Rekeying is the quickest way to take back control of who can open your doors. Instead of replacing hardware, we change the internal pin configuration of the lock cylinder so that a new key works and every previously cut key becomes useless. The locks you already chose, the finish, the handle style, the deadbolt, all stay on the door. In Tarzana, where homes range from 1950s ranch houses to hillside estates, that matters, because the hardware is often something you want to keep.

People call us for rekeying for a handful of common reasons: they just bought a home and have no idea how many copies of the keys are out there, a housekeeper or contractor has left, a tenant moved out, or a business has had staff turnover. Rekeying answers all of these without the cost and disruption of a full lock replacement. And because the work is done where the door is, you don't have to take anything apart and drive it somewhere.

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. We bring the tools and key-cutting capability to your door in Tarzana, at any hour, so the job gets done on your schedule rather than ours.

How it works in Tarzana

  1. 1

    Tell us what you need to secure

    Call (323) 997-8867 and describe the property: how many doors, whether there are deadbolts, mortise locks, smart locks, gates or garage entries, and why you want to rekey. This helps us bring the right parts and plan the visit.

  2. 2

    We inspect each lock on site

    Before rekeying, we check that every cylinder is in good working order. A worn, sticky or damaged lock is better repaired or replaced than rekeyed, and we will tell you plainly which is which, such as an older mortise lock that has begun to seize.

  3. 3

    Cylinders are rekeyed to a new key

    We remove the cylinders, replace the internal pins to match a new key cut, and reassemble. Every old key, including copies you don't know about, stops working. Where it makes sense, we key several doors alike so you carry one key.

  4. 4

    Testing every door

    We test each rekeyed lock with the new key several times and confirm the old key no longer turns it. Deadbolts, handlesets, side doors and any other entries are checked before we leave.

  5. 5

    Extra keys and credential cleanup

    We cut the number of keys you need. For homes with smart locks or gate intercoms, we also discuss changing codes and removing old user credentials, since a new physical key does not cancel an old keypad code.

What affects the price

  • How many cylinders need rekeying, since each lock is worked on individually
  • The type of lock: standard deadbolts, mortise locks and high-security cylinders each take different amounts of work and parts
  • Whether the locks need to be keyed alike or set up under a master-key system for an office suite
  • The number of new keys you want cut, and whether they are restricted or high-security key blanks
  • Whether any locks are worn or damaged and need repair or replacement rather than a simple rekey
  • Time of day and urgency, since we work around the clock and after-hours calls are handled differently than scheduled daytime visits

Lock Rekeying across Tarzana

Tarzana's housing splits along Ventura Blvd, and the rekeying work does too. North of the Boulevard on the Tarzana flats, many 1950s ranch homes and apartments still carry mixed builder hardware, with a different brand of lock on the front door, back door and side gate. A rekey there often means bringing everything onto one key. Those older doors also sometimes hide tired hardware. A seized front-door mortise lock on a ranch home, for example, may call for extraction and a rebuild rather than a simple pin change.

South of the Boulevard, the Santa Monica Mountains hillside and the area around El Caballero hold custom homes and gated estates. Here, rekeying is often about people turnover: a housekeeper, nanny or contractor has left and the owners want every key they ever held to stop working. These properties frequently combine high-security cylinders with smart locks and a driveway gate intercom, so we look at the keyed locks and talk through changing the electronic codes too. If you're in 91356 off Mulholland Dr or the streets running up from Reseda Blvd and Tampa Ave, we come to you.

Along Ventura Blvd, the medical and commercial corridor near Providence Cedars-Sinai Tarzana Medical Center is full of professional suites where staffing changes are routine. We rekey suite doors and set up master-key systems so management can open everything while individual staff open only their own areas. Whether your property is in 91356 or 91357, near Wilbur Ave, Corbin Ave, Lindley Ave or the US-101, call (323) 997-8867 any time.

Lock Rekeying in Tarzana — FAQs

What does rekeying a lock actually do?
Rekeying changes the internal pins of the lock cylinder so that a new key operates it and the old keys no longer do. The lock itself stays on the door. If you want to schedule a rekey in Tarzana, call (323) 997-8867.
Should I rekey after buying a home in Tarzana?
Yes, it is a sensible first step. You can't know how many copies of the old keys exist among previous owners, tenants, agents and workers. Rekeying makes sure only the keys you hold will work.
Is rekeying better than replacing the locks?
If the locks are in good condition and you like them, rekeying is usually the more economical choice. If a lock is worn, damaged or low quality, replacement may be wiser. We will give you an honest recommendation after inspecting it.
Can you rekey the locks at my office on Ventura Blvd?
Yes. We rekey suite doors and can set up master-key arrangements so management and staff have different levels of access, which is useful after staffing changes. Call (323) 997-8867 to discuss your suite.
Does rekeying change my smart lock or gate codes?
A physical rekey does not change electronic codes. For smart locks and gate intercoms, such as those at hillside estates, codes and user credentials need to be changed separately. We can talk you through that while we are there.
Can all the locks at my house use the same key?
Usually yes. Many Tarzana homes have a mix of brands on different doors, and we can often key them alike so one key operates every entry, as long as the lock types are compatible.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your location in Tarzana instead of operating a storefront.
Are you available outside normal business hours?
We are available 24/7. If you've lost keys, had a break-in, or need locks secured after hours, call (323) 997-8867 any time.
