When does a lock need replacing instead of fixing?
Most locks do not fail all at once. They get stiff, the key needs a wiggle, the latch drags on the strike plate, or the deadbolt only throws when you lean on the door. Plenty of those problems can be handled with cleaning, adjustment, or a small part. A real lock replacement makes sense when the problem is deeper than that, and a good locksmith will tell you honestly which side of the line you are on.
Replacing the lock is usually the right call when the cylinder is worn enough that keys stick or break, when the lock has been forced or pried and the body is bent, when the finish has corroded so the mechanism no longer moves cleanly, or when the hardware is so old that parts are hard to find. It also makes sense when the lock simply does not match what the door protects anymore, such as a basic keyed knob on a front entry that deserves a proper deadbolt.
- The key turns only with force, or it has already snapped once.
- The lock was damaged in a break-in attempt, even if it still seems to work.
- The bolt does not fully extend, or the handle spins without engaging the latch.
- You cannot account for every key that exists to the lock.
- The hardware is loose, rusted, or rubbing against a swollen or shifted door.
- You are upgrading for security, not because anything broke.
How does Wilshire Lock & Key replace a lock in San Gabriel?
The process is simple, and we explain each decision as we go so you are never guessing why we recommend something.
- Call (213) 577-1366. A person answers around the clock, every day of the year. Tell us what the lock is doing, which door it is on, and whether it is a house, apartment, or business.
- We ask a few practical questions: the type of lock, how old the door is, whether you have working keys, and whether the door is closing and latching properly. This helps us bring the right hardware in the van.
- A mobile technician comes to the property. We look at the lock, the door, the strike plate, and the frame before touching anything, because a new lock on a misaligned door will not last.
- We explain the options plainly: replace like for like, step up the hardware, or fix a smaller problem if that is all it takes. You choose.
- We remove the old lock, fit the new one, and check the bolt, latch, and strike plate alignment so everything throws smoothly without force.
- You test it with every key, from inside and out, before we call the job done. We set up the keys so you know exactly how many exist and who has them.

Call (213) 577-1366Should you replace the lock or just rekey it?
This is the question we get most, and the honest answer is that it depends on the condition of the hardware, not on which option sounds more thorough. If your lock is in good shape and your only worry is who has keys, such as after a move, a breakup, a roommate leaving, or a lost key, rekeying the existing lock changes the key without changing the hardware. It is usually the more economical route when the lock itself is sound.
Replacement is the better path when the hardware is the problem. A worn cylinder that has been rekeyed three times will still be a worn cylinder. A lock with a bent bolt or a cracked body will not get safer by being rekeyed. And if the existing lock is a low-grade builder model on a door that faces the street, you may want to move up to something with a sturdier bolt and a more pick-resistant cylinder.
If the lock is mostly fine and only one part has gone wrong, lock repair may be all you need. We will tell you that on site. Selling a full replacement when a repair would do is not how a business lasts since 1987.
What does replacement look like for a front door, an apartment, or a business?
The word replacement covers quite different jobs depending on the building. Here is how we think about each one.
- Front door lock replacement: this usually means a new deadbolt, a new handle set, or both. We check that the door bore and the latch edge are in good shape, that the strike plate is anchored with screws long enough to reach the framing, and that the door is not rubbing. If you want to add a deadbolt where there is none, see deadbolt installation.
- House and residential lock replacement: for a whole house, the practical advantage is a matched set, so one key works the front, back, and side doors. We can replace the lot in a single visit and key them alike.
- Apartment lock replacement: tenants generally need the landlord's approval before changing hardware, and landlords often have rules about keeping access for maintenance. If you manage rentals, our locksmith services for landlords cover turnover between tenants without the guesswork.
- Business lock replacement: shops, restaurants, and offices need hardware that takes daily abuse and may need keying that matches a larger system. Storefront doors and glass-door hardware are their own category, and our storefront lock repair page covers the cases where repair is enough.
- Security lock upgrade and business security upgrade: if you are replacing a working lock because you want more protection, we talk through the real weak points. Often the lock is not the weakest part. A short strike plate screw or a thin door frame can matter more than the cylinder.

