How do you know a lock needs replacing and not just fixing?
Most people call us about lock replacement after something has gone wrong: a key snaps off, a deadbolt stops throwing all the way, or a handle spins without catching the latch. Others call because nothing has failed yet, but the hardware is old, the finish is flaking off, or they have no idea how many copies of the key are floating around. Both are fair reasons. A lock is a mechanical part, and mechanical parts wear out.
The real question is whether the lock can be put right or whether it should come out. A worn cylinder that sticks can sometimes be serviced. A bolt that has been forced, a body bent during a break-in attempt, or a lockset whose internal parts have loosened is a different story. Putting effort into a part that is already failing usually costs more over time than replacing it once and being done.
These are the signs that tell us a replacement is the sensible path:
- The key goes in rough, needs jiggling, or turns only part way.
- The deadbolt has to be lifted, pushed, or leaned on to line up with the strike plate.
- The lockset wobbles on the door or the handle droops.
- There is visible damage: pry marks, a cracked trim plate, a bent latch, or a cylinder that has been drilled or hammered.
- Corrosion, or a finish worn through to bare metal.
- The hardware is simply outdated and no longer something you would trust on an entry door.
- You have lost keys, or you cannot account for who holds copies, and fresh hardware is cleaner than a patch.
How does a lock replacement visit work, step by step?
We keep the process plain so you always know what is happening to your door. If the issue turns out to be small, we will say so and point you toward lock repair rather than sell you something you do not need.
- You call (213) 577-1366. Someone answers at any hour, every day of the year. Tell us what the lock is doing, which door it is on, and whether the door is still secure.
- A mobile van comes to your address. We are based at our Westwood storefront, and Rowland Heights is a drive from there, so when you call we will tell you plainly when we can arrive.
- We look at the door before touching the lock. We check the door thickness, the bore holes, the backset, the strike plate, and the condition of the frame, because a new lock is only as solid as the wood it bolts into.
- We walk you through the options and explain what drives the total before we remove anything. You decide whether to replace, rekey, or upgrade.
- We remove the old hardware and fit the new lock. We line up the latch and bolt with the strike, tighten the mounting properly, and test the lock with the door open and closed.
- We hand over the keys, show you how everything operates, and take the old parts away unless you want them kept.

Call (213) 577-1366Replace, rekey, or repair: which is the lighter-cost option?
Replacement is not always the answer, and we would rather tell you that than install hardware you did not need. The usually more economical route depends on what is actually wrong.
If the lock body is sound and you only want old keys to stop working, lock rekeying changes the internal pins so the existing hardware takes a new key. That is common after a move, a breakup, a roommate leaving, or a lost set of keys. If the lock is sticky but undamaged, repair may be enough.
Replacement makes more sense when the hardware itself is the problem. That means a body that is worn out, parts that are damaged or forced, a finish that has corroded, or a lock grade that is too light for the door it protects. It also makes sense when you want something better than what is there, such as moving from a basic builder-grade knob to a sturdier deadbolt and strike setup.
One honest caution: a new lock on a weak frame does not buy you much. If the door jamb is split or the strike plate is held in with short screws, we will point that out, because that is often where a break-in actually succeeds.
What affects the cost of lock replacement?
We do not publish numbers on a web page because the job in front of us decides the price, and a guess from a distance helps nobody. What we can do is tell you exactly what moves the total, so a quote from us or anyone else makes sense to you.
- The lock itself. Basic keyed entry hardware, a higher-security cylinder, a keypad lock, and a smart lock sit in very different places, and brand and grade matter.
- How many locks. Replacing one front door lock is a different job than replacing every exterior door on a house or every unit door in a building.
- The state of the door. Misaligned bores, a damaged jamb, or a strike plate that needs reinforcing add work.
- Keying choices. Having several locks work from one key, or restricting key copies, takes extra setup.
- Time of day. Calls in the middle of the night or on a holiday involve different logistics than a scheduled daytime visit.
- Travel to your location. Rowland Heights is a distance from our base, and we factor that in honestly.
- Whether it is an emergency. A forced or broken lock that leaves a door unsecured needs to be made safe first.

