A deadbolt is the single most useful upgrade you can make to an exterior door, and in Studio City the doors that need one vary a lot. North of Ventura Boulevard, many 1940s and 50s ranch and traditional homes still carry original or mid-century hardware: a worn knob lock, maybe an old deadbolt with a loose cylinder, or a door that has been repainted so many times the bolt barely lines up. Those doors usually benefit from a fresh, properly fitted deadbolt rather than a quick swap.

Crenshaw Lock Company has served Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has seen just about every way a deadbolt can be installed badly. We are fully mobile, so there is no shop to visit. We come to your house, condo, or office, look at the door and frame, and install the hardware in place. We are available around the clock, which matters when a break-in attempt, a lost key, or a move-in date puts a lock on the urgent list.

This page covers how a deadbolt installation works, what changes the cost, how single- and double-cylinder options differ, and what Studio City homeowners, condo owners, and landlords should think about before choosing. If you are not sure what your door needs, call (323) 997-8867 and describe it. We will tell you honestly whether you need a new deadbolt, a replacement, or just an adjustment.

How it works in Studio City

  1. 1

    Talk through the door

    We start with a call. Tell us the door type, whether it already has a deadbolt, and what prompted the change, such as a move, a break-in attempt, or a worn lock. That helps us bring the right hardware.

  2. 2

    Inspect the door and frame

    On arrival we check door thickness, material, existing bore holes, and the strike plate and frame. A strong deadbolt in a weak frame is only half a fix, so we look at both.

  3. 3

    Choose the cylinder and grade

    We explain single-cylinder versus double-cylinder, and the available hardware grades and finishes. Single-cylinder turns with a thumbturn inside; double-cylinder needs a key on both sides, which has fire-egress tradeoffs we will discuss plainly.

  4. 4

    Install and align

    We fit the deadbolt, drilling or adjusting the bore only if needed, and set the strike so the bolt throws fully into the frame. Where it makes sense, we recommend a longer strike plate with longer screws for added resistance.

  5. 5

    Test and key it

    We cycle the lock repeatedly with the door open and closed, confirm smooth operation, and can key it to match other locks on the property so you carry fewer keys.

  6. 6

    Walk through and leave you set

    You get all keys, a quick explanation of how the lock works, and any notes on other doors that deserve attention.

What affects the price

  • Whether this is a new installation requiring fresh holes or a replacement of an existing deadbolt that fits the current bore
  • Single-cylinder versus double-cylinder, and the grade and brand of hardware you choose
  • Door material and condition, since solid wood, metal, and older repainted doors can need different prep
  • Frame and strike reinforcement, such as upgraded strike plates or repairs to a worn or split door jamb
  • Number of doors and whether locks are keyed alike to work with existing keys
  • Time of day and urgency of the visit, since we are available 24/7 and after-hours service differs from a scheduled one

Why Studio City chooses us

  • Fully mobile service: we come to your Studio City door instead of asking you to bring anything to a storefront, because we do not operate one
  • In business since 1987, with owner David Shar leading the work rather than handing it off blindly
  • We look at the frame and strike, not just the lock, because a deadbolt is only as strong as what it bolts into
  • Straight advice on single versus double cylinder, including the egress and safety tradeoffs, instead of upselling the one that costs more
  • Experience across older ranch hardware, condo complexes, and newer smart-lock and multipoint setups, so we are not guessing at unfamiliar doors
  • Available 24/7, so a break-in aftermath or lost-key emergency does not have to wait for business hours

Deadbolt Installation across Studio City

Studio City has several distinct kinds of doors. In Colfax Meadows and the flats around Colfax Avenue, many homes date to the 1940s and 50s and still have original or mid-century hardware, so a new deadbolt often means matching an old bore and tightening up a frame that has settled over decades. In the Silver Triangle and the many 1960s-80s condo and apartment buildings throughout 91604 and 91602, landlords and HOA-managed owners often want deadbolts keyed alike or matched to a building's existing system.

In the southern hillsides toward Fryman Canyon, Wilacre Park, and Laurel Canyon, the mix shifts to mid-century moderns and newer gated contemporary estates with smart locks, driveway gates, and intercoms. There, a mechanical deadbolt is often a backup to electronics, and a battery failure can leave a homeowner outside. We can service a smart deadbolt's mechanical override and battery, and we can add or upgrade a conventional deadbolt as a dependable fallback. After an attempted break-in, we also look at front-door multipoint locks and gate hardware, which is the kind of work an estate near Fryman Canyon may need.

Along Ventura Boulevard, aluminum-storefront shops and restaurants have their own needs, and a realtor with a listing there may want a lock rekeyed and a lockbox added between showings. Whether you are in 91607 near Radford Studio Center, in 91614 near Tujunga Village, or off Coldwater Canyon Avenue, we travel the 101, Ventura Blvd, and the canyon roads to reach you, any hour.

Deadbolt Installation in Studio City — FAQs

Do you install deadbolts in Studio City at night or on weekends?
Yes. We are available 24/7 and fully mobile, so we can come to your home or business at any hour. Call (323) 997-8867 and describe the door.
Should I choose a single-cylinder or double-cylinder deadbolt?
Single-cylinder is the usual choice for most homes because it has a thumbturn inside, so you can leave quickly in an emergency. Double-cylinder needs a key on both sides and can make sense next to glass, but it can slow exit in a fire, so we talk through the tradeoffs first.
My Studio City home is a 1950s ranch with an old knob lock. Can you add a deadbolt?
Usually yes. We check door thickness and condition, add a bore if needed, and fit the deadbolt with a properly aligned strike. We also look at the frame, since older jambs can be worn or split.
My smart deadbolt died and I am locked out. Can you help?
We can help with the mechanical override, battery, and lock service on many smart deadbolts. Call (323) 997-8867 and tell us the brand and model if you know it. We can also add a conventional deadbolt as a reliable backup.
Can you key a new deadbolt to match my other locks?
In many cases, yes. We can key the new deadbolt alike with existing locks on the property so you use fewer keys. It depends on the brands involved, and we will tell you what is possible.
What affects the cost of installing a deadbolt?
The main factors are new installation versus replacement, the type and grade of deadbolt, door and frame condition, any strike or jamb reinforcement, the number of doors, and the time of the visit. We explain the options before any work starts.
Do you work on condos and apartments, or only houses?
Both. Studio City has many 1960s-80s condo and apartment buildings, and we install deadbolts for owners and landlords. Check your lease or HOA rules first, since some buildings control which locks you can change.
Do I need to come to a shop to pick out a deadbolt?
No. We are mobile only and have no storefront. We bring the hardware to you, install it at your door, and you can reach us anytime at (323) 997-8867.
