Why do West Hollywood residents need a deadbolt installed or replaced?
A deadbolt is the one lock on most doors that does real work against force. The spring latch in a standard knob or lever set holds the door shut, but it is not built to resist a pry bar or a hard shoulder. A deadbolt throws a solid steel bolt into the door frame, and when it is installed properly it takes far more effort to defeat. The key phrase is installed properly, because a good bolt in a badly drilled door is not much better than no bolt at all.
In West Hollywood the calls we get tend to fall into a few groups. A tenant moves into a unit with no deadbolt, or with a worn one that sticks and wobbles. A homeowner wants a second lock on a side or back door. A landlord upgrades a building after hearing about a break-in nearby. Or someone finds that the deadbolt they already have has a loose cylinder, a bolt that does not fully extend, or a thumb-turn that grinds. Each of those is a deadbolt installation or deadbolt replacement job, and each starts with looking at the door rather than guessing.
This page covers new deadbolt installation, deadbolt replacement, and double cylinder deadbolt installation. If your lock works fine and the only problem is that you do not know who has keys, that is a different and often lighter-cost job, and we explain it under lock rekeying.
What is the difference between a single-cylinder and a double-cylinder deadbolt?
A single-cylinder deadbolt has a keyway on the outside and a thumb-turn on the inside. You lock and unlock from inside by hand, with no key. It is the standard choice for homes and apartments, and it is what we install most often.
A double-cylinder deadbolt has a keyway on both sides, so you need a key to open it from inside as well. People ask for one when a door has glass in it or right beside it. If someone breaks the glass, they cannot simply reach through and turn a thumb-turn. The tradeoff is real, though. In a fire or any other emergency, you have to find a key to get out. That is why many building and fire rules restrict double-cylinder locks on residential exit doors. The rules differ depending on the building type and how the door is used, so we do not install one blindly.
Before a double cylinder deadbolt installation, we ask where the door leads, whether it is a required way out of the unit, what your landlord or building manager allows, and whether something simpler solves the same worry. Sometimes a single-cylinder bolt mounted with some distance from the glass, or a different door, does the job without the exit problem. If you do go with a double cylinder, keep a key near the door where it cannot be reached from outside, and make sure everyone in the home knows where it is.

Call (213) 577-1366How does Wilshire Lock & Key install a deadbolt?
Every door is a little different, so we do not run a script. This is the sequence we follow on nearly every job, and it is the same whether we are doing a new installation or a replacement.
- Look at the door and frame. We check the material, the thickness, the edge, any existing holes, and the condition of the jamb. Solid wood, metal, and older doors each behave differently under a drill.
- Confirm the measurements. Most residential deadbolts need a 2-1/8 inch hole through the face of the door, a 1 inch hole into the edge, and the right backset, usually 2-3/8 or 2-3/4 inches. If an old lock left holes behind, we measure and match them instead of forcing a lock that does not fit.
- Drill or adapt. If the door has no bore, we use a proper hole saw and a door-installation jig so the holes come out square and centered. If an existing hole is oversized or damaged, we reinforce it before fitting anything.
- Cut the edge. The faceplate on the door edge is recessed so it sits flush and the door does not bind.
- Fit the bolt and cylinders. We connect the tailpiece to the thumb-turn or to the second cylinder, and tighten the through-screws evenly without over-tightening, which can make the bolt drag.
- Set the strike. The strike plate in the frame is where most weak installs fail. We recess it cleanly, drill the bolt hole deep enough, and use long screws that bite into the framing behind the jamb, not just the thin jamb itself.
- Test it properly. We run the bolt with the door open, then closed, over and over. It should extend fully with no lifting, pulling, or pushing on the door. If it rubs, we correct the alignment before we leave.
- Hand over the keys and show you how everything works. We clean up the shavings and leave the door finished.
When is deadbolt replacement the right call, and when is rekeying or repair enough?
Not every troublesome deadbolt needs to be swapped out. We would rather tell you that than sell you hardware you do not need. The signs below usually point toward replacement, and our lock replacement work follows the same door-first approach.
- The bolt does not fully extend, or only extends when you lift or push the door.
- The cylinder is loose or spins in the door.
- The key turns hard even after the lock has been cleaned and lubricated.
- The internals are worn from years of use, and the key feels sloppy in the keyway.
- The lock was damaged in a break-in attempt, even if it still seems to work.
- You want to move up to a sturdier grade or a more pick-resistant cylinder.
- You are a tenant or owner who has no idea how many copies of the old key exist.

