What does a lock rekey actually do?

Rekeying changes the internal pin arrangement of a lock cylinder so that a new key operates it and every earlier key becomes useless. The knob, lever, or deadbolt stays on your door. You keep the hardware you chose and the finish you like. Only the part that recognizes a key is changed.

People find this page searching for things like rekey locks near me, house rekey, or home lock rekey, and they almost always have the same story behind it: they just moved in, a tenant left, or a set of keys went missing. The goal is identical in every case. You want to know exactly who holds a working key to your door, and you want the answer to be only the people you chose.

In South Pasadena this matters a little more than in a newer suburb, because so many doors here carry original hardware worth keeping. A rekey lets you change who has access without pulling off a hundred-year-old lockset or drilling a historic door to fit something new.

When should you rekey your locks?

Rekeying is the right move any time the question is who has keys, rather than whether the lock itself still works. These are the situations we see most often:

  • Rekey locks after moving: you do not know how many copies the previous occupant made, or who they gave them to.
  • Rekey locks after buying a house: sellers, agents, contractors, inspectors, and past owners may all have had keys over the years. A rekey of all house locks at closing resets that.
  • Rekey locks after a tenant moves out: the tenant turnover rekey is the standard way to hand a unit to the next person without carrying over the last person's keys.
  • Rekey locks after losing keys: if the keys went missing somewhere that could be linked to your address, do not wait to find out whether anyone picks them up.
  • After a falling out: an ex-partner, a former roommate, a contractor, a house cleaner, or a caretaker who still has a key and no longer should.

Rekey or change the locks: which one fits?

If your hardware is in good shape and you like it, rekeying is usually the more economical route, and it keeps the look of the door intact. If the hardware is worn, loose, damaged, or simply not secure enough for how you want to live, then changing the locks or a full replacement makes more sense. We will tell you which one you actually need after looking at the locks, not before. A rekey does not make a weak lock stronger. It only makes the keys new.

How does a rekey visit work, step by step?

There is nothing mysterious about it, and you are welcome to watch every part. Here is how a typical visit goes:

  1. You call (213) 577-1366. Tell us how many locks are involved, what kind they are (deadbolts, knobs, levers, older mortise sets), and whether you want them all to use one key.
  2. We come to your address in one of our mobile vans, carrying the pins, tools, and key blanks for the common lock types we see. Because South Pasadena is about 20 miles from our Westwood storefront, we will confirm timing with you when you call.
  3. We ask you to confirm that you live at the property or are authorized to manage it. We do this because we will not change access to a place for someone who has no right to it.
  4. We look over each lock before touching it. If a cylinder is too worn, damaged, or non-standard to rekey reliably, we say so and explain your options.
  5. We remove each cylinder, replace the pins to match a new key, cut the new keys, and reinstall.
  6. We test every lock with the new key, and with an old key if you still have one, to confirm the old key no longer turns.
  7. We hand over the new keys and talk through spares so you are not caught out the first time someone needs a copy.

How much does lock rekeying cost in South Pasadena?

We do not publish numbers here, because the real figure depends on your doors and not on a flat rate. What we can do is tell you exactly what moves the cost, so you can judge any quote you receive from us or anyone else.

A rekey is generally the lighter-cost option compared with replacing hardware, as long as your locks are sound. Once we hear what you have, we can give you a clear quote before any work begins.

  • Number of cylinders: every lock you want rekeyed is its own piece of work, so a single back door is a smaller job than a whole house.
  • Type and condition of the locks: standard residential deadbolts are straightforward, while older or unusual cylinders take more time and sometimes more parts.
  • Keyed alike or separate: putting every door on one key is convenient, but it is a deliberate choice that affects how we set up the job.
  • Number of keys: more copies means more cutting.
  • Restricted or high-security keyways: these have controlled key blanks and are not handled like a basic hardware-store key.
  • Time of day: after-hours and weekend calls are different from a scheduled daytime visit.
  • Travel: we serve South Pasadena from Westwood, and distance is part of the picture.
  • Repairs found along the way: if a lock is sticking or damaged, fixing it is a separate item and we will tell you before we do it.

Rekeying in Mission West, Raymond Hill, and Altos de Monterey

South Pasadena, ZIP 91030, is a small, preservation-minded city where the housing varies a lot from one hillside or street to the next, and that changes how we approach a rekey.

Take the Craftsman homes around the Mission West district. Many were built between the 1890s and 1930s, and plenty still have their original hardware. Vintage lockset repair and rekeying is a regular kind of call in that area. Owners there are often more interested in protecting what is original than in modernizing, and a rekey fits that well. Older sets can be less predictable than a modern deadbolt. Some rekey cleanly, some need a replacement cylinder, and a few have worn parts that make us suggest repair first. We will tell you plainly which you have.

Summer heat can swell older wood doors, so a lock that binds in July is sometimes a door problem, not a key problem. Weather-driven lock wear here is modest, though, so for most owners the reason to rekey is key control, not corrosion or damage.

Up on the southwest hills, Altos de Monterey is mostly 1960s mid-century homes. Hardware in those houses is often a mix: some original, some replaced over the decades by different owners, which is exactly why a rekey after buying a house is worth doing. Different locks on one home can have different brands and different key types, and we can bring them onto one key if you want that.

Then there are the apartments and condos near Fair Oaks Avenue and on Raymond Hill. Condo lockouts on Raymond Hill are a recurring situation, and they often lead straight to a rekey, because someone who cannot find their keys has to decide whether those keys are lost or taken. If you rent or own a condo there, check with your association or landlord about what changes to door hardware are allowed before we start.

