Deadbolt Installation in Beverly Hills, CA

Why does a deadbolt matter more than the lock on your doorknob?

Most knobs and lever sets on front doors are there to keep the door closed, not to keep anyone out. The latch is a small, spring-loaded tongue, and on many doors it can be pushed back with a thin piece of plastic or forced with a shoulder. A deadbolt is a different kind of lock. It has no spring. The bolt is a solid steel cylinder that only moves when a key or a thumb-turn moves it, and once it is thrown into a properly reinforced frame, it takes real force to defeat.

That only holds true when the installation is right. The common failures are easy to list: a bolt fitted slightly off-center so it rubs the strike and never fully extends, a strike plate held by short screws into soft jamb wood, and a good deadbolt mounted in a door that is thin, split, or poorly bored. A deadbolt installed that way feels like security and delivers very little of it.

This page explains how we handle deadbolt installation and deadbolt replacement at Wilshire Lock & Key, how to choose between single and double-cylinder, and what to expect when a technician arrives at your door. If you only need a general overview of fitting new hardware, our lock installation service covers the wider picture.

Single or double cylinder: which deadbolt fits your Beverly Hills door?

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 entry doors, and it is what we recommend first, because anyone inside can get out immediately without finding a key. In a fire or any other emergency, that matters a great deal.

A double-cylinder deadbolt takes a key on both sides. The reason to choose one is almost always glass. If your door has a window, a sidelight, or a decorative glass panel within arm's reach of the thumb-turn, someone can break the glass, reach through, and turn the bolt. Double cylinder deadbolt installation removes that weakness, but it trades it for another: if you cannot find the key quickly, neither can anyone trying to leave the house in a hurry.

So we talk it through before we install anything. Building and fire rules on keyed-both-sides locks for residential doors vary, and some buildings restrict them, so if you live in a condo or apartment, check with your building manager or HOA first. If a double-cylinder is a poor fit, there are other routes: a single-cylinder with the nearby glass reinforced or replaced, a thumb-turn placed out of reach, or a different door entirely. We will tell you plainly which one makes sense for your door.

Here is what we weigh when we help you pick hardware:

• Door material and thickness: solid wood, steel, fiberglass, or hollow-core each take a deadbolt differently.
• How close glass sits to the inside thumb-turn.
• Hardware grade: ANSI/BHMA Grade 1 is the most robust, Grade 2 suits most homes well, and Grade 3 is the lightest duty.
• Whether you want the key to match your existing locks or a fresh keyway.
• Finish: the deadbolt should look like it belongs with the rest of your hardware.
• Whether you are curious about a keypad or app-based bolt, which we handle under smart lock installation.

How does Wilshire Lock & Key install a deadbolt, step by step?

Every door is a little different, but the sequence below is how a standard deadbolt installation goes. The work that you cannot see afterward, the boring, the alignment, and the strike, is the part that decides whether the lock performs.

1. You call (213) 577-1366 and describe the door: material, whether there is already a deadbolt hole, whether there is glass nearby, and whether this is a new install or a replacement.
2. The technician inspects the door and the frame on arrival. We check the door's thickness, the condition of its edge, the strength of the jamb, and any existing holes.
3. We settle on the hardware together: single or double-cylinder, grade, finish, and backset, which is the distance from the door edge to the center of the bolt, usually 2-3/8 or 2-3/4 inches.
4. If the door has no deadbolt hole, we mark the height and use a drilling jig to cut the cross bore (typically 2-1/8 inches) and the edge bore (typically 1 inch) square to each other. If we are replacing a bolt, we confirm that the existing holes match the new hardware.
5. We fit the bolt assembly into the edge, then mount the exterior cylinder and interior thumb-turn or second cylinder and tighten the through-bolts evenly.
6. We cut the strike mortise flush, set the strike, and drive long screws that reach the framing behind the jamb, not just the trim wood.
7. With the door closed, we throw the bolt fully and repeatedly, check that nothing rubs, and test every key from both sides where applicable. If the bolt drags, we fix the alignment rather than leave it for you to learn to live with.
8. We hand over the keys, show you how the lock works, and tell you anything about the door that is worth watching, such as a warped edge or a worn hinge.

When is deadbolt replacement the better call than a new installation?

Plenty of calls we get are not new installs. The door already has a deadbolt, and the question is whether to keep it. Deadbolt replacement is usually the better path when the old bolt is worn and sticks, when the cylinder is damaged, when the finish has failed, or when you want a higher grade of hardware than the builder installed. A replacement that fits the existing holes is typically a lighter job than drilling a new door, because the hard preparation is already done.

