Why change the locks on your Montebello home?
Most people who call us about a lock change are in one of a few situations. They just closed on a house and have no idea how many copies of the old keys are floating around. They moved into a rental and the previous tenant never handed back everything. A key went missing, or an ex-roommate or contractor still has one. Or the hardware has simply worn out and the door no longer feels right when it latches.
In every one of those cases the real question is the same: who can open this door right now, and do you want that list to be only the people you choose? A lock change answers that question. It is one of the more straightforward security fixes in a home, and it does not have to be a big expense or a big job.
The part that confuses people is the wording. Locksmiths say change, rekey, replace, and re-pin, and they do not all mean the same thing. Our job on this page, and on the phone, is to sort that out so you only pay for what your door actually needs.
Should you rekey or replace your locks?
This is the question behind most lock-change calls, and the honest answer is that it depends on the condition of the hardware and what you want from it. Here is how we think it through with customers.
- Rekey when the lock itself is in good shape. Rekeying changes the internal pins so the old keys stop working and a new key works instead. You keep the same lock body, finish, and handle. It is usually the more economical route and it is the right call for a lot of newly purchased homes. We cover the details on our lock rekey page.
- Replace when the hardware is worn, damaged, loose, or mismatched. If the latch drags, the key sticks, the finish is falling apart, or every door in the house uses a different brand, new hardware is often the cleaner fix. See lock replacement for how that works.
- Replace when you want a different kind of lock. If you want a keypad, a better deadbolt, or a smart lock, rekeying will not get you there. That is an upgrade, not a rekey.
- Rekey when you want every door on one key. If the house has a mix of keyways, we can often bring the exterior doors onto a single key, depending on the brands already installed.
- Replace when a lock cannot be rekeyed. Some very old or low-grade locks are not worth rekeying, or the parts are no longer available. We will tell you plainly when that is the case rather than push a rekey that will not hold up.

Call (213) 577-1366How does a lock change work when you call us?
We keep the process simple and we explain each choice before we start, so there are no surprises when you see the work.
- You call (213) 577-1366. Someone answers at any hour, any day. We ask what happened, how many doors are involved, what kind of locks you have now, and whether you want to keep them or upgrade.
- We help you narrow it to rekey or replace. Photos of the lock and the door can help, but we do not make final calls from a description alone when the hardware looks unusual.
- A mobile technician comes to your door from our van fleet, which works out of our Westwood base at 10740 Wilshire Blvd.
- On site, we look at every lock being changed: the deadbolt, the knob or lever, any secondary entries, the garage-to-house door, and a side gate if it has a lock. We confirm what can be rekeyed and what should be replaced.
- We explain the options and what affects the cost, and you decide before any work starts.
- We do the work, test every key in every lock, and check that each door latches and deadbolts smoothly, since a lock change is only useful if the door actually closes and locks easily.
- We hand over the new keys and tell you which ones work on which doors. If you want extra copies, we can handle that too through our key duplication service.
What affects the cost of changing locks in Montebello?
We do not quote a number on a web page, because the same phrase, change my locks, covers jobs that are very different in size. What we can do is tell you exactly what moves the cost up or down so you can judge any quote you receive, ours included.
The biggest factor is rekey versus replace. Rekeying existing hardware generally involves less material than installing new locks, so it is usually the lighter-cost option when your current locks are in good condition. Replacing means buying new hardware, and the grade and finish you choose make a large difference.
- Number of locks. Three doors take more time and parts than one.
- Type and condition of the existing hardware. Some locks rekey easily, while others are worn or discontinued and are better replaced.
- Grade of new hardware. Basic builder-grade sets, heavier-duty deadbolts, and high-security cylinders sit in very different places on the scale. If you are weighing that, our high security locks page explains what the extra grade buys you.
- Door and frame condition. A lock cannot do its job in a door that has warped or a strike plate that has pulled loose, so repairs to the door prep can add to the work.
- Timing and location. After-hours calls and farther travel can affect the total, which we explain before we start.
- Extras. Matching all doors to one key, adding duplicate keys, or installing a smart lock changes the scope.

