A deadbolt is one of the least expensive ways to make a door harder to defeat, but only when the hardware is sound and the installation is right. A strong bolt screwed into a thin strip of old door frame can still give way with one good kick. In Compton, where so many homes were built in the 1940s and 1950s and many still carry their original or decades-old locks, a proper installation often means looking at the whole door, not just the lock.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our work is fully mobile. There is no storefront to visit. We bring the tools and a range of deadbolt hardware to your home or business, assess the door on site, and install the lock there. Owner and lead technician David Shar built the company on practical, honest door-security work, and that approach carries into every deadbolt job.

Whether you have no deadbolt at all, a worn one that sticks, or a lock you want to upgrade after a break-in or a move, we can help. We are available 24/7, so urgent situations, such as a door that will not secure after a break-in attempt, do not have to wait for business hours.

How it works in Compton

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you have: an exterior wood door, a metal door, a security screen, or a gate. Tell us whether you want to add a new deadbolt or replace an existing one, and whether you prefer single or double cylinder. That helps us bring suitable hardware.

  2. 2

    On-site door assessment

    We come to you and look at the door itself: thickness, material, condition of the edge, and the state of the frame and strike area. Older tract-home and bungalow doors sometimes have worn bores or soft, split wood, and we point those out before drilling anything.

  3. 3

    Choose the right deadbolt

    We explain the difference between single-cylinder (thumb turn inside) and double-cylinder (key on both sides) deadbolts, and between hardware grades. A double-cylinder lock can make sense with glass near the door, but it has fire-egress tradeoffs, so we talk through them honestly rather than just selling the more expensive option.

  4. 4

    Install and align

    We fit the bolt, bore or reuse the existing hole where appropriate, and install the strike plate. Alignment matters: a bolt that rubs or does not fully extend is weaker and wears out sooner, so we check it carefully.

  5. 5

    Reinforce the frame

    A deadbolt is only as strong as what it bolts into. Where the frame is weak, we can use a reinforced strike plate with longer screws that reach the framing behind the jamb, so the door resists forced entry.

  6. 6

    Test and hand over keys

    We cycle the lock repeatedly with the door open and closed, confirm smooth operation, and hand over keys. If you want several doors on the same key, we can talk through keying options during the visit.

What affects the price

  • Whether you are adding a new deadbolt to a door with no existing bore or replacing one that is already there
  • The lock grade and brand you choose, from basic residential hardware up to higher-security Grade 1 deadbolts
  • Single-cylinder versus double-cylinder, and any special keying such as keyed-alike across multiple doors
  • The condition of the door and frame, including whether the edge needs repair or a reinforced strike and longer screws are needed
  • The number of doors or gates being done in one visit, such as a front door, back door, and garage entry
  • Time of day, since after-hours and urgent service differ from a scheduled daytime visit

Why Compton chooses us

  • Fully mobile service: we install at your door in Compton and there is no shop to drive to
  • In business since 1987, with owner David Shar leading the work
  • Available 24/7, including evenings and weekends, for urgent security fixes
  • We assess the door and frame first instead of just selling a lock, which matters on older post-war and bungalow doors
  • We explain single versus double cylinder tradeoffs honestly, including egress concerns
  • Frame reinforcement is part of the conversation, not an afterthought, so the new bolt actually adds security

Deadbolt Installation across Compton

Compton has a wide mix of housing, and deadbolt needs shift from one part of the city to the next. In the 1940s and 1950s tract neighborhoods that make up much of the city, including areas around Leland and Sunny Cove, original doors and aging deadbolts are common. A typical job is a homeowner upgrading to a Grade 1 deadbolt, often paired with a reinforced strike plate, sometimes after a break-in and sometimes simply for peace of mind.

Near Downtown Compton, the 1920s bungalows can have older doors and narrow frames that need extra care during installation. In Richland Farms, the one-acre lots with ranch houses, barns, and outbuildings often mean more than one door to secure: the main house, a side entry, a workshop, or a tack room. We can talk through a consistent set of locks across those entries. Homes in ZIP codes 90220, 90221, and 90222 all fall within our service area.

We get to Compton from the I-710, I-105, and SR-91 corridors and along streets like Alameda St, Long Beach Blvd, Compton Blvd, Rosecrans Ave, and Central Ave. Whether you are near Compton College, the Civic Center, or Gateway Towne Center, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Compton — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If your door has only a knob lock, we can bore the door for a deadbolt if the door is thick and solid enough. We check the door first. Call (323) 997-8867 to describe it.
Should I choose a single-cylinder or double-cylinder deadbolt?
Single-cylinder has a thumb turn inside and is easier to exit in an emergency. Double-cylinder needs a key on both sides, which may suit doors with glass nearby but can slow escape in a fire. We go over both before installing.
Will a new deadbolt help in an older Compton tract home?
Often yes, especially with a reinforced strike plate and longer screws into the framing. Older doors and frames can be worn, so we inspect them first and tell you if the door itself needs attention.
Do you come out after a break-in?
Yes. We are available 24/7 and mobile, so we can help secure a door after an attempted or actual break-in. Call (323) 997-8867 and explain the damage to the door or frame.
Can you key several deadbolts alike?
In many cases, yes. If you have front, back, and side doors, we can discuss keying them to a single key so you carry fewer keys.
Do you handle properties with multiple buildings, like Richland Farms?
We can discuss deadbolts for the house and other entries on the property, such as a workshop or outbuilding. Tell us what needs securing when you call.
Is there a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your home or business in Compton and do the installation there.
How do I get a quote?
Price depends on factors such as lock grade, door condition, and the number of doors. Call (323) 997-8867, describe your situation, and we will walk through what affects the cost.