Call (213) 577-1366What affects the cost of deadbolt installation in West Hollywood?
We do not publish numbers on this page because the honest answer depends on the door, not on a menu. What we can do is tell you exactly what moves the cost up or down, so nothing surprises you.
If you describe the door when you call (213) 577-1366, we can walk through these factors with you before anyone drives out. A replacement on a door that already has the right holes is generally the more economical route. A fresh installation on a door that has never had a bore, or one that needs repair work first, takes more time and materials.
- New installation versus replacement. Drilling a fresh door is more work than swapping into existing holes.
- Door material and condition. Solid wood, metal, and older doors with prior damage each take different tools and care.
- Deadbolt grade and brand. Basic hardware and heavier-duty or pick-resistant models are priced differently.
- Single versus double cylinder. Double-cylinder hardware is more specialized.
- Strike and frame work. Reinforcing a weak jamb or fitting a longer strike adds labor and parts.
- Number of doors and keying. Several doors keyed alike takes more planning than a single lock.
- Hardware you supply. If you already bought a deadbolt, we will install it, but we will tell you honestly if it is a poor fit for the door.
- Time of day and travel. After-hours calls and distance can affect the overall cost.
Which grade and keying setup makes sense for your door?
Residential deadbolts are commonly sorted into three grades under the ANSI/BHMA system, with Grade 1 tested for the heaviest use and force, and Grade 3 for lighter duty. For an apartment entry or a house front door, a Grade 1 or Grade 2 bolt is generally worth considering, because the entry door takes the most abuse. For a lightly used interior or secondary door, a lower grade may be fine.
Grade is only part of it. If you want keys that cannot be casually copied at a hardware store, or a cylinder designed to resist picking and drilling, look at our high-security locks options. If you want one key for the front door, the back door, and a side gate, we can key them alike, which means one key works on all of them.
If you are leaning toward keypads or phone-based entry, that is a separate installation with its own considerations, and we cover it under smart lock installation. Many people keep a mechanical deadbolt on the door and add a smart lock only where it makes sense.

Call (213) 577-1366What do deadbolts look like in West Hollywood's courtyard buildings, condos, and houses?
West Hollywood is one of the densest small cities in the county, and the housing mix shapes almost every deadbolt job here. Much of the stock is 1920s and 1930s courtyard apartments, mid-century dingbats, and newer condominium buildings, and the large majority of residents rent. Single-family streets are clustered in West Hollywood West and the Norma Triangle. Multifamily buildings typically have controlled-access entries, buzzer and intercom systems, and shared mailbox banks, which means the unit door is often the one lock a tenant actually controls.
The older courtyard buildings are where we slow down. Many keep their original wood doors and vintage locksets, and those doors can be thin, painted over several times, or already patched around old holes. Before we drill, we check whether the wood can take a standard bore, whether an older mortise lock is in the way, and whether the frame can hold a long strike screw. If a door is too fragile for what you want, we say so and talk through the alternatives, which may mean reinforcement or a different hardware choice.
Renters should check their lease before anything is changed. Many landlords want to approve or supply the hardware, and some keep a key on file. If you manage units, our page for landlords and property managers explains how we handle multi-door work and key records. If you are already locked out of a unit in a controlled-access building off Santa Monica Boulevard, that is an apartment lockout first and a deadbolt job second.
Climate adds little here. West Hollywood sits in the mild mid-basin zone, so hardware wear is modest. Strong summer sun on south-facing entries can dry and fade door finishes, which is mostly a reason to choose a hardware finish that matches the door and to be careful with paint and trim when we cut the edge.
Where do we install deadbolts around West Hollywood?
We work across the whole city, including the ZIP codes 90069, 90046, and 90048. A few typical situations show how the work differs from one part of town to the next.
In the renter-heavy Eastside, the most common request is a tenant who has just moved in and wants a solid deadbolt checked, replaced, or rekeyed before the first night. If the unit has no deadbolt at all, we measure the door and tell you whether a new installation is practical. In the Santa Monica Boulevard and Rainbow District area, many doors open into controlled-access buildings, so we pay attention to how the lock lines up with an intercom-driven entry and the building's rules.
In the Norma Triangle and West Hollywood West, where single-family houses are more common, the jobs lean toward front doors, side doors, and back doors. People often want a second deadbolt on a door that has only a knob lock, or a replacement for a bolt that came with the house and has loosened over the years. In the Sunset Strip area, which is also part of 90069, we see residential buildings mixed in with nightlife, and homeowners and tenants there tend to care about solid frames and tight strikes. Businesses on the Strip, along Melrose Avenue, and in the Design District need commercial door hardware instead, and that is handled as separate commercial work.
West Hollywood is about 7 miles from our Westwood storefront, and our mobile locksmith vans carry the tools and common deadbolt hardware to do most installations on site.

