What does a proper lock installation actually involve?
Putting a new lock on a door sounds like a ten-minute screwdriver job, and on a clean, well-prepared door it can be quick. But most of the work that decides whether a lock lasts is in the door itself, not the lock. The bore hole has to be the right size and cut square. The latch has to line up with the strike plate so the bolt throws freely without dragging. The backset, which is the distance from the door edge to the center of the lock, has to match the hardware. And the strike has to be anchored into the framing, not just the thin trim around the jamb.
When a lock is installed badly, you notice it slowly. The key gets stiff in the afternoon heat. The bolt only catches if you lift the door while turning. The handle sags after a few months. People often blame the lock and buy another one, when the real problem is a door that was never prepared correctly. Our job on a lock installation is to make the lock, the door and the frame work together as one assembly.
This page covers new installations: a door that has no lock yet, a door being upgraded to different hardware, or a new door that needs to be fitted out. If you are swapping an existing lock that still fits, our lock replacement service is the closer match, and we will point you there if that is what your door needs.
Which type of lock does your door need?
Most people call us knowing they want a lock, but not which kind. That is a reasonable place to start, and a short conversation usually sorts it out. The right choice depends on the door material, its thickness, how the door is used and what you are protecting. Here are the types we install most often and where each one fits.
- Front door lock installation: usually a deadbolt paired with a handle set or knob, so the door has a latch for everyday use and a separate bolt for real security. Our deadbolt installation page goes deeper on the bolt side.
- Lever lock installation: lever handles are easier on hands than round knobs and are common on interior doors, accessibility-minded entries and many commercial doors. A lever should be fitted so it does not droop or catch on trim.
- Mortise lock installation: a mortise lock sits in a rectangular pocket cut into the edge of the door, and it is common on older and heavier doors and on commercial entries. It needs careful chisel work, so it is not something to improvise.
- Security lock installation: higher-grade deadbolts, reinforced strikes and longer screws, chosen for doors that need to resist force. Where a door needs pick or drill resistance, we will talk about high-security locks.
- Keyed entry sets, privacy sets and storeroom locks: different functions for bedrooms, bathrooms, offices and supply rooms, each with a different mechanism inside.

Call (213) 577-1366How do we install a new lock, step by step?
Every door is a little different, but the sequence we follow stays the same. We do not rush the early steps, because mistakes there cannot be hidden later.
- We talk it through on the phone. When you call (213) 577-1366, we ask about the door material, thickness, whether it has existing holes, and what the lock is for. That lets us bring the right hardware in the van.
- We inspect the door and frame on site. We check for swelling, warping, old filled holes, a loose or split jamb, and whether the door closes true before any drilling starts.
- We confirm the hardware fits. Door thickness, backset, bore diameter and edge-bore size are measured so the lock matches the door instead of being forced into it.
- We prepare the door. That means marking, drilling the face bore and edge bore square, and cutting the mortise or latch recess to the right depth. On wood doors we keep splintering to a minimum.
- We mount the lock and strike. The latch is set, the lock body fitted, and the strike plate installed on the jamb with screws long enough to reach the framing behind it.
- We test and adjust. The bolt should extend fully, retract smoothly and engage the strike without any lifting, pushing or slamming. We run the key and the handle many times, with the door open and closed.
- We key it to your needs. If you want several locks on one key, we set that up. You get your keys, and we show you how the lock operates before we leave.
Residential and commercial lock installation: what changes?
Residential lock installation is mostly about fit, comfort and security for a household. Front doors, back doors, garage entry doors, side gates and bedroom or office doors each want a different function, and families usually want the entry doors keyed alike so one key does the job. Finishes matter too, since the hardware is something you see and touch every day.
Commercial lock installation adds other priorities. Business doors are used far more often, so the hardware needs to be built for heavy cycling. Many commercial entries use mortise locks, narrow-stile aluminum doors, or exit devices, and each needs its own preparation method. There may also be fire-code and egress requirements about how a door must open from the inside, which we respect when selecting hardware. Keying is often more involved, with several staff needing access to different areas. If you are fitting out a whole business, our storefront lock repair page covers what we do for older glass-and-aluminum entries, and we can plan new hardware at the same visit.
If you are not sure which side of the line your property falls on, such as a home office, a rental unit or a workshop at the back of a house, just describe it. We will work out the right hardware for how the door is actually used, not for what category it falls in.

