A deadbolt is the single most useful upgrade you can make to an exterior door, and in Sun Valley the doors vary enormously. In one neighborhood you have modest postwar homes with a basic knob lock as the only protection. A few blocks away are 1920s stone and clinker-brick houses with original hardware, and along San Fernando Road there are warehouses and yards with steel man-doors that see heavy daily use. Each of these calls for a different approach to a deadbolt, and we treat them that way.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a fully mobile operation, so there is no storefront to visit. We bring the hardware and tools to your property, look at the door, the frame, and the strike, and install a deadbolt that actually suits how the door is used.

A deadbolt is only as strong as the door and frame around it. Part of our work is checking that the bolt throws cleanly into solid framing, that the strike plate is anchored properly, and that the door is not flexing or sagging. We explain the options plainly, including when a single cylinder makes more sense than a double cylinder, and then we do the installation.

How it works in Sun Valley

  1. 1

    Call and describe the door

    Call (323) 997-8867 at any hour. Tell us whether the door is wood, metal, or a glass-paneled entry, whether you want a new deadbolt added or an old one replaced, and whether the property is a home, shop, or warehouse.

  2. 2

    Assess the door and frame

    On arrival we inspect the door's thickness, condition, and existing bore holes, along with the jamb and strike area. This tells us whether a standard install will hold up or whether reinforcement is needed.

  3. 3

    Choose cylinder type and hardware

    We walk through single-cylinder (thumbturn inside) versus double-cylinder (key on both sides) options. Double cylinders can slow your exit in an emergency, so we discuss fit, local code considerations, and glass near the lock before you decide.

  4. 4

    Install and align

    We fit the deadbolt, cut or adjust the bore as needed, and set the strike plate with longer screws into the framing where appropriate. On older doors we work carefully to limit visible changes to the wood and finish.

  5. 5

    Test and key handoff

    We cycle the bolt repeatedly with the door open and closed, confirm it throws fully, and hand over keys. If you want it keyed to match other locks on the property, we can arrange that during the visit.

What affects the price

  • Whether you need a new deadbolt added or an existing one replaced, since adding one may involve drilling a new bore
  • The grade and style of the deadbolt itself, from standard residential hardware to heavier commercial-grade units
  • Door material and condition, including solid wood, hollow-core, steel, or older doors needing careful work
  • Frame and strike reinforcement, such as longer screws, a reinforced strike plate, or jamb repair
  • Keying needs, such as keyed-alike sets across several doors or a master system for a business
  • Number of doors and the time of day or night you need service

Why Sun Valley chooses us

  • Fully mobile service: we come to your Sun Valley door at any hour, with no storefront detour
  • Operating since 1987, so we have seen everything from aging 1920s door hardware to modern steel commercial doors
  • Owner-led by David Shar, with hands-on experience across residential and commercial work
  • We check the door and frame, not just the lock, because a strong bolt in a weak jamb protects very little
  • Sympathetic installs on historic homes, aiming to keep original doors looking as intact as possible
  • Plain explanations of single- versus double-cylinder tradeoffs, including the emergency-exit concern

Deadbolt Installation across Sun Valley

Sun Valley sits at the base of the Verdugo Mountains, and its housing mix shapes the work we do. In the Stonehurst area, 1920s stone and clinker-brick houses often still carry original door hardware. Owners there usually want better security without ruining the character of the door, so we favor careful boring, finishes that blend in, and a rekey of existing locks when it makes sense. In the postwar residential blocks around ZIP code 91352, we more often replace worn knob-only setups with a proper deadbolt and reinforced strike.

The industrial side of Sun Valley has its own needs. Along San Fernando Road and the corridor behind Hollywood Burbank Airport, warehouses, shops, and yards depend on sturdy man-doors. After staff turnover or a break-in, a commercial-grade deadbolt on the walk-in door is often the first fix, and we can pair it with rekeying so old keys stop working.

We travel the roads you use every day, including San Fernando Road, Glenoaks Boulevard, Sunland Boulevard, Vineland Avenue, I-5, and CA-170, whether you are near the Stonehurst Recreation Center, close to the LADWP Valley Generating Station smokestacks, or up toward La Tuna Canyon. Call (323) 997-8867 and we will come to you.

Deadbolt Installation in Sun Valley — FAQs

Can you install a deadbolt on a door that doesn't have one?
Yes. If the door is thick enough and in good shape, we can drill a new bore and add a deadbolt. Call (323) 997-8867 and describe the door so we can bring suitable hardware.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder has a thumbturn inside and is easier to exit quickly. Double-cylinder needs a key on both sides, which can help near glass but may slow escape in an emergency. We talk through your door and layout before installing.
Can you upgrade a deadbolt on an older Stonehurst home without damaging the door?
We work carefully on historic doors, using the existing bore where possible and choosing finishes that blend in. We can also rekey original locks when appropriate. Call (323) 997-8867 to discuss your door.
Do you install deadbolts for businesses and warehouses?
Yes. We handle man-door deadbolts for shops, warehouses, and yards along San Fernando Road and the airport corridor, and can rekey after staff changes. We do not describe roll-up or gate work here, but ask and we will advise.
Do you offer service at night or on weekends?
We are available 24/7 and fully mobile, so you can call at any hour. There is no storefront, and we come to your property.
Will a new deadbolt help if my door frame is weak?
Only partly. The frame and strike matter as much as the bolt. We inspect the jamb and can reinforce the strike area with longer screws or a stronger plate as needed.
Can the new deadbolt use the same key as my other locks?
Often yes. We can key the deadbolt to match existing locks or set up keyed-alike hardware for several doors. Ask when you call (323) 997-8867.
How is the price decided?
It depends on factors such as new install versus replacement, hardware grade, door material, frame reinforcement, keying, and timing. We explain what applies to your door before work begins.
