What does a lock rekey actually do?
Rekeying is the simplest way to take back control of who can open your doors. Inside a standard pin tumbler lock there is a set of small pins that line up only when the right key is inserted. When we rekey, we take the lock apart, change those pins so they match a new key cut, and put it back together. The lock body, the knob or deadbolt, and the finish on your door stay exactly as they are. The only thing that changes is which keys work.
The result is that every old key, including the one the previous owner kept, the one your ex-roommate never returned, and the one that fell out of your bag somewhere, becomes a piece of metal that no longer opens anything. You get fresh keys, and the hardware you already like stays on the door.
People search for this under many names: lock rekey, rekey service, lock rekeying, home lock rekey, house rekey, or just "rekey door locks." They all mean the same job. If you want the full picture of what we do around a home, our residential locksmith service in Hacienda Heights page covers the wider set of work. This page is about rekeying only.
When should you rekey your locks?
Most rekey calls fall into a handful of situations. If any of these sound like yours, rekeying is almost certainly the right move, and it is usually the more economical route compared with replacing hardware.
- Rekey locks after moving: you do not know who has copies of the keys to a place you just rented or leased, and neither does anyone else.
- Rekey locks after buying a house: the sellers, their agent, a lockbox, a past cleaner, a contractor, and a neighbor who watered the plants may all still hold a key.
- Rekey locks after a tenant moves out: tenant turnover is the most common reason a landlord or property manager calls us, and a rekey between tenants keeps one resident's key from opening the next resident's door.
- Rekey locks after losing keys: if you lost your keys and your address was on the ring, or you simply cannot say where they went, changing the locks closes the gap.
- After a breakup, a falling-out with a roommate, or an employee leaving on bad terms.
- After a break-in or attempted break-in where a key may have been taken, even if the door itself was not damaged.
- When you want one key to work every lock on the house instead of carrying a ring of mismatched keys.

Call (213) 577-1366How we rekey your locks, step by step
Every rekey follows the same basic order, whether it is a single front door or every lock in a house. We explain what we are doing as we go, because you should not have to guess what is happening to your own door.
- You call (213) 577-1366 and tell us what is going on: how many locks, what kind of doors, and why you want the change. A real person answers, at any hour.
- We look at what is on the doors. Most standard knobs, deadbolts, and handlesets can be rekeyed. Some very worn, damaged, or low-grade locks cannot be rekeyed reliably, and we tell you that before touching anything.
- We remove the lock cylinders one at a time, take them apart, and replace the internal pins to match a new key cut.
- We can set all the locks to one key, which is what most homeowners want, or leave certain doors on separate keys if that suits how you use the house.
- We reinstall each lock and test it with the new key from the outside and the inside, then test the old key to confirm it no longer turns.
- We check how the door and latch are operating while we are there. If a bolt is binding or a strike plate is misaligned, we tell you, because a lock that rekeys perfectly but drags on a misaligned door will still fail you eventually.
- You get the new keys and we go over what was done. If you want extra copies, we can cut them right then.
How much does lock rekeying cost in Hacienda Heights?
We do not quote numbers on a web page, because an honest rekey price depends on your actual doors, and anyone who gives you a flat figure without asking questions is either guessing or planning to adjust it later. What we can do is explain exactly what moves the cost, so you can judge any quote you receive from us or anyone else.
Rekeying is usually the lighter-cost option compared with replacing locks, because you are paying for labor and a small amount of parts rather than all-new hardware. That holds for most situations, but a few things change the total.
- The number of locks. Rekeying one deadbolt is a smaller job than rekeying every entry door, the garage side door, and a back gate.
- The brand and condition of the locks. Common residential brands rekey easily. Older, worn, or unusual locks can take more time or may not be good candidates at all.
- Whether keys are being changed to match each other. Setting every lock to a single key is routine, but combining mismatched brands takes extra work.
- How many new keys you want cut. Extra copies add a small amount to the job.
- The time of day. Calling for service in the middle of the night is different from booking a daytime appointment.
- Distance. Hacienda Heights is roughly 32 miles from our Westwood base, and travel is a real part of any mobile job.
