Rekeying is the practical answer when you cannot be sure who still holds a key to your property. We change the internal pin configuration of your existing lock so that the old keys no longer turn it, and new keys do. The lock, the finish and the look of your door stay the same. In San Dimas it is a common request after buying a home, after a tenant or contractor moves on, or when a key has gone missing.

The city has an unusual mix of properties, and that shapes the work. Ranch-style homes from the 1960s and 1970s, larger lots near San Dimas Canyon with barns and gated drives, planned-community homes in Via Verde, and small buildings along Bonita Ave in Old Town all have different hardware and different needs. A single visit might cover a front door, a back slider, a garage side door and several padlocks.

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, with no storefront to visit. We bring the tools and key blanks to you, so the job is done on your property and you can test every lock before we finish.

How it works in San Dimas

  1. 1

    Tell us what needs to be secured

    Call (323) 997-8867 and describe the property: how many exterior doors, whether there are gates, outbuildings or padlocks, and why you want the change. Knowing if this is a new purchase, a lost key or a tenant turnover helps us bring the right supplies.

  2. 2

    We come to you

    Because we are mobile and available 24/7, we travel to your home, ranch property or business. There is no shop to drive to, and no need to take your locks off the door and bring them anywhere.

  3. 3

    Inspect each lock

    We check every lock for brand, condition and whether it can be rekeyed. Most standard deadbolts and knob sets can. A worn, damaged or mismatched lock may be better replaced, and we will say so plainly rather than rekey something that will fail soon.

  4. 4

    Rekey and match the set

    We remove the cylinders, change the pinning and rebuild them. Where it makes sense, we key several locks alike so one key works the front door, the back door and the garage entry, which is handy for a household or a small shop.

  5. 5

    Cut new keys and test everything

    We cut new keys, then test each lock repeatedly with the new key and confirm the old key no longer works. You see the result before we leave.

  6. 6

    Advise on weak points

    While we are there, we point out loose strike plates, short screws or worn latches. You decide whether to address them. Nothing is added without your agreement.

Lock Rekeying across San Dimas

San Dimas feels more like a foothill town than a typical LA suburb, and the properties reflect that. In ZIP code 91773, many homes are ranch-style builds from the 1960s and 70s, often with original locks that have passed through several owners. Rekeying is a straightforward way to reset who has access without changing the look of the house.

Near San Dimas Canyon, and around Frank G. Bonelli Regional Park and Puddingstone Reservoir, lots tend to be larger, and horse-keeping is part of life. That means barns, tack rooms, outbuildings and gated drives secured with padlocks and chains. We can rekey the house and bring the outbuilding and gate locks onto a system that is easier to manage, whether that is a single key or a short, sensible set. In Via Verde, on the southern hills, homes typically have HOA-standard hardware. After a purchase, rekeying the existing locks keeps the approved appearance and removes any question about previous keys.

Downtown, the western-themed buildings along Bonita Ave are small retail and civic spaces where a former employee or a change in tenants is a common reason to rekey. We reach homes and businesses from Foothill Blvd, Arrow Hwy and San Dimas Ave, with the Foothill Freeway (I-210) and the SR-57 close by.

Lock Rekeying in San Dimas — FAQs

What does rekeying a lock actually do?
It changes the internal pins of the lock so that old keys no longer work and a new key does. The lock itself stays in your door, so the hardware and finish look the same.
Should I rekey after buying a home in Via Verde?
It is a good idea. You cannot know how many copies of the old keys exist. We rekey the existing HOA-standard locks so the look stays consistent. Call (323) 997-8867 to arrange it.
Can you rekey padlocks and gate locks on a horse property?
In many cases, yes. We can work on barn, tack room and gate padlocks near San Dimas Canyon, depending on the lock type. Some worn or weathered ones are better replaced, and we will tell you which.
Is rekeying cheaper than replacing locks?
Often it is, since you keep your existing hardware, but it depends on lock condition and quantity. We do not quote figures here because the price depends on the factors above. Call (323) 997-8867 to discuss your situation.
Can all my doors use the same key?
Usually yes, if the locks are compatible brands and in good shape. We can key them alike so one key opens the front door, back door and garage entry.
Do you offer rekeying at night or on weekends?
Yes. We are available 24/7 and fully mobile. For urgent needs, call (323) 997-8867 any time.
Do I have to be present during the rekey?
Someone authorized should be present so we can verify the property and test the locks with you. We do not work on locks without confirming you are entitled to have them changed.
Can you rekey a business lock on Bonita Ave?
Yes, we handle small retail and office locks. If a former employee or tenant had keys, rekeying is a practical step, and we can also help with lockouts.
