Lock installation in Northridge, CA

What does professional lock installation involve?

Lock installation means fitting a lock where there isn't one yet, or fitting a new one where an old one has been taken off: a front door, a back door, a side entry, an office suite, a storeroom. The lock itself is usually the simple part. What decides whether the job goes well is the door: the bore holes, the edge preparation, the latch alignment, the strike plate, and what the frame behind it is made of.

A lock that sits a fraction out of line will still turn on the day it goes in. Then it starts binding in the first stretch of summer heat, or it latches but leaves the bolt only partly engaged in the strike, which is exactly where a door gives way when someone leans on it. We install to avoid both outcomes.

This page covers door lock installation in Northridge: front door lock installation, residential lock installation, commercial lock installation, and the more specialized types such as mortise, lever, and security locks. If you're not sure which one you need, the next section will help sort it out.

Do you need a new installation, a rekey, or a replacement?

Plenty of calls start with 'I need a new lock' when the real need is something else. Getting this right at the start can save you money and a drilled door you didn't need. Here is how we sort it out:

• The door has no lock, or the lock prep is missing or damaged: that's an installation. This is common with new doors, added entry points, converted rooms, and doors where a previous lock was pried out.
• The lock works fine but you don't control who has keys: that's usually a job for lock rekeying. The hardware stays, the internal pins change, and old keys stop working.
• The lock is worn, broken, or you want a different style in the same door: that's a lock replacement, where the new unit goes into the existing holes.
• The new hardware doesn't match the old holes, or you're changing the type of lock entirely, for example going from a knob to a mortise lock: that's installation work, because the door has to be modified.

How we install a new lock, step by step

The order below is the one we follow on a typical door. Not every job needs every step, but none of them is skipped on a door that needs it.

1. We start with the phone call. We ask what kind of door it is, what it's made of, what's on it now, what you want it to do, and whether it's a home or a business. A photo of the door edge and frame helps if you can send one.
2. We inspect the door and frame on site. We check the door's thickness, any existing bores, the condition of the edge, whether the frame is solid, and whether the door hangs true or has sagged.
3. We confirm the hardware with you before anything gets drilled. That means the function (keyed entry, passage, storeroom, privacy), the finish, the handing on lever sets, and the grade of the lock for the way the door is used.
4. We prep the door. That means marking with a template, boring the face and edge holes with the right tools, and cutting the latch mortise. For a mortise lock, it also means cutting the pocket in the door edge.
5. We fit the lock body, latch, and trim, and set the backset so the handle and bolt sit where they should.
6. We set and reinforce the strike. The strike plate goes in with screws long enough to reach the framing, not just the thin door jamb, and we adjust it so the bolt throws fully without the door being lifted or pushed to engage it.
7. We test everything: keys, handles, bolt travel, and the door both open and closed. We check that the latch catches cleanly and the door doesn't rub in its frame.
8. We hand over the keys, show you how the lock works, clean up the shavings, and tell you plainly if anything about the frame or door is worth watching.

Which kinds of locks do we install?

Different doors ask for different locks. These are the main categories people search for, and what each one means in practice:

• Front door lock installation: usually a keyed entry lockset paired with a separate deadbolt. If you only need the bolt, see our page on deadbolt installation.
• Mortise lock installation: a mortise lock is a heavier lock body that sits inside a pocket cut into the door edge. You see them on older doors and on many commercial and storefront doors. They're more involved to fit, because the pocket has to be cut precisely and the door has to be thick enough to take it.
• Lever lock installation: lever handles replace round knobs. They're easier to operate with a full hand or a bad wrist, and they're common in offices, clinics, and shops, though plenty of homeowners choose them too.
• Security lock installation: higher-grade deadbolts, reinforced strikes, and restricted-key systems for doors that need more resistance. We cover the options on our high-security locks page.
• Electronic and keypad locks: if you'd rather have a keypad or app-based lock, that has its own steps and considerations, which we cover in smart lock installation.
• Commercial lock installation: storeroom functions, office entry sets, and exit hardware matched to the door. For the wider range of door hardware, see commercial door hardware.

What affects the cost of lock installation in Northridge?

