A deadbolt is one of the simplest upgrades you can make to a door, and one of the most effective. In Mission Hills, where so many homes date from the late 1940s through the 1960s, the original hardware is often a worn cylinder knob with no deadbolt at all, or an older lock that has been loosened by decades of use. Adding a properly fitted deadbolt gives the door a solid steel bolt that sits deep in the frame, and it is usually the first thing we recommend after a move, a break-in scare, or a resale.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our team are fully mobile. There is no storefront to visit. We bring the hardware, drilling tools, and strike plates to your property, whether that is a stucco ranch on a quiet street near Mission San Fernando Rey de Espana or a professional office along Sepulveda Boulevard. We work around the clock, so a door that will not secure at night does not have to wait for morning.

A good installation is more than the lock itself. The bore has to be clean and square, the latch and bolt have to line up with the strike, and the frame has to be strong enough to hold when someone pushes on it. We look at all of that, explain your options in plain language, and leave the door working smoothly with keys that turn easily.

How it works in Mission Hills

  1. 1

    Talk through the door and your goals

    When you call (323) 997-8867, we ask about the door, whether you need a new deadbolt or a replacement, and what is driving the change: a move, a lost key, a security concern, or a resale. Knowing whether it is a front door, a back slider-adjacent entry, or an office door helps us bring the right hardware.

  2. 2

    Inspect the door and frame on site

    At your property we check the door thickness, material, existing bores, and the condition of the jamb. Mid-century doors in Mission Hills can be solid wood, hollow-core, or have been refinished over the years, and each one calls for a slightly different approach.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt turns with a key outside and a thumb turn inside. A double-cylinder needs a key on both sides, which can suit doors with glass nearby but needs careful thought about emergency exit. We explain the tradeoffs so you pick what fits your household or office.

  4. 4

    Prepare the door and install the lock

    If the door has no existing deadbolt hole, we bore it cleanly to the correct size. If we are replacing a lock, we match the existing bore where possible to limit damage to the door. We then fit the bolt, cylinder, and trim, taking care with finish and alignment.

  5. 5

    Reinforce the strike and frame

    A deadbolt is only as strong as what it throws into. We set the strike plate and, where the frame allows, use longer screws that reach the framing behind the jamb, so the door resists a hard kick rather than just looking secure.

  6. 6

    Test, key, and hand over

    We operate the bolt repeatedly with the door open and closed, confirm smooth action, and hand over your keys. If you want the new deadbolt keyed to match your other exterior locks, we can set that up during the same visit.

What affects the price

  • Whether you are adding a brand-new deadbolt to a door with no bore or replacing an existing one, since fresh drilling takes more work than a swap.
  • The grade and brand of deadbolt you choose, from standard residential hardware up to higher-security graded options.
  • Door material and condition, including solid wood, hollow-core, metal, or an older door that needs careful handling to avoid damage.
  • How many doors are being done and whether you want them all keyed alike to a single key.
  • Frame and strike reinforcement, such as upgraded plates and longer screws, when the jamb is worn or weak.
  • Time of day and your location within our service area, since we are available around the clock and travel to you.

Why Mission Hills chooses us

  • Fully mobile service: the work is done at your door, with no shop visit and no need to bring the door anywhere.
  • In business since 1987, with owner and lead technician David Shar involved in the work.
  • Availability 24/7, so a door that will not lock at night or after a break-in can be addressed when it matters.
  • Attention to older doors: we work to avoid unnecessary damage on vintage and mid-century doors and finish the job cleanly.
  • Plain-language advice on single versus double cylinder and on which hardware makes sense, without pushing the most expensive option.
  • Keying options handled in the same visit, including matching new deadbolts to your existing keys.

Deadbolt Installation across Mission Hills

Mission Hills has a distinctive mix of housing, and it shapes what deadbolt work looks like here. Around the Historic Mission district and the streets near Mission San Fernando Rey de Espana and the Andres Pico Adobe, many homes are late-1940s to 1960s stucco ranch and minimal-traditional houses, with some Spanish-influenced and mid-century designs mixed in. Original hardware on these homes is often aging, and a common request is a resale-driven one: new graded deadbolt on the front door, with the exterior cylinders keyed alike so a new owner carries a single key.

In the older parts of the neighborhood, including the Dennis Park historic tract, doors tend to have character worth protecting. If a home near the adobe still has an original mortise lockset, we look at whether the lock can be repaired or sympathetically upgraded, and we add a deadbolt in a way that respects the door rather than hacking it up. We do the same for historic-adjacent properties where appearance matters as much as security.

We also serve the commercial side of Mission Hills. Along the Sepulveda Boulevard corridor and near Providence Holy Cross Medical Center, small professional and medical offices sometimes need a stronger deadbolt on a back or suite door after a staffing change. Whether you are in ZIP code 91345 off San Fernando Mission Boulevard or Brand Boulevard, or you are close to the CA-118 (Ronald Reagan Fwy), we come to you at any hour. Call (323) 997-8867.

Deadbolt Installation in Mission Hills — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door has no deadbolt bore, we drill it to the proper size, fit the bolt and strike, and reinforce the frame as needed. Many older Mission Hills homes only have a knob lock, so this is a common job. Call (323) 997-8867 to schedule.
Do I need a single-cylinder or double-cylinder deadbolt?
Single-cylinder is the usual choice for most homes since you can open it from inside without a key. Double-cylinder is sometimes considered for doors with glass nearby, but it can slow your exit in an emergency, so we talk through the tradeoffs before installing.
Will installing a deadbolt damage my older door?
We take care to keep damage to a minimum. On vintage and mid-century doors, such as those near the Andres Pico Adobe, we match existing bores where possible and work carefully so the door keeps its look.
Can you key the new deadbolt to match my other locks?
Usually yes. We can key the new deadbolt to your existing exterior locks so one key works for all of them, which is popular for resale and move-ins.
Do you offer deadbolt installation at night or on weekends?
Yes. We are available 24/7 and fully mobile, so we come to your Mission Hills address any time. Call (323) 997-8867 and we will take it from there.
Is a deadbolt enough to make my door secure?
A good deadbolt helps a lot, but it is only as strong as the door and frame around it. That is why we check the jamb and strike, and reinforce them where the frame allows.
Do you do deadbolts for offices and medical suites?
Yes. We install and replace deadbolts for small professional and medical offices, including those along Sepulveda Boulevard, and can handle rekeying or a simple master-key setup after staff changes.
Do I need to come to a shop?
No. Crenshaw Lock Company is mobile only, with no storefront. We bring everything needed to your door anywhere in Mission Hills, including ZIP code 91345.
