A standard builder-grade deadbolt is designed to keep an honest door closed, not to withstand someone who is determined to get through it. A high security lock is different in how it is built: tighter tolerances, hardened inserts that resist drilling, pin and cylinder designs that frustrate picking and bumping, and keys that are controlled so they cannot simply be copied at any hardware kiosk. For many Glendale households and properties, that upgrade is one of the more sensible security decisions available.

Glendale makes the question interesting because the building stock is so varied. There are 1920s Spanish and Mediterranean Revival houses with original mortise hardware, hillside custom homes above the city, a large number of 1960s to 1980s apartments and condos with basic wafer entry locks and intercom systems, high-rise residences and offices along Brand Boulevard with fob access control, and aluminum-storefront retail downtown. Each of those calls for a different approach, and a single product recommendation would be wrong for most of them.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We look at the actual door, frame, strike and existing hardware where you are, then explain the options plainly, including when a simpler fix is enough and when a true high security cylinder is worth it.

How it works in Glendale

  1. 1

    Talk through the door and the concern

    Call (323) 997-8867 and tell us what you are protecting and why: a recent break-in attempt, a tenant turnover, a lost key you cannot account for, or simply wanting better protection. We ask about the type of door and lock so we arrive prepared.

  2. 2

    On-site assessment of door, frame and hardware

    A strong cylinder is only part of the picture. We check the door material, the strike plate and its screws, the frame condition, and any existing mortise or deadbolt hardware. In older Glendale homes we also look at whether original hardware can be kept and upgraded instead of replaced.

  3. 3

    Choose the right level of protection

    We explain the practical differences between pick-resistant, bump-resistant and drill-resistant designs, and between standard keys and restricted keyways where duplication is controlled. You decide how far to go for each door, and we do not push more than the situation needs.

  4. 4

    Installation and fitting

    We install the new locks, reinforce strikes and frames where it helps, and make sure the bolt throws smoothly and the door closes without binding. Where it makes sense, we can key multiple locks alike so you carry one key.

  5. 5

    Testing and key handoff

    We test every lock and key with you present, show you how key control works for your chosen system, and explain how to request additional keys properly. For multi-unit properties we can document a key plan so the system stays organized after a management change.

What affects the price

  • The type and number of locks involved, such as a single deadbolt versus entry sets, mortise hardware and several doors keyed alike.
  • The security level and key system chosen, since restricted keyways with controlled duplication differ from standard high-security cylinders.
  • The condition of the door and frame, because reinforcing a weak strike, jamb or older wood door adds work beyond the lock itself.
  • Whether existing hardware can be retained and upgraded, which is common with original mortise locks in older homes, or must be replaced.
  • Scale and complexity for buildings, such as rekeying many apartment units or setting up a master-key hierarchy.
  • Timing and location, since after-hours service and the distance to reach you can affect the overall quote.

Why Glendale chooses us

  • Fully mobile and available 24/7, so assessment and installation happen at your door, not in a shop.
  • In business since 1987, with long experience across older mortise hardware and modern high-security cylinders alike.
  • Honest recommendations: if a reinforced strike and a quality deadbolt solve your problem, we will say so instead of overselling.
  • Comfortable with Glendale's mix of historic homes, apartment buildings, high-rise condos and storefronts, so the solution matches the building.
  • Owner-led by David Shar, with a focus on explaining key control and master-key planning clearly.
  • Able to handle related work in the same visit, including rekeying, keyed-alike sets and after-hours mechanical entry.

High Security Locks across Glendale

Glendale's housing tells you a lot about which lock upgrades matter. In Rossmoyne and Adams Hill, many 1920s Spanish and Mediterranean Revival homes still have original mortise hardware with real character. A common request is to have those mortise locks serviced rather than ripped out, then add a modern high security deadbolt and key everything alike. Done carefully, that keeps the look of the door while closing the gap between old charm and present-day security.

Up in Verdugo Woodlands and along the hillsides below the Verdugo Mountains, mid-century and newer custom homes often have long driveways, side gates and multiple entry points. Here the focus is usually on the main entries, garage-to-house doors and any detached structures, with a consistent key system across them. In ZIP code 91206 and the surrounding area, residents commonly ask us to look at the whole perimeter, not only the front door.

Closer to the center of the city, around Brand Boulevard, The Americana at Brand and the Glendale Galleria, the needs shift to apartments, condos and commercial space. Many 1960s to 1980s apartment buildings in 91203 and 91205 have basic wafer locks and intercoms, and a property-manager change is a natural moment to rekey 20 or more units and start a fresh master-key system. Brand Boulevard high-rise residents with fob or high-security entries sometimes need after-hours mechanical entry and a rekey. We reach all of it by road via SR-134, SR-2, I-5, Central Avenue, Glenoaks Boulevard or Colorado Street, 24/7.

High Security Locks in Glendale — FAQs

What makes a lock high security instead of standard?
High security locks use tighter manufacturing tolerances, hardened components that resist drilling, and cylinder designs that make picking and bumping much harder. Many also use restricted keys that cannot be freely copied. Call (323) 997-8867 and we can explain what fits your door.
Will a high security lock help if my door or frame is weak?
Only partly. A strong cylinder on a weak jamb or short strike screws can still fail under force. That is why we inspect the door, frame and strike and reinforce them where needed as part of the installation.
Can you keep the original mortise locks in my Rossmoyne or Adams Hill home?
Often, yes. We can service original mortise hardware, add a modern high security deadbolt, and key them alike. Sometimes a part is too worn to rely on, and we will tell you honestly if so.
Can you set up high security locks and a master key system for an apartment building?
Yes. After a property-manager change, many Glendale buildings rekey 20 or more units and start a new master-key hierarchy. We can plan the key structure with you, so call (323) 997-8867 to discuss the property.
I am locked out of my Brand Boulevard condo with a fob or high-security entry. Can you help?
We can provide after-hours mechanical entry and a rekey where appropriate. Call (323) 997-8867 and describe the door and system so we know what to expect. Building rules and access control can affect what is possible, so we will advise you on site.
Are high security keys harder to copy?
Many systems use restricted keyways, meaning duplication is controlled and not available at ordinary key-cutting counters. That helps if you want to know exactly who holds keys. The specifics depend on the system you choose.
Do you have a shop I can visit in Glendale?
No. Crenshaw Lock Company is fully mobile and works 24/7. We come to your home, building or business anywhere in Glendale, so there is no storefront to drive to.
How is the price determined?
It depends on the number and type of locks, the security level and key system, the condition of the door and frame, and the timing of the visit. We do not quote blind. Call (323) 997-8867 and we will explain what drives the cost for your situation.
