us bring the right parts.
- 2
On-site inspection
The technician looks at the whole latch system rather than just the lock: hinges, gate sag, strike alignment, the latch body, the cylinder and any keypad or electronic parts. Many gate lock complaints are really alignment or wear problems, and finding the real cause avoids paying for the wrong part.

Clear recommendation
Before work starts, we explain whether the lock can be repaired, rekeyed or should be replaced, and what each option involves. If you are in a guarded community or a rental, we can also talk through what is allowed and who needs to be informed.

Repair, rekey or install
We repair or replace the latch, cylinder or keypad lock, adjust the strike, and lubricate or protect the hardware suitable for outdoor use. For smart or keypad gate locks, we set codes and test the unit. If a rekey is the right fix, existing hardware stays and old keys stop working.
- 5
Test and hand-off
We cycle the gate several times from both sides, confirm it latches under its own swing, and make sure every key or code works. You get a plain explanation of any codes, batteries and simple maintenance that will keep the lock working.

What affects the price
- The type of lock involved: a basic mechanical latch is a different job than a keypad lock or a smart gate lock with electronics.
- Whether the existing hardware can be repaired or rekeyed, or has to be replaced because of corrosion, wear or damage.
- Gate material and condition, since a sagging gate or bent frame may need adjustment before any lock will work properly.
- Parts selection, including the grade of outdoor-rated hardware and any keypad or smart features you want.
- The time of day and the urgency of the call, as after-hours and emergency visits involve different scheduling than a planned appointment.
- How many gates or locks need work in a single visit, and whether keys need to be matched across several of them.

Gate Lock Repair across Diamond Bar
Diamond Bar's terrain shapes its gate hardware. Hillside lots in Pathfinder and the Summitridge area often have side-yard and driveway gates that sit on slopes, where settling and wind can pull a gate out of alignment and make a latch miss its strike. In the Sunset Crossing area, many homes from the 1960s to 1980s have older gate latches that have been exposed to decades of sun, which dries out lubricants and wears the moving parts. A lock that binds in the afternoon heat but works in the morning is a common sign.
The Country Estates is a guard-gated enclave of large hillside custom homes, and the properties there often layer several security features: a perimeter or driveway gate with a keypad, a high-end front door lock and multi-point patio-door locks. If you are locked out or a gate keypad fails there, we can work the gate hardware and the entry locks with care for the finish. We also work with homeowners in ZIP code 91765 and 91789, from homes near Diamond Bar Blvd and Golden Springs Dr to those closer to Sycamore Canyon Park and the Diamond Bar Golf Course.
For commercial customers, we also help at strip centers and office parks near the SR-57/SR-60 interchange at Grand Avenue and around Diamond Hills Plaza, where service gates, trash enclosures and rear lots rely on dependable latches. Wherever you are in Diamond Bar, call (323) 997-8867 and we will come to you.