Call (213) 577-1366What affects the cost of lock installation in Santa Paula?
We do not quote a number over the phone for work we have not seen, and you should be cautious of anyone who does. What we can do is explain what moves the cost up or down, so you can judge any quote you receive.
The lock itself is the biggest variable. A basic keyed knob and a high-grade deadbolt with a reinforced strike are very different products. A smart lock or a mortise set sits further up the range again. The usually more economical route is a solid, mid-grade lock correctly installed, rather than the most expensive one installed poorly.
- Hardware grade and type: standard, high-security, mortise, lever, smart or commercial-rated.
- Door condition: a new, square, pre-bored door is quick; an older door that needs re-boring, patching or squaring up takes longer.
- Door material: solid wood, hollow-core, steel, fiberglass and aluminum each need different tools and care.
- Number of locks: several doors keyed alike is usually more efficient per door than one-off visits.
- Keying: simple single keys versus keyed-alike sets or a larger key hierarchy.
- Frame repair: if the jamb is split or the strike area is weak, reinforcing it is part of making the lock actually work.
- Time and distance: after-hours calls and travel to your location can affect the total, and we tell you how we price this before we begin.
Lock installation across Santa Paula: what we see locally
Santa Paula is about 62 miles from our Westwood storefront, so we plan our drive carefully and give you an honest arrival window when you call, rather than a guess. Our mobile vans carry a wide stock of locks, bore tools and strike hardware so most installations can be finished in a single visit at your door.
Around Downtown Santa Paula and the Main Street district, the housing is early-1900s Victorians and Craftsman bungalows, with postwar ranch homes on the blocks around them. These older doors are often solid wood, sometimes thicker or thinner than modern standards, and they have been drilled and re-drilled over the decades. A new front door lock installation here often starts with reading the door: filling an oversized old bore, choosing a deadbolt that suits the character of the house, or fitting a mortise set where the door was originally made for one. Heat cycles swell wood doors in the valley's hot, dry late summers, so we leave sensible clearance and check that the bolt still throws when the door is at its tightest.
In the east side's Harvest at Limoneira, new single-family tract homes are going in. Builder-grade hardware on new doors is common, and new owners frequently want better locks and keyed-alike entries before they move in. That is a natural fit for lock installation: stronger deadbolts on the front and garage entry doors, and, where the owner wants it, our smart lock installation service. Because the doors are new and square, these installs are typically straightforward.
Out toward the Santa Paula Airport area and the SR-150 corridor near Steckel Park, the work shifts. Shops, hangars and outbuildings, and working citrus ranches at the city's edges, need locks that handle dust and outdoor conditions. Agricultural dust can work into exterior locks, so we favor sealed or weather-resistant hardware and recommend a little dry lubricant rather than oil, which holds grit. For ranch gates specifically, see our gate lock repair page.
Whichever part of 93060 you are in, you get the same process: look at the door first, choose the lock second, and test before we leave.

Call (213) 577-1366Why call Wilshire Lock & Key for a new lock installation?
We have been in business since 1987, and that is a lot of doors. Since then we have worked on old wood doors that do not match any modern template, tract-home steel doors, and commercial aluminum frames. That background is why we are comfortable when a door turns out different from what was described on the phone.
We are one company. When you call (213) 577-1366, you reach us, not a dispatch service that sells your job to whichever contractor answers. The technician at your door works for the same company you called, and David, the owner and lead technician, oversees how we work and what gets installed. We run a storefront at 10740 Wilshire Blvd in Los Angeles plus mobile service vans, so we can stock hardware and send it to you.
We answer the phone 24 hours a day, 7 days a week, all year round, and we serve 140 cities across Los Angeles and Ventura counties. Santa Paula is one of them, and our mobile locksmith service is how we get to you.
What should you have ready before we arrive?
A little preparation makes the visit quicker and the result better. None of this is required, and if you are not sure about something we will figure it out on site.
- The door's material and approximate thickness, or a photo of the door edge.
- Whether you are installing on a bare door, replacing hardware or fitting a brand-new door.
- How many people need keys, and whether you want entry doors keyed alike.
- Any hardware you have already bought, so we can check it fits before we drill.
- Access to the door and a clear area around it; for gates or outbuildings, tell us how to get to the location.
- Photos of the door and frame, if you can send them, especially when the door is old or damaged.
How do you know a locksmith is properly qualified?
California requires locksmith companies to hold a license issued by the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are considering for their license number, and check that it is current with the state. That applies to us and everyone else. A real company will give you the number without hesitation.
Beyond paperwork, a few things are worth watching. Be wary of a company that will not tell you its name, one that quotes a very low figure on the phone and then changes it at the door, or one that cannot say where it is based. We have a physical storefront and a number you can call back, and we are happy to explain our work before we start. If you are still comparing options, our Santa Paula locksmith page gives an overview of what we do in the city.
Frequently asked questions
What is the difference between lock installation and lock replacement?
Installation means fitting a lock where there was none, or fitting a different type of lock that needs the door to be prepared, such as adding a deadbolt or converting to a mortise set. Replacement means removing a worn or damaged lock and putting a matching one in the same holes. Many jobs are a mix of both, and we will tell you which applies when we see the door.
Can you install a front door lock on an older Craftsman or Victorian door?
Yes. Older wood doors are common around Downtown Santa Paula, and we work on them regularly. We check the thickness, look for old repairs, and choose hardware that fits the existing preparation where possible. If the door needs re-boring or patching, we explain that before drilling.
Do you install mortise locks and lever locks?
We install both. Mortise locks need a rectangular pocket cut in the door edge and should be fitted carefully, particularly on older or commercial doors. Lever locks are straightforward on most doors once the bore and backset are confirmed. If a mortise body is no longer available, we will explain the alternatives.
How long does a lock installation take?
A single lock on a door that is in good shape is usually a short job. Doors that need re-boring, frame reinforcement, or several locks keyed alike take longer. We will give you a realistic idea when we see the door, and we tell you the arrival window when you call.
Can you install locks on commercial doors and storefronts in Santa Paula?
Yes. We handle commercial lock installation including mortise sets, lever handles and entry hardware for businesses, including shops along the Main Street district. For heavy-duty hardware options, see our page on commercial door hardware.
Will a new lock work if my wood door swells in summer heat?
A properly fitted lock should. Santa Paula's hot, dry late summers can swell older wood doors, so we leave sensible clearance and check the bolt at the door's tightest. If the door itself rubs or binds, the fix may involve the door, not the lock, and we will say so.
Can you key all my new locks to one key?
Yes, entry locks can usually be keyed alike so one key opens the front, back and garage doors. Tell us how many doors and how many people need keys. If you already have locks you want to match, we can often rekey them to fit; see our lock rekeying page.
Do you offer lock installation at night or on weekends?
Yes. We answer the phone 24 hours a day, 7 days a week, including holidays, at (213) 577-1366. Some installations are better done in daylight so we can see the door properly, but if you need your home or business secured at night, we will work out the best approach.
