A standard builder-grade deadbolt does its job on a quiet day, but it was never designed to resist someone who shows up with a pick set, a bump key or a drill. High security locks are built differently. They use tighter tolerances, hardened inserts, anti-drill pins and more complex keyways, and the better ones use restricted keys that cannot be copied at a hardware-store kiosk. If you want a lock that does more than keep honest people honest, this is the upgrade.

Palmdale has a mix of properties that benefit from this kind of hardware. There are 1980s-2000s stucco tract homes with the original builder hardware still on the doors, newer master-planned neighborhoods, apartment complexes, rural large-lot parcels, and commercial and industrial storefronts. Each one has a different threat profile and a different budget, so we start by looking at the actual door and the actual risk rather than selling one product to everyone.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar leads the work. We are mobile only, with no storefront to visit. We bring the tools and hardware to your property, explain the options plainly, and install the lock on site.

How it works in Palmdale

  1. 1

    Talk through what you want to protect

    Call (323) 997-8867 and tell us about the door: front entry, garage access, a detached shop, a business back door or a storage room. We ask who currently holds keys and whether you have had a break-in or a lost key. That tells us whether you need a stronger deadbolt, a restricted keyway, a master-key setup or all three.

  2. 2

    Inspect the door, frame and strike

    A high security cylinder is only as strong as the door around it. On site we check the door thickness, the bore holes, the strike plate and the screws, and the frame. Many tract-home doors have short strike screws and thin frames, so we flag those weak points and recommend reinforcement where it makes sense.

  3. 3

    Choose the lock and key control level

    We explain the difference between a pick- and bump-resistant cylinder, a drill-resistant one and a restricted-key system. Restricted keys mean duplicates can only be made through an authorized process, which matters for rentals, shared properties and businesses with staff turnover. You pick the level that fits.

  4. 4

    Install and fit the hardware

    We remove the old hardware, install the new cylinder or deadbolt, and align the bolt and strike so it throws smoothly without forcing. Cheap locks fail when they bind, so correct alignment is part of the job, not an extra.

  5. 5

    Test, cut keys and hand over

    We test the lock repeatedly from both sides, confirm every key works, and walk you through key control and how to request additional keys. If you are rekeying multiple doors to one key, we set that up before we leave.

What affects the price

  • The grade and brand of the lock itself, since pick-, bump- and drill-resistant hardware varies widely in construction.
  • Whether you want a standard keyway or a restricted key system with controlled duplication.
  • The number of doors, and whether they need to be keyed alike or run on a master-key system.
  • Door and frame condition, including whether the strike plate, bore or frame needs reinforcement.
  • Commercial needs such as aluminum storefront hardware, which can require specialty cylinders and fittings.
  • Time of day, since we work 24/7 and after-hours service is priced differently than scheduled daytime work.

Why Palmdale chooses us

  • Fully mobile service: we install on your property, so there is no trip to a shop and no door left unsecured.
  • Serving the region since 1987, with owner David Shar leading the work rather than handing it off blindly.
  • We evaluate the door and frame first, because upgrading only the cylinder on a weak door wastes your money.
  • We explain restricted keys and key control honestly, including when a standard quality deadbolt is enough.
  • Experience with both residential and commercial hardware, including master-key and restricted-key systems.
  • Available 24/7, so a break-in or lost key at night can be addressed with a proper lock instead of a temporary fix.

High Security Locks across Palmdale

Palmdale's housing stock shapes what people ask us for. In Rancho Vista and Anaverde, many families are aerospace-workforce commuters who work out toward Air Force Plant 42 or drive CA-14 daily. They are often away from the house for long stretches, and after buying a tract home they want the builder-grade locks replaced with something sturdier and re-keyed so no unknown keys remain. Master-planned City Ranch and Anaverde homes often have attractive entry doors fitted with basic hardware, so a high security deadbolt is a sensible upgrade there.

Around Downtown Palmdale and Palmdale Blvd, older homes and apartment complexes bring different needs. Property managers handling rental turnover often prefer restricted keys, so a former tenant cannot simply copy a key. Further out toward Lake Los Angeles and parts of Quartz Hill, larger rural parcels with detached garages, sheds and long driveways are a bigger target because neighbors are farther away, and stronger cylinders on outbuildings are worth considering. We serve ZIP codes including 93550, 93551, 93552 and 93591.

On the commercial side, businesses near the Antelope Valley Mall, along Sierra Highway and in the Plant 42 corridor often have aluminum storefront doors, master-key requirements and keypad locks stressed by Antelope Valley heat. We can look at the existing hardware and recommend a high security option that suits the door and the climate. Whether you are off Avenue S, 10th Street West or Pearblossom Hwy, call (323) 997-8867.

High Security Locks in Palmdale — FAQs

What makes a lock "high security"?
It generally combines tighter manufacturing tolerances, pick- and bump-resistant internals, hardened parts that resist drilling, and often a restricted keyway. Call (323) 997-8867 and we will explain what fits your door.
Do you come to me in Palmdale?
Yes. We are fully mobile and serve Palmdale 24/7, including Rancho Vista, Anaverde, City Ranch, Quartz Hill and Lake Los Angeles. There is no storefront to visit; call (323) 997-8867.
Will a high security lock stop a break-in?
It makes lock-based attacks like picking, bumping and drilling much harder, but doors, frames and windows matter too. We check the strike plate and frame so the whole entry point is stronger, not just the cylinder.
What is a restricted key?
A restricted key uses a keyway and blank that are controlled, so duplicates can't be cut casually. That helps rental properties, offices and families who want to know exactly how many keys exist.
Can you install these on my existing doors?
Usually yes. Most standard residential and many commercial doors accept high security cylinders and deadbolts. We inspect the bore, door thickness and frame first and tell you honestly if something needs adjusting.
Is it useful for rental properties?
Yes. Restricted keys and keyed-alike setups help property managers control access between tenants. We can also handle batched rekeys, and you can reach us at (323) 997-8867 to plan multiple units.
Do you work on commercial storefronts and master-key systems?
Yes. We service aluminum storefront doors, master-key and restricted-key systems, and can look at keypad locks affected by desert heat.
How do I get a quote?
Price depends on lock grade, number of doors, key control level and door condition. Call (323) 997-8867, describe your doors, and we will explain what drives the cost before work begins.
