What does lock installation include in Westmont?

Lock installation means fitting a lock that is not on the door yet, or fitting a different kind of lock than the door was originally set up for, and making sure it works as part of the door. That sounds simple, but most of the work is not the lock itself. It is the door: the bore holes, the latch edge, the strike plate, the frame behind it, and whether the door closes squarely enough for a bolt to throw all the way.

We handle door lock installation on front doors, back doors, security screen doors, interior doors that need a privacy or keyed lock, and storefront and office doors. We fit knobsets, lever handles, deadbolts, mortise locks and higher-security hardware, and we set up the keys so you know exactly who holds a copy.

This page is about the fitting itself. A lock that is correctly chosen but poorly installed will bind, rattle, or fail to bolt, and a good lock on a badly aligned door gives you very little. So we treat the door as half the job.

Do you need a new installation, or something simpler?

Before we cut or drill anything, we work out whether installation is really the right job. Sometimes it is not, and the simpler route saves you time and materials. Here is how we sort it out:

We will tell you which category your door falls into on the phone and confirm it when we see the door. If the honest answer is that you do not need an installation, we will say so.

  • If the lock works but too many people may hold keys, a lock rekey changes the inside of the cylinder and leaves the hardware where it is.
  • If a lock is worn, damaged or failing, a like-for-like lock replacement on the existing holes is often the more economical route.
  • If the door has no deadbolt, or the hardware does not suit how the door is used, that is a true new installation.
  • If you want a second lock, a different style of handle, or a lock on a door that never had one, that is also new installation, and it may involve drilling and chiseling.

How does lock installation work, step by step?

Every door is a little different, but the process is consistent. This is how a typical visit goes:

  1. You call (213) 577-1366, any hour. We ask what kind of door it is, what is on it now, what you want on it, and whether it is wood, metal, glass or a security screen door.
  2. A mobile technician comes to you in one of our vans. If you would rather look at hardware first, call ahead and arrange a visit to our storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024.
  3. The technician inspects the door: its thickness, the condition of the edge, any existing holes, the frame, the strike side, and whether the door hangs true.
  4. We explain the hardware options and what will drive the cost on your particular door, and we agree on the work before anything is drilled.
  5. We prepare the door. That means marking the positions, boring the holes to the right size and backset, and cutting the latch mortise or the mortise pocket if the lock calls for it.
  6. We fit the lock body, cylinder and handle, then install the strike plate and, where the frame allows, long screws that reach the framing behind the jamb rather than only the thin trim.
  7. We test it properly: door open and closed, bolt thrown and retracted, keys from both sides, repeated many times, and with the door pulled and pushed the way a real person uses it.
  8. We hand over the keys, show you how the lock operates, and clean up the shavings and packaging.

Which locks can we install: deadbolts, mortise, lever and security locks?

Most calls fall into a few families of hardware. Each one has its own quirks when it goes onto a door.

  • Front door lock installation: a front door usually gets a deadbolt plus a knob, lever or handle set. If a deadbolt is the main thing you want, our deadbolt installation page goes deeper on grades, bolt length and strike reinforcement.
  • Mortise lock installation: a mortise lock sits in a deep pocket cut into the edge of the door, with the lock body inside the door itself. It is more involved than a standard bored lock, because the pocket has to be the right size and depth, and the door edge has to be solid enough to hold it. If your door already has a mortise pocket, the replacement body has to match it.
  • Lever lock installation: lever handles are easier to work with full hands, a heavy bag or limited grip, and they come in different functions: passage (no lock), privacy, entry and storeroom. Picking the right function matters as much as the finish.
  • Security lock installation: this means higher-grade cylinders, reinforced strike plates, longer screws and sometimes a door or frame reinforcer. Our high-security locks page covers the cylinder side of that.
  • Electronic and keypad locks: we fit these too, with the same attention to door prep. The smart lock installation page covers what to consider before choosing one.

Residential and commercial lock installation: what changes?

Residential lock installation is usually about a front door, a back door and perhaps a side entry. The goals are straightforward: the door should lock firmly, the key should turn smoothly, and the hardware should look right on the house. We usually work around your schedule, and most of the care goes into not marring the door finish.

Commercial lock installation has different demands. A storefront or office door is opened and closed many times a day, so the hardware needs to be built for that cycle. The door may be aluminum and glass with a narrow stile, which limits what will fit. Lever handles and mortise locks are common on commercial doors, and the lock function has to match how the business operates, for example whether the door must be able to stay unlocked during business hours. Closers, exit devices and key control may all come into play. For wider commercial work, see our commercial locksmith services.

We will ask a few direct questions when we plan a commercial installation: how many people need access, whether the door is part of an exit route, and who will manage the keys. Those answers shape the hardware more than the brand name does.

What affects the cost of lock installation in Westmont?

We will not quote a number on a web page, because the price depends on the door and the hardware, and we would rather give you an honest figure after we have heard the details. These are the things that actually move the cost:

  • The type of lock: a mortise lock takes more preparation and more precise fitting than a standard bored deadbolt or knobset.
  • The grade of the hardware: heavier-duty locks and reinforced plates cost more than basic residential sets.
  • The door itself: solid wood, hollow-core, steel, aluminum storefront and security screen doors each need different tools and techniques.
  • What is already there: a door with matching holes is quicker than one that has to be drilled from scratch, and a door with damaged or split edges may need repair first.
  • The frame: if the jamb is cracked or the door has dropped out of alignment, fixing that is part of making the lock work.
  • How many locks and keys: several doors, keyed-alike sets or extra keys add time and parts.
  • Who supplies the hardware: you can buy the lock yourself, or we can supply it. If you supply it, we will check that it fits your door before we start.
  • When you call: after-hours and emergency visits are a different job from a planned daytime appointment, and distance matters too. Westmont is roughly 14 miles from our Westwood base.

