Rekeying is the practical answer when you want to control who can open your doors without replacing every lockset. We change the internal pin configuration of the lock cylinder so the old keys no longer turn it, and new keys are cut to match. The hardware on your door stays put, the finish stays the same, and the keys floating around from previous owners, contractors, tenants, or an ex-roommate become useless.
In Granada Hills this comes up constantly. The Northern Valley is full of 1950s and 60s ranch tract homes that change hands regularly, and many still carry their original locksets, or a mix of whatever a past owner installed over the decades. Nobody can say how many copies of those keys exist. A rekey right after closing is one of the simplest and most affordable ways to start fresh, and we can set every exterior door to a single key so you carry one instead of four.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, with no storefront to visit, so the whole job happens at your door, whether that is a ranch home off Chatsworth St, a mid-century home in Balboa Highlands, or a foothill property with a driveway gate.
How it works in Granada Hills
- 1
Call and describe the situation
Call (323) 997-8867 and tell us what you have: how many exterior doors, whether there are deadbolts, knobs, or handle sets, and whether a gate or outbuilding lock is involved. Tell us if you just bought the home, had a break-in, or lost a key. We are available 24/7, so you can call after closing or late at night.

Inspect the existing hardware
When we arrive we look at each lock. Worn original locksets on older ranch homes sometimes rekey perfectly. Others are too corroded, loose, or damaged to rekey reliably, and we say so honestly rather than sell you work you do not need.
- 3
Remove and rekey the cylinders
We take each cylinder out, remove the old pins, and rebuild it with a new pin configuration. Done carefully, this keeps the lock's look and feel intact, which matters on restoration-minded homes.

Key everything alike if you want
If you prefer one key for the front door, back slider, garage entry, and side gate, we can match them within the limits of the hardware's keyway. You can also keep certain doors on separate keys, such as a guest house or storage area.
- 5
Test every lock and every key
Before we leave we operate each lock several times with the new keys and confirm the old keys no longer work. We also check that deadbolts throw fully into the strike, since doors on older homes shift over time.
- 6
Hand over keys and next steps
You get your new keys and a straightforward note on anything we noticed, such as a loose strike plate, a worn latch, or a gate lock that is nearing the end of its life, so you can decide what to do next.

What affects the price
- The number of cylinders to be rekeyed, since each exterior door, deadbolt, and gate lock is worked on individually.
- The brand, keyway, and condition of the existing locks, because some hardware rekeys easily and some needs extra care or parts.
- Whether you want all locks keyed alike or several separate key groups.
- How many new keys you need cut for family members, tenants, or caretakers.
- Specialty or restoration-sensitive hardware, such as mortise locks or vintage mid-century entry sets, which takes more time to handle without damaging the finish.
- Whether the visit is during regular hours or a late-night or weekend call-out.
Why Granada Hills chooses us
- We are fully mobile and serve Granada Hills at your door, so there is no shop trip and no leaving your home unsecured.
- We have been in business since 1987, so older tract-home hardware and unusual locksets are familiar territory.
- We tell you when a lock should be rekeyed and when it should be replaced, rather than defaulting to the bigger job.
- We are careful with restoration-sensitive hardware, so period entry sets on mid-century homes keep their original appearance where possible.
- Available 24/7, so a rekey after a lost key, a breakup, or a late closing does not have to wait for business hours.
- We can handle the whole property in one visit, including house doors, garage entry, and gate locks.
Lock Rekeying across Granada Hills
Granada Hills spans a lot of different housing, and rekeying needs vary with it. In Old Granada Hills, around the Chatsworth St district, many 1960s ranch homes still have their original front-door locksets. A new owner there will often want the worn original lock rekeyed and every exterior door keyed alike, which is a tidy job we handle regularly in ZIP code 91344.
Balboa Highlands is its own case. Joseph Eichler's mid-century modern tract has entry hardware that owners prefer to preserve, and a rekey is often a better fit than swapping in modern hardware that changes the look of the front door. We approach those locks gently and aim to keep the original character intact. Knollwood, with its proximity to Knollwood Country Club, has its own mix of established homes where changing keys after a sale is just as common.
On the north edge, foothill homes near O'Melveny Park and Bee Canyon deal with Santa Ana dust, dry heat, and sun that can leave locks and driveway gates sticky or stiff. We service exterior locks and gate hardware in those conditions, including addresses in ZIP code 91394. Whether you are just off Balboa Blvd, Zelzah Ave, or Devonshire St, or near the 118 or 405, call (323) 997-8867 and we will come to you.
