What does deadbolt installation in Redondo Beach involve?
A deadbolt is the lock that does the real work on an exterior door. The knob or lever latch on most doors is a spring bolt. It keeps the door shut against a breeze, but it isn't built to resist a shoulder or a pry bar. A deadbolt throws a solid bolt into the door frame, and that bolt does not retract until the cylinder or thumb turn is operated. Deadbolt installation means fitting that lock to your particular door properly: the right bore, the right backset, a strike plate that lines up with the bolt, and screws long enough to reach the framing behind the jamb rather than just the trim.
Most deadbolt calls in Redondo Beach fall into a few groups. Some doors have no deadbolt at all, only a knob latch. Some have a deadbolt that has worn out, been damaged in a break-in attempt, or seized up from years of coastal air. Others are move-ins, where a new owner or tenant wants a lock they know the history of. Each of these is a slightly different job, and we treat them that way instead of running one routine on every door.
If you are not sure which group you are in, describe the door to us on the phone: wood, metal, or fiberglass; whether there is already a hole drilled above the knob; whether the door sticks in damp weather. That is usually enough for us to bring the right hardware on the first trip.
Should you add a new deadbolt or replace the one you have?
Deadbolt replacement is the better route when a deadbolt already exists but has stopped doing its job. Signs include a key that turns hard or only works with a jiggle, a bolt that does not fully extend, a cylinder that spins freely, a thumb turn that has gone loose, or visible rust and pitting on the face. Swapping a deadbolt into an existing bore is generally quicker than cutting a new one, because the door has already been prepared. We still check the strike and the bolt alignment, since a worn lock is often a symptom of a door that has shifted.
- Add a new deadbolt when the door only has a knob or lever latch and no separate bolt.
- Replace the deadbolt when the existing one is worn, corroded, broken, or no longer operates smoothly.
- Replace it also when you want a stronger grade of lock than what the builder installed.
- Consider only rekeying if the lock works well and your concern is who holds keys. That is a different service, covered on our lock rekey page.

Call (213) 577-1366How do we install a deadbolt, step by step?
The process below is how a typical installation on a wood or solid-core door goes. Metal and fiberglass doors follow the same logic with different tooling, and we adjust as needed.
- Look at the door and frame. We check the door thickness, the condition of the edge, whether the frame is sound, and whether the door closes squarely before drilling anything.
- Confirm the hardware fit. We match the deadbolt to the door: backset, bore size, and bolt length. If a bore already exists, we verify that it is clean and sized correctly.
- Bore and mortise as needed. For a new deadbolt we cut the cross bore through the face and the bolt hole into the door edge using proper hole saws and a drilling guide, so the cuts are square and the wood is not split.
- Install the bolt and cylinder. The latch assembly goes into the edge, the cylinder passes through the door, and the interior thumb turn or second cylinder is secured on the inside.
- Set the strike. We mark and chisel the strike plate so the bolt lands in the center of the hole. We fasten it with long screws that bite into the stud, which matters more for break-in resistance than most people expect.
- Test with the door open and closed. The bolt should throw and retract with no binding and no need to lift or push the door. If it drags, we correct the alignment instead of leaving a stiff lock behind.
- Hand over the keys and show you how it works. We cut or provide the keys, explain any quirks of the lock, and discuss whether other doors on the property should match.
Single or double cylinder: which deadbolt is right for your door?
A single-cylinder deadbolt uses a key on the outside and a thumb turn on the inside. It is by far the most common choice for homes, and it is what we recommend for most doors because you can leave quickly without hunting for a key.
A double cylinder deadbolt installation puts a keyed cylinder on both sides. The reason people ask for it is usually a door with glass in it or beside it. Someone who breaks the glass cannot reach through and turn a thumb turn. That is a real benefit, and it comes with a real trade-off: in a fire or emergency, anyone inside needs a key to get out. Because of that, building and fire codes restrict keyed-both-sides locks on many residential exit doors and in many rental and multi-family settings. Rules vary by property type and by the local building department, so we will not just assume it is allowed on your door.
If you want a double cylinder, we will talk through where it is appropriate, how you would keep a key within reach of the door, and what alternatives exist. One alternative is a single-cylinder deadbolt paired with a security film or a reinforced pane. Another is a thumb turn that is positioned beyond arm's reach from a broken pane. We will give you our honest view, and it is your decision.