Tenant turnover rekey for apartments and rental units

For a landlord or property manager, the apartment lock rekey between tenants is the simplest way to make sure the last occupant's keys no longer work. It is faster and more economical than replacing every lock, and the next tenant gets keys that nobody else holds. Along the Fair Oaks Avenue corridor, where apartments cluster, the same approach can cover several units in one visit.

If you manage multiple doors, tell us up front. We can set units up on their own keys, or arrange a hierarchy where an owner or manager key opens several doors while each tenant's key opens only theirs. That is a master key system, and it is worth planning before the first rekey rather than adding it later.

For owners with several properties or rotating tenants, our page for landlords and property managers covers the wider picture. If a tenant is already locked out of a unit while you are sorting this, that is a different call, and our apartment lockout service handles it.

One caution. Rules about who may change locks and when are set by your lease and by state law, and we cannot give legal advice. If you are unsure whether you may rekey a particular unit, settle that first. We will rekey what you are entitled to have rekeyed.

Commercial and business lock rekey on Mission Street

Commercial rekey follows the same logic as a house, with a few extra pressures. A shop on the Mission Street business district, near Mission Station on the Metro A Line, may have had several employees, a former manager, a landlord, and a cleaning crew all holding keys. When someone leaves, or you simply cannot account for every copy, a business lock rekey puts that to rest without replacing the storefront hardware.

We can rekey the front door, back door, and any interior or office locks, and set them up so staff get only the keys they need. Storefront lock service on Mission Street is one of the common situations we see for South Pasadena businesses.

If your business needs more than a rekey, such as a full key hierarchy, new hardware, or access control, our commercial locksmith page is the right starting point. Note that panic hardware, door closers, and storefront repairs are separate services from rekeying, and we treat them that way.

When is rekeying not the right answer?

We would rather lose a rekey job than sell you the wrong one. Rekeying is not the right fix in these cases:

The lock is damaged, loose, or failing. Changing the pins in a lock that already half-works only gives you a new key for a lock that will fail soon. Here a lock replacement is the honest recommendation.

The lock was never strong enough. A rekeyed basic lock is still a basic lock. If you want better resistance to picking or drilling, high-security locks are a different class of product, and we can explain the tradeoffs.

You only need a spare. If the lock is staying as it is and you just want another copy, that is key duplication, not a rekey. Keep in mind that every copy you make is another key to account for.

Some modern locks include a built-in rekey feature, and we will tell you if yours does and what that means for the job.

Why call Wilshire Lock & Key for a rekey?

We have been in business since 1987. We run a storefront at 10740 Wilshire Blvd in Westwood, Los Angeles, CA 90024, and our mobile service vans bring the work to you. When you call, you are dealing with one company, not a call center that passes your job to a stranger. Nobody is dispatching you to a subcontractor you never spoke to.

David, the owner and lead technician, oversees how we work. The phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, so if you realize at night that a set of keys is gone, you can reach a person.

One thing to do with any locksmith, including us: ask for their license. California requires locksmith companies to hold a BSIS LCO license, and a legitimate company will give you the number without hesitation. It takes ten seconds and tells you a lot about who is at your door.

Frequently asked questions

What is the difference between rekeying and changing locks?

Rekeying keeps your existing lock and changes its internal pins so a new key works and old keys do not. Changing locks means putting new hardware on the door. Rekeying is usually the more economical route when your locks are in good shape. Changing is better when the hardware is worn, damaged, or not secure enough.

Should I rekey all the house locks after buying a home in South Pasadena?

Yes, it is a sensible first step. You cannot know how many copies of the old keys exist or who holds them. Rekeying every exterior door, plus any garage or side-gate lock you use, resets that. In an older home, we check each lock first, since vintage hardware sometimes needs different handling.

Can old Craftsman or period locks be rekeyed?

Often, yes, but each one has to be checked. Many older locksets rekey well. Some need a replacement cylinder, and some are worn enough that we recommend repair first. We will look at yours and say plainly what is possible so you can decide before we change anything.

Will my old keys still work after a rekey?

No. That is the whole purpose. After the rekey, the old keys will not turn the lock, and we test this on the spot if you still have an old key. Only the new keys we cut will operate it.

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

In many cases, yes. If the lock is locked and you have no key, we may need to open it first, and that can be a separate step. Once we have access to the cylinder, rekeying proceeds as usual. If you are locked out at home right now, our house lockout service covers getting you back in.

Can I put all my locks on one key?

Usually you can. We can set several locks to the same key, which is convenient for a house with a front door, back door, and side entry. How easily it works depends on the brands and condition of your locks, and keying them alike affects how the job is set up.

I rent my apartment. Can I rekey the lock myself through you?

Check your lease and with your landlord first. Who is allowed to change or rekey locks depends on your lease and state law, and we cannot give legal advice. If your landlord approves, we are happy to do it. If you manage the property, we will ask you to confirm that.

How much will it cost to rekey my locks?

It depends on how many locks you have, what type and condition they are, whether you want them keyed alike, how many keys you need, the time of day, and travel. Describe the job when you call (213) 577-1366 and we will go through what applies to you before work begins.

Do you handle commercial rekeys for shops and offices?

Yes. We rekey storefront doors, back doors, and interior office locks, and can set staff up with only the keys they need. For bigger key hierarchies or new hardware, we will point you toward the right commercial service.

Do you rekey locks at night or on weekends?

Our phone is answered 24 hours a day, 7 days a week, year-round. If you need a rekey outside normal hours, call (213) 577-1366 and we will tell you what is possible. Late-hour work is priced differently from a scheduled daytime visit.
