A deadbolt is the single most useful upgrade you can make to an exterior door. A spring latch in a worn knob lock can often be slipped with a flat tool or forced with a shoulder. A properly installed deadbolt throws a solid steel bolt into the frame and does the real work of keeping a door shut. In Valley Glen, where so many homes are 1940s and 1950s ranch and traditional houses, that upgrade is common, and it is often overdue.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business on fully mobile service. There is no storefront to visit. We are available around the clock and bring the work to your front door, back door or condo entry, so you can have a deadbolt added or replaced without rearranging your day.

Some calls are a simple swap of an old deadbolt for a new one. Others involve a door that has never had one, a bored hole that needs to be matched, or a frame that needs reinforcing so the bolt actually has something solid to bite into. We look at the door first, explain what we see, and install hardware that suits it rather than pushing a one-size-fits-all product.

How it works in Valley Glen

  1. 1

    Talk through the door and your goal

    When you call (323) 997-8867, we ask what you are trying to solve: adding a first deadbolt, replacing a worn one, matching keys to other locks, or preparing a rental for a new occupant. We ask about the door material and whether it already has a bored hole.

  2. 2

    Inspect the door and frame on site

    At your home we check the door thickness, the existing holes, the strike plate and the frame. A deadbolt is only as strong as the wood around it, so we look for cracked jambs, loose hinges and short screws that would undermine the lock.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt turns with a thumbturn inside and a key outside. A double-cylinder needs a key on both sides, which can matter for doors with glass nearby but can slow a fast exit in an emergency. We explain the tradeoffs so the choice is yours.

  4. 4

    Install and align the hardware

    We bore or adjust the holes as needed, set the bolt, mount the lock and fit the strike plate with screws long enough to reach the framing. The bolt should extend and retract smoothly without the door being lifted or pushed.

  5. 5

    Key it the way you want

    If you want the new deadbolt keyed alike with your other exterior locks, so one key works front and back, we can arrange that. For a tenant change, we can key it separately so old keys no longer work.

  6. 6

    Test everything before we leave

    We operate the lock repeatedly with the door open and closed, check the strike alignment, and hand you the keys. You should leave confident that the door locks fully and the thumbturn feels solid.

What affects the price

  • Whether you need a brand-new installation, which may require boring holes, or a replacement that uses an existing opening.
  • The grade and brand of deadbolt, since heavier-duty graded hardware costs more than basic builder-grade options.
  • Single-cylinder versus double-cylinder, and whether you want a keypad or smart deadbolt instead of a traditional key lock.
  • The condition of the door and frame, including whether the jamb needs reinforcement or the strike area needs repair.
  • How many doors are being done and whether they are keyed alike, which affects hardware and time on site.
  • Whether the visit is during regular hours or an after-hours call, since we are available 24/7.

Why Valley Glen chooses us

  • We are fully mobile, so the work happens at your door with no trip to a shop and no storefront to track down.
  • Serving Greater Los Angeles and Ventura County since 1987 means we have seen nearly every door type, including the older wood doors common on mid-century homes.
  • We check the frame and strike plate, not just the lock, because a strong bolt in a weak jamb is not real security.
  • We explain single versus double cylinder honestly, including the safety tradeoff, instead of defaulting to the more expensive option.
  • We can key deadbolts alike for homeowners or separately for landlords and tenants, depending on your situation.
  • Available 24/7, so a broken or failed deadbolt does not have to wait until morning.

Deadbolt Installation across Valley Glen

Valley Glen is a quiet residential community carved out of Van Nuys and North Hollywood, and its streets are lined with 1940s and 1950s single-family homes. Many of those houses still carry original knob locks or aging hardware on the front door. Homeowners in ZIP codes like 91401 and 91405 often call us when they are selling or just bought, wanting a graded deadbolt added and exterior locks keyed alike, sometimes with a smart deadbolt on the front door.

The Los Angeles Valley College district brings a different kind of call. Rentals and apartments near campus see regular turnover, and landlords or tenants want deadbolts replaced or rekeyed between occupants so earlier keys stop working. Condos and townhomes off Burbank Boulevard, including those in 91606, sometimes have worn knob locks that fail or leave a door hard to secure, and a new deadbolt is a straightforward fix.

We work throughout Valley Glen, from homes near the Tujunga Wash and the Great Wall of Los Angeles mural to streets near Valley Glen Community Park, and along corridors like Victory Boulevard, Oxnard Street and Coldwater Canyon Avenue. Getting around is easy with CA-170 close by, and because we are mobile and available 24/7, you can call (323) 997-8867 whenever you need a deadbolt installed.

Deadbolt Installation in Valley Glen — FAQs

Can you add a deadbolt to a door that only has a knob lock?
Yes. If the door is thick enough and in good shape, we can bore the extra hole for a deadbolt and install it with a proper strike plate. Call (323) 997-8867 and describe your door and we will tell you what to expect.
Should I choose a single-cylinder or double-cylinder deadbolt?
Most homes do well with single-cylinder, which uses a thumbturn inside for easy exit. Double-cylinder suits doors with glass nearby but needs a key on the inside too, which can slow escape in an emergency. We can walk through both for your door.
Will a new deadbolt work with my older 1950s door?
Usually, yes. Many Valley Glen homes have solid wood doors that accept standard deadbolts well. We check thickness and the existing holes first, and adjust or reinforce the area if needed.
Can all my exterior locks use the same key?
Yes, we can key new deadbolts alike with your other exterior locks so one key opens the front and back doors. This is a popular request for homeowners moving in or preparing to sell.
I rent near Los Angeles Valley College. Can the deadbolt be changed between tenants?
Yes. We can replace or rekey deadbolts so previous occupants' keys no longer work. Landlords and tenants can call (323) 997-8867 to arrange it, ideally with permission from whoever manages the property.
Do you install smart or keypad deadbolts?
Yes, we can install keypad and smart deadbolts as well as traditional key models. We can talk through which suits your door, your routine and how many people need access.
Is there a shop I can visit?
No. We are fully mobile and come to your location in Valley Glen. There is no storefront, so just call (323) 997-8867 and we will arrange the visit.
Can you come after hours if my deadbolt fails?
Yes. We are available 24/7. If a deadbolt will not lock or the key has broken, call (323) 997-8867 and we will work out a fix so your door is secure.
