What does a lock rekey actually do?

A rekey changes the inside of a lock so that a different key operates it. Most residential locks are pin tumbler locks. Inside the cylinder sit small spring-loaded pins of varying lengths, and the cuts on your key lift each pin to exactly the right height so the cylinder can turn. When we rekey, we take the cylinder apart, swap the pins for a new combination, and cut fresh keys to match. The old key still slides into the lock, but it no longer lifts the pins correctly, so it will not turn.

The lock itself stays on the door. The knob, the deadbolt, the finish and the hardware you already chose are all untouched. That is why rekeying is often the more economical route when the only problem is who holds a key, not the condition of the lock. Nobody needs to patch the door or drill new holes, and the work happens at your door, not in a shop.

People search for this under a lot of names: rekey locks, lock rekeying, house rekey, home lock rekey, rekey door locks. They all mean the same job. If you have heard the phrase rekey all house locks, that usually means every exterior lock on the home gets set to one new key, so you carry a single key instead of a ring of them.

When does rekeying make sense for a Duarte home or rental?

Almost every rekey call starts with one question: who might still have a key to this door? You rarely know the answer, and that uncertainty is the whole reason to rekey. These are the situations we see most.

  • Rekey locks after moving: you do not know how many copies the previous occupant made, or who they handed them to. Neighbors, relatives, a cleaner and a former contractor can all be holding one.
  • Rekey locks after buying a house: the seller hands over keys at closing, but nothing tells you how many others exist. Many buyers rekey on the first day, before the first night in the house.
  • Rekey locks after a tenant moves out: a tenant who leaves on good terms may still have a key in a drawer or a car. Tenant turnover rekey is the standard way to make sure the next tenant is the only one with access.
  • Rekey locks after losing keys: if a key went missing, especially with an address attached to it or in a place you cannot trace, changing the lock is cheaper in worry than waiting to see what happens.
  • A key that was shared and now should not be: an ex-partner, a roommate who left, a caregiver, a worker who finished the job.

How we handle a rekey, step by step

Here is how a typical rekey visit goes. The order matters, because the goal is to leave you with locks that work smoothly and a set of keys you can count.

  1. You call (213) 577-1366 at any hour. A person answers, and we ask what you are rekeying: how many doors, what kind of locks, and whether you are locked out or just planning ahead.
  2. A mobile van comes to the property. If you are in a hurry because you just closed on a house or a tenant just left, tell us. We will work out the order of doors with you.
  3. We check each lock before touching it. A lock with a worn cylinder, a bent latch or a loose body may not be worth rekeying, and we say so before starting.
  4. We remove each cylinder, replace the pins with a new combination, and reassemble it. Locks of the same brand can often be keyed alike, so one key opens the front door, back door and side gate lock if you want that.
  5. We cut new keys and test them in every lock. We also test the old key and confirm it no longer turns.
  6. We hand you the keys and explain what was done to each door. If you want extra copies, we can cut them on the spot, and our key duplication service covers spares for family members.

How much does lock rekeying cost in Duarte?

We do not quote numbers on a web page because the honest answer depends on your doors, and a made-up figure helps nobody. What we can do is tell you exactly what moves the cost, so nothing surprises you on the phone.

Rekeying is priced by the work involved, and the work is usually modest compared with replacing hardware. If a locksmith quotes you for new locks when you only asked to change keys, ask why.

  • Number of locks: each cylinder has to be opened, repinned and tested, so a single back door is a smaller job than a whole house.
  • Type of lock: standard knobs and deadbolts are simple. High-security cylinders, restricted keyways and some older or unusual brands take more time, and parts may be harder to find.
  • Condition of the lock: a lock that is worn, sticky or damaged may need repair or replacement first, which adds to the job.
  • Number of keys you want: more copies mean more cutting.
  • Timing and location: after-hours, weekend and holiday calls involve different logistics than a scheduled daytime visit, and Duarte is roughly 33 miles from our Westwood storefront, so travel is part of the picture.
  • Keyed-alike or master-keyed requests: setting several locks to one key is normal. A full multi-level system is a bigger design job.

Should you rekey or replace the locks?

Rekeying is the right choice when the lock is in good shape and you only need the keys changed. It is the wrong choice in a few cases, and we would rather tell you that on the doorstep than sell you a job that does not solve your problem.

Replace instead when the hardware is broken, badly worn, loose in the door, or no longer matches the security level you want. If you want a different style or finish, or a stronger deadbolt, then a lock replacement or a full lock change is the better fit. Rekeying alone does not upgrade the strength of a lock. A cheap lock rekeyed is still a cheap lock, just with keys only you hold.

Many older homes in Duarte still carry original mid-century locksets. Some of these rekey fine. Others have worn cylinders or parts that are no longer made, and we confirm which category yours falls into when we look at it. If a lock cannot be rekeyed reliably, we tell you before doing anything.

Rekeying homes around Duarte: what local houses tend to need

Duarte is mostly postwar single-family housing, built from the 1940s through the 1960s along the Huntington Drive flats. Ranch homes and modest bungalows dominate, and many still carry their original locksets and garage hardware. A house that has changed hands a few times can have had its keys copied a dozen times without anyone keeping track. For those homes, a first-day rekey after a sale is simple, sensible and quick to explain to the new owner.

Up on Duarte Mesa and in the canyon areas, Fish Canyon, Mel Canyon and Spinks Canyon, the lots are larger and many homes are custom builds. That usually means more doors than a flatland bungalow: a front door, a patio or slider, a side entry, a garage service door, maybe a guest house or a gate. Rekeying hillside homes after a sale or a tenant turnover is one of the most common jobs here, and the useful part is getting every door onto one key so you are not juggling a ring. For gates and padlocks on larger lots near Fish Canyon, we can set those to the same key as the house when the hardware allows it.

