What does deadbolt installation involve on a Ladera Heights home?
A deadbolt is the lock that does the real work on an exterior door. The spring latch in an ordinary knob holds a door shut against the breeze, but it was never meant to resist a pry bar or a thin piece of plastic slid past the latch. A deadbolt throws a solid steel bolt, usually about an inch long, into the door frame, and that bolt only moves when a key or a thumb turn moves it. Putting one in properly is less about the lock itself and more about how the lock meets the door and the frame around it.
Most deadbolt calls fall into a few groups. Some doors have no deadbolt at all. Some side or garage doors have only a knob lock. Some existing deadbolts have worn out, started to stick, or lost their keys. And some doors have already been forced and need the damage dealt with before any new hardware goes on. Each one is a different job. A door that never had a deadbolt needs new holes drilled. A straight swap usually reuses the holes already there. A damaged door may need its edge or jamb repaired first, because a strong lock in a split frame is not worth much.
This page covers deadbolt installation, deadbolt replacement, and double cylinder deadbolt installation for homes in Ladera Heights. If your lock still works and you only need different keys, that is a different and often lighter-cost job, covered under lock rekeying in Ladera Heights.
Should you choose a single-cylinder or a double cylinder deadbolt?
A single-cylinder deadbolt has a keyed cylinder on the outside and a thumb turn on the inside. It is the standard choice for nearly every front door, and it lets anyone in the house get out quickly without looking for a key. A double-cylinder deadbolt takes a key on both sides, so the inside needs a key to open as well.
People ask for double cylinder deadbolt installation for one main reason: glass. If a door has a window in it, or a sidelight close enough that someone could break the pane and reach in, a thumb turn is within a burglar's reach. A keyed inside cylinder removes that weakness. The tradeoff is real, though. In a fire or any other emergency, somebody has to find a key to get out. Many fire and building codes limit or prohibit double-cylinder locks on residential doors that serve as an exit, and the rules vary by jurisdiction and building type. We talk this through with you before we put one on a door, and we will tell you plainly when we think single-cylinder is the better answer.
Here is how we usually sort it out:
- Solid door with no glass near the lock: a single-cylinder deadbolt is almost always the right choice.
- Glass within arm's reach of the thumb turn: consider reinforcing or replacing the glass, or using a double-cylinder only on a door that is not your main way out.
- Children, older adults, or anyone who might panic in an emergency in the home: stay with single-cylinder.
- Rented or shared property: check your lease and any association rules before changing the lock type.

Call (213) 577-1366How do we install a deadbolt, step by step?
The work is not complicated, but small errors show up later as a bolt that rubs, a key that binds, or a door that only locks if you lift it. Here is the order we follow on a typical residential door.
- Look at the door and frame. We check the door's thickness and material (wood, steel, or fiberglass), the condition of the edge, whether holes already exist, and how the door sits in the frame. Most residential doors take a standard bore of about 2-1/8 inches through the face and 1 inch into the edge, with a backset of either 2-3/8 or 2-3/4 inches, but we measure instead of assuming.
- Pick the hardware with you. We go over single or double cylinder, the grade of the lock, the finish, and whether you want keys that match your other locks.
- Mark and drill. On a new installation we use a template and a hole saw with a guide so the holes are square, centered, and on the same line as the knob or handle. Wood doors are drilled carefully to avoid splintering the face, and steel and fiberglass doors get the right bits for the material.
- Fit the bolt assembly. The latch goes into the edge bore, and the faceplate is set flush so it does not catch or leave a gap.
- Mount the cylinder and thumb turn, or the second cylinder for a double-cylinder lock. The two halves are joined through the door and tightened so nothing wobbles.
- Install the strike plate. This is the step many quick installs skip. We set the strike in the jamb, deepen the bolt hole, and use long screws that bite into the framing behind the jamb, not just the thin trim, because that is what actually resists a kick.
- Test and hand over. We cycle the lock many times with the door open and closed, check that the bolt extends fully without rubbing, confirm the door does not need to be lifted or pulled to lock, and give you the keys and a quick walkthrough.
