Drilling a clean bore for a new lockset in a wooden door

What does lock installation in Monterey Park actually involve?

Putting a new lock on a door sounds simple until the door says otherwise. The hardware has to match the door's thickness, the size and position of the bore holes, the edge preparation, the strike plate, and the frame behind it. A lock that is the right brand but sits slightly off will drag, stick, or never throw the bolt all the way into the jamb. Most of the work in a good installation is measuring, fitting and checking, not just turning screws.

People call us for a handful of reasons: a remodel or new construction where the doors have no hardware yet, an old knob set that needs to become something sturdier, a side or garage door that never had a real lock, a move-in where the owner wants a particular setup, or a business fitting out a new space. In each case the question is the same: what is the right lock for this specific door, and how do we mount it so it works smoothly for years?

It helps to know where installation ends and its neighbors begin. If your locks work but you want different keys, that is lock rekeying. If an existing lock is worn out or broken and needs to come off and be swapped for a new unit, that is closer to lock replacement. This page is about fitting new hardware to a door, including doors that have never had it, and doing that cleanly.

Which types of locks can we install?

We install the full range of residential and commercial hardware. Here is how the common requests break down, using the terms people usually search for.

  • Front door lock installation: entry handle sets, deadbolt-and-handle combinations, and keyed knob or lever sets for the main entrance, fitted so the latch and bolt line up with the strike without forcing the door.
  • Door lock installation for other doors: back doors, side gates into the house, garage service doors, bedroom and office doors that need a keyed or privacy function.
  • Lever lock installation: lever handles in place of round knobs, popular for easier grip and common in commercial and accessibility-minded settings.
  • Mortise lock installation: the heavier lock body that sits inside a pocket cut into the edge of the door, found on older homes, many storefronts and a lot of commercial doors.
  • Security lock installation: higher-grade cylinders, reinforced strike plates and longer screws for doors that need to resist force. See our page on high-security locks for the cylinder options.
  • Deadbolts: single-cylinder and double-cylinder bolts added to an existing door. We cover those in detail on the deadbolt installation page, and electronic options on the smart lock installation page.
  • Commercial lock installation: grade-appropriate cylinders and lock bodies for offices, restaurants and shops, plus the door hardware that goes with them. Our commercial locksmith page covers the wider business side.

How does a lock installation go, step by step?

Every door is a little different, but the sequence we follow is consistent. Nothing here is rushed, because the order matters: the lock only works as well as the preparation behind it.

  1. You call (213) 577-1366 and tell us which door, what is on it now (if anything), and what you want it to do. We ask about the door material, whether it is a house, condo or business, and whether you already have the lock or want us to supply it.
  2. We recommend hardware that suits the door and your situation. If a lighter, simpler lock will do the job, we say so. If the door or frame is the weak point, we tell you that too, rather than selling a strong lock on a weak door.
  3. We come to you in a mobile van. Common hardware is carried on board. If your door needs something unusual, we may need to source it, and we tell you that before work begins.
  4. We inspect the door: thickness, bore holes, edge bore, condition of the wood or metal, the strike plate and the jamb. Any prep that is needed, such as enlarging a bore, cutting a mortise pocket or reinforcing a frame, is explained before we cut.
  5. We install the lock body, latch, bolt and trim, and fit a correctly positioned strike plate with screws long enough to reach the framing, not just the thin jamb.
  6. We test the lock with the door open and closed, check that the bolt extends fully, that the latch catches without slamming, and that every key turns smoothly. We adjust until it operates with ordinary hand pressure.
  7. You get all the keys, a quick walkthrough of how the lock works, and honest advice on anything else about the door that will affect how long the hardware lasts.

When does a mortise or lever lock make sense?

Mortise lock installation is its own craft. The lock body is a rectangular box that slides into a deep pocket cut in the edge of the door, and the knob or lever and the keyed cylinder connect to it. If the door already has a mortise pocket, the job is matching the new body to the old pocket, and mortise bodies come in several sizes, so we measure before ordering. If the door has never been prepared for one, we have to cut the pocket accurately, which is not a job for a rushed hand on a door you want to keep. Mortise locks are popular for their sturdiness and long service life, and on older doors they are often the original hardware worth keeping or matching.

