What does professional lock installation actually involve?
A new lock is only as good as the way it is fitted. The hardware can be excellent and still give trouble within a season if the bore is slightly off, the latch meets the strike plate at an angle, or the screws are too short to reach the framing behind the jamb. Most calls we get for lock installation in La Mirada come from a handful of situations: a remodel or addition with doors that have no hardware yet, an entry that never had a deadbolt, a worn set the homeowner wants to upgrade, a business opening or changing its doors, or someone who bought a lock at a hardware store and found the door does not match the instructions on the box.
Installation is different from replacing a broken lock or rekeying one you already own. Installing means working with the door itself: measuring, boring or routing where needed, checking the frame, and setting the hardware so it works every time without lifting, shoving or forcing the door. That is the part we spend our attention on, and it is the part that decides whether a lock still feels solid years from now.
If you are not sure whether you need an installation, a replacement or just new keys, call us and describe what you have. We will sort it out on the phone, and we will tell you plainly if a lighter-touch fix will do the job.
Which types of locks do we install?
The word lock covers a lot of different hardware, and the right choice depends on the door, the frame and what the door is protecting. Here is how we think about the main categories.
- Front door lock installation: usually a deadbolt paired with a handle set or a keyed knob or lever. We check that the door is thick enough and solid enough for the hardware you picked, then fit both pieces so they line up with the frame.
- Door lock installation for other doors: back doors, side gates into garages, office doors, bedroom privacy sets and utility rooms each want different hardware. A keyed entry set is not the same as a privacy set, and we match the function to the room.
- Lever lock installation: lever handles are easier to operate when your hands are full or your grip is limited, and many people simply prefer them to round knobs. We fit them on residential and commercial doors and set the latch so the lever returns cleanly.
- Mortise lock installation: a mortise lock sits in a deep pocket cut into the edge of the door, with the lock body, latch and often the deadbolt housed in one case. Where a door already has a mortise pocket, we can usually fit a new body of the right size without recutting. Where it does not, cutting a clean pocket is careful work that we do not rush.
- Security lock installation: higher-grade deadbolts, reinforced strike plates, longer screws and sometimes restricted keyways. If security is the main reason you are calling, see our page on high-security locks for how those options differ.
- Commercial lock installation: grade-rated cylindrical locks, mortise locks and storefront hardware for business doors. We cover that side in more depth on our commercial locksmith page.

Call (213) 577-1366How does a lock installation visit work, step by step?
Every door is a little different, so no two visits go exactly alike. This is the general sequence we follow whether the job is one front door or several doors at a business.
- You call (213) 577-1366 and tell us about the door: wood, metal, fiberglass, glass or aluminum storefront; roughly how thick it is; whether it already has holes drilled; and what kind of lock you want or already own.
- We schedule the visit and send a mobile van to your address in La Mirada. If the job needs a specific item we are unlikely to carry in the van, we say so on the call instead of surprising you at the door.
- The technician looks at the door and frame before touching anything: condition of the wood or metal, hinge sag, how the door sits in the opening, and whether the strike side is solid enough to hold new hardware.
- We talk through the options and explain the cost before any drilling starts. If something you chose does not suit the door, this is when we tell you.
- We mark and prepare the door using proper jigs and bits: boring the face and edge holes, or cutting a mortise pocket where the lock calls for one, and reinforcing thin or damaged areas where needed.
- We fit the lock, set the latch and deadbolt, and align the strike plate so the bolt throws fully into the frame. Strike screws go into the framing, not just the thin jamb.
- We test everything: the key from both sides, the handle, the latch and the bolt, with the door open and closed, several times. You get your keys and a quick explanation of how the hardware works and how to look after it.
What affects the cost of lock installation in La Mirada?
We do not publish flat numbers for installation because the same words can describe very different jobs. A fair estimate comes from the details below, and we walk you through them on the phone and again at the door.
- The lock itself: a basic keyed entry set, a heavier security deadbolt, a mortise lock body and a commercial-grade lever set sit at very different points on the cost scale, and brand and grade matter within each type.
- The door: solid wood, hollow-core, steel, fiberglass and glass doors all drill and hold hardware differently. Doors that are damaged, warped or already drilled in the wrong place take more preparation.
- New holes versus existing holes: swapping a lock into a prepared door is usually the lighter-cost route. Boring a new door or cutting a mortise pocket takes more time and more care.
- The frame: a strike plate needs solid wood or steel behind it. If the jamb is cracked or loose, reinforcement adds to the work.
- Number of doors and key setup: several doors fitted on one visit, or locks keyed alike so one key opens them all, change the scope of the job.
- Timing and travel: after-hours and holiday calls are handled differently from daytime appointments, and La Mirada is about 29 miles from our Westwood storefront, which is part of how a mobile visit is planned.
- Parts you supply: if you bought the lock yourself, we are happy to look at it first. Our labor still depends on the door, and we will say so if the hardware is a poor match.

