What does a lock rekey actually do?
Rekeying changes the inside of a lock so a different key operates it. The lock stays on your door. Inside the cylinder is a set of small pins that line up only when the right key is inserted. We take the cylinder apart, replace the pins with a new combination, and cut keys to match. The old key may still slide into the keyway, but it no longer turns.
That is the whole point. If you lost keys, moved into a place that other people have had keys to, or simply do not know how many copies are floating around, a rekey cuts off every one of them in a single visit. The door, the handle, the deadbolt and the finish all stay as they are, which is why people often choose it when the hardware is still in good shape.
You may have searched for this as rekey locks, lock rekeying, house rekey, home lock rekey or rekey door locks. It is all the same job. What changes from one door to the next is the type of hardware, the number of locks, and whether you want them keyed alike so a single key opens the front door and the back deadbolt.
When does rekeying make sense?
Most rekey calls start with a situation, not a lock problem. These are the ones we hear most often:
- Rekey locks after moving: you cannot know who the previous occupant handed keys to, whether relatives, cleaners, neighbors or contractors.
- Rekey locks after buying a house: the seller, the previous owner's friends and anyone who ever house-sat may still hold a working key. Many buyers rekey before the first night in the home.
- Rekey locks after a tenant moves out: a key that was never returned, or that was copied along the way, is still a working key. This is the heart of tenant turnover rekey work.
- Rekey locks after losing keys: if the keys vanished with an address attached, or you simply cannot say where they went, changing the lock is the safe answer.
- Rekey all house locks to one key: carrying a ring of separate keys for the front door, back door and side entrance gets old fast, and keyed-alike rekeying fixes that.
- After an employee, manager or contractor leaves: a business lock rekey shuts off that person's access without replacing every door in the building.
How does our rekey service work, step by step?
Here is how a typical visit goes, whether it is a house, an apartment or a shop.
- You call (213) 577-1366 and tell us what you have: how many locks, what kind (knob, deadbolt, lever, padlock), and why you want them changed. The line is answered around the clock, any day of the year.
- We talk through whether rekeying fits. Some locks cannot be rekeyed cleanly, and we tell you that up front instead of finding out on your doorstep.
- A technician comes to you in one of our mobile vans, carrying pins, tools and key blanks. We confirm that the person asking for the work is the resident, owner or property manager.
- We remove each cylinder, replace the pin stack and cut new keys. If you want several locks on one key, we match them so they all work together.
- We test every lock with the new key and with the old key. The new key must turn smoothly, and the old key must fail.
- You get your new keys, and we explain how to order additional copies later so you stay in control of who holds them.

Call (213) 577-1366Should you rekey or replace the lock?
Rekeying is usually the more economical route when the hardware is sound. But it is not always the right call, and we would rather say so than sell you a rekey that does not solve your actual problem.
A rekey also will not fix a door that does not latch properly or a strike plate that is loose in a soft frame. New keys on a weak door are still a weak door. If we notice something like that while we are there, we point it out and leave the decision to you.
- Rekey when the locks turn smoothly, look acceptable, and all you need is to change who holds keys.
- Replace when a lock is worn, sticking, loose in the door, damaged by a break-in attempt, or a style you simply do not want anymore. Our lock replacement service covers that.
- Replace or upgrade when you want better security, such as a stronger deadbolt or a keypad, rather than the same lock with different pins.
- If you want new hardware across the whole house at once, changing the locks outright may be the cleaner job.
- Some very worn, damaged or incomplete cylinders cannot be rekeyed reliably. In that case replacement is the honest answer.
What affects the cost of a lock rekey?
We do not publish flat numbers on a web page, because two rekey jobs that sound alike can differ a lot once you look at the doors. What moves the cost is straightforward:
- The number of cylinders. One deadbolt is a smaller job than every exterior door, a side gate and a garage entry.
- The lock type and keyway. Standard residential cylinders are the simpler case. Restricted or high-security keyways can need special key blanks and more careful work.
- Whether you want locks keyed alike. Matching several different locks to one key can take more effort, and mixed brands sometimes cannot be combined.
- The condition of the hardware. A cylinder that is dirty, worn or partly broken can take longer, or may be better replaced.
- How many keys you want cut. More keys means more cutting time and more blanks.
- Time of day and travel. Night, weekend and holiday calls cost more to staff than a scheduled daytime visit, and Santa Fe Springs is about 25 miles from our Westwood storefront.
- Commercial complexity. Facilities with master-key arrangements, interchangeable cores or many doors take more planning than a single-family home.
How does tenant turnover rekey work for landlords and property managers?
Rekeying between tenants is routine for anyone who rents out a property, and it is the lighter-cost way to reset access compared with replacing every lock in a unit. Many landlords simply add it to the turnover checklist: tenant leaves, we rekey, new tenant gets keys nobody else holds.
For an apartment lock rekey, we usually handle the entry door and any secondary deadbolt, and we can do the mailbox or shared-area locks if you ask. If you manage several units, tell us at the start. Consistent keyways and clear labeling keep the keys you hold as manager organized, and that saves you headaches the next time a unit turns over.
We do not make legal calls about notice or lease terms, so check your lease and local rules on your side. What we do is make the lock side of the turnover quick, tidy and documented. Landlords with more than a couple of doors should also look at our locksmith services for landlords, which cover the wider picture.

