When does a Signal Hill door need a new lock installed?
Most new lock installation calls start from one of a few situations. A homeowner has bought a place and wants the entry hardware to match how they actually live. A landlord has a unit with a door that never got a proper lock. A business has moved into a space and the door carries whatever the last tenant left behind. Or a door has been forced, drilled or damaged and the old hardware is past saving.
Installing a lock is different from repairing or rekeying one. Installation means a lock is going onto a door that has none, or the old hardware is coming out and new hardware, often in a different style, is going in. That can mean boring new holes, cutting a mortise pocket, setting a strike plate into the frame, or adjusting the door so it closes true. If your current lock works and you only want new keys, rekeying the lock is usually the more economical route, and we will tell you so rather than sell you hardware you do not need.
We answer the phone at (213) 577-1366 twenty-four hours a day, so a door that cannot be secured tonight is a call we take tonight, not a message we return next week.
What kinds of lock can we install?
The phrase door lock installation covers a lot of different jobs. Here is how we sort them, so you can tell us what you have in mind or ask us to recommend something.
- Front door lock installation: keyed entry sets, handle sets paired with a separate deadbolt, and single-cylinder or double-cylinder setups where the door and local conditions call for them. The front door is the one people care about most, so it gets the most attention to fit and alignment.
- Lever lock installation: lever handles are easier on the hand than round knobs, and they are common on both home interiors and business doors. We fit lever sets for entry, privacy and passage use, and we set the latch backset and door prep correctly so the lever does not sag or bind.
- Mortise lock installation: a mortise lock sits inside a deep pocket cut into the edge of the door. Replacing one means matching the pocket size, faceplate and cylinder. Putting one into a door that has no pocket is real woodwork or metalwork and takes longer than a bored-hole lock.
- Security lock installation: higher-grade deadbolts, reinforced strike plates, longer screws that reach the framing, and cylinders chosen to resist picking and drilling. If that is your goal, our page on high-security locks explains the options.
- Deadbolts: a deadbolt is often the single most useful upgrade to a door. We cover this in detail on our deadbolt installation page.
- Electronic and keypad locks: if you want keyless entry, see our smart lock installation page, since those jobs involve batteries, app setup and door-prep questions that deserve their own explanation.

Call (213) 577-1366How we handle a lock installation, step by step
A good installation is mostly preparation. The drilling is quick; getting the door, the hardware and the frame to agree with each other is the real work. This is the order we follow.
- You call (213) 577-1366 and tell us the door type, what is on it now, and what you want. Photos of the door edge and frame help if you can send them.
- We come to you in a mobile van, or you can bring a door part or lock to our Westwood storefront at 10740 Wilshire Blvd if that is easier.
- We inspect the door on site: thickness, material, condition of the edge and frame, whether it hangs square, and whether the existing holes are standard sizes.
- We explain the options plainly, including which one is the lighter-cost choice and which one is the stronger choice, and where those are not the same thing.
- We prepare the door. That might mean template-marking, boring the cross-bore and edge-bore, cutting the latch mortise, or filling and re-drilling holes that are the wrong size.
- We install the lock body, the strike plate and the trim, and we use screws long enough to bite into the frame rather than just the thin jamb.
- We test it with the door open and then closed: the latch should catch without lifting or slamming, the bolt should throw fully, and the key and handle should turn without force.
- We hand over all keys, show you any settings or operating quirks, and leave the door the way we found it, cleaned up and secure.
What affects the cost of lock installation?
We do not quote prices on a web page, because the honest answer depends on the door in front of us. What we can do is tell you exactly what moves the cost up or down, so a quote from us, or from anyone else, makes sense.
The biggest factor is the lock itself. A basic residential lever set and a high-grade deadbolt with a restricted keyway are very different products, and the labor to fit them differs too. After that, door prep matters. A door that already has standard holes in the right places is a quick job. A door that needs new boring, a new mortise pocket, or repair of an earlier botched installation takes longer.
- Lock grade and type: standard, security-rated, mortise, electronic, or commercial-grade.
- Door material and condition: solid wood, hollow core, metal, glass or aluminum storefront stile, each with its own prep method.
- Number of locks: several doors in one visit usually make for a more efficient trip than separate calls.
- Frame condition: a split or worn jamb may need reinforcement before the strike plate will hold.
- Whether keys need to match: keying multiple locks alike, or matching an existing key, adds a step.
- Time and location of the call: after-hours work and travel to your address are part of the price, and we explain them before we start.

