What does deadbolt installation involve in Palos Verdes Estates?
A deadbolt is the lock that does the real work on an exterior door. The latch in your knob or lever only keeps the door shut; the bolt is what resists a shoulder, a pry bar or a kick. Installing one means either fitting a new bolt on a door that has none, or replacing a worn, loose or badly aligned one so it throws cleanly into the frame.
Most calls fall into a few groups. A front or side door never had a deadbolt. A bolt sticks, spins loose, or no longer lines up because the door has shifted over the years. A new owner wants something solid before moving in. Or a homeowner wants a keyed-both-sides deadbolt beside a glass panel. All of these are deadbolt installation or deadbolt replacement, but each starts from a different door, and the door decides more of the job than the lock does.
Wilshire Lock & Key has been doing this work since 1987. David oversees it, and our mobile vans carry the bolts, cylinders, strike plates and boring tools to finish the job at your door instead of asking you to bring the door to us. If you want the wider picture of what we do for homes, see our residential locksmith service.
Single or double cylinder: when does double cylinder deadbolt installation make sense?
A single-cylinder deadbolt takes a key on the outside and has a thumb turn on the inside. It is the right choice for most doors, because anyone inside can get out in a second without looking for a key. Most front doors we work on get this type.
A double-cylinder deadbolt takes a key on both sides. Double cylinder deadbolt installation makes sense mainly when there is glass within arm's reach of the inside thumb turn, such as a sidelight, a glazed panel in the door, or a window right beside the frame. With no thumb turn, a person who breaks the glass has nothing to reach and turn.
The trade-off is real. In a fire or any emergency, a keyed inside cylinder means you need a key to get out. Some building and fire rules, and some rental agreements, limit keyed-both-sides locks on certain doors, so we talk that through before we install one. If you do choose it, the usual practice is to keep a key near the door but out of reach from the glass, and to make sure everyone in the house knows where it is.
- Single cylinder: the better fit for solid doors and nearly all entry doors.
- Double cylinder: for doors with glass close to the thumb turn, when you accept the key-to-exit trade-off.
- Neither: if the weak point is a thin door, a split frame or a short strike screw, we will say so, because hardware alone will not fix that.

Call (213) 577-1366How we install a deadbolt, step by step
Here is how a typical visit goes. The order stays the same whether the job is a new installation or a replacement, though a replacement often skips the drilling.
- You call (213) 577-1366. We ask about the door material and thickness, whether it already has a bolt hole, whether you want single or double cylinder, and whether the new lock should be keyed to match anything else.
- A van comes to the address. Before any drilling, we look at the door, the frame, the hinges and how the door closes. A lock cannot be aligned well on a door that is sagging or rubbing.
- For a new installation, we mark the height and backset, then bore the large cross hole through the face and the smaller edge hole for the bolt, using a guide so both holes meet square. For a replacement, we measure the existing holes and confirm the new bolt fits them, and fill or reinforce any hole that is worn oversize.
- We fit the bolt and cylinder, then set the strike plate. The strike pocket is cut to depth so the plate sits flush, and we use long screws that reach the framing behind the jamb, not just the trim, since that is where a forced entry usually fails.
- We check alignment: the bolt should throw fully and retract smoothly without you lifting, pushing or pulling the door. We run it with the door open and closed, with the key and from the inside, several times.
- We hand over the keys, show you how the lock works, explain any caveats about the door itself, and clean up the shavings.
How do salt air and damp wood doors change the job?
The data on Palos Verdes Estates is clear on one point: bluff-top coastal exposure brings salt spray and persistent fog, and exterior locks and hinges corrode fastest on homes near Bluff Cove and Lunada Bay. Marine damp also swells older wood doors for much of the year. Both matter when you install a deadbolt.
Swelling is the bigger alignment problem. A door that fits properly in one season can rub in another, and a bolt that lines up on a dry day can bind when the wood takes on moisture. We look at how the door actually fits before we drill, and where it binds we tell you whether the door needs planing or the hinges need attention, rather than forcing the bolt to make up the difference.
Corrosion affects what we recommend. Solid brass and stainless components generally hold up to salt better than thinly plated parts, and the finish you pick matters more near the bluffs than a few streets inland. Corroded hinges also let a door sag, which pulls the bolt out of line, so we check them while we are there.
Some upkeep helps. Wipe exterior hardware with a damp cloth now and then to remove salt film, and use a dry graphite-type lubricant in the keyway, not a heavy oil that collects grit.