Call (213) 577-1366What about commercial rekey and business lock rekey?
Santa Fe Springs is predominantly an industrial city, and that shapes how we think about rekeying here. A commercial rekey is not just a bigger version of a house rekey. Commercial doors often use different cylinder styles, such as mortise cylinders, rim cylinders or interchangeable cores, and they are tied to who is allowed where and when.
Typical reasons for a business lock rekey include a facility changing hands, a manager or supervisor leaving, a lost key on a ring that opens several doors, or tightening access to an office, parts room or tool crib. A commercial lock rekey lets you shut off old keys on the exterior doors and sensitive interior rooms without replacing the hardware.
If you need keys arranged in tiers, with one key for a single door, another for a department and a top key for management, that is a master-key system, and we cover it separately on our master-key system page. For broader hardware, exit devices or door work beyond the cylinders, see our commercial locksmith services. A rekey is often the first, simplest step before deciding whether you need either.
Where do we rekey in Santa Fe Springs?
Warehouses, machine shops and distribution facilities take up most of the land in Santa Fe Springs, so commercial hardware far outnumbers residential work here. The smaller residential side is a core of 1950s single-family tract homes clustered around Telegraph Road and the Town Center area, mostly single-story ranches, with some newer townhomes near the civic core.
In the Town Center and Telegraph Road residential core, and in the Little Lake Park neighborhood around Lakeland Road and Pioneer Boulevard, residential rekeys are the common job: a new owner who wants a clean slate on the keys, or a landlord resetting a rental between tenants. Homes of that age can have hardware replaced piece by piece over the decades, so it is not unusual to find a mix of key types on one house. Rekeying everything to a single key is a tidy way to fix that, as long as the locks are compatible.
Along the Santa Fe Springs Road industrial corridor, the work is business lock rekey: a supervisor leaves, a tenant moves out of a unit, or a key goes missing from a shared ring. Summer heat combined with heavy truck-corridor dust is harder on commercial door closers and exterior padlocks than on residential hardware, so on dock, yard and side doors we look at the condition of the hardware before deciding that a rekey alone is enough.
Vendors at the Santa Fe Springs Swap Meet rely on padlocks and storage locks. Many padlocks can be rekeyed or keyed alike so one key opens the whole set, though some cannot, and we tell you which is which before we start.
Whether your address is in ZIP code 90670 along Lakeland Road, in the Sorensen Avenue corridor near unincorporated West Whittier-Los Nietos, or toward the northwest edge near Los Nietos, we come to you in a mobile locksmith van with the tools to rekey on the spot.

Call (213) 577-1366How do you keep control of keys after a rekey?
A rekey is only as good as the key control that follows it. If you hand out copies freely, you have rebuilt the problem you just fixed. A few habits help:
- Decide who really needs a key before you order copies, and write the names down.
- Order extra copies through us or another trusted source rather than a self-serve kiosk. For that, see our key duplication service.
- For rentals and shared properties, keep a simple log of which keys went to whom.
- If managing physical keys keeps causing trouble, consider a keypad or app-based lock. Our smart lock installation page explains when that is a better fit than a rekey.
Why call Wilshire Lock & Key for a rekey?
We have been in business since 1987, serving 140 cities across Los Angeles and Ventura counties. You get a real storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans. When you call (213) 577-1366, you reach us, not a call center that sells your job to whoever is nearest. We are one company with no dispatch middlemen between you and the technician.
David, the owner and lead technician, oversees the work. That matters on rekey jobs, where small details such as a mismatched pin stack or a missed cylinder are the difference between a lock that works and one that causes a callback.
One more piece of advice that applies to any locksmith, including us. California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask any locksmith for it before they start. It is a fair question, and a reputable company will answer it plainly.
If you are not sure whether you need a rekey, a replacement or something else, call and describe what is going on. We will tell you what we would do if it were our own door.
Frequently asked questions
Can I get my locks rekeyed in Santa Fe Springs at night or on a weekend?
Yes. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year. Our mobile vans travel to Santa Fe Springs, which is about 25 miles from our Westwood storefront. Call, describe the job, and we will tell you what to expect for timing and cost.
Will my old keys still work after a rekey?
No. After a rekey the old key will not turn the lock. We test each lock with both the new key and the old one before we leave, so you can see for yourself that the old key fails.
Should I rekey the locks after buying a house?
It is not required, but most people do it. You cannot know how many copies of the old keys exist or who holds them. Rekeying gives you a fresh set without paying for new hardware, and it is often the more economical choice when the existing locks are still in good shape.
Can you rekey all my house locks to the same key?
Usually, yes. Locks of compatible types can be keyed alike so one key opens the front door, back door and deadbolts. Occasionally a lock from a different brand or a worn cylinder cannot be matched, and replacing that one lock is the cleaner fix. We tell you before we begin.
Can you rekey a lock if I do not have any key for it?
Usually, yes. Because we remove and rebuild the cylinder, we do not always need a working key. We do ask you to show that you are the resident, owner or manager before we change access to a property.
Is rekeying or changing the locks better for a rental unit?
For tenant turnover, rekeying is usually the lighter-cost route when the locks are in decent condition. Replacement makes more sense if the hardware is worn, damaged, or you want an upgrade. We can look at the doors and tell you which one fits the unit.
Do you rekey commercial doors and padlocks in Santa Fe Springs?
Yes. We handle commercial rekeys on shops, offices, warehouses and yards, and we can rekey or key alike many padlocks. Some padlocks and specialty cylinders cannot be rekeyed, and we say so when we see them. For tiered key arrangements, we handle master-key systems as a separate service.
Do I need to be home while you rekey the locks?
Someone authorized needs to be there, or you need to arrange access with us ahead of time. For rentals, a property manager can be the contact. We confirm authority before changing a lock, then test everything with whoever is on site.
How can I tell a locksmith is legitimate before they start work?
Ask for their BSIS LCO license. California requires locksmith companies to hold one, and a reputable company will give you the number without hesitation. Also ask who is coming, what the work will cost before it starts, and whether the company has a real storefront.
