What does lock replacement actually involve?
Lock replacement means taking the old hardware off your door and fitting new hardware in its place: the knob or lever, the deadbolt, or both, along with the strike plate and any trim that goes with them. The door itself stays. What changes is the part that decides who gets in.
Most people call us for one of a few reasons. The lock is damaged, maybe from a forced-entry attempt, a kicked door, or a latch that finally snapped. Or it is worn, and the key sticks, the cylinder spins loose, or the bolt only throws if you lift the door and lean on it. Sometimes the hardware is just outdated: a builder-grade lock from decades ago, a lock whose keys have been copied too many times to count, or a door with no deadbolt at all. And sometimes it is the day after a move, when you realize you have no idea who holds a key to the place.
If you are standing outside a locked door right now, that is a lockout, not a replacement, and it has its own page: house lockout help in Glendale. Often we can get you in first and talk about replacing the lock afterward, once you are not stuck on the porch.
Should you replace the lock or just rekey it?
This is the question we ask ourselves first at every job, because the honest answer is not always replacement. A lock that works smoothly and is made by a reputable manufacturer often does not need to go in the trash. If your only concern is who has keys, changing the inside of the lock so old keys stop working is usually the more economical route. We cover that on our lock rekey page.
Replacement makes more sense when the hardware itself is the problem. A few quick ways to tell:
- Replace when the lock is physically damaged: bent bolt, cracked housing, a cylinder that has been drilled, pried, or hammered.
- Replace when the mechanism is worn out and no longer turns cleanly, or when parts are no longer available.
- Replace when the lock is a weak design and you want a real security lock upgrade, not just new keys.
- Rekey when the lock is sound and you only need to cut off old key holders, such as a former tenant, contractor, or roommate.
- Repair when one small part is the issue, like a loose handle or a sticking latch. That is a different job, covered under lock repair.

Call (213) 577-1366How we replace a lock, step by step
A replacement is not complicated work, but small details decide whether the new lock feels solid for years or starts giving you trouble in a month. Here is how a typical visit goes.
- You call (213) 577-1366 and tell us what is happening: which door, what is wrong with the lock, and whether it is a home, an apartment, or a business. The line is answered 24 hours a day, so a broken lock at night gets the same attention as one at noon.
- We come to you in one of our mobile vans. If you would rather browse hardware in person, our storefront at 10740 Wilshire Blvd in Westwood is open to you too.
- The technician looks at the door before touching the lock. We check the door thickness, the bore holes, the edge, the strike plate, and the frame, since a new lock in a damaged frame is still a weak door.
- We talk through your options in plain terms: what will fit the existing holes, what would need modification, and what the realistic difference is between lighter-cost hardware and heavier-duty hardware. You decide.
- We remove the old lock and fit the new one, aligning the bolt and latch so they move freely without forcing the door. We reinforce the strike plate where it makes sense, since a lot of break-ins defeat the frame, not the lock.
- We test everything with the door open and closed, hand you the new keys, and show you any features you need to know about. If you asked for matching keys across several doors, we set that up before we leave.
What affects the cost of lock replacement in Glendale?
We do not quote numbers on a web page because the real figure depends on your door, and a number written without seeing it would be a guess dressed up as a promise. What we can do is tell you exactly what moves the cost up or down, so nothing surprises you when the technician gives you the quote.
- The hardware itself. A basic knob set, a standard deadbolt, a high-security cylinder, and an electronic lock sit in very different cost tiers.
- How many locks. Replacing one front door lock is a different job from replacing every exterior lock on a house, and doing several at once usually makes more sense per lock.
- Whether keys should match. Keying all your doors alike is convenient, and it affects how the hardware is ordered or set up.
- Door and frame condition. Fitting new hardware to a door that is warped, cracked, or has oversized or damaged holes can require extra work.
- Door type. Wood, metal, glass-panel, and aluminum storefront doors all call for different hardware and different handling.
- Time of day. A late-night or holiday call involves different staffing than a daytime appointment, and we are upfront about that before we start.
- Distance. Glendale is roughly 18 miles from our Westwood base, and travel is part of the picture for any mobile job.
- Added security work, like reinforcing a strike plate or upgrading a deadbolt to something harder to attack.

