Much of La Puente was built in the 1950s and 60s as single-story stucco tract housing, and plenty of those front doors still carry the lockset the builder installed decades ago. Those older deadbolts have often been rekeyed, sprayed with lubricant, forced, or left to sag as doors warp in the sun. A new deadbolt is one of the most practical security upgrades a homeowner or renter can make, and it is usually a straightforward job when the door and frame are sound.

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: there is no storefront to visit. We bring the hardware, tools, and know-how to your property, whether that is a tract home near La Puente Park, a converted-garage ADU, or a shop on Valley Boulevard.

Deadbolt work is not just swapping a part. The door's thickness, the bore holes, the strike plate, the frame, and how you actually use the door all matter. We look at those details first, then recommend a single-cylinder or double-cylinder deadbolt, a keyed-alike setup across several doors, or a repair if a realignment will solve the problem. We are available around the clock, including nights and weekends, when a failed lock cannot wait.

How it works in La Puente

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: wood, metal, or aluminum storefront, whether there is already a deadbolt, and what is going wrong. That helps us bring suitable hardware, since we work from our mobile setup.

  2. 2

    Inspect the door and frame

    On site we check the door's thickness, existing bore holes, the edge alignment, and the condition of the jamb. On older stucco-home doors, sun warping and settled frames are common culprits behind a sticking bolt, so we look for those first.

  3. 3

    Choose the right deadbolt

    We explain single-cylinder versus double-cylinder options in plain terms. A double-cylinder requires a key on both sides, which can matter near glass but also affects fast exit in an emergency, so we talk through the tradeoffs and local fire-safety considerations before you decide.

  4. 4

    Install and align

    We fit the deadbolt, set the strike plate, and reinforce the jamb area where appropriate. The bolt should throw smoothly and fully into the frame without forcing the door. If the door has shifted, we correct the alignment rather than just masking it.

  5. 5

    Key and test

    We cut or set keys, and where you have multiple doors, such as a main house and a garage-conversion unit, we can set them keyed-alike so one key works for each. We test every key and the thumb turn several times.

  6. 6

    Walk-through and care tips

    Before we leave, we show you how the lock operates and how to keep it working, and we hand over all the keys. If we noticed any other weak points on the door, we tell you honestly and leave the decision to you.

What affects the price

  • Whether you are adding a new deadbolt to a door that has none or replacing an existing one, since new installs may require drilling and fitting additional bore holes.
  • Single-cylinder versus double-cylinder, and the grade and brand of hardware you choose.
  • Door material and condition, including warped wood, hollow-core doors, metal doors, or aluminum storefront frames with unusual cutouts.
  • Number of doors and whether they need to be keyed-alike, such as a main house plus an ADU or converted garage.
  • Any added work like jamb reinforcement, strike plate upgrades, or realigning a door that has shifted.
  • Time of service: after-hours, weekend, and holiday calls are handled around the clock, and timing can influence the quote.

Why La Puente chooses us

  • Fully mobile service: we come to your home or business, with no storefront trip and no need to remove the door.
  • Serving the region since 1987, so we have seen the aging hardware common in 1950s and 60s tract homes many times over.
  • Owner-led operation under David Shar, so the standards for craftsmanship come from the top.
  • Honest recommendations: if a realignment or a strike plate fix solves a sticking deadbolt, we say so rather than selling a full replacement.
  • Residential and light commercial experience, including keyed-alike setups for multi-door properties and aluminum storefront doors.
  • Available 24/7, so a broken or compromised lock can be dealt with when it happens.

Deadbolt Installation across La Puente

La Puente's streets are lined with modest single-story stucco homes, and on the Valinda and Bassett sides of town we often see original or builder-grade entry hardware that has been in service for decades. Sun exposure can swell and warp older wood doors, which is why a deadbolt that worked fine last winter may refuse to turn in summer. In ZIP 91744 and nearby 91746 and 91747, a deadbolt install is often paired with a quick alignment check so the new lock performs well for years.

Landlords in the Hudson and Sunset areas frequently have converted garages and ADUs behind the main house. When tenants change, it makes sense to rekey or replace the deadbolts and set the main house and unit keyed-alike when that suits how you manage the property. We can handle several doors in one visit.

Businesses along Valley Boulevard and the Hacienda Boulevard retail strip, near landmarks like The Donut Hole, often have aluminum-storefront doors with narrow stiles that need specific cylinders and hardware. If a storefront deadbolt or pivot fails, we can assess it on site and swap the cylinder or hardware. Whether you are off Amar Road, near La Puente Park, or just off the I-10 or SR-60, our mobile service comes to you.

Deadbolt Installation in La Puente — FAQs

Do you install deadbolts on homes in La Puente at night or on weekends?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour to arrange deadbolt installation or an urgent lock fix.
Should I choose a single-cylinder or double-cylinder deadbolt?
A single-cylinder uses a key outside and a thumb turn inside, which is easier to exit quickly. A double-cylinder needs a key on both sides and is sometimes used near glass, but can slow escape in an emergency. We will explain both for your door before you decide.
My deadbolt sticks in warm weather. Do I need a new one?
Not always. In older tract homes, sun-warped doors or shifted frames often cause sticking. We check alignment first and replace the lock only if it is worn or damaged.
Can you make the main house and my ADU use the same key?
Yes. We can install or rekey deadbolts so the main house and a converted garage or ADU are keyed-alike. Call (323) 997-8867 to discuss how many doors you have.
Can you install a deadbolt on a door that does not have one?
Usually, yes, if the door is thick and solid enough. We drill the needed holes, fit the bolt, and install a strike plate. Very thin or hollow doors may need extra reinforcement, which we will tell you about.
Do you work on storefront doors along Valley Boulevard?
Yes. We handle commercial cylinder swaps and deadbolt hardware on aluminum-storefront doors. Call (323) 997-8867 and describe the door so we can bring appropriate parts.
Do I have to visit a shop?
No. Crenshaw Lock Company is mobile only. We bring everything to your La Puente home or business and complete the work there.
How much does deadbolt installation cost?
It depends on the hardware, door type and condition, number of doors, and any extra work like reinforcement. We will talk through those factors and give you a clear quote before starting.