How much does deadbolt installation cost in Ladera Heights?
We do not quote a number on a web page because the same phrase, deadbolt installation, covers very different jobs. What we can do is tell you what moves the price up or down, so the quote you get on the phone makes sense.
Giving you the lighter-cost option is part of the job. If your existing deadbolt is sound and only the keys are the concern, rekeying is usually the more economical route. If the lock is worn or the door is out of alignment, a new lock on its own will not solve it, and we will say so.
- New installation or swap: a door that has never had a deadbolt needs drilling and fitting, while a replacement that reuses existing holes is usually simpler.
- The lock you choose: basic residential grades, higher-grade hardware, high-security cylinders, and smart deadbolts sit at very different levels.
- Single or double cylinder: the hardware differs, and the second cylinder adds parts and setup.
- Door condition: a cracked edge, a loose jamb, a sagging door, or old filled holes can add repair work before the lock goes on.
- Door material: steel and fiberglass doors take more care and different tooling than solid wood.
- Number of doors and key matching: doing several doors together, with all of them keyed alike, changes the work involved.
- Timing and location: an after-hours call or a longer trip is priced differently from a scheduled daytime visit.

Call (213) 577-1366When is deadbolt replacement better than a new installation?
Deadbolt replacement is the right call when there is already a deadbolt but it is worn, damaged, outdated, or you do not know who holds a key to it. The existing holes are often reusable, which keeps the job straightforward. We still check the strike plate and jamb, because a lot of replacement jobs reveal that the original problem was the alignment, not the lock.
Signs it is time to replace a deadbolt include:
- The key sticks, turns hard, or only works with jiggling.
- The bolt does not fully extend, or you have to push or lift the door to lock it.
- The lock wobbles on the door or the thumb turn spins loosely.
- You moved in and have no idea how many copies of the old key exist.
- A key broke off or the cylinder shows signs of tampering or a forced attempt.
- You want better hardware than the builder-grade lock that came with the house.
What do deadbolt jobs look like in Ladera Heights?
Ladera Heights is mostly single-family homes built out in the 1940s through the 1960s, with mid-century ranch, traditional, and contemporary houses on well-kept lots. Many of those homes still carry original-era locksets and garage side-door hardware. In Upper Ladera Heights, Lower Ladera Heights, and the Ladera Center area around 90056, that means a lot of our deadbolt work starts with a door that has been lived in for decades. Older doors can have been repainted many times, re-hung, or drilled for earlier hardware, so we check the existing holes and the condition of the edge before deciding how to proceed.
One of the most common requests on these lots is the garage side door and the yard gate. A garage side door often has only a knob lock, and it is a door people forget about even though it leads into the house or the garage. Adding a deadbolt there is a simple upgrade that closes an easy weak point. For gates, a different kind of lock is usually the right fit, and our page on gate lock repair covers that side of it.
Near the Fox Hills border there is some condominium and townhome stock, and deadbolt jobs there come with extra questions. Who owns the lock on the front door, you or the association? Are there rules about finish or hardware type? We ask before we start so you do not have to undo anything later.
If you are in one of the view homes above Kenneth Hahn State Recreation Area and want a keypad or app-controlled lock, that is a smart deadbolt, and we handle it under smart lock installation. The climate here is mild. The elevated ground near the Baldwin Hills brings steady breezes and some marine-layer mornings, but the effect on door hardware is modest, so you can choose a deadbolt based on security and appearance, not on weathering. Our base is roughly 10 miles away, and our mobile vans cover Ladera Heights the same way they cover the rest of our service area.

Call (213) 577-1366What should you look for in a deadbolt itself?
Not all deadbolts are the same, and the box does not always make that clear. A few things matter more than the brand name on the front.
Grade is a rating from the American National Standards Institute and the Builders Hardware Manufacturers Association. Grade 1 is the most durable and is built for heavy use, Grade 2 sits in the middle, and Grade 3 is the lightest residential level. For an exterior front door, we generally lean toward the higher grades.