Call (213) 577-1366Replacing locks on apartments, condos, and rentals
Apartment lock replacement has a few wrinkles that a house does not. If you rent, check your lease before changing hardware, and tell your landlord or property manager what you plan to do. In many buildings the management needs a working key, and some leases specify who pays for lock changes. A technician can swap the lock quickly, but the paperwork question belongs to you and your landlord.
Glendale has a dense apartment and condo core south of downtown, and a lot of those doors have seen decades of tenants. When a unit changes hands, replacing the lock is often cleaner than tracking down every old key. If you manage several units, our locksmith services for landlords can help you keep turnovers consistent, with doors keyed the way you need.
Condo buildings add another layer. Many have shared entry systems, lobbies, or association rules about what hardware is allowed on unit doors. We will tell you what we can replace on your own door and where the building's own system takes over, so you do not buy something the association will make you remove.
Business lock replacement and security upgrades
Commercial lock replacement is not the same as residential work with bigger doors. Business doors take heavier traffic, the hardware often has to meet different requirements, and a broken lock can leave a shop or office unable to close up safely. Glass storefront doors, steel back doors, and doors with panic hardware each need their own approach.
For a business security upgrade, we start by looking at how the doors are used. Who needs keys, how many people open and close, whether former employees still have access, and whether the back door is as strong as the front. Sometimes the answer is straightforward replacement of worn cylinders and deadbolts. Sometimes it is moving to a keying plan where each person gets a key that fits only what they need. Our commercial locksmith services cover the broader range of business work, and lock replacement is often the first practical step.
If you run a storefront, tell us whether the door is glass, aluminum, or solid, and whether it has a closer or exit device on it. That detail changes the hardware we bring.
Lock replacement in Glendale: hillside homes, revival houses, and the flatlands
Glendale is not one kind of housing, and the right replacement depends on which kind of door you have. We serve every ZIP in the city, from 91201 through 91208 and 91020, and the work changes a lot from block to block.
In Rossmoyne and Adams Hill, many homes are 1920s Spanish and Tudor revival houses. Those doors are often solid wood with older mortises and bore holes that were never meant for modern hardware. A replacement there is partly about finding a lock that fits the character of the door without drilling it up. Sometimes the existing lock body is fine and we are really talking about a rekey of an old house. Other times the hardware is worn through and replacing it is the right call. We will tell you which one we think it is.
Up in Glenoaks Canyon and Chevy Chase Canyon, you find mid-century hillside houses. The canyon sun is strong and Santa Ana winds are dry, and together they can dry out wood doors on hillside homes. A door that has shrunk or shifted can make a latch bind or a bolt miss the strike plate, and that sometimes gets blamed on the lock when the lock is not the real culprit. We check the door's alignment before deciding whether new hardware will actually fix the problem. Gate and garage locks on those hillside properties come up often too, and when the issue is a gate lock specifically, we handle that as its own job.
In Montrose and Sparr Heights, smaller cottages from the 1920s through the 1950s are common. Their front doors are usually modest, and a good deadbolt upgrade can make a real difference. Along Brand Boulevard and Honolulu Avenue in Montrose, storefront lock service is a regular scenario, and a worn or damaged cylinder on a shop door is a typical reason for a replacement call.
Closer to The Americana at Brand and Brand Boulevard, you find high-rise and podium condo buildings with controlled-access lobbies. Residents there sometimes need the lock on their own unit door replaced after a move or a damaged latch, while the lobby system stays in the building's hands. The flatland housing around the city center and Tropico mostly sees ordinary wear rather than weather damage, so replacement there is usually about age, heavy use, or a change in who lives in the home.
If you are anywhere in Glendale and you are not sure what your door needs, call and describe it. We can usually tell a lot from a short description.

We answer around the clock, every day of the year.
Call (213) 577-1366Which lock should you choose?
Once the old lock is out, you have a real choice, and it is worth making on purpose. A few directions people commonly take:
If you want sturdier protection on a front door, a better deadbolt is the single most useful change. We install them as a standalone job as well, covered on our deadbolt installation page. If you want to go further, our notes on high-security locks explain the extra protection against picking, drilling, and key copying.
If you like the idea of keypads or phone control, a smart lock can replace the traditional hardware. We will be honest about the tradeoffs: batteries, the need for a mechanical backup, and whether your door and frame suit the lock.
And if you just want something dependable that works, a solid conventional lock from a reputable maker is often the right answer. Not everything needs to be fancy.
Why call Wilshire Lock & Key for a replacement?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Glendale among them. We are one company with a real storefront at 10740 Wilshire Blvd in Westwood and our own mobile vans. When you call (213) 577-1366, you are not routed through a dispatch middleman who sends whoever is closest and hopes for the best.
David, the owner and lead technician, oversees the work. That matters on a replacement job, because the decisions that count most, like whether a door is sound enough for new hardware, are judgment calls made on site.
We also do not push replacement when something simpler will do. If a rekey or a small repair solves your problem, we will say so, even though it is a smaller job.
How do you know a locksmith is legitimate?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are thinking of hiring for that license number, and check it before they start work. A legitimate company will not mind the question.
A few other warning signs apply anywhere: a quote that changes once the technician arrives, pressure to drill out a lock that could have been picked or replaced cleanly, and a company that cannot tell you where it is based. Ask for the full scope of work before anything is removed from your door.
Frequently asked questions
How long does a door lock replacement take?
A single standard lock on a sound door is a short job. Several doors, a damaged frame, or a door that needs modification will take longer. The technician can tell you more once they see the door.
Can you replace a broken lock at night or on a holiday?
Yes. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year. A broken lock that leaves your home or business unsecured does not have to wait until morning.
Is it better to replace my front door lock or rekey it?
If the lock works well and you only want old keys to stop working, rekeying is usually the more economical route. If the lock is damaged, worn out, or a weak design, replacement is the better choice. We will tell you which one fits your situation when we look at it.
Will a new lock fit my old door?
Most standard residential locks fit standard bore holes without any trouble. Older doors, like some of the 1920s revival doors in Glendale, may have unusual holes or mortise hardware, and we check this before choosing a lock so we do not have to cut up the door unnecessarily.
Do I need permission to replace the lock in my Glendale apartment?
If you rent, check your lease and let your landlord or property manager know. Many buildings need management to keep a working key. If you own a condo, check your association's rules, since some limit the hardware on unit doors.
Can you replace locks on a business and key them all differently?
Yes. We can replace commercial cylinders and deadbolts and set up keying so each person's key opens only what they should access. Tell us how many doors and people are involved and we will suggest a plan.
What does lock replacement cost in Glendale?
It depends on the hardware, how many locks, the condition of the door and frame, key matching, the time of day, and travel. We do not post figures because they would be guesses. The technician will give you the full cost for your door before any work starts.
Can you upgrade my lock for better security, not just replace a broken one?
Yes. Many of our replacement calls are security upgrades on locks that still work. A better deadbolt, a reinforced strike plate, or a high-security cylinder can make a real difference at the door.
How do I check that a locksmith is legitimate?
Ask for their BSIS LCO license number, since California requires locksmith companies to hold one. Also ask where they are based and get the scope of work explained before they begin.