- Add-ons. If a lock turns out to be damaged, or you decide to upgrade to a better deadbolt while we are there, that is separate work that we discuss before doing it.

Call (213) 577-1366Rekey, replace, or upgrade: which makes sense?
We will not talk you into new hardware when a rekey will do the job, and we will not rekey a lock that should be retired. The choice usually comes down to the condition of what is on the door and what you want it to do.
Rekey when the locks work smoothly, look fine, and your only concern is who holds the keys. That covers most situations after a move or a tenant change.
Replace when the lock is worn out, sticky, damaged by an attempted break-in, or an older style that you no longer trust. Our pages on changing locks and lock replacement cover that route in detail.
Upgrade when your main concern is stronger protection than a standard builder-grade lock offers. If that is you, look at high-security locks, which are designed to resist picking, drilling, and key copying.
One more point worth knowing: a rekey changes who can open the lock, but it does not make a weak lock stronger. A rekeyed builder-grade deadbolt is exactly as sturdy as it was before. We will tell you honestly if a door deserves more than a rekey.
Rekeying for tenants, landlords, and apartments
Tenant turnover is a steady source of rekey work. When a resident leaves, the keys they were given are no longer your business to leave in circulation. They may have made copies, handed one to a friend, or simply lost track of them. A rekey between tenants is routine, fast to schedule, and far less disruptive than replacing hardware on every unit.
For an apartment lock rekey or a townhome, the details matter: the entry door, any secondary deadbolt, the mailbox, and sometimes a patio slider or storage door. Landlords and property managers who handle several units often want consistent keying, which keeps the key ring manageable. If that is your situation, our page for landlords and property managers goes into how we handle ongoing turnover work.
If you are a renter rather than the owner, check your lease and talk to your landlord before changing any locks. In many cases the landlord arranges or approves the rekey, and you should keep them informed so everyone has the right key.
Commercial and business lock rekey
A commercial rekey follows the same principle as a home rekey, but the stakes around who holds keys are usually higher. When an employee leaves, a manager changes, or a lease transfers to a new tenant, rekeying the shop, back door, and storage room is the sensible response. It costs far less than replacing a full set of commercial hardware, and it works at once.
Businesses with many doors often need more than a simple rekey. If you want some staff to open only certain doors while a manager opens everything, a master key system is built for exactly that. It is a different job from a basic business lock rekey, and it is worth planning before you start changing cylinders one by one.
We also work on commercial doors that are damaged or aging. That is a separate service, and you will find it described on our commercial locksmith page rather than here.

Call (213) 577-1366Lock rekey in Hacienda Heights: homes, hillsides, and 91745
Hacienda Heights is mostly single-family tract homes built in the 1960s and 1970s, stretching from the flats near Valley Boulevard up into the Puente Hills. That age matters for rekeying. A house that has changed hands once or twice since then has had a lot of keys float around over the decades: original builders' keys, keys given to relatives, keys from earlier owners that were never collected. Many of these homes still carry the same locks they had when the family before the family before you lived there. If you have bought or are about to buy in ZIP code 91745, a full-house rekey is one of the first things worth putting on your list.
We see the most natural fit in the neighborhoods around the local high schools. Full-house rekeys after home sales are a regular kind of call in the Los Altos and Glen A. Wilson school areas, where families move in and out of long-held homes. On a typical job, we rekey the front door, the back door, the garage entry, and any side doors so one key works everywhere.
The flats in North Hacienda Heights near Valley Boulevard and the streets along the Hacienda Boulevard corridor are mostly flatland tract houses with a standard set of exterior doors, which makes a whole-house rekey straightforward. Higher up, the Puente Hills hillside neighborhoods tend to have more exterior doors, decks, and side access. It is worth walking the property before we start so no door gets missed.
Along the Colima Road corridor, you will find townhome and condo complexes where the unit door and a secondary lock are usually what need rekeying. Check with your HOA or management before changing exterior hardware, since some associations control which doors you can alter.
Canyon-edge properties near the Turnbull Canyon area sometimes have gates and long driveways. Rekeying the house is one job, and the gate lock is another. If a gate lock is stiff, jammed, or tired, look at our gate lock repair page. We can usually coordinate both in a single visit if you let us know when you call.