Lever lock installation is mostly about how the lock is used. A lever is easier to operate with a full hand, a wrist, or an elbow, which matters for people with arthritis, for anyone carrying groceries, and for many commercial doors. Levers can sit on a standard cylindrical lock or on a mortise body, so the choice of lever style and the choice of lock body are separate decisions. If a business needs to meet accessibility requirements, the building owner or a code professional should confirm what applies. We can fit the hardware you choose and tell you what we see on the door, but we do not make code determinations for you.

What affects the cost of lock installation in Monterey Park?

We do not publish numbers on a web page, because the same phrase, new lock, can mean a very small job or a half-day project. What we can do is tell you what moves the cost, so the figure you hear on the phone makes sense. When you call, we describe the job and what is likely to change it before we come out.

  • The lock itself: a basic keyed knob set, a grade-rated deadbolt, a mortise body and a high-security cylinder are very different products at very different cost levels.
  • The door: solid wood, hollow-core, metal, fiberglass and glass storefront doors all need different handling. A door that was never bored for a lock needs more work than one with ready-made holes.
  • Preparation work: cutting a mortise pocket, enlarging or re-boring holes, repairing a split edge, or reinforcing a frame adds time and sometimes parts.
  • How many locks: several doors on one visit, or a set of locks keyed alike, usually costs less per door than separate trips.
  • Supplied hardware: if you have already bought the lock, we can often install it. We will tell you if it is a poor fit for the door, because installing the wrong lock well is still the wrong lock.
  • Special-order parts: when we need to bring in hardware we do not carry, that can add a second visit and extra cost.
  • Timing and location: night, weekend and holiday calls can cost more than a scheduled daytime visit, and the travel to your address plays a part. Booking the work ahead of time is usually the more economical route, but we are here around the clock when you cannot wait.

Lock installation across Monterey Park: hillsides, flats, Atlantic and Garvey

Monterey Park's housing is mixed, and that shapes what we bring to a job. In the southern flats near Montebello, prewar bungalows often still carry original doors and older hardware. Those wood doors can be worth saving, so installation there tends to be careful work: matching existing bores where we can, and checking for old paint, swollen edges or a worn frame before drilling anything new. If you are in that part of town and your front door lock installation is overdue, we look at the door first and the lock second.

On the hillside streets of the Monterey Highlands area in the northeast hills, and in the northern hillsides near Alhambra, you often see postwar ranch homes with long driveways and detached garages. Those layouts create doors that get less attention: a side door off the garage, a back entry well away from the street, a gate into the yard. We often find those are the doors with the weakest hardware, and fitting a proper lock there can matter as much as the front door. Sun-exposed hillside doors weather faster than ones in the flats. The effect on locks is modest, but we pay attention to finishes and to how the door has moved over the years, since a door that has shifted needs the strike plate repositioned, not forced.

Along Atlantic Boulevard and Garvey Avenue, there is a lot of 1980s to 2000s condo and townhome construction, along with shops and restaurants. Condo and townhome owners near Atlantic Times Square often have two questions: what are we allowed to install, and what is shared? Shared-entry and mailbox hardware generally belongs to the building or association, so check the rules before changing an exterior door. Your unit's own entry door lock is usually yours to choose, subject to any community requirements. If you are locked out of a condo instead, that is a different call, and we handle it on our emergency locksmith service.

Restaurants and storefronts along Garvey and Atlantic have their own needs. A new tenant may need a lock fitted to a glass or aluminum storefront door, a back-of-house door that locks securely, or an office door with a lever set. Commercial lock installation there is typically about durability and ease of daily use, with staff opening and closing the same door many times a day. We can talk through the options on the phone, then confirm on site.

Whether your address falls in ZIP code 91754 or 91755, we serve it from our Westwood storefront and mobile vans. Monterey Park is about 19 miles from our base, so we plan the trip around the hardware you need. If the job needs something we do not carry, we say so up front instead of making you wait on the porch while we find out.

Residential or commercial: how the job changes

Residential lock installation usually centers on the people living there: who needs keys, whether children or older family members have to operate the lock easily, and how the door sits in daily weather. A front door gets used constantly and needs smooth operation; a back door might call for something heavier because it is less visible. We install what the household needs, including matching keys across several doors so you carry one key instead of four.

