What does a lock rekey actually do?
A lock rekey changes the inside of a lock so it works with a new key and your old keys stop working. The lock itself stays on the door: same deadbolt, same handle set, same finish. We take the cylinder apart, swap the small internal pins to match a new key, and put it back together. You end up with hardware you already like and a key set nobody else holds.
Most people who search for rekey locks near me are really asking one question: who else has a key to my door? Rekeying answers it. The reason varies. It might be a house rekey after closing on a purchase, an apartment lock rekey between tenants, or a business lock rekey after someone leaves the payroll. The work underneath is the same.
A rekey is not a repair and it is not an upgrade. It will not make a weak lock stronger, and it will not fix a door that sticks. If your hardware is worn, low-grade, or damaged, we tell you that plainly and lay out the other options, which we cover below.
When should you rekey your locks in El Monte?
The short rule: rekey whenever you cannot say for certain who holds a working key. These are the situations we hear about most often.
- Rekey locks after moving. Previous occupants, their relatives, landlords, cleaners, and contractors may all have copies, and you have no way to count them.
- Rekey locks after buying a house. Sellers and agents hand over the keys they know about, not the copies made over the years. Doing it before you unpack is the cleanest time.
- Rekey locks after a tenant moves out. Keys go missing, get copied, or stay in a pocket. A tenant turnover rekey puts the unit on a fresh key without buying new hardware.
- Rekey locks after losing keys. If the keys disappeared along with anything showing your address, treat them as compromised. If a key vanished inside your own home and turned up a day later, you may not need to do anything.
- After a roommate, partner, or caretaker leaves. Someone you trusted last year may not be someone you want holding a key now.
- When you want fewer keys. You can rekey all house locks to one key so the front door, back door, and any side entry open with the same key in your pocket.
How we handle a rekey, step by step
Here is how a typical visit runs, whether it is one door or a whole house.
- You call (213) 577-1366, at any hour. Tell us how many locks there are, what kind they are (deadbolt, knob, lever, screen door), and whether you want them all on one key.
- We tell you whether the job sounds like a straightforward rekey and what could change that once we see the hardware. Some locks can only be judged in person, and we say so.
- A technician comes to you in a mobile van with the tools and parts for rekeying. Before touching a lock, we ask you to show that you own, rent, or manage the property.
- We look over each lock first: how the cylinder turns, whether the bolt lines up with the strike plate, and whether anything is worn or loose. Anything likely to cause trouble later, we point out before we start.
- We rekey each cylinder and cut the new keys. Where the locks allow it, every door goes on the same key.
- We test every lock with the new key, door open and door closed, then try an old key to confirm it no longer turns.
- We hand over the keys and explain what to do with them. If you need spares for family or staff, we can cut copies through our key duplication service.

Call (213) 577-1366Should you rekey or replace the lock?
Rekeying is usually the more economical route when the hardware is in good shape, because you keep what you already paid for and only change the key pattern. Replacement makes sense when the lock itself is the problem. If you already know you want new hardware, our change locks and lock replacement pages explain that path.
Older homes need a little extra attention. A lot of El Monte's postwar housing still carries original mid-century locksets. Some are fine to rekey. Others have worn internals or unusual cylinders where a clean rekey is not realistic, and we would rather tell you that at the door than hand you a lock that works poorly. Often the answer is swapping only the cylinder instead of the whole set.
- Rekey when the lock turns smoothly, the finish is acceptable, the grade is decent, and you only want to cut off old keys.
- Replace when the lock is loose, worn, corroded, or damaged, when parts are hard to find, when you want a stronger grade, or when you want something different such as a smart lock.
- Add hardware when the door only has a knob lock. Rekeying cannot add a deadbolt, but deadbolt installation can.
How much does lock rekeying cost in El Monte?
We do not put numbers on a web page because the honest answer depends on the job, and a figure written here would be wrong for half the people reading it. What we can do is show you what moves the total.
Ask any locksmith what the quote includes before work starts: the visit, each lock, the keys, and any parts. We will tell you what the job involves and what is driving the total as we find it. If a rekey will do, we say so rather than sell you hardware you do not need.
- How many cylinders. Every lock is its own piece of work. A single front door and a full house with a back door, side entry, and screen door are very different jobs.
- Lock type and brand. Common residential locks are quick to rekey. Higher-security cylinders, restricted keyways, and older or unusual locks take more time or special parts.
- Condition. A worn cylinder may rekey poorly. If a part needs replacing, the work and the total change.
- How many keys. Extra copies for a family, a property manager, or staff add to the job.
- Keyed alike or separate. Putting several locks on one key, or keeping units separate, changes how we pin the cylinders.
- When and where. After-hours calls can affect the total, and distance matters: our Westwood storefront is about 25 miles from El Monte.