We don't quote numbers on a web page, because the same phrase 'install a lock' covers very different jobs. What drives the cost is fairly predictable, though, and we'll walk through it with you before work starts.

• The hardware itself: a basic residential lockset and a high-grade or commercial-grade lock are very different products, and finish and brand change things too.
• The number of locks: several doors keyed alike takes more time than one door, but there are efficiencies in doing them together.
• The door material: solid wood, hollow-core, steel, and aluminum storefront doors all take different tools and different care.
• Whether the door is already prepped: a door with the right holes in the right places is a quicker job than one that has to be bored from scratch.
• The state of the frame: a split jamb or loose strike area needs repair or reinforcement for the new lock to do its job.
• The type of lock: a mortise lock with a pocket to cut is more work than a standard bored lockset.
• Timing and location: calls outside normal hours and jobs farther from our base take more effort to staff and reach.

What does lock installation look like in Northridge homes and apartments?

Northridge is a mix of 1950s and 1960s ranch tracts and student-oriented apartment complexes concentrated around the CSUN campus. That mix shapes what we run into on installs across ZIP codes 91324 and 91325.

In the ranch tracts, such as those in the Devonshire Street corridor, homes are decades old and have often seen several generations of hardware. When we're adding or changing a lock on a door like that, we look at the old bores and the frame first, because a door that has had locks swapped over the years may need more care than a new one. Toward the western edge near Sherwood Forest, larger semi-rural lots often mean more doors to think about: side entries, detached structures, and gates that sit apart from the main house.

Around the CSUN campus area, the picture is different. Student apartments see high turnover, and hardware in high-turnover units wears faster. Semester move-in and move-out are when a lot of locks get used hard and when a lot of lockout calls come in. Property owners adding or upgrading locks between tenants should read our page on locksmith services for landlords, which covers that side of the work.

The neighborhood also gave its name to the 1994 earthquake, and much of the multifamily stock was repaired or rebuilt afterward. The result is that door frames and hardware vary widely in age, even within one complex. We don't assume a frame is sound just because the building looks fairly new. We check it before we promise a fit.

Then there's the weather. North Valley summers are long and hot, and fall brings Santa Ana wind events. Sun-exposed doors expand in the heat, so we pay attention to clearance and alignment on west- and south-facing entries, because a lock that fits perfectly in the cool of the morning can bind in the afternoon. Our base is on Wilshire Boulevard in Westwood, roughly 20 miles from Northridge, and our mobile vans make the trip.

What about commercial lock installation in Northridge?

Businesses in Northridge have different needs from homes, and they don't all look alike. Retail in the Northridge Fashion Center district tends to involve storeroom and back-of-house locks and keying that works for more than one person. Medical offices near Dignity Health Northridge Hospital Medical Center have their own concerns about who can get into which room. Shops and offices along the Reseda Boulevard corridor often need entry locks that stand up to daily use.

For a commercial door, we match the lock function to how the door is used: who needs access, whether the door has to be locked from the inside, and how the lock fits with the exit and hardware requirements for that door. If you have several doors and want one key to open some of them but not others, the right answer may be a master key system planned from the start, not a pile of separate keys added over time. It's much easier to design that before the locks go in than to rework it later.

If you need us after hours because a door can't be secured, call. The phone is answered around the clock.

Why call Wilshire Lock & Key for installation?

We've been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Northridge among them. We're a real company with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, not a call center that hands your job to whoever's nearest.

When you call (213) 577-1366, you're reaching the company that does the work. There are no dispatch middlemen between you and the technician. David, the owner and lead technician, oversees our work, which matters on installs because the details that make a lock last are the ones nobody sees after the job is finished.

We'll tell you honestly when you don't need an installation, and when a rekey or a repair makes more sense. We'd rather lose a job than do the wrong one.

How do you check a locksmith's license in California?

California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Before anyone drills into your door, ask for the company's license number. A legitimate company will give it to you without hesitation, and you can check it with the state.

Ask any locksmith the same questions: who will actually do the work, where the company is located, and whether the quote you were given will change when they arrive. Those answers tell you a lot. We're glad to answer all of them for you, so just ask when you call.
