Rekeying is the practical answer when you can't be sure who still holds a key to your home. You may have just bought a house in Walnut, ended a tenancy, parted ways with a contractor, or simply lost track of copies over the years. A rekey changes the inside of each lock cylinder so the old keys no longer turn it, and a new key works instead. The locks stay on the door, and so does the look of your hardware.

Walnut is mostly single-family tract homes from the 1970s and 80s on generous lots, with newer custom builds and gated enclaves mixed in. Many of those homes have several entry points: a front door, a garage side door, a back slider, a side gate, and sometimes a barn or pool gate. A good rekey accounts for all of them so one key can run the whole property, rather than leaving you juggling a ring of mismatched keys.

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 visit. We work at your property, at hours that suit you, and we explain what we are doing as we go.

How it works in Walnut

1
Tell us about the property
When you call (323) 997-8867, describe how many locks you have, what kind they are, and why you are rekeying. A move-in, a lost key, and a former roommate all call for slightly different priorities, and knowing the situation helps us bring the right pinning kits and key blanks.
2
Inspect each lock on site
We check every cylinder: deadbolts, knob sets, garage entry doors, slider locks, and gate or padlock hardware. Worn, damaged, or mismatched cylinders sometimes can't be rekeyed reliably, and we will tell you plainly if one should be replaced instead.
3
Remove and re-pin the cylinders
We take each cylinder apart, remove the old pin configuration, and set new pins that match a fresh key cut. Because the work happens at your door, you can usually keep using the home throughout.
4
Key everything alike if you want
Most homeowners prefer a single key for the front door, back door, and garage entry. We can set the cylinders to match, and keep any separate locks, like a shed or gate lock, on their own key if you prefer.
5
Test every lock and every key
Before we finish, we operate each lock several times with the new keys and confirm the old keys no longer work. We also check that the bolts throw smoothly and the doors latch correctly.
6
Hand over keys and advise on next steps
You receive your new keys and we can cut extras on site. If a lock looks weak or you are considering a smart lock upgrade, we will say so honestly, but there is no pressure to add anything.

What affects the price

The number of locks and cylinders being rekeyed, since each one is disassembled and re-pinned individually.
Whether the locks are standard residential brands or higher-security or specialty cylinders that need different parts or procedures.
The condition of the hardware: worn or damaged cylinders may need replacement rather than a simple rekey.
How many keys you want cut, and whether all locks are keyed alike or kept on separate keys.
Gate, barn, or outbuilding locks, which can involve padlocks or heavier-duty hardware than a standard door.
The time of day or night you need service, given that we are available around the clock.

Why Walnut chooses us

Fully mobile service, so the work is done at your door and you never have to bring locks anywhere.
Operating since 1987, with owner and lead technician David Shar guiding the work and standards.

We test every lock and confirm old keys are dead before we leave, so you know the job is complete.

Lock Rekeying across Walnut

Walnut sits between the San Jose Hills and the Puente Hills, and its housing reflects that. In Snow Creek, the gated community, homes often combine traditional keyed deadbolts with electronic or smart locks and gate-controlled access. A rekey there is a good way to reset the physical side of your security after buying a home, while we keep in mind that access codes and gate credentials are handled separately. In Walnut Heights, larger lots and hillside properties often add side gates, pool gates, and sometimes barn or driveway gate hardware that should be rekeyed along with the house.

Many people call us after closing on a home in ZIP 91789 or ZIP 91788, because previous owners, agents, and contractors may still hold working keys. Rekeying every exterior lock on move-in day is a simple, affordable-in-effort way to know exactly who has access. Near the Mt. San Antonio College area, we also hear from landlords and homeowners with rental rooms who want to change keys between tenants without replacing hardware each time.

We reach Walnut homes by way of SR-60 and SR-57, then Grand Ave, Valley Blvd, Lemon Ave, Nogales St, Amar Rd, or Pierre Rd. Whether your home is near Suzanne Park, Creekside Park, or tucked into a quiet hillside street, call (323) 997-8867 and we will come to you.

Lock Rekeying in Walnut — FAQs

What is the difference between rekeying and replacing a lock in Walnut?

Rekeying changes the internal pins of your existing lock so a new key works and old keys don't. Replacing swaps the whole lock. If your hardware is in good shape, rekeying is usually the simpler route. Call (323) 997-8867 and we can help you decide.

Should I rekey after buying a home in Walnut?

Yes, it is a smart first step. You can't know how many copies of the old keys exist, whether with prior owners, agents, neighbors, or contractors. Rekeying every exterior lock gives you a clean start.

Can you rekey locks at a Snow Creek gated-community home?

Yes. We rekey the physical door locks at the property. Gate access, codes, and community credentials are managed separately by the association, so those would need to be reset through them.

Can you rekey smart locks?

Many smart locks have a conventional keyed cylinder that can be rekeyed, but the electronic codes and app access are separate and should be reset through the lock's own settings. We can look at your specific model on site.

Can all my locks work with one key?

Usually, yes. We can key your front door, back door, and garage entry alike so one key operates them all. Specialty or high-security locks may need different handling, and we will explain what is possible.

Do you rekey gate and barn locks on equestrian properties?

We can often rekey gate and barn lock hardware, depending on the type of lock. Some padlocks and heavy-duty latches are better replaced. We will look at the hardware and tell you which makes sense.

Do I need to be home during a rekey?

Someone should be present, or you should arrange access, since we need to reach every lock and hand over new keys. Call (323) 997-8867 to work out the details.

Do you offer rekeying late at night or on weekends?

Yes, we are available 24/7 and fully mobile, so we come to your Walnut property whenever you need a rekey, including nights, weekends, and holidays.
