What does professional lock installation actually involve?
Most people think installing a lock is a ten-minute swap: pull the old one, drop in the new one. Sometimes it is. More often the work is in the door, not the lock. A lock only performs as well as the hole it sits in, the edge it latches into, and the strike plate it meets on the frame. If the bore is slightly off, the bolt drags. If the frame is soft or the screws are short, the strongest deadbolt on the shelf can be kicked through with one hard shove.
That is why we treat lock installation as carpentry and hardware work together. We look at the door first: its material, its thickness, its condition, how it hangs, and what it is protecting. Then we choose hardware that fits that door and that household or business, and we fit it so it turns smoothly, latches without persuasion, and locks the way it should every time.
This page covers new lock installation: adding a lock where there is none, fitting a new lock on a new or remodeled door, and putting in hardware you have already bought. If your existing lock still works and you only need different keys, that is a different job, and you will want our lock rekey service instead, which is usually the more economical route.
Which types of locks do we install in Temple City?
We install the full range of residential and light commercial hardware. Here is how the common categories break down and where each one earns its place.
- Front door lock installation: a keyed entry set or a deadbolt with a matching handle set, fitted to the door people actually use every day. This is the lock that gets the most wear, so fit and alignment matter most here.
- Door lock installation for interior and secondary doors: back doors, side doors, garage entry doors, and doors to offices or storage rooms. Each has different needs, from a simple keyed knob to a full deadbolt.
- Lever lock installation: lever handles instead of round knobs. They are easier on hands and wrists, they are common in commercial spaces, and many owners choose them for accessibility in a home.
- Mortise lock installation: a mortise lock sits in a deep pocket cut into the edge of the door rather than a simple round bore. You find them on older, heavier doors and on many commercial entries. They are strong, but the installation is exacting.
- Security lock installation: higher-grade deadbolts, reinforced strikes, and pick- and drill-resistant cylinders where the situation calls for more than a standard builder lock.
- Residential lock installation and commercial lock installation: the same skills, different priorities. Homes tend to prioritize convenience and appearance. Businesses add code, traffic, and key control into the mix.

Call (213) 577-1366How we install a lock, step by step
Every door is a little different, but the process below is what you can expect when we arrive, whether we meet you at a house or a storefront.
- We look at the door and frame before touching any hardware. We check the door's thickness, whether it sticks or sags, how the frame is built, and where the old hardware sat, if any.
- We talk through what you want the lock to do. Who needs keys, whether you want a keypad or smart option, whether this is a main entry or a secondary door, and what level of security makes sense for the location.
- We recommend hardware that fits the door and the use. If you have already bought a lock, we check that it suits the door and tell you plainly if it does not.
- We prepare the door. That can mean drilling or enlarging the cross bore and edge bore, cutting or deepening a mortise pocket, or chiseling out a clean recess for the latch plate. We work to the template for the lock, not by eye.
- We fit the lock, then set the strike plate on the frame so the bolt lands dead center. On deadbolts we use longer screws that reach the framing behind the jamb, not just the thin trim.
- We test it with the door open and closed, from both sides, with every key. The bolt should throw fully with no dragging, and the latch should catch without a slam.
- We hand over the keys, explain any settings on keypad or smart models, and point out anything about the door itself that you may want to address later.
Front door lock installation on older Temple City homes
A lot of Temple City's housing is postwar: 1940s and 1950s bungalows and ranch houses on modest lots. Many of those front doors are solid wood and have been in service for decades. The original hardware is often worn, loose in the door, or a single keyed knob with no real deadbolt behind it. Installing a modern entry lock on a door like that is a common job for us, and it takes more care than a new door would.
The climate plays a part. The central San Gabriel Valley gets hot, dry summers with very little marine influence this far inland, and those seasonal heat swings make wood doors expand and sometimes stick. A lock fitted too tight in July may bind, and a lock fitted in cooler months may feel loose in the heat. When we install on a wood door we pay attention to how the door moves, check where it rubs, and set the bolt and strike with enough tolerance to work through the seasons. If the door itself is binding badly, we will tell you, because a new lock will not fix a door that is fighting its frame.