Call (213) 577-1366Lock installation in La Mirada: tract homes, townhomes and the areas around Biola
La Mirada was master-planned and largely built out in the 1950s, and single-story ranch tract homes dominate the city. In the older tract streets, including the neighborhoods off Rosecrans Avenue, doors are often original or have been replaced a time or two, and the frames have had decades of seasons. When a home changes hands, new owners commonly want fresh hardware at the entry, whether that means a new deadbolt where there was only a knob, or a modern lever set on a door that has held the same lock for years. If all you need is new keys for existing locks, rekeying after a sale is usually the more economical route. If the hardware itself is tired or out of date, installing new locks is the cleaner fix.
Climate plays a part in how we fit locks here. La Mirada sits slightly inland of neighboring Gateway Cities and runs a few degrees warmer in summer, and seasonal heat can swell wood entry doors in the older tracts. A swollen door that rubs the frame will also fight a new latch, so we check how the door sits before we bore anything, and we set the latch and strike for the door as it actually is, not as it was when it was hung. The upside is that salt-air exposure here is negligible, so corrosion from coastal air is less of a worry for exterior hardware than it would be closer to the coast.
The Hillsborough and Knolls at Hillsborough area, toward the Puente Hills on the east side, tends toward newer and larger homes than the original tracts. Bigger entries and different door styles can change which hardware fits, so we measure the door rather than assume. In the La Mirada Landmark adult community and other condominium and townhome communities, entries are often controlled-access and managed by an HOA. Smart-lock installation in HOA townhome communities near La Mirada Regional Park is a good example of a local job: before we fit anything on an exterior door, we suggest checking your association's rules on exterior hardware. When you are ready, our smart lock installation page covers that side in detail.
Around the Biola University area, rentals and shared student housing mean owners and property managers sometimes need new locks fitted on interior and exterior doors, and tenants sometimes want a bedroom lock that works properly. Along the Foster Road corridor and elsewhere in the 90638 ZIP, a call usually starts with the same question: what kind of door is it, and what is it meant to protect? Answering that is where installation begins.

Call (213) 577-1366Commercial lock installation along Imperial Highway and Valley View Avenue
Retail centers along Imperial Highway and Valley View Avenue have their own hardware needs. Business doors are opened and closed far more often than a front door at home, so the lock needs to be built for repeated use, and the door must close and latch reliably every time. Storefront glass doors, aluminum frames and back-of-house steel doors each take different hardware and different fitting methods.
When we install commercial locks, we start with how the door is used. A back door that staff use all day may suit a lever set, while a storage room might need a keyed deadbolt or a mortise lock. We also consider how many people need keys and whether the business may later want a key system that grows with it. If your needs are bigger than single locks, our pages on commercial locksmith work and master key systems explain the next steps. For this page, the point is simple: the lock should suit the door and the way the business uses it, and it should be fitted so it keeps working.
Why call Wilshire Lock & Key for a new lock installation?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, La Mirada included. We run a real storefront at 10740 Wilshire Blvd in Westwood alongside mobile service vans, so you are dealing with a company that has a physical address, a shop and equipment, not a call center that passes your job to whoever is free. When you call, you reach us, and the same company that answers the phone sends the technician. There is no dispatch middleman between you and the person at your door.
David is the owner and lead technician, and he oversees how we approach installation work. That matters on a job like this, because fitting a lock correctly depends on small habits: checking the frame first, using the right bit, setting the strike properly and testing before leaving. Those habits are what we care about.
Our phone line, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round, so a door that will not secure at night or a business that needs a lock fitted before opening can get a real person. Our mobile locksmith service brings the tools and a range of hardware to you.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work starts and verify it with the state. It is a fair question to put to anyone who is going to drill into your door.