Call (213) 577-1366What kinds of residential lock replacement do we do?
For homes and apartments, most of our replacement work falls into a few familiar categories.
Front door lock replacement is the most common. That covers the deadbolt, the handle or knob set, or both together. We can match finishes so the door looks like one piece of hardware rather than a mix of leftovers. House lock replacement often goes beyond the front door: the back door, the side door, and the garage-entry door all count as ways in, and they are frequently the weakest.
Apartment lock replacement comes up when a tenant moves in, a tenant is removed, or a key goes missing. If you rent, check with your landlord or property manager before changing hardware, because many leases require permission and a copy of the key. Property owners managing several units can read about our work with landlords to see how we handle repeat jobs.
A security lock upgrade is a different reason to replace. You may want a better deadbolt on a door that only has a spring latch, or a deadbolt installed where there was none. You may prefer smart lock hardware that works with a code or phone. Or you may want pick-resistant, drill-resistant high-security locks for a door that matters most. We will tell you plainly when a premium lock is worth it and when a solid standard one does the job.
Do you handle commercial and business lock replacement?
Yes. Commercial lock replacement has different demands than a house. Doors get used all day, hardware takes a beating, and the lock often has to meet a fire or exit requirement as well as keep people out. A cheap residential lock on a busy shop door tends to fail early.
Business lock replacement usually starts with a simple question: who has keys, and do you know? Staff turnover, a former partner, or a lost key ring is reason enough to change the cylinders. We can replace a single failing storefront lock, or we can look at the whole building and suggest a business security upgrade that makes sense for how you operate, from sturdier hardware on the back door to a keying plan that controls who can open what.
If your problem is a storefront door that is sticking, misaligned, or not latching, storefront lock repair may be the better fit, and we will tell you which when we see it.
What should Rowland Heights homes and businesses know about lock replacement?
Rowland Heights sits in ZIP code 91748, in the Puente Hills area of eastern Los Angeles County, and the housing varies a lot from one pocket to the next. That affects what a lock replacement actually looks like.
Much of the area is tract homes from the 1960s through the 1980s. Houses of that age can have hardware that has been replaced over the years, or that has simply aged in place. If you bought one recently and are not sure who has keys, replacing the exterior locks or at least rekeying them is a sensible first move.
Along the Colima Road and Fullerton Road corridors, townhome and condo complexes are common. Lock replacement there tends to be about entry doors and sometimes patio or garage-access doors. Because complexes often have rules about exterior door appearance, check with your association before changing a finish. We can match to what is already on the building.
In the hillside neighborhoods south of Pathfinder Road, and in the gated communities there, side gates and garage-entry doors often serve as primary access points on view-lot homes. Those doors and gates deserve the same attention as the front door. For a gate latch or gate lock that has given out, our gate lock repair service covers the hardware side.
Climate matters too. Summers in the eastern San Gabriel Valley are warm to hot and dry, and the sun-exposed hillside lots around Pathfinder Park and the Nogales Street corridor are breezy and open. South-facing doors and gate hardware weather the hardest. Finishes fade, springs tire, and cylinders collect grit. If your front door faces south, ask us about durable finishes when choosing replacement hardware.
On the business side, restaurants and storefronts in the shopping plazas along Colima Road and Fullerton Road go through a lot of door cycles every day. If a lock on a plaza storefront has been repaired more than once, it is probably time to replace it instead of nursing it along.

Call (213) 577-1366Why call Wilshire Lock & Key for a lock replacement?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. That is a lot of doors, and it means we have seen most of the ways locks fail. David is the owner and lead technician, and he oversees how the work is done.
We are one company. There is a storefront at 10740 Wilshire Blvd in Westwood and a fleet of mobile service vans. When you call (213) 577-1366, you are not routed through a dispatch middleman who hands your job to whoever is closest. The phone is answered 24 hours a day, 7 days a week, all year, so a broken lock on a holiday night gets the same attention as a Tuesday morning appointment.
We also tell you the truth about the job. If a repair will do, we say repair. If a rekey will solve it, we say rekey. If a door frame is the real problem, we say that too.
One more thing worth knowing: California requires locksmith companies to hold a Bureau of Security and Investigative Services (BSIS) locksmith company license, known as an LCO license. Ask any locksmith for it before they start work, and expect a clear answer. If your lock failed at an inconvenient hour and the door will not secure, our emergency locksmith page explains how we handle those calls.
Frequently asked questions
Can you replace a broken lock at night or on a weekend in Rowland Heights?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, including holidays. If a lock is broken and your door will not secure, call and tell us what happened. We will tell you when a van can reach you and what we will do to make the door safe.
How much does lock replacement cost?
It depends on the lock you choose, how many doors are involved, the condition of the door and frame, any keying requirements, the time of day, and travel to your address. We explain these before starting so the total makes sense. A lighter-cost option such as rekeying may be available if your lock is still in good shape.
Should I replace my lock or just 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 worn, damaged, corroded, or too light for the door, replacement is the better choice. We will look at the lock and tell you which makes sense.
Will a new lock fit my existing door?
Most standard entry doors take standard hardware, but we check the door thickness, bore holes, and backset before choosing a lock. If something is unusual, such as an older door, a custom bore, or a gate, we find the right match or adjust the preparation. We do not force hardware onto a door it does not fit.
I rent an apartment. Can I have the lock replaced?
Check your lease and talk to your landlord or property manager first. Many require permission and a copy of the key. Once that is sorted out, we can handle apartment lock replacement. We may ask you to confirm that you are authorized to have the work done at the property.
Can all my exterior doors use the same key?
Yes. We can set up several locks to work with one key so you are not carrying a ring of different keys. Tell us which doors you want included, such as the front, back, side, and garage-entry doors, and we will plan the keying when we choose the hardware.
Do you replace locks on businesses and storefronts?
Yes. We do commercial lock replacement and business security upgrades for shops, restaurants, and offices. We can swap one worn cylinder or plan a bigger change that controls who can open which door. If it is a simpler storefront door issue, we will tell you whether repair is enough.
What about the old lock after you replace it?
We take it with us unless you want to keep it. If you suspect the lock was tampered with or forced, tell us and we will point out the damage so you know what happened and whether the door or frame needs attention as well.
