A deadbolt is one of the simplest and most effective upgrades you can make to a door. In Paramount, where so much of the housing is post-war single-family tract homes and older bungalows, many doors still carry the original knob lock and little else. A properly installed deadbolt gives you a solid steel bolt that seats deep into the frame, which is a big step up from a spring latch that can be slipped or forced.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business on showing up where the customer is. We are fully mobile and available 24/7. There is no storefront to drive to; we bring the hardware and tools to your door, whether that is a house near Progress Park, an apartment off Paramount Boulevard, or a business unit near the rail corridor.

Installation is more than drilling a hole. Door thickness, edge condition, strike plate, frame strength, and how the door is actually used all affect which deadbolt makes sense. We look at the whole door and explain your options plainly, so you end up with a lock that fits the door and the way you live.

How it works in Paramount

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe the door: exterior or interior, wood, metal, or fiberglass, and whether you have an existing lock or a blank door. Mention if you want a new deadbolt added, an old one replaced, or all exterior locks matched to one key.

  2. 2

    Inspect the door and frame

    On arrival we check the door thickness, the condition of the edge, and the frame where the bolt will land. Older Paramount homes sometimes have worn or split jambs, and a strong lock in a weak frame does not do much, so we point out anything that needs attention.

  3. 3

    Choose the right deadbolt

    We go over single-cylinder versus double-cylinder options. A single cylinder turns with a thumbturn inside, which is easiest and safest for most households. A double cylinder needs a key on both sides and is only sensible in specific situations, such as doors with glass nearby, and we talk through the fire-exit tradeoffs honestly.

  4. 4

    Install and reinforce

    We prepare the door, mount the deadbolt, and fit a strike plate secured with long screws that reach into the framing rather than just the thin jamb trim. If the bore holes are already present from a prior lock, we work with them where possible.

  5. 5

    Test and hand over keys

    We cycle the bolt repeatedly with the door open and closed, check alignment, and confirm it throws fully without binding. You get your keys, and if you want, we can key new locks alike so one key works on every exterior door.

What affects the price

  • Whether you are adding a brand-new deadbolt to a door or replacing an existing one, since a new install may need holes drilled.
  • The grade and style of deadbolt you select, from standard residential hardware to higher-security, pick- and drill-resistant models.
  • Single-cylinder versus double-cylinder configuration and any finish you want to match existing hardware.
  • The condition and material of the door and frame, including whether the jamb needs repair or a reinforced strike plate.
  • How many doors are being done in one visit, including keying several locks alike.
  • Time of day and urgency, since we serve after-hours and overnight calls as well as scheduled daytime work.

Why Paramount chooses us

  • Fully mobile service: we come to your Paramount address with hardware on the truck, so there is no shop trip and no waiting for a part order in most cases.
  • Operating since 1987, with owner and lead tech David Shar guiding the standards we work to.
  • Open 24/7, so a burglary-related door repair or an urgent upgrade does not have to wait for business hours.
  • We pay attention to the frame and strike, not just the lock body, because a deadbolt is only as strong as what it bolts into.
  • Honest advice on single versus double cylinder, including when we would recommend against a double cylinder for safety reasons.
  • Experience across residential, apartment, and light commercial doors, which matters in a city with both post-war homes and industrial and retail properties.

Deadbolt Installation across Paramount

Paramount grew out of the historic Clearwater and Hynes communities, and much of that character shows in the doors. Many homes in the 90723 ZIP code are 1940s and 1950s single-family tract houses, with a scattering of 1920s bungalows and later apartment buildings. Original hardware on these homes is often a basic knob set, and a lot of buyers in the Clearwater area ask us to upgrade the deadbolts and rekey every exterior door at move-in so nobody from the previous owner's time still holds a key.

Around the Paramount Boulevard corridor and the Paramount Boulevard business district, we also see storefronts and small commercial doors that benefit from a solid deadbolt. The Paramount Swap Meet draws vendors and shoppers alike, and nearby retailers sometimes need locks added or changed quickly. Further along the rail and I-710 corridor, industrial properties, including metal shops, often want sturdier hardware on office and side doors in addition to yard padlocks and gate latches.

We reach customers across the city using routes like Rosecrans Avenue, Alondra Boulevard, Somerset Boulevard, Lakewood Boulevard, I-710, and SR-91. Whether you live near Progress Park or work near the Zamboni headquarters area, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Paramount — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door is thick enough and in sound condition, we can drill the holes, mount the deadbolt, and fit a strike plate. Call (323) 997-8867 with a description of your door and we will tell you what to expect.
Should I get a single-cylinder or double-cylinder deadbolt?
For most homes, single cylinder is the better choice because you can open it quickly from inside without a key, which matters in an emergency. Double cylinder can make sense when there is glass near the lock, but it can slow an exit, so we discuss the tradeoffs before installing.
Is deadbolt installation available at night or on weekends in Paramount?
Yes. We are mobile and available 24/7, including nights, weekends, and holidays. You can reach us any time at (323) 997-8867.
I just bought a post-war home near Clearwater. What should I do about the locks?
A common approach is to rekey or replace all exterior locks and upgrade any worn or missing deadbolts. That way only the keys you hold work, and the doors have stronger hardware than the original knob locks.
Will a new deadbolt make my door secure if the frame is old?
Not entirely. The bolt needs solid wood to seat into. On older homes we often reinforce the strike plate with long screws, and we will let you know if the jamb itself needs repair.
Can you match all my deadbolts to one key?
Yes. We can key new deadbolts to match each other or to your existing locks where compatible, so you carry fewer keys.
Do you install deadbolts for businesses or swap meet booths?
Yes, we handle light commercial doors, storefronts, and shop entrances in addition to homes. Call (323) 997-8867 to discuss the door and what kind of security you need.
Do I need to come to a shop to pick out a deadbolt?
No. Crenshaw Lock Company is mobile only, so there is no storefront. We bring options to you and install on the spot.