Call (213) 577-1366Tenant turnover rekey and rental properties in El Monte
El Monte has a substantial renter share, along with many small apartment complexes and backyard accessory units. That means a lot of doors change hands. A tenant turnover rekey is the usual fix: keep the same locks, change the keys, and start every new occupant with a set that only they and you hold.
For landlords and property managers, the useful habits are simple. Rekey every time a tenant leaves, not only when a key is reported lost. Keep a written record of which keys went to whom. Decide whether each unit gets its own key or whether a shared door, like a laundry room or gate, needs a separate one. Our locksmith for landlords page covers managing several units.
If you are a tenant, check your lease and talk to your landlord before changing any lock. We are locksmiths, not lawyers, and we will ask you to show you are entitled to authorize the work. For a backyard unit, keep its keying separate from the main house so one key never opens both.
Commercial rekey and business lock rekey
A commercial rekey follows the same logic as a house, with more doors and more people holding keys. The usual triggers are an employee or manager leaving, a new tenant taking over a suite, a missing key, or a business that has simply lost track of how many copies are out there.
Commercial lock rekey work often depends on the keying plan. A small shop may be fine with one key for the front and back. A larger operation may need different keys for different people, with a few that open everything. That is where a master key system comes in, and it is worth planning before we pin any cylinders, because it is hard to add afterward.
For repairs, replacement, or broader hardware work on a business, see our commercial locksmith page. Rekeying only changes who can open the lock. It does not fix a failing door closer or a worn latch, and we will flag those if we see them.
Lock rekey around Five Points, Mountain View, Flair Park and the rest of El Monte
We work across both El Monte ZIP codes, 91731 and 91732, and the local housing and business mix shapes what rekey calls look like here.
Much of the housing is postwar bungalows and small ranch homes. In Five Points, Mountain View, Norwood Village, Arden Village, and the Zamora Park area, a house rekey often means more than one door: the front entry, the back door, and sometimes a detached garage or a backyard unit. Original mid-century locksets are still widespread on this older stock, so we check each one before promising a clean rekey. Security screen doors are a common retrofit on denser blocks, and they carry their own lock. If you want the screen door on the same key as the main door, tell us at the start so we can see whether that lock allows it.
Picture someone who has just bought a bungalow in Five Points. The sensible first-day step is to rekey all house locks, check that each door still closes cleanly, and cut keys for the household. That is an illustration, not a past job.
Downtown, around the Valley Mall pedestrian shopping district, storefront rekeys make sense when a shop changes hands or a manager leaves. In the Flair Park business district, an office suite rekey makes sure only current staff hold keys. In the Northwest Industrial District, warehouse and roll-up door lock work is its own category, so tell us which lock types you have when you call. Apartment lockouts near the El Monte Station transit center are a typical scenario here, and if the keys are lost rather than just locked inside, a rekey is the sensible follow-up.
El Monte sits in a flat San Gabriel Valley basin with hot, dry summers and little coastal cooling. The main seasonal issue for locks is heat-driven expansion of wood doors and frames, so a bolt that slides freely in spring can drag in August. When we rekey a wood door, we test the bolt against the strike. If the drag comes from the door instead of the lock, we say so. Rekeying will not fix that, but a strike adjustment or door work may.

Call (213) 577-1366Why call Wilshire Lock & Key for a rekey?
We have been in business since 1987. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties. When you call (213) 577-1366, you reach us, not a dispatch middleman who sells your job to whoever is closest. One company answers and one company shows up.
David, the owner and lead technician, oversees the work. Rekeying looks simple, and in many ways it is, but small mistakes like a pin set wrong or a bolt left untested show up later as a key that sticks.
California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith for that license number before work starts. It is a fair question to put to us too.
Rekeys are done at your door, which is exactly how our mobile locksmith service works: we come to the lock instead of asking you to bring it in. Our phone is answered around the clock, every day of the year.
Frequently asked questions
How long does a lock rekey take?
It depends on how many locks there are and what kind. One standard lock is quick work, and a whole house takes longer. Tell us the count when you call and we will give you a realistic sense of the visit. We will not promise a time we cannot keep.
Does rekeying make my home more secure?
It makes it more secure in one specific way: old keys, including copies you never knew about, stop working. It does not make the lock harder to pick or force, and it will not strengthen a weak door. If you want a stronger lock, that is a replacement or upgrade conversation.
Can you rekey all my house locks to one key?
Usually yes, when the locks are compatible. Some brands, older locksets, and many screen door locks may not accept it. We check each lock when we arrive and tell you which ones can share a key before we begin.
I just moved into a rental in El Monte. Should I rekey?
Many tenants want to, and it is reasonable, but speak to your landlord first. Your lease may say who handles lock changes. Ask for permission in writing, and if the landlord prefers to arrange it, they can call us directly.
Can every lock be rekeyed?
Most standard residential and commercial locks can. Worn, damaged, or very old locks sometimes cannot be rekeyed cleanly, and some restricted high-security cylinders need special handling. We confirm what is possible when we see the lock and recommend a cylinder swap or replacement when a rekey would be a poor fit.
Do you rekey businesses and office suites in El Monte?
Yes. We rekey storefronts, office suites, and warehouse doors. If you have several people who need different levels of access, mention it on the first call so we can plan the keying before pinning any cylinders.
Can I get a rekey at night or on a weekend?
Our phone is answered 24 hours a day, seven days a week, at (213) 577-1366. Call and tell us the situation. If you are locked out or exposed, we treat that first; if it can wait, we can schedule the rekey for a convenient time.
What do I need to show before you rekey a lock?
We ask you to show that you own, rent, or manage the property, such as ID that matches the address, a lease, or a management agreement. It protects residents and owners, and any reputable locksmith should ask the same.
Should I rekey or just change the locks?
If the hardware works well and you like it, rekeying is usually the more economical route. If the lock is worn, damaged, or you want a different grade or style, replacing it makes more sense. We look at the lock and tell you which fits.