If your bolt works fine but you are worried about who holds keys, replacement may not be necessary. Changing the internal pins so old keys stop working is a separate service called lock rekeying, and it is often the more economical route. We will say so on the phone if we think rekeying solves your problem, rather than selling you a new lock you do not need.

And if the old deadbolt is a basic builder-grade piece protecting a door you care about, an upgrade is worth discussing. Our page on high-security locks explains the options for keyways that resist picking and unauthorized duplication.

What affects the cost of deadbolt installation in Beverly Hills?

We do not quote a flat number sight unseen, because the same phrase, deadbolt installation, covers jobs of very different sizes. Here is what actually moves the cost:

• New holes or existing holes. Drilling a door that has never had a deadbolt is more work than swapping hardware into a bore that is already there.
• Door material. Solid wood, steel, and fiberglass all need different bits and care, and an older or decorative door takes more patience.
• Hardware grade and brand. A heavier-duty bolt with a reinforced strike costs more than a basic one, and it lasts and resists force differently.
• Single or double cylinder. Double-cylinder hardware is a different product, and the extra thinking about safety and codes is part of the job.
• Frame reinforcement. A strike box, a longer strike, or a door-edge plate adds material and labor but meaningfully improves how the door resists force.
• Number of doors and keying. Several doors keyed to one key are more involved than a single bolt.
• Timing. A middle-of-the-night visit is not priced like a scheduled daytime appointment.
• Distance. Beverly Hills is near our Wilshire Boulevard storefront in Westwood, so travel is a modest factor here.

What does deadbolt installation look like across Beverly Hills?

Beverly Hills is not one kind of housing, and deadbolts get chosen differently depending on where you live. Whether your address falls under 90210, 90211, or 90212, the door and the building will shape the job.

In the estate-heavy areas, many homes date from the 1920s onward and run to Spanish Colonial Revival, Mediterranean, and traditional styles. The doors tend to be heavy and decorative, and the right approach is careful drilling and hardware whose finish suits the door. Estate properties also commonly pair high-security deadbolts with driveway gates, intercoms, and monitored access. In Trousdale Estates, a mid-century enclave from the 1950s and 1960s, the front door deadbolt is one piece of a wider system, and gate-side hardware is its own matter, which we cover under gate lock repair.

In The Flats, a scenario we hear about is a household changing staff or vendors, and an owner wanting the front-door locks brought up to a higher level of security. Sometimes that means rekeying, but when the existing deadbolt is a basic one, installing a better-grade bolt with a reinforced strike can be the smarter move, because it deals with the key problem and the hardware problem together.

South of Wilshire, the city shifts to duplexes, condominiums, and apartment buildings from the 1930s through the 1970s. Doors there are often thinner or older, and a building may have rules about hardware, keying, or double-cylinder locks, so confirm with your manager or HOA before we begin. If you are ever locked out of one of these units while sorting this out, see our apartment lockout page.

In the Golden Triangle and along Rodeo Drive, the work is commercial rather than residential, and boutique and office doors have their own requirements. For those, start with storefront lock repair.

As for weather, Beverly Hills sits inland of the strongest marine influence, with warm, dry summers. Hillside and canyon sections get strong sun that fades and dries exterior door finishes. The effect on hardware is modest, but a dried-out door can shift slightly, so we check alignment with that in mind and suggest finishes that hold up to sun. Our Westwood storefront is about four miles from Beverly Hills, and our mobile vans bring the tools and a range of deadbolts to you.

Why call Wilshire Lock & Key for your deadbolt?

We have been in business since 1987. That is long enough to have installed deadbolts in nearly every kind of door and frame, and to know which shortcuts come back as callbacks. David, the owner and lead technician, oversees the work.

We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, and we are one company. When you call (213) 577-1366, you reach us, not a dispatch center that hands the job to whichever subcontractor is free. The person who answers the phone works for the company that sends the technician, and that makes it easier to answer questions about your specific door.

We answer the phone 24 hours a day, 7 days a week, all year, which matters when a break-in, a failed lock, or a move-out leaves you needing a door secured tonight. Our residential locksmith services include deadbolts as part of a broader approach to home security, so if you also need keys, rekeying, or repairs, it can all be handled together.

What should you ask before hiring anyone to install a deadbolt?

Ask about the license. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license, and you should ask any locksmith you are considering for their license number. It is a fair question and a reasonable one to check.

Ask what the job will involve. A straight answer should cover whether new holes are needed, what grade of hardware is going in, and what is included in the total. Be cautious of anyone who quotes a surprisingly small number over the phone and then changes the story at the door.

Ask what happens if the bolt does not fit your door cleanly. A good technician will adjust the alignment, reinforce the strike, or advise a different approach, not just hand you a lock that sort of works. That is how we approach every installation.