Why call Wilshire Lock & Key for installation?

We have been in business since 1987. In that time we have fitted a great many locks on a great many badly aligned doors, and that experience shows up in the small details nobody sees afterward: the right screw length, the clean chisel work, the strike plate set flush.

We run a real storefront at 10740 Wilshire Blvd in Westwood and send mobile service vans out across 140 cities in Los Angeles and Ventura counties, Westmont included. When you call, you reach our company, not a call center that passes the job to whichever subcontractor picks it up. There are no dispatch middlemen. David, the owner and lead technician, oversees the work.

Someone answers (213) 577-1366 around the clock, every day of the year. If you are locked out of the job first and need installation second, our mobile locksmith service is how we reach you.

One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license. You should ask any locksmith for that license number, us included, and check it with the state before you hand over a door. A locksmith who will not tell you is a locksmith to skip.

What does lock installation look like around Westmont?

Westmont is an unincorporated area of Los Angeles County, with ZIP codes 90044 and 90047. It is densely built. The older housing includes 1920s to 1940s bungalows and Spanish-style cottages, with small postwar homes and two-story apartment buildings mixed in, particularly along Vermont, Normandie and Western avenues. Renters make up a large share of households, and security screen doors and window bars are widespread.

That mix shapes the installation work. One common job here is a deadbolt or security-door hardware upgrade on an older bungalow. The old door may have only a basic knob lock, or a deadbolt that does not line up any more. Adding a proper deadbolt means checking that the door is thick and sound enough to take it, and then reinforcing the strike side. On a house with a security screen door in front of the main door, the screen door latch and the main door lock both need to be considered, because the lock on the screen is only as strong as the frame it sits in.

The climate adds one thing to watch. Westmont sits on a flat inland coastal plain with a regular morning marine layer and mild temperatures. Corrosion is minor, so standard finishes hold up fine. Damp winter mornings, though, can swell older wood doors and frames, so we leave proper clearance at the latch edge and check that the lock still operates on a damp day and not just a dry afternoon.

Along the Vermont Avenue, Western Avenue and Normandie Avenue corridors, apartment doors and shared entries often call for quick, careful work. We also see requests around Vermont Avenue and Manchester Avenue and across the Manchester Avenue and Century Boulevard corridors, where storefront doors need commercial hardware that holds up to heavy daily use. Customers in the Jesse Owens Park area, and those close to Vermont Knolls or Morningside Park in Inglewood, can call us the same way.

Small multifamily buildings in Westmont bring a different request: new locks for a turnover. If you manage rentals, the locksmith for landlords page explains how we handle several doors and key control across a property. A mailbox lock along Vermont or Western is a related small job, and we can mention it when we are on site.

How should you prepare for a lock installation visit?

A little preparation makes the visit shorter and the result better.

  • Know which door or doors need work, and whether anything is already on them.
  • If you bought the lock, keep the box and all of the parts, including the template and the strike plates.
  • Clear a path to the door and make sure someone authorized can be present.
  • If you rent, check your lease or ask the landlord before changing hardware, since a landlord may need to keep a key.
  • Tell us about anything unusual: a door that sticks in winter, a screen door with a bent frame, or earlier repairs around the latch.

Frequently asked questions

How long does a lock installation take?

It depends on the door. A standard deadbolt on a door that is sound and already drilled is a short visit. A mortise lock, a door with a damaged edge, or several doors on a property takes longer. When you call (213) 577-1366 we ask the right questions so we can give you a realistic idea before we arrive.

Can you install a lock on a door that has no holes for it?

Yes. We bore the holes at the correct size and backset, cut the latch edge, and fit the strike plate in the frame. We check the door's thickness and condition first, since a very thin or weak door may need reinforcement to hold the lock properly.

Can you install a lock on a security screen door?

Usually, yes. The outcome depends on the frame. Thin metal frames limit which locks will fit, and a bent or loose screen door has to be dealt with first. We will look at it and tell you what the frame can hold. Security screen doors are common in Westmont, so we see them often.

What is the difference between a mortise lock and a regular deadbolt?

A regular deadbolt is installed in round holes drilled through the face and edge of the door. A mortise lock sits in a deep rectangular pocket cut into the door edge, with the lock body inside the door. Mortise locks take more careful fitting and a solid door edge. If your door already has a mortise pocket, the replacement has to match it.

Do I have to buy the lock myself, or can you supply it?

Either way works. We can supply hardware that suits your door and your use, or you can buy your own. If you bring your own, tell us what it is when you call, and we will check that it fits your door and is a suitable grade for the job before we start work.

Can new locks be keyed to match my existing keys?

Often, yes, depending on the brand and keyway of the locks involved. If you want several doors on one key, tell us up front so we can choose compatible hardware. We confirm what is possible once we see what you have.

I rent my home. Can I have a lock installed?

That is between you and your landlord or lease. Many leases require permission, and a landlord may need a key. If you are a landlord or manage units, we can fit and key several doors together, so you hold control of the keys.

Do you do lock installation at night or on weekends?

Yes. Our phone line, (213) 577-1366, is answered 24 hours a day, 7 days a week, all year. After-hours work is priced differently than a planned daytime job, so tell us if the work can wait for regular hours.

Are you licensed?

California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for the license number, us included, and verify it with the state before work begins. It is a fair question and a reasonable thing to check.