Call (213) 577-1366Residential and commercial lock installation: what differs
Residential lock installation is usually about balancing security with convenience. Families want a front door that locks securely but still opens easily with groceries in hand. Landlords want hardware that is durable and simple to rekey between tenants. Most home doors take standard bored-hole hardware, so the work centers on choosing the right grade and fitting it cleanly.
Commercial lock installation has different priorities. Business doors are used far more often, may have to meet egress rules, and sometimes sit in aluminum frames or heavy steel doors with their own hardware requirements. Function matters: a door may need to be locked from the outside but always free to exit, or hold open during business hours and lock at night. If your job involves a shop, office, dealership or industrial unit, our commercial locksmith work follows the same careful sequence, with added attention to door function and how many people share keys.
In both cases, we do not sell you hardware just to complete a sale. If the lock on your door is sound and the actual problem is a loose strike or a sagging hinge, we say so.
Lock installation across Signal Hill neighborhoods
Signal Hill is a small city sitting up on a hill above the surrounding coastal plain, and its housing is more varied than you might expect. Everything below uses facts about the area as we know them from our service data, and we apply it to what we see in actual lock work.
Lower on the slopes, the housing is modest cottages from the 1920s through the 1940s, a legacy of the oil boom. Doors that old have often been planed, re-hung and repainted many times. When we install a lock there, we look closely at whether the door still sits square and whether the edge has enough wood left to hold a modern bored lock. Sometimes the right job is a bit of repair to the door before the new lock goes in, not just a swap of hardware. Some of these doors may also carry older mortise-style hardware, and we assess that in person rather than guess.
Up top, the hilltop was redeveloped from the 1980s onward with view-home tracts, townhomes and gated developments. In the hilltop view-home district along Panorama and Skyline drives, the typical request is a lock upgrade or a new front door lock installation when a homeowner wants better security or a new style, often with a stronger deadbolt and a reinforced strike. In the gated Promontory at Signal Hill communities and the Eastbluff Estates area, residents often care about how entry hardware looks as well as how it performs, and any gate or access hardware is its own specialty, which we cover under gate lock repair.
Apartments cluster along Willow Street and Cherry Avenue, and the housing mix skews newer than the surrounding Long Beach blocks, including the blocks near California Heights. Landlords and property managers in the 90755 ZIP code often ask for new locks on unit doors, and we keep the keying simple so a rekey between tenants is easy later. Along the Spring Street corridor and in the Signal Hill Auto Center district on Cherry Avenue, installation work shifts to commercial and industrial doors, where the lock has to suit heavier use and the door itself.
Climate matters too. Signal Hill rises above the coastal plain, so it catches marine-layer damp and a steady onshore breeze. Exterior hardware here sees moderate salt exposure, less than beachfront Long Beach but not none. For exterior doors we favor hardware with durable finishes and ask you to think about which side of the door the weather hits. Signal Hill is roughly 29 miles from our Westwood storefront, and because we work from mobile vans we do the fitting at your door rather than asking you to bring it to us.

Call (213) 577-1366Why call Wilshire Lock & Key for installation?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. That long history is mostly a lot of doors: old, new, warped, drilled, painted shut. Those jobs teach you things that no catalog does.
We are one company with a storefront at 10740 Wilshire Blvd and mobile service vans. When you call (213) 577-1366, you are not reaching a call center that passes your job to whichever subcontractor is free. The same business that answers the phone does the work, and David, the owner and lead technician, oversees how we do it.
We answer every hour of every day of the year, so you can book installation for a convenient time or call us after a break-in when you need a door secured right now. For urgent after-hours work, see our mobile locksmith service, which is how we reach most Signal Hill customers.
One more thing worth knowing. California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. You should ask any locksmith, including us, for their license number before they start work on your door. A reputable company will give it without hesitation.
How to prepare before we arrive
You do not need to do much, but a few things save time and help us give you a straight answer.
- Know which door or doors you want done, and whether each is an exterior door, an interior door or a shared door.
- Take a photo of the door edge, the existing lock and the frame, if you can do so safely.
- Tell us if you already bought a lock. We can install it, but we will check that it suits the door and that it is a grade we are comfortable fitting.
- Clear the area around the door so we can work and test it.
- Tell us how many keys you need and who should have them, especially for rentals or shared buildings.
Frequently asked questions
Can you install a lock on a door that has never had one?
Yes. We bore the holes for the lock and latch, set the strike plate into the frame, and test it. The door needs enough thickness and solid material to take the hardware, and we check that on site before we begin.
What is the difference between lock installation and lock replacement?
Installation puts a lock where there was none, or changes to a different type of lock that needs new door prep. Replacement swaps like for like. If you only need a straight swap, see our lock replacement page.
Do I have to buy the lock first, or do you supply it?
Either works. We can supply hardware chosen for your door, or install a lock you already bought. If you buy first, tell us the brand and model so we can confirm it will fit your door and meet your security needs before we arrive.
Will a modern lock fit the older cottage doors on the lower slopes of Signal Hill?
Often yes, but we check first. Doors from the 1920s to 1940s may have been planed or repaired over the years, and some carry older mortise hardware. We look at thickness, edge condition and existing pockets, then explain what prep is needed.
Do you install locks for businesses in the Auto Center or along Spring Street?
Yes. Commercial lock installation is part of what we do for shops, offices, dealerships and industrial units. The door function, how often it is used and who holds keys all shape the choice of hardware.
Can you fit a mortise lock or a lever lock, not just a standard deadbolt?
Yes to both. Lever lock installation is straightforward on prepared doors. Mortise lock installation takes more care because the pocket size and faceplate must match, and we measure those on site before we begin.
Will salt air and coastal damp affect the lock I choose?
Signal Hill sits above the coastal plain and gets marine-layer damp and onshore breeze, with moderate salt exposure, less than beachfront Long Beach. For exterior doors we favor durable finishes, and we can explain which options suit your door's exposure.
How do I know a locksmith is legitimate before they work on my door?
California requires locksmith companies to hold a BSIS LCO license. Ask for the license number before work starts, and check that the company can name who is coming. A legitimate company will answer these questions without delay.
Can I book lock installation late at night or on a weekend?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. For non-urgent installs we can schedule a convenient time, and for a damaged door that needs securing now, we come as soon as we can.