- Single cylinder: key outside, thumb turn inside. Faster exit, fits most doors.
- Double cylinder: key both sides. Can make sense with nearby glass, but raises exit-safety and code questions.
- Tell us about the glass: how far it is from the lock, and whether the door is a primary exit for people in the home.
- For apartments and rentals, check with the owner or property manager before changing the type of lock.

Call (213) 577-1366What affects the cost of deadbolt installation?
We do not quote numbers on a web page, because the honest answer depends on the door in front of us. Here is what actually moves the cost up or down, so you can judge any quote you receive, ours included.
The first factor is the lock itself. Deadbolts are made in different grades, from basic builder-level units to heavier, pick- and drill-resistant ones. A higher-security cylinder, a reinforced strike, or a through-bolted design all cost more than a standard unit. If you are after something more robust, our page on high-security locks explains the options.
The second is the door and the work required. Adding a deadbolt to a door that has never had one involves boring and mortising, which takes more time than swapping a deadbolt into an existing hole. Hollow-core doors, damaged edges, steel doors, and out-of-square frames each add work. If a door has been drilled badly before, we may need to fit a repair insert first.
The third is the number of doors and whether the locks should be keyed alike. Several deadbolts on one key is convenient, and we can set that up, but it takes more planning than a single lock. Finally, the time of day matters. Calls at night, on weekends, or on holidays involve different logistics than a scheduled daytime visit. The most economical route is generally a scheduled visit with the hardware chosen in advance. We will give you the price for your specific job before work begins.
Deadbolt installation across Redondo Beach's neighborhoods
Redondo Beach covers a mix of building types, and the right deadbolt job depends on which one you live in. Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 20 miles away, and our mobile vans bring the hardware to your door.
In North Redondo (ZIP 90278), the two-on-a-lot townhome pattern means many front doors are tall, narrow, and shared across a small footprint. Golden Hills townhomes in particular have narrow entries where the front door is often the only street-facing barrier, so a solid deadbolt with a properly set strike makes a noticeable difference. Townhome lockouts are one of the situations we see here, and a worn or misaligned deadbolt is sometimes the reason the door stops working properly in the first place. If you are locked out right now, see our house lockout page first.
In South Redondo (ZIP 90277), you will find 1950s and 1960s single-family homes, beach homes in The Avenues, and condo buildings near the pier and the Esplanade. Older doors in these homes sometimes have a single worn latch and an add-on deadbolt installed years ago in the wrong place. In the Hollywood Riviera, hillside homes in Spanish and mid-century styles often have heavy wood doors and decorative hardware, so we match the finish and the look of the existing set as well as the function.
Brookside Village is a large gated condominium community. Condo rekeys and mailbox lock changes are common there, and a deadbolt swap often comes with the same visit. Before changing exterior hardware on a condo door, check your association's rules on finish and style. For the mailbox side of the job, we have a separate page on mailbox lock replacement.

Call (213) 577-1366How does salt air affect deadbolts near the coast?
Exterior hardware along the Esplanade, the pier, and King Harbor deals with steady salt-air corrosion. Inland parts of North Redondo are somewhat more sheltered, but the marine layer still keeps mornings damp for much of the year. That moisture works into cylinders, tailpieces, and strike plates. The result is a deadbolt that feels gritty, a key that sticks, or a bolt that no longer extends all the way.
When we install a deadbolt for a coastal-exposed door, we look at finish and material. Solid brass and stainless components generally hold up better than cheap plated hardware. A sealed or shielded cylinder helps, as does a door that has a covered entry or porch. We also point out simple maintenance: a dry graphite or PTFE-based lubricant in the keyway, not heavy oil that attracts grit, and an occasional check that the strike screws are still tight.
If your existing deadbolt is corroded, replacement is usually the practical fix. Cleaning can buy some time, but when the internal pins and springs are rusted, a fresh lock is a better investment than repeated repairs.
- Choose corrosion-resistant finishes for doors facing the water or exposed to wind.
- Keep the keyway lubricated with a dry lubricant rather than oil.
- Check strike screws once or twice a year, since swelling and drying of wood can loosen them.
- If the key feels rough, replace the lock before it fails closed.
Why call Wilshire Lock & Key for your deadbolt?
