Deadbolt Installation Cost in Los Angeles: What You’ll Actually Pay in 2024
Deadbolt installation in Los Angeles typically runs $140-$320 for a standard single-cylinder job, with most homeowners in neighborhoods like Silver Lake and Mar Vista landing around $190-$240 including hardware. If you’re dealing with a shifted door frame after a soft-story seismic retrofit or need a smart deadbolt tied into a new ADU key system, the price can climb toward $380-$450. Call (877) 664-8139 and we’ll quote your exact job flat before we drive - the number on the phone matches the number on the invoice.
We’ve installed deadbolts across Los Angeles County for over 42 years. The price swings aren’t random. They track to three things: what your door and frame are actually doing, what grade of lock you want, and whether the job is straightforward or needs problem-solving. Below is what we’ve charged on real jobs this past year, with the local wrinkles that move the number.

Why Los Angeles Deadbolt Jobs Cost What They Do
The Housing Stock Determines Half the Labor
Los Angeles doesn’t have one kind of door. We’ve got 1920s-1940s Craftsman bungalows in Highland Park and Los Feliz with original mortise locksets that need careful conversion. The wood is dense, the backsets aren’t always standard, and we’ve machined more than a few custom strike plates to get a clean throw. Those jobs run toward the higher end of our range, but they get done right - no chewing up the jamb with a hole saw and hoping.
Then there are the dingbat apartments. Maybe 30,000-50,000 of them citywide, built 1950s-1970s, running aging master-key systems. We rekey these constantly as tenants cycle through. Installing a new deadbolt on a dingbat unit often means working around a master-keyed cylinder, coordinating with the property manager, and sometimes discovering the previous installer used hardware that doesn’t match the system. That coordination takes time. We quote it flat so you’re not watching a meter run.
The Seismic Retrofit Aftermath
Here’s a Los Angeles-specific cost driver you won’t find on generic locksmith sites: the mandatory soft-story seismic retrofit ordinance. Roughly 13,500 buildings fell under it, with most deadlines hitting 2019-2022. The structural work on ground floors shifted door frames out of plumb across Koreatown, Hollywood, and the Fairfax corridor. A deadbolt that threw cleanly before retrofit now binds, or the strike plate sits a quarter-inch off. We’ve spent three years fixing these - not replacing the lock, but realigning the frame, relocating strikes, sometimes shimming the jamb. It’s skilled work, and it adds $120-$220 to a standard install. We always check frame plumb before we quote; it’s why our jobs don’t end with a callback.
Salt Air and the Marine Layer
Along the western corridor - Venice, Mar Vista, Playa del Rey, Westchester - the marine layer and coastal salt air corrode lock cylinders faster than inland ZIP codes just ten miles east. We see pitted deadbolts out there that should have lasted fifteen years but failed in eight. When we install in these neighborhoods, we recommend Baldwin or certain Yale grades with better corrosion resistance, or we apply a protective treatment to standard hardware. That hardware choice moves the price, but it also means you’re not calling us back in three years.
ADU Lock Systems: A Volume Like Nowhere Else
Los Angeles has issued more ADU permits than any other U.S. city - over 20,000 per year at peak. Every ADU needs its own keying, and most owners want it separate from the main house. We regularly install deadbolts on ADUs with smart-lock integration so the owner can grant temporary codes to guests or contractors. That setup - new deadbolt, programming, testing, and teaching the homeowner - runs toward our higher range, but it’s become routine for us in a way it simply isn’t in other markets.
Common Scenarios We See in Los Angeles
These aren’t hypotheticals. These are jobs we did last month.
- The Silver Lake bungalow with the sticking deadbolt. Santa Ana winds hit, humidity dropped, the 1930s door frame shrank. The deadbolt wouldn’t throw fully. We realigned the strike, added a reinforcement plate, and installed a new Kwikset SmartKey deadbolt the owner can rekey himself when his tenant changes. Total: $235.
- The Koreatown soft-story retrofit. Frame shifted during structural work. Deadbolt bound so hard the owner snapped a key. We relocated the strike, shimmed the jamb, and installed a Medeco high-security cylinder. Total: $395.
- The Mar Vista ADU. Owner wanted separate keying from main house, Yale Assure Lock with WiFi for Airbnb guests. We installed, programmed, and walked her through the app. Total: $340.
- The Echo Park Craftsman conversion. Original mortise lockset, owner wanted a modern deadbolt without destroying the vintage door. We sourced a compatible trim and machined a custom strike. Total: $310.

FAQs
Most standard deadbolt installations in Los Angeles run $140-$320, with the typical homeowner paying $190-$240 including hardware. Jobs involving frame realignment after seismic retrofit, ADU separate key systems, or high-security smart locks can reach $380-$450. Call (877) 664-8139 for a flat quote on your specific door - estimates are free.
Repairing a sticking or corroded deadbolt usually costs $85-$150, but if the cylinder is worn or the internal mechanism is failing, a new install at $140-$195 is often the better value. In coastal Los Angeles neighborhoods where salt air accelerates corrosion, we generally recommend replacement if the deadbolt is over ten years old. We will tell you straight which makes sense for your door.
Yes. We carry Kwikset, Medeco, Yale, and Baldwin deadbolts on every truck, and we schedule same-day appointments across Los Angeles County when you call before early afternoon. Emergency installs after a break-in or lockout get priority. Call (877) 664-8139 - a live person answers, and we will be there when we say.
Double-cylinder deadbolts, which require a key on both sides, add security if you have glass near the door that could be broken to reach inside. They cost $180-$260 installed. However, Los Angeles fire codes restrict them on certain exit doors, and they can trap occupants during an emergency. We assess your specific door, window placement, and code requirements before recommending one.
