A deadbolt is only as strong as the door and frame it sits in. In Glendale that matters, because the housing stock is so varied: 1920s Spanish and Mediterranean Revival homes with thick original doors, hillside custom houses with heavy entry doors, and a large number of 1960s to 1980s apartments and condos where the front door may have only a basic wafer or entry knob lock. Each of these calls for a different approach, and we start by looking at the door rather than selling a one-size-fits-all product.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has handled just about every door situation this region produces. We are mobile only. There is no storefront to visit; we bring the work to you, at any hour, whether you are adding a first deadbolt, upgrading a worn one, or replacing hardware after a break-in attempt or a move.

Good installation is about details most people never see: a properly bored hole, a correctly set backset, a strike plate anchored into the framing rather than just the trim, and a bolt that throws cleanly into the jamb. We explain the choices, such as single or double cylinder, key-alike with your existing locks, and grade of hardware, so you can decide with clear information.

How it works in Glendale

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask about the door material, whether you already have a deadbolt, and what you want: more security, keyed-alike convenience, or a replacement for a worn lock. That lets us arrive with suitable hardware.

  2. 2

    Inspect the door, frame and existing hardware

    On site we check the door thickness, the condition of the frame, and any existing bores. Older Glendale doors may have mortise pockets or past repairs that affect where and how a new deadbolt can go.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt has a thumbturn inside. A double-cylinder needs a key on both sides, which can be useful near glass but matters for emergency exit. We explain the tradeoffs and local fire-safety considerations so you can choose.

  4. 4

    Install and reinforce the strike

    We fit the deadbolt, set the bolt to extend fully into the jamb, and install a strike plate with longer screws that reach the framing behind the trim. This is where much of the real-world resistance to forced entry comes from.

  5. 5

    Key, test and hand over

    We can key the new deadbolt to match your other locks if the hardware allows. We test the bolt, latch and keys repeatedly with the door open and closed, then walk you through operation before we leave.

What affects the price

  • Whether you need a brand-new bore drilled in the door or are replacing an existing deadbolt in an existing hole
  • Hardware grade and brand, from standard residential deadbolts to higher-security, pick- and drill-resistant models
  • Single-cylinder versus double-cylinder, and whether the lock must be keyed alike with other locks on the property
  • Door material and condition, such as solid wood, hollow-core, metal or an older door that needs repair before a lock will hold
  • How many doors are involved, which matters for apartment buildings and multi-unit properties
  • Time of day and location, since we are available 24/7 and after-hours calls differ from scheduled daytime work

Deadbolt Installation across Glendale

Glendale's older neighborhoods set the tone for a lot of our deadbolt work. In Rossmoyne and Adams Hill, many 1920s Spanish and Mediterranean Revival homes still have original mortise hardware and solid, sometimes arched doors. A common request is to have the original locks serviced and add a new deadbolt that is keyed alike, so one key works throughout without losing the character of the door. We fit hardware carefully so that historic doors are not cut more than necessary.

Up in Verdugo Woodlands and along the slopes beneath the Verdugo Mountains, hillside mid-century and newer custom homes often have heavy entry doors, side gates and secondary doors that deserve the same attention as the front. In ZIP codes like 91208 and 91206, we are regularly asked to add deadbolts to garage-side and patio doors that were never secured as well as the main entrance.

For apartments and condos, the picture is different. Glendale has a high share of renters, and many 1960s to 1980s buildings near Brand Boulevard, Central Avenue and Colorado Street have basic entry locks. Whether you are in 91203, 91205 or near The Americana at Brand and the Glendale Galleria, we can add or replace deadbolts and, for property managers, handle several units in one visit. Call (323) 997-8867 for any Glendale address, reached via SR-134, SR-2 or I-5.

Deadbolt Installation in Glendale — FAQs

Can you install a deadbolt on a door that doesn't have one?
Yes, in most cases. If the door is thick enough and structurally sound, we can drill the proper bores and install a new deadbolt. We check the door and frame first. Call (323) 997-8867 to describe your door.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder is the usual choice for most homes because the inside thumbturn allows quick exit. Double-cylinder may suit doors with glass nearby, but it needs a key to open from inside, which can be a safety concern in an emergency. We help you weigh this.
Can the new deadbolt match my existing key?
Often yes. We can key a new deadbolt to match your other locks if the hardware is compatible, so you carry one key. This is popular in Rossmoyne and Adams Hill homes where original locks are being kept.
Do you work on old Spanish Revival doors with mortise locks?
Yes. Many 1920s Glendale homes have original mortise hardware. We can service those locks and add a deadbolt carefully so the door's character is preserved. Call (323) 997-8867 to discuss your door.
I manage an apartment building. Can you handle multiple units?
Yes. We can install or replace deadbolts across several units and coordinate keying, including keyed-alike or master-key arrangements where appropriate. Tell us the number of doors and door types when you call.
Will a deadbolt alone stop a forced entry?
No lock is unbeatable, but a quality deadbolt with a reinforced strike plate and long screws into the framing greatly improves resistance. That is why we inspect and reinforce the frame, not just the lock.
Do you come out at night or on weekends?
Yes. We are available 24/7 and fully mobile. If your lock was damaged in a break-in or you need a door secured tonight, call (323) 997-8867.
How is the price determined?
Price depends on whether a new bore is needed, hardware grade, cylinder type, keying, door condition and number of doors. We discuss these with you so you understand what drives the cost before work starts.
