A deadbolt is one of the simplest upgrades that makes a real difference to a door. Builder-grade hardware, worn bolts, loose strike plates and doors that never had a deadbolt at all are common, and in a community as varied as Tarzana the right fix depends heavily on the building. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and installing deadbolts is everyday work for owner and lead tech David Shar and the team.

We are fully mobile and available around the clock. There is no storefront to visit; we bring the hardware and tools to your property, look at the door in person, and fit the lock on site. That matters because a deadbolt is only as strong as the door and frame around it. Door thickness, bore holes, the strike plate and the screws that hold it in all affect how well a new lock performs.

We can add a deadbolt where there is none, replace an old or failing one, swap a single-cylinder for a double-cylinder where it makes sense, or match new locks to the keying you already use. We will explain trade-offs plainly, including when a double-cylinder is a poor idea, so you choose with full information rather than a sales pitch.

How it works in Tarzana

  1. 1

    Call and describe the door

    Phone (323) 997-8867 any hour. Tell us about the door: exterior or interior, wood, metal or fiberglass, whether it already has a deadbolt, and what's prompting the change, such as a move, a lost key or a break-in attempt.

  2. 2

    On-site door and frame check

    We come to you in Tarzana and inspect the door edge, the existing bore holes, the thickness, and the frame. A deadbolt in a weak or split frame won't do much, so we point out problems before we start.

  3. 3

    Choose cylinder type and keying

    We walk through single-cylinder (thumb turn inside) versus double-cylinder (key on both sides), plus keyed-alike options so one key can work several doors. We note egress and safety considerations with a double-cylinder, especially in homes with children or in rental units.

  4. 4

    Install and reinforce

    We fit the deadbolt, drilling or adjusting the door as needed, and set the strike plate. Where the frame is soft, we recommend longer screws or a reinforced strike so the bolt anchors into the structure, not just the trim.

  5. 5

    Test and hand over keys

    We cycle the bolt repeatedly, check alignment with the door closed and latched, and confirm every key works. You get the keys and a quick explanation of any maintenance, like occasional lubrication.

What affects the price

  • Single-cylinder versus double-cylinder hardware, and the grade and finish of the deadbolt you select
  • Whether the door is already bored for a deadbolt or needs new holes drilled, which depends on door material
  • Number of deadbolts being installed or keyed alike in the same visit
  • Frame and strike reinforcement needed, such as longer screws or a heavier strike plate
  • Smart or keypad deadbolts versus traditional mechanical ones
  • Time of day and urgency, since we operate 24/7 and after-hours calls differ from scheduled visits

Why Tarzana chooses us

  • Fully mobile service: we work at your door, so we assess the real door and frame instead of guessing over the phone
  • In business since 1987, with owner David Shar personally leading the work
  • We tell you when a double-cylinder deadbolt is a bad fit for your household, rather than defaulting to the pricier option
  • Experience across very different Tarzana buildings, from 1950s flats ranch homes to gated hillside properties and professional suites
  • Keying flexibility, including matching new deadbolts to existing keys so you carry fewer keys
  • Available 24/7 for urgent situations like a door that no longer secures after a break-in attempt

Deadbolt Installation across Tarzana

Tarzana sits on both sides of Ventura Boulevard, and the doors differ accordingly. North of the Boulevard on the Tarzana flats, many homes are 1950s ranch houses and apartments along streets near Reseda Blvd, Tampa Ave and Lindley Ave. These often have original or mixed builder hardware, and the front door may have a worn latch, no deadbolt, or a lock that has been replaced piecemeal over decades. A properly fitted deadbolt with a reinforced strike plate is a practical upgrade in 91356 and 91335-adjacent blocks alike, and we have handled situations like a seized older front-door lock where the job turned into removing it and rebuilding the setup.

South of the Boulevard, the Santa Monica Mountains hillside around Mulholland Dr holds larger custom homes and gated estates, many in 91356 and 91357. Here the deadbolt is often one layer among a driveway gate, intercom and smart lock. After a change in household staff, owners sometimes want to rekey or add deadbolts and coordinate with smart-lock settings. We can install deadbolts that fit the heavier solid doors common on these properties and discuss how they work alongside electronic access.

Along the Ventura Blvd medical and commercial corridor, near Providence Cedars-Sinai Tarzana Medical Center, suites and offices have their own needs, such as keyed-alike or master-keyed hardware and rekeying after staffing changes. Whether you are near the El Caballero Country Club, the Tarzana Recreation Center, or just off the 101, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Tarzana — FAQs

Can you install a deadbolt on a door that doesn't have one?
Usually yes. We check the door's thickness and material, drill the needed holes for the bolt and cylinder, and set the strike in the frame. Call (323) 997-8867 and describe the door so we can bring the right hardware.
What is the difference between single- and double-cylinder deadbolts?
A single-cylinder uses a key outside and a thumb turn inside. A double-cylinder needs a key on both sides. Double-cylinders can help where glass is near the lock, but they can slow exit in an emergency, so we discuss it with you first.
Do you offer deadbolt installation at night or on weekends in Tarzana?
Yes. We are 24/7 and fully mobile, so you can call (323) 997-8867 at any hour about a door that needs securing, including after a break-in attempt.
Will a new deadbolt help if my door frame is weak?
Only partly. A strong bolt needs a solid frame and strike plate. We inspect the frame and can recommend longer screws or a reinforced strike so the lock anchors properly.
Can several doors use the same key?
Yes. We can key deadbolts alike so one key works front, back and side doors, or match them to a lock you already have. This is handy for homes and small offices.
Can you add deadbolts at a hillside estate with a gate and smart lock?
We can install mechanical deadbolts on estate doors and talk through how they sit alongside smart locks and gate systems. Call (323) 997-8867 to describe your setup.
Do you have a shop I can visit?
No. We are mobile only, with no storefront. We come to your home or office in Tarzana, so you don't need to travel anywhere.
Can you replace an old deadbolt rather than add a new one?
Yes. Replacement is common when a bolt sticks, the cylinder is worn, or keys have been lost. We fit a new deadbolt to the existing holes where possible, which keeps changes to the door minimal.