The Santa Ana winds that funnel out of the canyons and the dry summer heat have a practical effect on exterior locks. Grit builds up inside cylinders, and sun-exposed doors expand slightly, so keys start to stick or turn hard. Rekeying means the cylinder is opened and handled anyway, which is a good moment to see whether grit or wear is the real problem. If a lock is gritty, we clean or flag it. If a cylinder is worn past saving, we say that too.

Townhomes and apartments cluster near Huntington Drive and the City of Hope campus, in the 91010 ZIP code. A landlord with a unit near the campus may turn it over to a new tenant who just arrived for treatment or work, and the tenant's first question is often whether the last occupant's keys still work. A rekey answers that cleanly. If you are locked out of a unit while sorting this out, our apartment lockout page covers that separate situation.

Apartment, landlord and tenant turnover rekeys

Apartment lock rekey work has its own rhythm. Units turn over, and every turnover raises the same question: how many keys are out there? Handing the next tenant a new key to a lock that still works with three old ones is a gap, and many landlords close it every time.

For landlords and property managers, the practical approach is to rekey between tenants rather than waiting for a complaint. We can work through a building door by door, set each unit to its own key, and keep a clear record of what was done so your own files are tidy. If you manage several properties in the area, our page for landlord locksmith work covers the wider picture, including how to keep turnovers consistent.

If you are a tenant, check your lease and talk to your landlord before rekeying. In many rentals the landlord controls the locks, and changing them yourself can cause problems. If the landlord asks us to do the work, we are glad to coordinate.

Commercial and business lock rekey

Commercial rekey is the same principle with more at stake. When an employee leaves, a lease changes hands, or a key ring goes missing, you want the old keys dead without ripping out your hardware. Business lock rekey is also often less disruptive than replacement, since the doors, closers and exit devices stay where they are.

Along the Huntington Drive business corridor and Buena Vista Street corridor, shops and small offices tend to have one or two entrances and a back door. A commercial lock rekey there is usually a short visit. For businesses with several employees and different access levels, a master key system lets each person carry one key that opens only what they should. For bigger needs, such as exit hardware or door closers, our commercial locksmith page explains what else we handle.

Why call Wilshire Lock & Key for a rekey in Duarte?

We have been in business since 1987, and rekeying is some of the oldest work in the trade. We are a single company, not a call center that passes your job to whoever is free. When you phone (213) 577-1366, you reach us, and the same company sends the van.

We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile vans, and we serve 140 cities across Los Angeles and Ventura counties, Duarte included. Because we are mobile, the work is done at your door, with parts and key machines in the van. You do not need to bring locks to us. If you want to know more about how the vans work, see our mobile locksmith page.

David, the owner and lead technician, oversees the work. That matters on a rekey because small details decide whether it goes well: whether the pins are set correctly, whether the old key is truly dead, whether the lock is worth keeping. We answer calls 24 hours a day, 7 days a week, year-round, so you can arrange a rekey the night you close on a house or the night a tenant hands back keys.

How to choose a locksmith for rekeying

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for that license number before they start work, including us. A real company will give it to you without hesitation.

Other things to look for: a locksmith who tells you what the job will involve before arriving, who looks at your locks before suggesting replacement, and who does not push you toward new hardware when a rekey will do. Be cautious about a company that cannot tell you where it is based or who is actually coming. Ask who will arrive and whether the person who answers the phone is part of the company that sends the van.

Frequently asked questions

What is the difference between rekeying and changing locks?

Rekeying keeps your existing lock hardware and changes the pins inside so a new key works and the old one does not. Changing or replacing locks means installing new hardware. If your locks are in good shape, rekeying is usually the more economical route.

Do I need to rekey after buying a house in Duarte?

It is strongly worth doing. You cannot know how many copies of the previous owner's keys exist or who holds them. Rekeying on or soon after move-in means only keys you hold will open your doors.

Can you rekey all the locks in my house to one key?

Usually yes. Rekeying all house locks to one key is a common request, and many same-brand locks can be keyed alike. Some older or unusual locks may not combine with the rest, and we tell you which ones when we look at them.

How long does a rekey take?

It depends on how many locks there are and what condition they are in. A single door is a short job, and a whole house or building takes longer. We give you a realistic idea when you call and confirm once we see the locks.

Will my old key still work after a rekey?

No. The old key may still go into the lock, but it will not turn the cylinder. We test the old key after the job to confirm it is dead.

Can you rekey a lock if I have lost every key?

Yes, in most cases. If you are locked out, we need to get you in first, and the house lockout service covers that. Then we can rekey the lock so the lost key no longer works and cut you new keys.

Do you rekey commercial doors and storefronts in Duarte?

Yes. We handle commercial lock rekey for shops, offices and other businesses, including after staff changes or a lease change. Call (213) 577-1366 and tell us how many doors and what kind of hardware you have.

Should a landlord rekey between every tenant?

Most property managers do, because you cannot be sure every key came back. It is a straightforward way to make sure the new tenant is the only person with access to the unit. Check your lease and local rules about who controls the locks.

Are there locks that cannot be rekeyed?

Yes. Some very worn locks, certain older mid-century sets, and some specialty or proprietary locks cannot be rekeyed reliably, or need parts that are hard to get. We check each lock and tell you before working on it whether rekeying or replacement makes more sense.

Do you come out to Duarte at night or on weekends?

Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, and our mobile vans serve Duarte and the 91010 area. Tell us your address and what you need and we will go from there.