Beyond grade, we look at the bolt itself and how it is protected. A bolt about an inch long that reaches well into the frame is better than a short one. A hardened steel insert helps resist sawing, and a cylinder built to resist picking and bumping adds protection against quieter attacks. The strike plate and its screws matter just as much as the lock, which is why we install them the way we do.
If your concern is more serious than a standard deadbolt, such as a door that has been targeted before or a home with valuables, we can talk about stepping up to restricted-key cylinders and reinforced strikes. That is covered in more depth on our page about high-security locks.
Why call Wilshire Lock & Key for a deadbolt?
We have been in business since 1987, and deadbolts are everyday work for us. We run a storefront at 10740 Wilshire Blvd in Westwood along with mobile service vans, so you can reach a real shop with real stock, not just a phone number. We are one company from the call to the finished door, with no dispatch middleman passing your job to someone you have never heard of. David, the owner and lead technician, oversees the work.
You should also ask any locksmith about licensing. California requires locksmith companies to hold a BSIS LCO license, and a reputable company will not mind being asked for it. It is a fair question and it is worth asking before anyone starts drilling your door.

What if you need a deadbolt tonight?
Sometimes a deadbolt is not a planned upgrade. A break-in, a forced door, or a lock that fails at the wrong moment can mean you need the house secured right now. We answer around the clock, and our emergency locksmith service covers those situations. If you are also locked out, the house lockout page explains how we get you back in without damaging the door when possible.
For planned work, such as adding deadbolts to a whole house, our mobile locksmith service comes to your driveway with the hardware and tools to finish the job on site. Call (213) 577-1366 and tell us the door type, whether there is glass nearby, and whether a deadbolt is already there. That is usually enough for us to prepare properly.
Frequently asked questions
Can you install a deadbolt on a door that never had one?
Yes. We drill a new bore in the face and edge of the door using a template and a hole saw, fit the bolt, and install a reinforced strike plate in the jamb. Door material and thickness matter, so we check those first. Very thin or badly damaged doors may need repair or replacement before a deadbolt is worthwhile.
Is a double cylinder deadbolt legal on a house in Ladera Heights?
It depends on the door and the rules that apply to your property. Many fire and building codes restrict double-cylinder locks on doors used as an exit, and requirements vary by jurisdiction and building type. We will talk through the safety tradeoff with you and recommend single-cylinder if that is the safer, simpler fit for your door.
Do you charge by the door or by the job?
We cannot give a number without knowing what the door needs. The price depends on whether it is a new install or a replacement, the lock you pick, the door material, any repair to the door or frame, and the time of the call. Call (213) 577-1366, describe the door, and we will explain what applies.
How long does it take to replace a deadbolt?
A straightforward replacement into existing holes is a quick job. A new installation takes longer because of drilling and fitting, and a door that needs repair first takes longer still. We would rather do it properly than rush, since a poorly aligned deadbolt will bother you every day.
Can you make all my deadbolts use the same key?
Yes, we can key new deadbolts alike so one key opens your front door, garage side door, and others. We can also match them to an existing lock in many cases. If your current locks only need new keys, rekeying them may be the more economical route.
My deadbolt does not fully extend unless I lift the door. Do I need a new one?
Not necessarily. That symptom usually points to the door sagging or the strike plate sitting out of line with the bolt. We check the hinges, the strike, and the bolt hole first. If the lock itself is worn, we replace it, but often the fix is an alignment.
Do you install smart deadbolts?
Yes. Keypad and app-controlled deadbolts need the same careful door preparation as a regular one, plus attention to power and setup. We install them as a separate service, and we can help you decide whether a smart lock or a standard deadbolt suits your door.
Will a new deadbolt fit my older door?
Usually, yes. Most standard deadbolts fit common bore sizes, but older doors can have unusual holes, heavy paint buildup, or earlier repairs. We measure the door and look at the edge before we choose hardware, so we can tell you in advance whether it fits cleanly or needs some adjustment.
Can you come out after hours to secure my door?
Yes. Our phone is answered 24 hours a day, 7 days a week at (213) 577-1366. If your door was forced or will not lock, tell us what happened, and we will explain what we can do on site to make it secure.