Call (213) 577-1366Changing locks after buying a house or moving
If you have just bought a home, changing the locks should be one of the first things on your list, ahead of unpacking and ahead of most cosmetic projects. You do not know who the previous owner gave keys to. That could include former tenants, relatives, a house cleaner, a contractor, a real estate agent, or a neighbor who once watered the plants. None of those people are doing anything wrong by keeping a key, and yet you probably do not want them to have access to your new home.
For most new homeowners, rekeying every exterior lock to a single new key is the practical starting point. It shuts out every old key in one visit and gives you one key per person instead of a ring full of mystery keys. If something looks worn or poorly matched during the visit, we will tell you before we begin.
The same goes for a locksmith after moving into a rental. Landlords often rekey between tenants, but not always, and it is reasonable to ask. If you are the one renting out a property, our locksmith for landlords page covers turnover rekeys in more detail.
A few things worth checking at move-in, whether you hire us or not:
- Every exterior door, including the one from the garage into the house.
- Any side gate, shed, or detached garage that uses its own lock.
- The mailbox key, which is often forgotten.
- Garage door keypads or remotes, which are separate from the door locks.
- Any smart lock or keypad code that the previous owner may have set up.
What does a lock change look like around Montebello?
Montebello is a mix of housing types, and the type of home often decides what a lock change involves. In the older southern and central blocks, including South Montebello, you find 1920s Spanish-style bungalows. Many of those doors have had hardware swapped over the decades, and we often meet worn mid-century locksets that stick, rattle, or have lost their finish. In that kind of house, replacing worn locksets is often the better answer than rekeying, because a tired mechanism can fail again after a rekey.
Toward the hills, the postwar ranch tracts are larger, and many still carry original mid-century locksets. A common call here is a home rekey in the tracts north of Whittier Boulevard after a sale, where the hardware is sound enough to keep and the owner simply wants new keys. Around the Montebello Hills area, sloped lots and longer driveways mean the front door is further from the street than people expect, so securing every entry matters, including the garage-to-house door and any side gate.
Along the Garfield and Beverly corridors you find condos and apartments. If you are a tenant there, ask your property manager about lock changes before you alter anything. If you own the unit, we can change your entry lock and deadbolt, and if you are ever locked out we have a separate apartment lockout service.
We serve all of ZIP 90640, from North Montebello to the Town Center area near The Shops at Montebello and the Montebello Park area. Whichever part of town you are in, the question is the same: what is on your doors now, and does it deserve to stay?

Call (213) 577-1366Does Montebello's heat affect your door locks?
It can, mainly on older wood doors. Montebello sits at the edge of the western San Gabriel Valley, where summers run hotter than along the coast, and winters are mild. Heat makes older wood doors expand, which can pull a latch or deadbolt out of alignment with the strike plate. The result is a door that locks fine in the morning and binds by mid-afternoon.
That matters for a lock change because new hardware cannot fix a door that rubs. If your deadbolt only throws smoothly when you lift the door or push it, tell us. We can check the alignment, adjust the strike, and make sure the new lock works across the temperature range, not just on the day we install it. A new deadbolt on a misaligned door will feel as sticky as the old one did. If you are adding a deadbolt where none exists, see deadbolt installation.
Late spring marine-layer mornings are the other side of it: damp air does not harm modern lock cylinders much, but old, dry, unlubricated mechanisms can feel stiff. That is another sign an old lockset may be ready for retirement.
Why call Wilshire Lock & Key for a lock change?
There are plenty of locksmiths you can call. Here is what we can say about ourselves without exaggerating.
We have been in business since 1987. We run a real storefront at 10740 Wilshire Blvd in Westwood and send out our own mobile service vans, so the person who answers the phone works for the same company that arrives at your door. We do not hand your job to a dispatch middleman. We serve 140 cities across Los Angeles and Ventura counties, and Montebello is one of them.
David, the owner and lead technician, oversees the work. That matters on lock changes, where the judgment call, rekey or replace, is the whole job. We would rather tell you a rekey is enough than sell you hardware you do not need, and we would rather tell you a lock is worn out than rekey something that will fail again.
If you need someone outside business hours, our phone is answered 24 hours a day, every day of the year. If you want to know more about how our around-the-clock service works, see our 24-hour locksmith page.
What should you check before hiring any locksmith?
Lock changes are a trust job, since you are handing someone the keys to your home. In California, locksmith companies are required to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for it, us included, and be wary of anyone who dodges the question.
A few other habits help. Ask whether the person arriving works for the company you called. Ask for the work to be explained before it starts. Be cautious if a phone quote sounds unusually low and then changes at the door. And ask what happens to the old keys and old hardware, which should be yours to keep or dispose of.
If you would rather talk it through first, you can reach us on the contact page or just call (213) 577-1366.
Frequently asked questions
What is the difference between changing locks and rekeying them?
Changing locks often means replacing the hardware with new locks. Rekeying keeps the existing lock body and changes the internal pins so old keys stop working. Both stop the old keys from opening your door. Rekeying is usually the more economical route when the hardware is in good shape.
Should I change the locks right after buying a house in Montebello?
Yes, it is a smart first step. You cannot know who has copies of the old keys. For most homes, rekeying the exterior locks to one new key is enough, unless the hardware is worn or you want to upgrade.
Can you change locks 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, and our mobile vans serve Montebello from our Westwood base.
My Montebello house has original mid-century locks. Rekey or replace?
It depends on how they have held up. If the mechanism is smooth and the keys turn easily, rekeying can work. If it sticks, rattles, or the finish is failing, replacement is usually the better choice. We check on site and tell you which applies.
How many locks should I change when I move in?
At minimum, every exterior entry: front door, back door, the door from the garage into the house, and any side gate or detached building with a lock. Also consider the mailbox. We can match them all to one key where the hardware allows it.
Can you change my locks if I am renting?
Check your lease and ask your landlord or property manager first. If you are cleared to make the change, we can do it, and we can keep the original hardware so it can be reinstalled when you leave.
Can you switch me to a smart lock when you change my locks?
Yes. If you want keypad or app-based entry rather than a standard key, that is a replacement rather than a rekey. Our smart lock installation page explains what to consider.
How do I know what the lock change will cost?
It depends on how many locks, whether you rekey or replace, the grade of hardware, the condition of the door, and the time of day. We explain the options and what affects the total before any work begins, so you decide first.
Will the locksmith show a BSIS license?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith about it before they begin work. It is a reasonable question and a good habit.