Call (213) 577-1366What affects the cost of lock replacement?
We do not publish numbers on a web page because the real figure depends on the job in front of us. What we can do is tell you exactly what moves the cost, so nothing about it is a surprise when you call (213) 577-1366.
The biggest factor is the hardware itself. A standard residential knob or deadbolt is a different product from a high-security cylinder with restricted keys, and both differ from a commercial-grade lever or mortise lock. Hardware is graded by how much abuse it is built to survive, and the higher the grade, the more it generally costs. Finish and brand matter too, particularly if you want the new lock to match existing handles.
Beyond the hardware, these things shape the total:
- The number of locks being replaced and whether they should be keyed alike.
- Whether the door and frame are in good shape, or need adjustment, a new strike plate, or reinforcement for the new lock to work properly.
- The type of door: solid wood, hollow-core, metal, or glass, since each has its own installation requirements.
- Whether the lock is a conventional keyed model, or a smart lock that needs setup and testing. See smart lock installation if that is what you are leaning toward.
- The time of day and urgency. A planned visit during the day is a different situation from a late-night call after a break-in.
- Travel to the property. Our storefront is in Westwood and San Gabriel is about 22 miles from our base, and our vans are out on the road across our service area.
Lock replacement across San Gabriel: what we see around town
San Gabriel is not one kind of housing, and that changes what a lock replacement involves. In North San Gabriel near the San Marino border, there are larger prewar and ranch homes on generous lots, and in the Mission District some of the city's oldest houses still stand. Older homes frequently carry original mid-century locksets. Those can be worn out after decades of use, and replacement hardware does not always fit the old bore holes. We measure and fit carefully, sometimes with a different plate, so the door does not end up with extra holes and a sloppy look.
The climate adds a small wrinkle. San Gabriel Valley summers are hot and dry, and heat can swell wood doors in older housing. It is a routine issue, not a severe one, but a swollen door that drags against its frame will wear out a new lock quickly. We check the fit of the door before and after, because a lock that has to fight the door will fail early.
Along Valley Boulevard and Del Mar Avenue, the stock is denser: postwar apartments, condo complexes, and newer townhome infill. In ZIP 91776 and ZIP 91775 alike, that often means several units with similar hardware and a property manager who wants consistent, reliable replacements. Condo complexes off Las Tunas Drive also have shared gates and mailboxes, and a worn mailbox lock is its own small job; see mailbox lock replacement.
On the business side, restaurants and storefronts along the Valley Boulevard Golden Mile near San Gabriel Square run their doors hard, with staff opening and closing at all hours, and their locks wear faster than a house's. We also see lock work for medical offices near San Gabriel Valley Medical Center, where tidy key control and dependable hardware matter. Whatever the address, we bring the hardware by van to you.

What should you ask any locksmith before they start?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Whoever you hire for a lock replacement, ask for that license number and check it. It is a reasonable question, and a reputable company will not mind answering it.
A few other questions are worth asking up front: what hardware will go on the door and what grade it is, whether the price is confirmed before work starts, how many keys you will receive, and whether the company is a local business with a real address. Be cautious of anyone who quotes an unusually low number on the phone and then changes it at the door. Explaining what drives the cost before starting is the honest way to do it.
Frequently asked questions
How quickly can you replace a lock in San Gabriel?
Our line at (213) 577-1366 is answered 24 hours a day, every day, and a mobile van comes to you. We do not promise a set arrival time because traffic and workload change, but we tell you what to expect on the call, and urgent situations like a broken lock after a break-in are treated as such.
Do I need to replace the whole lock, or can you just swap the cylinder?
Sometimes the cylinder alone can be swapped if the rest of the lock is in good shape and the brand allows it. If the body, latch, or bolt is damaged or worn, a full replacement is the sounder choice. We look at it on site and tell you which makes sense.
Will a new lock fit my older house in the Mission District?
Usually yes, though older doors with original mid-century hardware can have odd bore sizes or worn mortises. We measure first and choose hardware or a trim plate that fits cleanly, so the door is not left with extra holes or a loose fit.
Can you replace the locks in my apartment?
Yes, but check your lease first. Most landlords want to approve lock changes or keep access for maintenance. If you manage the building, we can replace and key units consistently. If you are locked out of an apartment instead, see our apartment lockout service.
Is a lock replacement or rekey the more economical option?
If your current lock is in good condition and you only want new keys, rekeying is usually the more economical route. If the lock is worn, damaged, or low-grade, replacing it is the better use of money. We will say which applies to your door.
Can you replace a lock on a business, like a restaurant or medical office?
Yes. We handle business lock replacement and business security upgrades, including storefront doors and offices. Commercial doors usually need heavier hardware and sometimes keying that fits a larger system, so we ask about how the door is used before recommending anything. See our commercial locksmith page for the wider scope.
Do I need a new lock after a break-in attempt?
Often yes, even if the lock still seems to work. Forcing a door can bend the bolt, crack the body, or loosen the strike plate and frame. We inspect everything and replace what is compromised, and we can strengthen the frame and strike plate as part of the visit.
How do I know a locksmith is legitimate?
Ask for their BSIS LCO license number, which California requires of locksmith companies, and confirm they have a real local address and will explain the cost before starting. Our storefront is at 10740 Wilshire Blvd, Los Angeles, CA 90024, and you can reach us any time at (213) 577-1366.
