Locks wear out quietly. A deadbolt that sticks in the morning, a key that needs jiggling, or a latch that no longer lines up with the strike plate are all signs the hardware is near the end of its life. In Chatsworth, where many homes date from the 1950s through the 1970s, original or decades-old entry hardware is common, and replacing it is often the simplest way to restore both security and everyday convenience.

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 bring the work to your front door, your barn gate or your warehouse bay, whichever needs attention, at any hour of the day or night.

Lock replacement is different from rekeying. Rekeying changes the internal pins so old keys stop working while the hardware stays. Replacement swaps the hardware itself, which makes sense when a lock is damaged, corroded, outdated, loose, or simply not strong enough for what it protects. We will tell you honestly which one fits your situation, because sometimes cleaning or rekeying is the better answer.

How it works in Chatsworth

  1. 1

    Tell us what you have and what is wrong

    Call (323) 997-8867 and describe the door or gate, the type of lock, and the problem: seized, broken, lost keys, a tenant change, or hardware you just want upgraded. This helps us bring the right parts.

  2. 2

    Inspect the lock, door and surroundings

    On site, we check the lock, the door edge, the bore holes, the strike plate and the frame. A lock that fails is sometimes a symptom of a door that has shifted, and we point that out before we start.

  3. 3

    Recommend repair, rekey or replacement

    If cleaning, re-pinning or rekeying will do the job, we say so. If the hardware is worn, damaged or too weak for the location, we explain the replacement options and let you choose.

  4. 4

    Remove the old hardware and install the new

    We take out the old lock and fit the new deadbolt, knob, lever, gate lock or padlock, making sure it sits square, the bolt throws fully and the strike plate is properly secured.

  5. 5

    Cut and test the keys

    We set up new keys, or key several locks alike if you want one key for a house, a barn and a gate. Every lock is tested repeatedly from both sides before we finish.

  6. 6

    Walk through and hand over

    We show you how the new hardware works, hand over all keys, and answer questions about upkeep so the lock holds up against dust and heat.

What affects the price

  • The type of hardware: a basic residential deadbolt differs a lot from a high-security cylinder, a commercial-grade lock or a heavy-duty gate lock.
  • How many locks are involved, and whether you want them keyed alike or set up under a master key system.
  • Condition of the door and frame, since a worn bore, misaligned strike or damaged edge may need extra work for the new lock to fit correctly.
  • Type of lock being replaced, such as an entry deadbolt, roll-up-door hardware, a barn padlock or a driveway gate lock, each calling for different parts and labor.
  • Time of day and location, because after-hours service and hard-to-reach properties can affect the final quote.
  • Brand and security rating you choose, including features like pick or drill resistance and restricted keyways.

  • In business since 1987, with owner and lead technician David Shar involved in the work.

  • We test every lock before leaving and show you how to care for it.

Lock Replacement across Chatsworth

Chatsworth sits in the northwest corner of the San Fernando Valley against the Santa Susana Mountains, and that setting shapes how locks age. In the Indian Hills and Santa Susana Pass area, hillside homes and semi-rural lots deal with heat, dust and Santa Ana grit that can gum up exterior deadbolts until the key barely turns. Near Stoney Point Park, a seized deadbolt can often be cleaned or re-pinned, but when the internals are corroded or worn, a new lock is the more reliable fix. Many ranch tract homes in ZIP code 91311 still have their original entry hardware, and replacing it is an easy way to improve both security and everyday ease of use.

The equestrian horsekeeping district brings its own needs. Barns, tack rooms and gated driveways rely on padlocks and gate locks that sit outside year-round. If you are locked out of a tack room near Santa Susana Pass Road, or you want a new barn padlock and driveway gate lock on the same key, we can replace them in one visit and match the hardware to the weather exposure.

The industrial and business district around Canoga Avenue, Prairie Street and Lassen Street, much of it in ZIP code 91313, has plenty of warehouses and self-storage buildings. When a lease changes hands, tenants often need roll-up-door padlocks and commercial deadbolts replaced and keyed to a single master. We work from Topanga Canyon Boulevard to Devonshire Street and out toward the 118, at any hour, with no storefront needed.

Lock Replacement in Chatsworth — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins so old keys no longer work, while keeping the same lock body. Replacement installs new hardware. Rekeying suits locks in good shape; replacement suits worn, damaged or underbuilt locks. Call (323) 997-8867 and we will help you choose.
My deadbolt is stiff from dust and heat. Do I need a new one?
Not always. Dust and grit are common in Chatsworth's hillside areas, and a lock can sometimes be cleaned and re-pinned. If the cylinder is corroded or worn, replacement is the better long-term fix. We check on site and give you an honest recommendation.
Can you replace barn and driveway gate locks on horse properties?
Yes. We replace tack-room and barn padlocks and driveway gate locks, and we can key them alike so one key works for several. Hardware is chosen with outdoor exposure in mind.
Can you replace locks on a warehouse after a lease change?
Yes. We can replace roll-up-door padlocks and commercial deadbolts and key them to a single master system. Having the lease details handy helps us plan the job.
Do you offer 24/7 lock replacement in Chatsworth?
Yes. We are available around the clock and fully mobile, so we come to your home, property or business. Call (323) 997-8867 any time, including nights, weekends and holidays.
How much does lock replacement cost?
It depends on the hardware, the number of locks, the condition of the door and frame, and the time of day. We explain these factors and give you a clear quote before we start, so you know what to expect.
Do I have to visit your shop to pick out new locks?
No. We are mobile only and have no storefront. We bring hardware options to you and install the lock you choose on the spot.
Can I get all my locks keyed alike?
Usually, yes. We can set up a house, a garage, a barn and a gate on the same key, or build a master key system for a business. Call (323) 997-8867 to discuss what you have.