Older doors also sometimes have previous holes from earlier hardware. We can often work with those, or cover them cleanly with the new lock's trim, so you do not end up with a patchwork of drilled circles on the door face.

Call (213) 577-1366Mortise and lever lock installation: why it is a different skill
Mortise lock installation is not a swap you can do with a drill and a screwdriver. The lock body is a rectangular box that sits inside a pocket cut into the edge of the door. That pocket has to be the right depth and width, and the faceplate has to sit flush. Cut it too wide and the door weakens. Cut it off-line and the handle will not line up with the spindle. Because mortise bodies are heavy and the pockets are large, the door itself has to be sound enough to carry them.
Lever lock installation, on the other hand, is often a straightforward upgrade from a knob, if the door has the standard bore. But there are details that matter. Levers need to return to the horizontal position properly, and they sag over time if the internal spring is weak or the rose is not seated correctly. On commercial doors, lever hardware is often chosen for accessibility, so the handing, the backset, and the function (passage, privacy, storeroom, entry) all need to be right.
If you are unsure which function you need, tell us what the door is for and who should be able to open it from each side. We will match the function to the use rather than guess.
Residential versus commercial lock installation
Residential lock installation usually starts with the question of how the household lives. Do kids come and go? Do you want one key for every door? Is there a pet door, a side gate, a garage entry that gets used more than the front? We try to keep the number of keys down and the hardware consistent, so that daily life stays simple.
Commercial lock installation adds layers. A business door may need to open freely from the inside for safe exit while staying locked from the outside. It may need hardware that handles hundreds of cycles a day. It may need a keying plan so that staff, a manager, and the owner have different levels of access. For anything in that range, our commercial door hardware service goes deeper into the closers, exit devices, and heavy-duty sets that go with a business door.
The line between the two blurs in small apartment buildings and mixed-use properties, which is common in places like the Las Tunas Drive and Rosemead Boulevard areas of Temple City. A unit door is residential in feel but may need to coordinate with a building keying approach. If you are a property owner dealing with several doors, tell us up front so we can plan keys and hardware to match rather than treating every door as a one-off.

Call (213) 577-1366Lock installation around Temple City: what we see where
The housing here splits in an interesting way. Strong demand tied to the Temple City Unified School District has driven teardowns and larger two-story rebuilds since the 2000s. So you can drive a single street and see a worn 1950s bungalow next to a brand-new house with builder-grade locksets. Those two ends of the spectrum need different things from a locksmith.
On the postwar blocks near Temple City Park and around Live Oak Park, the typical request is to replace tired hardware and fit a proper deadbolt where one was never installed. On rebuilt two-story homes on the north side near the Arcadia border, the doors are newer but the locks are often the basic sets the builder chose. Owners ask us to install better entry hardware on the front door, add a keyed deadbolt to the side and garage doors, and sometimes put in a matching set so all exterior doors work from one key.
Near Longden Avenue, a number of homes have been remodeled, and those owners often want smart lock installation as part of the update. The door is usually a modern slab, the finish matters, and the owner wants a keypad or app-based lock that matches the new hardware. We handle that on our smart lock installation page in more depth, but the physical installation, the bore, the backset, and the strike, is the same careful work described above.
Downtown along Las Tunas Drive and near the Camellia Square area, many of the doors belong to small shops, offices, and the apartment or condo buildings that cluster nearby. The Rosemead Boulevard and Temple City Boulevard corridors are the same story: a mix of storefronts and small multi-unit buildings. Installing a new lock on a ground-floor commercial door in these areas means thinking about foot traffic, visibility, and how the door closes in a busy setting. Everything we do in the 91780 ZIP code starts from that kind of practical read of the door in front of us.
What affects the cost of lock installation in Temple City?