Commercial lock installation is more about duty cycle and control. A shop door might be opened dozens of times a day, so we choose hardware built for that. A business may also want a master key arrangement, keyed-alike doors, or a way to remove a former employee's access without replacing everything. If you manage a rental property, the same thinking applies to multiple units and turnover between tenants. When the job moves into storefronts, panic hardware or access control, the right page is our commercial locksmith service, and we can help you work out what the door actually requires.

How do you choose a locksmith for a new lock?

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO (Locksmith Company Operator) license. Ask any locksmith for it, whoever they are, before they start work, and check that the name on the license matches the company that arrives. That one question screens out a lot of trouble.

A few other things are worth asking. Will the person who answers the phone be the person who sends the technician, or is it a call center that passes the job to whoever is available? Can they tell you in plain terms what lock they plan to put on the door and why? Will they explain extra charges before beginning? A good installer is comfortable with all three. We are happy to answer them whenever you call.

Why call Wilshire Lock & Key for installation?

We have been in business since 1987, and the same shop has been fitting locks to doors in Los Angeles and Ventura counties for all of those years. We serve 140 cities, and Monterey Park is one of them. That experience shows up in the small judgments: knowing when a door needs a shim behind the strike, when an old mortise should be kept, and when a lock has to go on a different door entirely.

We are one company with a real storefront at 10740 Wilshire Blvd in Westwood and our own mobile vans. When you call (213) 577-1366, you are not routed through a dispatch broker who sells your job to a stranger. The people who answer work with the people who show up. David, the owner and lead technician, oversees the work, which means there is a person behind the standards.

We answer the phone 24 hours a day, 7 days a week, year-round. A lock installation is often scheduled work, but sometimes it is not. If a break-in has damaged a door and it has to be secured tonight, or a new business opens tomorrow and the door has no lock, we can come out on a mobile locksmith visit and get it done properly.

Frequently asked questions

Can you install a lock I already bought?

Often yes. Tell us the brand and model when you call, and we will say whether it suits your door. If the lock is the wrong size, grade or style for the door, we will explain what we would change, and you can decide whether to use it or have us supply something else.

What is the difference between lock installation and lock replacement?

Installation means fitting a lock to a door that does not have that type of hardware yet, or adding a new lock somewhere. Replacement means removing a worn or damaged lock and putting a new one in its place. In practice the work overlaps, and we will tell you which description fits your door when you call. If you only want new keys on the same locks, see our page on lock rekeying.

Do you install mortise locks in older Monterey Park homes?

Yes. Mortise lock installation is common on older doors, and we can match an existing pocket or cut a new one. We measure the existing lock body first, because mortise sizes vary, and we may need to source the correct one.

Can you put a deadbolt on a door that only has a knob?

Usually, yes, as long as the door is thick enough and the edge is in good condition. We drill the additional bore, set the bolt and add a strike plate screwed into the framing. We cover that in more detail on our deadbolt page.

Which lock is best for a front door?

It depends on the door and your priorities. For most homes, a quality deadbolt paired with a handle set or lever, plus a well-secured strike plate, is a solid start. If security is a bigger concern, we can talk through higher-grade cylinders, and if you prefer keyless entry, we can explain smart locks. We will recommend based on what we see on the door, not on what is most expensive.

Do you handle commercial lock installation for restaurants and shops?

Yes. We install locks and related hardware on storefront, office and back-of-house doors for businesses in Monterey Park, including along Garvey Avenue and Atlantic Boulevard. Describe the door and how often it is used, and we will suggest hardware that suits that kind of use.

Will I need permission from my HOA or landlord?

Possibly. Condo associations often control exterior door hardware, and rental agreements usually limit what a tenant can change. Check with your association or landlord before we start. If you are a property owner and want help planning locks across several units, we can work with you on that.

How do I know your technician is legitimate?

Ask for the BSIS LCO license, which California requires locksmith companies to hold, from us or from any locksmith. You should also be able to get the company name, a callback number and a clear explanation of the work before it starts. Ours is (213) 577-1366, and you can reach us 24/7.

Can I book lock installation for a later date, or is it only for emergencies?

Both. We take planned installation work and urgent calls. Scheduling ahead is usually the more economical route because it avoids after-hours rates, but if you need a door secured right away, call any time and we will find a way to help.
