A deadbolt is one of the simplest upgrades you can make to a door, and also one of the easiest to get wrong. A good bolt in a poorly bored door, a short strike screw into soft jamb wood, or a cylinder that does not match the door's thickness can leave you with a lock that looks strong and performs poorly. Our work in North Hills is about getting those details right on the actual door in front of us.

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 shop to visit. We come to your home, apartment, or small business with hardware and tools on board, and we are available around the clock.

North Hills has two quite different kinds of doors. The 1950s and 60s tract homes in the west have solid-core or older wood entries and often a security screen door in front. The 1960s and 70s dingbats and garden apartments in the east have a lot of unit doors, tenant turnover, and landlords who want consistent hardware. Either way, we fit the deadbolt to the door and the way you live with it.

How it works in North Hills

  1. 1

    Talk through the door and your goal

    When you call (323) 997-8867, we ask whether this is a new deadbolt or a replacement, what the door is made of, and whether you want keyed access on both sides. That helps us arrive with suitable hardware.

  2. 2

    Inspect the door, frame, and strike area

    We check the door's thickness, its condition, the existing bore holes, and how solid the jamb is. A bolt is only as strong as the wood or metal it throws into, so we look for splits, loose hinges, and worn strikes.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, which can suit doors with nearby glass but needs thought about emergency exit. We explain the tradeoffs so you can decide.

  4. 4

    Install and reinforce

    We bore or adjust the door as needed, set the bolt, and fit the strike. Where the jamb is weak, we use longer screws that reach the framing so the strike resists force better.

  5. 5

    Test, key, and hand over

    We cycle the bolt several times with the door open and closed, check alignment, and make sure the keys work smoothly. We can key the new lock to match other locks when the hardware allows it.

What affects the price

  • Whether you are adding a new deadbolt (which may need drilling) or replacing an existing one with the bores already in place
  • Single-cylinder versus double-cylinder hardware, and the grade and brand of the deadbolt you choose
  • Door material and condition, since solid wood, hollow-core, metal, and aluminum-frame doors each need different handling
  • Extra reinforcement such as longer strike screws, a new strike plate, or repairs to a worn bore or jamb
  • How many doors are being done in one visit, which is common with apartment units
  • Keying needs, such as matching several locks to one key or rekeying alongside the installation
  • Time of day and urgency, since we work 24/7 and after-hours calls differ from scheduled daytime visits

Why North Hills chooses us

  • Fully mobile service: the work happens at your door, and there is no storefront to visit
  • In business since 1987, with owner David Shar leading the work
  • Hardware choices explained plainly, including when a double-cylinder is a poor fit

  • Available 24/7, including when a break-in attempt leaves you needing a lock fixed right away

Deadbolt Installation across North Hills

North Hills, in ZIP code 91343, grew from the old Mission Acres agricultural tract into postwar suburbia, and the housing shows it. In North Hills West, many homes are 1950s and 60s single-family tract houses, often with original wood entry doors and a security screen door out front. Over decades those doors get repainted, rehung, and re-bored, so we often find a deadbolt sitting in a tired hole or a strike held by short screws. A new deadbolt with a properly reinforced strike is a practical fix.

North Hills East is denser, with many 1960s and 70s dingbats and garden apartments, and tenant turnover is higher. Landlords and property managers there often ask us to fit consistent deadbolts across several units, or to pair new bolts with rekeying so previous tenants' keys no longer work. We can handle a run of doors in one visit.

We serve the whole area, from homes near North Hills Community Park and the Sepulveda Basin Recreation Area to apartments off Roscoe Boulevard, Nordhoff Street, and Devonshire Street, and residents near Sepulveda Boulevard and the I-405. Wherever you are, we come to you, any hour.

Deadbolt Installation in North Hills — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door is thick enough and in good shape, we can drill the needed holes and fit a new deadbolt. Call (323) 997-8867 and describe the door so we can plan the right hardware.
Should I choose a single-cylinder or double-cylinder deadbolt?
Single-cylinder is the usual choice for entry doors because a thumbturn inside lets you leave quickly. Double-cylinder can make sense near glass, but it needs a key to exit, which can be a safety concern. We talk through your situation before installing.
Do you work on older tract-home doors in North Hills West?
Yes. Many 1950s and 60s doors have older bores or worn jambs. We inspect the door and frame and reinforce the strike area where needed so the new bolt holds up.
Can you install deadbolts in several apartment units at once?
Yes. Property managers in North Hills East often have us do multiple units, sometimes with matching keys or rekeying. Call (323) 997-8867 to discuss how many doors you have.
Will a deadbolt work with my security screen door?
The deadbolt goes on the main entry door, while the screen door has its own latch. If the screen door lock is worn, we can often look at it during the same visit.
Can you rekey the new deadbolt to match my other locks?
In many cases yes, depending on the brand and keyway of your existing hardware. Tell us what you have when you call and we will confirm what is possible.
Do I need to come to a shop?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your North Hills address.
Are you available at night or on weekends?
Yes, we are available 24/7. If a door was damaged or you feel unsafe, call (323) 997-8867 any time.
