Locks do not last forever. In Granada Hills, where so many homes were built in the 1950s and 1960s, it is common to find the original front-door lockset still in service, with a key that sticks, a latch that no longer catches cleanly, or a finish worn through to bare metal. Replacing that hardware is often the simplest way to make a home feel secure again, especially after a move, a lost key, or a break-in attempt.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around coming to the customer. We are fully mobile, so there is no shop to drive to. We bring the tools and hardware options to your door, whether that is a ranch home off Devonshire St, a hillside property near Bee Canyon, or a mid-century home in Balboa Highlands.

Lock replacement is not always the right answer, and we will say so. Sometimes a worn lock can be rekeyed or repaired for less trouble. Other times, replacement is the better call because the mechanism is failing, the hardware does not suit the door, or you want a different level of security. We look at what you have, explain the options plainly, and let you decide.

How it works in Granada Hills

  1. 1

    Call and describe the situation

    Reach us at (323) 997-8867 any hour. Tell us which doors are involved, what the current locks are doing, and whether you are dealing with a lockout, a move-in, or planned upgrade. That helps us bring the right hardware.

  2. 2

    On-site assessment of doors and hardware

    We come to your property and inspect each lock, the door edge, the strike plate, and the frame. Older ranch doors sometimes have drifted bores or worn strikes that affect how a new lock performs, so we check before we install.

  3. 3

    Choose the replacement hardware

    We walk through deadbolts, knob and lever sets, and mortise options. You decide on function, finish, and whether you want multiple doors keyed alike so one key covers the front, back, and side entries.

  4. 4

    Remove the old lock and install the new one

    We take out the worn hardware and fit the new lock, adjusting the latch, bolt, and strike so it throws smoothly without forcing. Where a door has been drilled or damaged, we address that so the new lock sits solidly.

  5. 5

    Test and hand over the keys

    Every lock is tested with the door open and closed, from inside and out. We hand over your new keys and confirm any old keys no longer work, so you know exactly who has access.

  6. 6

    Optional follow-up on related hardware

    If a gate lock, garage side door, or patio slider also needs attention, we can look at those during the same visit and tell you what is worth fixing versus replacing.

What affects the price

  • The number of locks being replaced, since a single deadbolt is a different job than every exterior door on a property.
  • The type and grade of hardware you choose, from standard residential sets to higher-security deadbolts or specialty mortise locks.
  • Whether doors are keyed alike, which adds cutting and setup work but simplifies daily life.
  • The condition of the door and frame, because a worn bore, damaged strike, or warped door may need extra work for the new lock to function properly.
  • Specialty or period hardware, such as restoration-sensitive entry sets, which can involve sourcing and careful fitting.
  • The time of day and the location of the property, since after-hours calls and hillside or gated access can affect the scope of the visit.

Why Granada Hills chooses us

  • Fully mobile service. Everything happens at your door, and there is no storefront to visit.
  • Available 24/7, so a failed lock or an urgent security concern does not have to wait until morning.
  • In business since 1987, with owner and lead tech David Shar leading the work.
  • We tell you when rekeying or repair is the smarter option rather than defaulting to a full replacement.
  • Familiarity with the housing in Granada Hills, from original 1950s-60s ranch hardware to mid-century entry sets where preserving the look matters.
  • We test every installation and explain what we did, so you are not left guessing about your own door.

Lock Replacement across Granada Hills

Granada Hills is a Northern Valley community with a mix of housing that shapes how lock replacement actually goes. In Old Granada Hills, around the Chatsworth St district, many ranch tract homes still carry their original 1960s front-door locksets. A new owner there will often want that worn hardware replaced and every exterior door keyed alike, so one key works throughout and no former occupant's key still opens anything. Homes in ZIP code 91344 are a good example of this, with older doors that benefit from a quick check of the bore and strike before new hardware goes in.

Balboa Highlands is different. This gated Joseph Eichler tract of mid-century modern homes has entry hardware that is part of the architecture, and owners often care about keeping a period-appropriate look. Where possible, we favor restoration or carefully chosen replacement that respects the original character rather than swapping in something that clashes with the home. Knollwood, with its proximity to Knollwood Country Club, has its own mix of established residences where updated deadbolts and consistent keying are common requests.

On the north edge, foothill and equestrian properties near O'Melveny Park and Bee Canyon deal with Santa Ana dust, heat, and wide-open driveways. Dust and temperature swings can make exterior locks and driveway gate hardware stick or wear faster, and replacing a tired lock can be the right fix. In the northern parts of ZIP code 91394 and around Balboa Blvd, Zelzah Ave, and Hayvenhurst Ave, we service homes of every age. Call (323) 997-8867 and we will come to you.

Lock Replacement in Granada Hills — FAQs

Do you offer lock replacement in Granada Hills at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile. Call (323) 997-8867 at any hour and we will talk through what you need.
Should I replace my lock or just rekey it?
It depends on the condition of the hardware. If the lock works smoothly and you only want new keys, rekeying is often enough. If the mechanism is worn, damaged, or no longer suits your door, replacement makes more sense. We will tell you honestly which fits.
My 1960s ranch home still has its original front-door lock. Is it worth replacing?
Often, yes. Original locksets can be worn internally even if they look fine, and you may not know how many keys exist. Replacing the lock and keying exterior doors alike gives you a clean, known starting point.
Can you replace locks on an Eichler home without ruining the look?
We take period character seriously. For homes in Balboa Highlands, we can discuss restoring existing hardware or choosing replacements that suit the mid-century style. Call (323) 997-8867 to describe your entry hardware.
Can you key all my exterior doors the same?
Yes. We can set new locks to work with a single key across the front, back, and side doors, as long as the hardware you choose supports it.
Do you work on driveway gates and foothill property locks?
We can look at exterior locks and gate hardware on properties near O'Melveny Park and Bee Canyon. Dust and heat can make them stick, and we will assess whether service or replacement is the better route.
Will you come to my home, or do I need to visit a shop?
We come to you. Crenshaw Lock Company is mobile only, with no storefront, so all work is done at your property.
How do I know what the replacement will cost?
Cost depends on the number of locks, the hardware you select, door condition, and any specialty work. We explain the options on site before starting. You can also call (323) 997-8867 to discuss your project.
