Locks wear out quietly. A deadbolt that sticks in the cold morning air, a key that has to be jiggled, a handleset that spins loose in the door: these are the usual signs that a lock is near the end of its life. In Rolling Hills Estates, where many homes date from the 1960s and 70s, it is common to find original hardware still doing duty decades later, along with a drawer full of keys nobody can account for.
Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while the hardware stays. Replacement swaps the whole lock or set of locks for new hardware. It makes sense when the lock is physically worn, damaged after a break-in attempt, outdated, mismatched across doors, or simply not the security grade you want protecting your family or business.
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. We have no storefront to visit. We bring the tools and hardware to you, whether that is a split-level home off Silver Spur Road, a horse property in Dapplegray, or an aluminum-frame glass door in the Peninsula Center. We are available around the clock, and we will talk through your options before any work begins.
How it works in Rolling Hills Estates
- 1
Tell us what is going on
Call (323) 997-8867 and describe the door, the lock you have now and why you want to replace it. Worn hardware, a lost key, a recent move or a break-in attempt each point toward different solutions, so the conversation helps us bring the right parts.
- 2
Look at the door and existing hardware
On arrival we inspect the lock, strike plate, latch and door edge. Many ranch-style homes have older bore holes and thin strike plates, and storefront doors may use mortise cylinders or deadlatches. We check that new hardware will fit properly and that the door itself is sound.
- 3
Choose the hardware together
We explain the options in plain terms: deadbolt grades, keyed-alike sets so one key works several doors, handlesets, lever styles for accessibility, and finishes that match what you have. You decide what fits your household or business and your comfort level.

Remove the old lock and install the new one
We take out the worn hardware, correct any alignment problems, reinforce the strike area where it is helpful, and install the new lock so the bolt throws smoothly and fully into the frame.
- 5
Test, cut keys and hand everything over
We run the lock repeatedly with the door open and closed, confirm every key works, and show you how to operate any special features. You leave with working keys and a door that locks the way it should.

Lock Replacement across Rolling Hills Estates
Rolling Hills Estates has a distinctive mix of housing, and lock needs vary with it. In Dapplegray and other equestrian-zoned areas, properties often include a main house plus barns, tack rooms and side gates, all with their own locks. Replacing worn hardware and keying everything alike makes daily life simpler, especially after a tenant move-out or a change in who has access. In Chandler Ranch and Georgeff Canyon, many 1960s and 70s ranch and split-level homes still carry original locks that are ready for an upgrade.
Near Silver Spur Road, condos and townhomes bring their own questions, from shared-entry rules to matching existing finishes. If you live in ZIP code 90274 or 90275, we can come to you at any hour, whether you are off Hawthorne Boulevard, Palos Verdes Drive North or Crenshaw Boulevard.
Businesses around Peninsula Center and the Promenade on the Peninsula on Deep Valley Drive often have glass-and-aluminum entries with narrow stiles that need specific hardware, such as Adams Rite deadlatches or mortise cylinders. We can replace those locks without a storefront trip, since we bring the work to the door. Whether you are near Ernie Howlett Park or by the bridle trails, call (323) 997-8867.