We have been in business since 1987. That is a long time to have been fitting locks to doors that are not square, frames that have settled, and wood that has swelled. It shows in the small details, like checking the frame before drilling and setting the strike by hand rather than trusting the template.
We are one company. We have a storefront at 10740 Wilshire Blvd and our own mobile vans, and the technician who comes to your door works for us. There is no dispatch middleman reselling your call to someone else. David, the owner and lead technician, oversees the work. Our phone is answered 24 hours a day, 7 days a week, every day of the year, at (213) 577-1366, so if a deadbolt fails at night, you can reach a real person.
Locksmith companies in California are required to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith you hire, us included, for that license information before work starts. It is a reasonable request, and a company that cannot answer it clearly is one to be cautious about.
Our mobile approach is covered in more detail on our mobile locksmith page.

Call (213) 577-1366What else should you consider alongside a new deadbolt?
A good deadbolt can only do as much as the door and frame allow. Before the visit, it helps to think about a few related items.
First, the door itself. A strong lock on a hollow or damaged door is only partly effective. We will tell you if the door edge or jamb needs reinforcement, and we can fit a reinforcement plate or a longer strike where that makes sense.
Second, keys and access. If you are replacing locks because of a lost key, a former roommate, or a tenant change, ask whether rekeying the existing hardware would meet the goal. If you are fitting several doors, we can key them alike. For general overviews of residential work, see our lock installation page.
Third, smart options. Some owners want a keypad or app-controlled deadbolt. We can discuss whether that fits your door and your routine on our smart lock installation page. For landlords managing several units, we also work with property owners through our locksmith for landlords service, which helps keep deadbolt specs consistent across doors.
If you would like to ask a question before booking, you can call us or use the form on our contact page.
Frequently asked questions
Can you install a deadbolt on a door that doesn't have one?
Yes. We bore the cross hole through the door face and the bolt hole into the edge, install the latch and cylinder, and set a strike plate in the frame. The door needs to be thick and solid enough to take the bore. If it is hollow or the edge is damaged, we will tell you what reinforcement is needed first.
How long does a deadbolt installation take?
A swap into an existing bore is generally quick. A new bore on a door that has never had a deadbolt takes longer, and a door that needs frame repair takes longer still. We will give you a realistic idea once we have seen the door, rather than promising a fixed time over the phone.
Is a double cylinder deadbolt legal and safe for my home?
It depends on the door and the property. Keyed-both-sides deadbolts can trap people inside during a fire if no key is at hand, so codes restrict them on many residential exit doors and in many rentals. We will discuss the rules that apply to your property and suggest alternatives if a double cylinder is not appropriate.
Can I replace a deadbolt myself, or should I call a locksmith?
Swapping a like-for-like deadbolt into a good bore is something many handy people do. The trouble tends to be a misaligned strike, short screws, or a wrong backset, which leave the lock working poorly or weak against force. If the door needs drilling, or the lock has jammed, a locksmith is the safer route.
Will a new deadbolt work with my existing keys?
Usually not by default, because a new deadbolt comes keyed to its own cylinder. We can key it to match your other locks if the brands and keyways allow it, so one key operates multiple doors. Tell us at the start which doors you want on the same key.
Why does my deadbolt stick near the coast?
Salt air and damp mornings corrode pins, springs, and bolts, and swelling wood can pull the door out of alignment with the strike. We check both. Sometimes a strike adjustment fixes it. If the cylinder is corroded inside, replacement is more dependable than cleaning.
Can you install a deadbolt in a condo or rental?
We can, but you should check first with your HOA or landlord. Condo associations often have rules on exterior hardware finish and sometimes on lock type, and rentals typically require owner approval. Once approved, we install to match what is allowed.
I'm locked out and my deadbolt is the problem. Can you help tonight?
Call (213) 577-1366. Our phone is answered around the clock, every day. We first get you inside, then look at whether the deadbolt should be repaired or replaced. You do not need to decide on a new lock until you are back in and can see what failed.
What grade of deadbolt should I choose?
For most homes, a good-quality residential deadbolt with a reinforced strike is a sound choice. If the door is at a street-facing entry, has a history of attempted break-ins, or sits in a corrosive coastal spot, a higher-security or corrosion-resistant unit is worth discussing. We will look at the door and suggest something that fits.