Call (213) 577-1366Why call Wilshire Lock & Key?
We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans on the road. When you call, you reach the same company that sends the technician.

One more thing worth knowing. California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith you are considering for their license number and check it with the state before you let anyone work on your door.
What should you have ready, and what if it is urgent?
If you can, tell us a few things when you call: which door it is, whether it already has a deadbolt, whether the door is wood or metal, and whether you are a tenant or an owner. A quick photo of the door edge and the frame can help too. If you plan to buy your own hardware, call first so we can tell you what will fit.
If a break-in has just damaged your door or frame, or you cannot secure the unit tonight, call us right away. Our emergency locksmith service is built for those situations, and we will tell you what can be secured immediately and what is better finished in daylight.

Frequently asked questions
Can you install a deadbolt on a door that does not have one?
Usually yes. It depends on the door's thickness, material, and condition. Solid wood and most metal doors take a standard bore well. Very thin or hollow doors may need reinforcement or a different solution, and we will say so before we drill.
How long does a deadbolt installation take?
It varies with the door. Replacing a bolt into holes that already fit is quicker than drilling a new door, and extra frame or strike work adds time. Most installations are finished in a single visit, and we do not rush the alignment step.
Do I need my landlord's permission to change my deadbolt?
Check your lease first. Many landlords want to approve or supply hardware, and some require a key on file. Ask before any change, and keep the original hardware in case you need to put it back when you move out.
Are double-cylinder deadbolts allowed in an apartment?
It depends on the building, the door, and the rules that apply to it. Because a double cylinder needs a key to exit, many residential exit doors restrict them for safety reasons. Ask your landlord or building manager, and we will talk through whether a single cylinder is the safer fit.
Can the new deadbolt use the same key as my existing lock?
Often, if the brands and keyways are compatible. We confirm that in person with the lock in hand. If it cannot be matched, we can key the new deadbolt to a single new key or key several doors alike.
Will drilling damage my vintage wood door?
Careful work should not. We use a proper hole saw and jig, check for old holes and thin spots first, and tell you beforehand if the door is too fragile for what you want. The visible hardware on an older door will look different, so we will talk through finish and placement.
Do you install smart deadbolts as well?
Yes. Electronic and keypad deadbolts are covered as a separate smart lock installation service. Tell us what you want, and we will help decide whether a traditional deadbolt, a smart lock, or both suits the door.
Is a deadbolt enough to secure my door?
A good deadbolt only works as well as the door and frame around it. A short strike screw into thin jamb wood is a weak point, as are hinges, glass, and nearby windows. When we install, we check the strike and frame so the whole entry holds up.
Can you install a deadbolt late at night or on a weekend?
Yes. We answer the phone 24 hours a day, 7 days a week, including holidays, at (213) 577-1366. If the work is not urgent, we will say so, but we are available when you need us.
