Signal Hill is a small hilltop city sitting entirely inside Long Beach, and its mix of properties is unusual: older homes, hillside townhomes and condos built on redeveloped oil land, an auto dealership row, and industrial parcels that still sit beside working oil pumps. A standard builder-grade deadbolt protects very different things in each of those settings, and often it is not enough.

High security locks are built to resist the methods burglars actually use: picking, bumping, drilling, and forced removal of the cylinder. They are paired with keys that are restricted, meaning copies cannot be cut at a random kiosk or hardware counter. That matters when you want to know exactly who holds a key to your door, gate or storeroom.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner David Shar. We are mobile only, with no storefront, so every job is done on site. We look at your door, your frame, your hardware and how you use the property, then recommend a lock that fits instead of the most expensive one on the shelf.

How it works in Signal Hill

  1. 1

    Talk through the property

    Call (323) 997-8867 and tell us what you are protecting: a hillside townhome, a view condo, a dealership office, or a gate at an industrial parcel. We ask about current locks, past problems and who needs keys.

  2. 2

    On-site assessment

    We come to you and examine the door, strike plate, frame, and existing cylinders. A strong lock in a weak door or loose frame only moves the weak point, so we check the whole assembly, including HOA or building rules that may limit what can be changed.

  3. 3

    Choose the right hardware

    We explain the options in plain terms: pick-resistant and bump-resistant cylinders, drill-resistant hardened inserts, and restricted key systems. For newer homes with keypads or smart locks, we discuss how a high-security deadbolt can work alongside them as a mechanical backup.

  4. 4

    Installation and reinforcement

    We install the new cylinders or deadbolts, and where needed reinforce the strike plate and frame so the door resists force as well as picking. For gates and padlock hasps, we match hardware to outdoor and corrosive conditions.

  5. 5

    Key setup and testing

    We cut and test your restricted keys, confirm smooth operation from both sides, and walk you through how to request additional keys through proper authorization.

  6. 6

    Handover and follow-up advice

    You receive clear guidance on key control, what to do if a key goes missing, and when rekeying makes sense, such as after a tenant, employee or contractor leaves.

What affects the price

  • The grade and type of lock chosen, since restricted-keyway systems with drill-resistant hardening cost more to produce than standard cylinders.
  • The number of doors, gates or padlocks being converted, and whether they can all be keyed alike or need separate keys.
  • The condition of the door and frame, including whether reinforcement of strike plates or jambs is needed for the lock to actually perform.
  • The number of restricted keys needed and any later authorization steps for duplicates.
  • Environmental wear, such as corroded or seized cylinders on oil-field or outdoor gates that require extra labor to free or replace.
  • Timing of the visit, since after-hours and emergency calls differ from scheduled daytime appointments.

Why Signal Hill chooses us

  • Fully mobile service: we come to your door, gate or lot in Signal Hill, with no storefront and no need to bring hardware to us.
  • In business since 1987, with David Shar leading the work, so experience with older locks and hardware is behind each recommendation.
  • We evaluate the door and frame, not just the cylinder, because high-security hardware is only as strong as what it is mounted in.
  • Honest recommendations: if a rekey or a standard upgrade solves your problem, we will say so instead of upselling.
  • Comfortable with mixed property types, from hillside townhomes with keypads to dealership offices and industrial gates.
  • Available 24/7, so a break-in aftermath or a lost restricted key does not have to wait for business hours.

High Security Locks across Signal Hill

Signal Hill's housing tells the story of its history. On the Hilltop, around the summit and near Hilltop Park, you find view homes, condos and townhomes, many built in the 1990s and 2000s on former oil land. Those newer properties often rely on keypads, smart locks and HOA access systems, and a backup high-security deadbolt can be a sensible layer when electronics fail or a code has been shared too widely.

In the Discovery Well district, near Discovery Well Park where oil was found in 1921, older homes sit close to parcels of the still-active oil field. Perimeter gates and padlocks there face weather, dust and corrosion, and seized cylinders are common. We can free up, rekey or replace them with hardened hardware suited to the conditions. The Panorama Promenade connecting the two parks is a reminder of how close very different property types sit to each other here.

Along the Cherry Avenue auto corridor and the Signal Hill Auto Center, dealerships have their own needs: restricted keys for offices and key rooms, and control over who can copy them. Whether you are off I-405, on Spring St, Willow St or California Ave, or anywhere else in ZIP code 90755, call (323) 997-8867 and we will come to you.

High Security Locks in Signal Hill — FAQs

What makes a lock high security?
High security locks resist picking, bumping and drilling through tighter internal tolerances, hardened inserts and more complex pin designs. Many also use restricted keys that cannot be freely duplicated.
Do you offer high security locks in Signal Hill at night?
Yes. We are a 24/7 mobile locksmith. Call (323) 997-8867 at any hour and we will talk through what you need.
Can a high security deadbolt work with my smart lock or keypad?
Often yes. Many Signal Hill townhomes and condos use electronic locks, and a mechanical high-security deadbolt can serve as a reliable backup if the electronics fail. We check your door and any HOA rules first.
Can you help with corroded gate locks near the oil field?
Yes. Perimeter gates and padlocks on oil or industrial parcels can seize from corrosion. We can free them, rekey them, or replace them with hardware suited to outdoor conditions. Call (323) 997-8867 to describe the gate.
What is a restricted key and why does it matter?
A restricted key is cut on a protected blank, and duplicates require authorization. That gives you better control over who has access, which helps landlords, businesses and homeowners alike.
Will a better lock help if my door is weak?
Only partly. Strong cylinders should be paired with a solid door, a reinforced strike plate and a sound frame. We inspect all of these during the visit.
Can dealerships on Cherry Ave get high security locks for offices and key rooms?
Yes. We can install restricted-key hardware for offices, key cabinets and storage areas, and discuss key control practices that fit your staff and inventory.
Do I need to visit your shop?
No. We are mobile only and have no storefront. We come to your property in Signal Hill, and you can reach us at (323) 997-8867.