Call (213) 577-1366Do you need installation, replacement or something simpler?
People often call asking for one thing when another would serve them better, so here is how we separate them.
- New lock installation: the door has no lock in that position, or you want a different type of hardware from what is there now. This may involve new boring or a mortise pocket.
- Lock replacement: an existing lock is worn, damaged or failing, and a like-for-like swap into the same holes is the goal. See our lock replacement page.
- Rekeying: the lock works fine but you want a different key to operate it, for example after a move. That is a separate service with its own page on lock rekey work.
- Deadbolt only: if the question is just adding a deadbolt to a door that has a handle, our deadbolt installation page covers that in more depth.

Frequently asked questions
How long does a lock installation take?
It depends on the door. Swapping a new lock into a door that is already drilled is a quicker job. Boring a fresh door, cutting a mortise pocket or reinforcing a damaged frame takes longer. We do not promise a set time on the phone, but we can tell you what kind of job yours looks like once we know the door.
Can you install a lock I bought myself?
Yes, in most cases. We look at the lock first to make sure it suits the door and the frame. If it is the wrong size, a poor fit for the door or simply not built for the use, we say so before we start, and you can decide whether to go ahead or switch hardware.
Do I need a deadbolt as well as a handle on my front door?
Many front doors use both: a handle or lever with a latch for everyday use and a deadbolt for added resistance to forced entry. Some locks combine the two functions. We look at your door and how you use it, then recommend what makes sense instead of selling you more than you need.
Can you fit a new lock on a wood door that swells in the heat?
Yes. Seasonal heat can swell wood entry doors, especially in older tract homes, so we check how the door sits in the frame first. If the door rubs or binds, we set the latch and strike for the door as it actually is and tell you if the door itself needs attention.
What is the difference between a mortise lock and a regular door lock?
A regular cylindrical lock uses round holes through the face and edge of the door. A mortise lock sits inside a rectangular pocket cut into the door edge, with the lock body, latch and sometimes the deadbolt in one case. Mortise locks are common on older and commercial doors and require more careful fitting.
Do you do commercial lock installation in La Mirada?
Yes. We fit locks on business doors including retail and back-of-house doors, covering grade-rated levers, mortise locks and storefront hardware. The right choice depends on how the door is used and how many people need keys. We can talk through options by phone at (213) 577-1366.
Can new locks be keyed to work with my existing keys?
Often, yes. Keying a new lock to match an existing one depends on the brand and keyway, so we check what you have first. If a match is not possible, we can key several new locks alike so one key works on all of them.
Will installing a new lock damage my door?
A new lock needs holes in the right places, but done carefully it should not harm the door. Problems come from rushed drilling or mismatched hardware. We prepare the door properly, and if the door is already damaged or poorly prepared, we tell you what we find before we begin.
Can you come outside normal business hours?
Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. If a door will not secure or a business needs a lock fitted urgently, call and we will arrange a visit. After-hours work is planned differently from daytime appointments, and we explain how that affects cost on the call.
How do I know a locksmith is properly licensed?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for the license number before work begins and verify it with the state. It is a reasonable question, and any reputable company should be comfortable answering it.