Call (213) 577-1366What affects the cost of deadbolt installation?
We will not quote a figure on a web page, because the honest answer depends on your door. Here is what moves the cost, so you know what you are paying for when we explain it.
Replacing a deadbolt on a door that is already bored is usually the more economical route compared with boring new holes. If all you need is a different key, changing the cylinder or a lock rekey may be the lighter-cost option, and we will say so if that is what your situation calls for.
- New installation or replacement: new holes mean more labor and more chance of door repair.
- Door material: solid wood, steel, fiberglass and glazed doors each need different tools and care.
- Lock grade and brand: a basic residential bolt and a heavier-duty one are different products with different internal parts.
- Single or double cylinder, and whether the cylinders are keyed alike with your other locks.
- Finish: coastal-rated or specialty finishes cost differently from standard ones.
- Door or frame condition: a split jamb, worn bolt hole or sagging hinge adds repair work.
- Number of doors, and the time of day or distance of the visit.
Deadbolts in Malaga Cove, Valmonte, Lunada Bay and Montemalaga
Palos Verdes Estates was master-planned in the 1920s with involvement from the Olmsted Brothers, and Spanish Colonial Revival and Mediterranean styles still dominate. Housing is almost entirely single-family. That shapes deadbolt work more than people expect.
In Malaga Cove and Valmonte, many homes date from the 1920s to the 1940s, and many retain vintage mortise locks and original hardware that call for specialty service rather than simple replacement. On those doors, adding a deadbolt often means working around an existing mortise lock in aged wood, so we judge first whether the old hardware should be serviced and kept, and where a separate deadbolt can go without weakening the door. In Montemalaga and Lunada Bay, where mid-century ranch and view homes are common, doors are more often standard prepared doors, though the bluff exposure near Lunada Bay brings the salt and damp issues covered above.
Exterior changes in the city are reviewed by the Palos Verdes Homes Association art jury. We cannot speak for the association, but if a new deadbolt will change the finish or trim visible from the street, check with them before you order. We can match the finish of existing hardware so the front door looks the same afterward.
One scenario comes up often in 90274: rekeying after estate sales and property transfers. New owners often find an old, loose or mismatched deadbolt and decide to replace it while the keys are being sorted out. If you are standing outside a locked door in Lunada Bay or Valmonte right now, that is a different call; see house lockout help. Our Westwood storefront is about 24 miles away, so we plan each trip rather than pretend we are around the corner.

Call (213) 577-1366Install, replace, rekey or upgrade: which do you need?
People often call for a deadbolt when a different service fits better. This page covers installing and replacing deadbolts; here is how the neighboring services differ.
If the bolt works fine but you do not know who holds keys, a rekey may be enough. If the whole lockset is worn, corroded or damaged, lock replacement may make more sense than patching one part. If you want a bolt that resists picking, drilling and bumping better than a standard residential one, ask about high-security locks. And if you want keypad or app control, that is a separate smart lock installation conversation, with its own battery, door-fit and power questions.
- Door has no deadbolt, or the bolt is failing: deadbolt installation or replacement, covered here.
- Bolt is fine but keys are unaccounted for: rekey.
- Whole lockset is damaged or corroded: lock replacement.
- Want better pick and drill resistance: high-security locks.
- Want keypad or app control: smart lock installation.

How do you check a locksmith before they drill into your door?
California requires locksmith companies to hold a license through the Bureau of Security and Investigative Services (BSIS), called an LCO license. Ask any locksmith for the license number, including us, and check it with the state before they start work. A company that dodges the question is telling you something.
Also ask for the company name, not just a first name, and ask them to explain the cost drivers for your door before work begins. A deadbolt is a small job, but it is also the lock between your family and the street, and it is worth a few direct questions.
Frequently asked questions
How long does deadbolt installation take?
A replacement on a door that is already bored is a short visit. A new installation takes longer because we bore the door, cut the strike pocket and check alignment. A swollen or damaged door adds time. When you call (213) 577-1366, we will tell you what to expect for your door.
Can you add a deadbolt to a door that does not have one?
Usually yes. The door needs to be thick and solid enough to take the bore holes and hold the bolt. Very thin, hollow or damaged doors may need reinforcement first, and we will tell you that honestly before drilling.
Do I need a double cylinder deadbolt on a glass door?
Not always. It helps when glass is within reach of the thumb turn, but it means you need a key to leave in an emergency. Some rules restrict it on certain doors. We will go through the trade-off and the alternatives before installing one.
I have an original mortise lock on a 1920s home. Can you still add a deadbolt?
Often, yes. Older Spanish Revival homes in Malaga Cove and Valmonte frequently have vintage hardware worth keeping, so we check the door and the mortise lock first and decide where a deadbolt can sit without weakening the wood.
Will salt air damage a new deadbolt near the bluffs?
It can corrode lesser parts over time, especially near Bluff Cove and Lunada Bay. We lean toward solid brass or stainless components and a finish suited to coastal exposure. Wiping the hardware occasionally and using a dry graphite-type lubricant helps.
Do I need Homes Association approval to change my deadbolt?
We cannot speak for the association. Exterior changes in Palos Verdes Estates are reviewed by the Palos Verdes Homes Association art jury, so if the new lock changes what shows from the street, check with them first. We can match your existing finish.
Can all my deadbolts be keyed alike?
Yes. We can key new deadbolts to match each other or your existing locks so one key works across your doors. Tell us which doors you want included when you call.
I just bought a house in Palos Verdes Estates. Should I replace the deadbolts or rekey them?
If the deadbolts are solid and working, rekeying is often the more economical route because it makes old keys useless. If they are loose, corroded or hard to turn, replacement is worth it. We can inspect each door and tell you which.
Do you install deadbolts at night or on weekends?
Our phone line is answered 24 hours a day, 7 days a week, year-round, and our mobile vans serve Palos Verdes Estates. Call (213) 577-1366 and we will go over the door and the timing together.