Climate plays a small part too. Hot, dry summers and strong sun on the hillside can warp sun-facing doors over time. When a door shifts, the bolt can bind in the strike plate, and that is often blamed on the lock itself. We check the alignment when we rekey, so you do not swap keys only to keep fighting a door that sticks. Coastal corrosion is not a concern here, which is one less thing to worry about with older hardware.
If you cannot get to us, ask about our mobile locksmith service. Our vans carry what we need to rekey on site, so you do not have to bring your locks anywhere.

Call (213) 577-1366Why call Wilshire Lock & Key for a rekey
We have been in business since 1987, and that is a long time to see how locks age and how people end up needing them changed. We are a storefront at 10740 Wilshire Blvd in Westwood with mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, including Hacienda Heights.
When you call, you reach us, not a call center that passes your job to whoever happens to be free. We do not operate through dispatch middlemen, so the company you talk to is the company that shows up. David, the owner and lead technician, oversees the work, and that means someone who knows the trade is accountable for how it is done.
The phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round. A lost key or a locked-out new homeowner does not wait for business hours, and neither do we.
One more honest point. California requires locksmith companies to hold a BSIS LCO license, which is issued through the Bureau of Security and Investigative Services. You should ask any locksmith for it before you let them work on your doors, and that includes us. It is a fair question and a reasonable way to avoid trouble.
What to have ready when you call
A few details speed things up and help us give you an accurate idea of the work.
- How many doors or locks need changing, and which ones: front, back, garage entry, side doors, gates, mailbox.
- Whether you want every lock on one key or certain doors kept separate.
- Whether the property is a house, apartment, townhome, or business.
- Anything unusual: a damaged lock, a door that sticks, or a smart lock already on one of the doors.
- How many new keys you want when we finish.
- Whether anyone will be on site to let us in, and whether you are the owner, tenant, or manager.
Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps your existing locks and changes the inside so a new key works and the old ones do not. Changing locks means taking the hardware off and installing new locks. Rekeying is usually the lighter-cost route when your locks are in good shape. Changing makes more sense when they are worn, damaged, or you want better security.
Should I rekey locks after buying a house in Hacienda Heights?
Yes, it is one of the most sensible first steps. You cannot know how many copies of the old keys exist, and many homes in the area have been through multiple owners since the 1960s and 1970s. Rekeying the exterior doors means only the keys you hold will work.
Can you rekey all the locks in my house to one key?
In most cases, yes. We can set the front door, back door, garage entry, and side doors to a single key, as long as the locks are in rekeyable condition. If your locks are from different brands, we explain what is possible before we begin.
How long does a rekey take?
It depends on the number of locks and their condition. A single door is a quick job, and a whole house takes longer. We do not promise set times on a web page, but when you call (213) 577-1366 we can describe what to expect for your situation.
Do I need to be home during the rekey?
Someone should be there to give us access to the doors, and ideally to confirm the new keys work before we leave. If you are a landlord or manager, tell us when you call so we can plan around a vacant unit or an agreed access arrangement.
Will my old keys still work after a rekey?
No. That is the point of the work. After we rekey, we test with the new key and then try the old one to confirm it no longer turns. Anyone holding an old copy will not be able to open that lock.
Can you rekey a business or restaurant in a Colima Road shopping plaza?
Yes. We rekey storefront doors, back doors, and storage rooms. If you want different staff to open different doors, ask about a master key system. If any hardware is damaged, we can talk about repair or replacement separately.
Can any lock be rekeyed?
Most standard residential and commercial pin tumbler locks can. Some are too worn, damaged, or poorly made to rekey reliably, and a few specialty locks have restrictions. We look at your locks first and tell you honestly if replacement would serve you better.
I lost my keys. Do I need to rekey or just replace my locks?
If your locks work well, rekeying is usually enough, because it makes the lost keys useless. If the door was damaged or the lock is already failing, replacement may be the better answer. If you are also locked out, call us and we will start with getting you inside.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for it before any work begins, and check that the company has a real address and a person you can talk to. A locksmith who avoids those questions is not one to hire.