We do not quote numbers on a web page, because the honest answer depends on the door and the hardware. What we can do is tell you exactly what moves the cost up or down, so there are no surprises when you call (213) 577-1366.
The main factors are the following.
- The lock itself. A basic keyed knob, a Grade 1 commercial lever, a high-security deadbolt, and a smart lock are in very different categories. You can supply your own hardware or we can recommend and provide it.
- The condition of the door and frame. A clean, standard-bore door is straightforward. A door that needs new holes drilled, a mortise pocket cut or repaired, or a damaged jamb reinforced takes more time and sometimes extra materials.
- The number of locks. Fitting one door is a single job. Fitting every exterior door on a house, ideally keyed alike, is more work but usually more economical per door, since it is one visit.
- Lock type and complexity. Mortise lock installation takes more skill and time than a standard cylindrical set.
- Time and place. Service during standard daytime hours is different from a call in the middle of the night, and distance from our Westwood storefront can play a part for outlying areas.
- Extras. Reinforcing strike plates, longer screws, door edge guards, or keying multiple locks to one key are all add-ons that raise the scope slightly and often raise the real security of the door the most.

How to choose a locksmith for installation work
Fitting a lock is a trust job. You are letting someone work on the door that protects your home or business and handing over the keys. In California, locksmith companies are required to hold a license from the Bureau of Security and Investigative Services (BSIS), known as a Locksmith Company (LCO) license. Ask any locksmith you are considering for their license number, and check it with BSIS before you book. That is good advice whoever you call, including us.
Beyond licensing, a few other things are worth asking. Will the quote cover the full job, including any door preparation? Will the technician explain what they are installing and why? Will you get all the keys and any codes at the end? A good locksmith answers those questions plainly, without pressure, and does not try to upsell hardware the door does not need.
If your concern is a higher level of protection, such as a pick-resistant or drill-resistant cylinder, take a look at our high-security locks page. If you are adding a deadbolt to an existing entry, our deadbolt installation page covers that job on its own. For landlords who need several doors done consistently, see our locksmith for landlords service.
Frequently asked questions
How long does a lock installation take?
A standard lock on a door with an existing bore is usually quick. Doors that need new holes, a mortise pocket, or frame reinforcement take longer. When you call (213) 577-1366, describe the door and we will give you a realistic sense of the job before we arrive.
Can you install a lock I already bought?
Yes. We will check that it fits your door's thickness, bore, and backset, and tell you honestly if it is not a good match. If it is a sound lock, we install it properly, including setting the strike plate and testing it.
What is the difference between a lock installation and a rekey?
Installation puts new hardware on a door. Rekeying changes the internal pins of a lock you already have so it works with a different key. If your current lock is in good shape and you only need new keys, a rekey is usually the more economical choice.
Do you install locks on older wood doors that stick in summer?
Yes, and it is common here. Wood doors expand in the heat and can bind. We check how the door moves, set the bolt and strike with enough tolerance, and tell you if the door itself needs planing or adjusting so the new lock is not blamed for a door problem.
Can you install a mortise lock on my door?
If the door is thick and sound enough, yes. Mortise installation involves cutting a deep pocket in the door edge, so we inspect the door first. If the door is too thin or damaged, we will explain the options before we cut anything.
Do you handle commercial lock installation for shops and offices?
Yes. We fit locks on storefront, office, and back-of-house doors, including lever sets and heavier commercial hardware. Tell us about the door's traffic and exit needs when you call so we bring the right hardware.
Can you key all my new locks to one key?
In most cases, yes. Keying several exterior locks alike is a common request for homes and small buildings. It reduces the number of keys you carry and is usually more economical than separate keys for each door.
Do you install locks at night or on weekends?
Yes. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. If a door will not secure and it cannot wait, call and we will work out the right plan with you.
How do I know a locksmith is properly licensed in California?
California requires locksmith companies to hold a BSIS Locksmith Company license. Ask any locksmith for their license number and verify it with the Bureau of Security and Investigative Services before they start work.
