A deadbolt is the one piece of hardware on your front door that does the real work of keeping it shut. In Agoura Hills, where so many homes were built in the 1970s and 1980s, a lot of those original bolts have been turning for forty years or more. Springs weaken, cylinders wear, strike plates loosen in their screws, and some doors never had a proper deadbolt at all, only a keyed knob with a latch that can be slipped. Adding or replacing a deadbolt is among the most practical security upgrades a homeowner can make.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on being fully mobile. There is no storefront to visit. We bring the tools, drill guides, hardware and know-how to your door, and we do the work on site, whether that is a single new bolt on a side door or a full set of matched locks for a house.

This page explains how a deadbolt installation typically goes, what affects the cost, and what is specific to doing this work around Agoura Hills: the dry heat that seizes older hardware, the mix of tract homes, condos, horse properties and hillside custom houses, and the different doors each one tends to have. If you would rather talk it through, call (323) 997-8867 and we will help you work out what your door needs.

How it works in Agoura Hills

  1. 1

    Talk through the door and your goal

    We start with a phone conversation. Are you adding a deadbolt where there is none, replacing a worn one, or upgrading after a lockout or a break-in concern? We ask about the door material, whether it has glass nearby, and whether you want everything keyed alike. That helps us bring the right hardware.

  2. 2

    Inspect the door, frame and existing bore holes

    At your home we look at the door's thickness, edge condition, and the frame where the bolt will land. Many 1970s and 1980s doors have standard bore holes that accept a modern deadbolt, but some have been patched, over-drilled or warped, and we tell you honestly what we find before we start.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt turns with a thumbturn inside and a key outside. A double-cylinder needs a key on both sides, which can make sense next to glass but can also slow an emergency exit. We explain the tradeoff plainly and let you decide, keeping in mind local fire and safety considerations.

  4. 4

    Install and reinforce the strike

    We fit the bolt, align the latch and strike, and set the throw so it extends fully into the frame. A longer-screw strike plate or reinforcement into the framing is often the real upgrade, since a strong bolt in a weak jamb does not hold up well.

  5. 5

    Test, key and hand over

    We cycle the lock repeatedly with the door open and closed, check that it operates smoothly, and confirm the keys work. If you want it keyed to match your other locks, we can arrange that. You leave with working keys and a clear idea of how to care for the hardware.

What affects the price

  • Whether you need a new deadbolt added to a door with no bore or a replacement fitted into an existing one, since new boring takes more work.
  • The grade and style of the hardware you choose, from standard residential bolts to heavier-duty options and decorative finishes.
  • Single-cylinder versus double-cylinder, and whether you want several locks keyed alike.
  • Door and frame condition, including whether the jamb needs repair or reinforcement so the bolt seats properly.
  • The number of doors being done in one visit, which can make the trip more efficient.
  • Time and location of the visit, including after-hours or urgent calls, and travel to hillside or gated properties.

Why Agoura Hills chooses us

  • Fully mobile: we do the work at your door, with no shop visit and no need to bring a door anywhere.
  • In business since 1987, with David Shar as owner and lead technician guiding the work.
  • Available 24/7, so a failed deadbolt or an insecure door does not have to wait for business hours.
  • We explain single versus double cylinder and strike reinforcement honestly rather than just selling the priciest option.
  • We pay attention to the door and frame, not just the lock, because installation quality matters as much as the hardware.
  • Experience with the mix of local properties, from tract homes and townhomes to ranch gates and hillside custom doors.

Deadbolt Installation across Agoura Hills

Agoura Hills has several distinct kinds of properties, and each calls for slightly different thinking. Much of the city is made up of 1970s and 1980s tract homes and planned communities, and the front doors on those homes often still carry their original hardware. A homeowner off Kanan Road might call after a deadbolt seized in the summer heat, and in that case we often combine a rekey or replacement with an upgrade to a sturdier bolt and a reinforced strike. Homes in the 91301 area in particular tend to have this older stock.

Old Agoura is a different picture, with semi-rural equestrian properties, barns and gated ranch homes. There we may fit deadbolts on main and guest-house doors, and look at barn padlocks or a worn driveway gate lock while on site. Around Lake Lindero, condos and townhomes often involve association rules about hardware, so it is worth checking before choosing a finish. Morrison Ranch and the hillside custom homes toward Ladyface Mountain often have larger or custom doors, which we measure carefully before choosing hardware.

We reach Agoura Hills by way of US-101, Kanan Road and Agoura Road, and also serve homes in 91376. Whether you live near Chumash Park, the Reyes Adobe Historical Site or Whizin's Market Square, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Agoura Hills — FAQs

Can you add a deadbolt to a door that only has a knob lock?
Usually yes. If the door is thick enough and solid enough, we can bore for a deadbolt and install a strike in the frame. Call (323) 997-8867 and describe the door, and we will tell you what to expect.
Should I choose a single- or double-cylinder deadbolt?
For most homes a single-cylinder with an inside thumbturn is the safer everyday choice because you can exit quickly without a key. A double-cylinder can make sense near glass, but we discuss the emergency-exit tradeoff first.
My deadbolt seized in the heat. Do I need a new one?
Not always, but heat, dust and wear in older hardware can cause binding. We inspect it and tell you whether cleaning, rekeying or full replacement makes sense. If you are locked out now, call (323) 997-8867.
Do you install deadbolts at night or on weekends?
Yes. We are available 24/7 and fully mobile, so we can come to you at any hour. We do not promise specific arrival times, but we will talk through the situation when you call.
Will a new deadbolt work on my old door?
Often, yes, as long as the door is solid and the bore is standard. Warped, cracked or over-drilled doors may need repair first. We check this before installing anything.
Can you key all my locks the same?
In most cases we can arrange for several new deadbolts to use one key, depending on the hardware brand and what your existing locks are.
Do you work on gate locks and barn padlocks on horse properties?
Yes, we can look at driveway gate locks and barn padlocks as well as the house doors. Tell us what you have when you call (323) 997-8867 so we can bring the right parts.
Do I need to check with my HOA before changing a deadbolt?
In townhome and condo communities, it is a good idea. Some associations specify finish or brand for exterior hardware. Check your rules, and we will work within them.
