What does it mean to rekey locks?
Rekeying is the simple part of locksmith work, and it is often the smartest. Inside a standard pin-tumbler lock there is a row of small pins that line up only when the correct key is inserted. To rekey a lock, we take the cylinder apart, swap the pins for a new combination, and cut keys that match it. The lock body, the deadbolt, the handle, and the finish on your door all stay put. What changes is which keys work.
The result is that every key that used to open the door, including the one a previous owner kept, the copy a former roommate made, and the spare you lost somewhere, becomes a piece of scrap metal. You get new keys, and the old ones no longer turn anything.
People often use the terms interchangeably, so here is the difference. Rekeying changes the inside of a lock you already own. Replacing swaps the whole lock for a different one. If you want a different look, a stronger grade, or a smart lock, that is a replacement or installation job. If you simply want to control who has access, rekeying is usually the more economical route, and it is what this page is about.
A rekey can also put several locks on one key. If your front door, back door, side gate, and garage entry each take a different key, we can bring them onto a single key pattern so you carry one instead of four. That is a common request when someone is rekeying all house locks at once.
When should you rekey your locks?
There is no schedule that says every lock needs rekeying every few years. It comes down to whether you know who holds a key. These are the situations we hear about most often.
- Rekeying locks after buying a house. You do not know how many keys the sellers, their agent, a contractor, a cleaner, or a dog walker kept. Closing day is the natural moment to reset all of it.
- Rekeying locks after moving into a rental or a new apartment. The previous tenant may have left, but their keys did not necessarily go back to the landlord.
- Rekeying locks after a tenant moves out. If you own a rental, tenant turnover rekey is standard practice. It keeps the unit under your control and stops disputes about who still has access.
- Rekeying locks after losing keys. If the keys vanished with no address attached, you may only be misplacing them. If a wallet or bag went missing with your address or a car registration in it, rekeying is the sensible response.
- After a breakup, a roommate change, or an employee leaving. Anyone who once had a key and no longer should is a reason to change the combination.
- After a remodel or major construction. Crews often get keys, or the house is left open and keyed to a lockbox for weeks.

Call (213) 577-1366How we rekey your locks, step by step
Rekeying is quick work for a trained locksmith, but it should still be done carefully. Here is how a typical visit goes, whether we come to you or you bring cylinders to our Westwood storefront.
- You call (213) 577-1366 and a person answers, any hour. Tell us how many locks you have, what type they are (deadbolt, knob, lever, handleset), and why you want them rekeyed.
- We confirm the plan before we head out. We ask about brand and condition so we bring the right pinning kits and parts. If a lock looks worn or damaged from the description, we say so up front.
- At your door, we inspect each lock first. A lock that is stiff, loose, or corroded may not be a good candidate for rekeying, and we tell you before we start work, not after.
- We remove each cylinder, take out the old pins, and install a new pin combination. Where it makes sense, we match all locks to one key.
- We cut new keys and test every lock several times: key in, key out, bolt thrown, bolt retracted. We also confirm that the old key no longer works.
- You get your new keys, and we go over how many you want as spares. If you want extra copies later, we can do that through our key duplication service.
How much does lock rekeying cost in Manhattan Beach?
We do not quote a flat figure over the web because honest pricing depends on what is actually on your door. Here is what moves the cost up or down.
The number of cylinders is the biggest factor. Rekeying one deadbolt is a small job, and rekeying a whole house with a front door, back door, garage entry, and side gate is a larger one, though the per-lock effort usually drops as the count goes up because we are already set up on site.
The brand and type of lock matters. Common residential brands are straightforward. Some high-security cylinders, restricted keyways, and older or unusual hardware take more time or require specific parts. If a key control system limits who may copy your keys, that affects how we cut them.
The number of keys you want cut counts too. A single key is simple, and a set for a household or a rental portfolio takes longer.
Condition also plays a role. Salt air is hard on exterior hardware in Manhattan Beach, and a lock that is corroded or dragging may need repair or replacement before rekeying is worth doing. That changes the scope, and we will say so plainly.
Timing and travel factor in. A scheduled daytime visit is different from a middle-of-the-night call, and distance from our storefront matters for a mobile visit.
In most cases, rekeying is the lighter-cost option compared with replacing every lock, because you keep the hardware you already paid for. We give you the details of the job before we begin, and you decide whether to go ahead.

Call (213) 577-1366Should you rekey or replace your locks?
Rekeying is not always the right answer. We would rather tell you that than do a job that does not help you.
Rekey when the locks are in good working order, you like how they look, and your only concern is who holds a key. This covers most post-move and post-tenant situations.
Replace when the lock is damaged, worn, or visibly corroded, when it is a low-grade lock you want to move away from, or when you want a different feature. If you are thinking about new hardware across the house, our lock replacement and change locks pages explain how those jobs differ from a rekey.
Replace also if you want keyless entry. A rekey does not turn a deadbolt into a smart lock. If that is where you are headed, see our smart lock installation page. Many newer homes in the area already use smart systems, and those are rekeyed or reconfigured differently from a conventional pin cylinder, so mention it when you call.
One honest caution: rekeying changes who can open the lock with a key, but it does not make a weak lock strong. If your deadbolt is flimsy or the strike plate is loose, a rekey will not fix that. We will point it out during the inspection and let you decide.
Rekeying in Manhattan Beach: what we see around town
Manhattan Beach is mostly single-family homes, and that shapes the kind of rekeying people ask for. Here is how it plays out in a few parts of the city, all within ZIP code 90266.
In the Tree and Hill Sections, rekeying after sales and remodels is a regular scenario. Mid-century homes change hands, and many are torn down and rebuilt or heavily renovated. Between the sellers, agents, inspectors, and construction crews, a lot of keys float around. Rekeying the exterior locks when you take possession puts you in control. For new construction, the high-end and smart-lock hardware common on these builds is worth discussing before we arrive.
In the Sand Section, the walk-streets mix older 1920s to 1940s cottages with newer custom rebuilds. Many older cottages still carry their original door hardware, which can be rekeyed if it is in decent shape. But parking and access on the walk-streets are tight, and the beachfront location is hard on metal. Salt air steadily corrodes exterior hardware, especially along The Strand, and the persistent marine layer dampness can swell wood doors and stick latches. If a lock is sticky because the door has swollen rather than because the cylinder is worn, rekeying will not fix it. We check that first, so you do not pay for the wrong job. Our mobile vans handle the tight-access streets, and you can read more on our mobile locksmith page.
East Manhattan Beach is dominated by 1950s and 1960s single-family tracts, where original locks may have been through several owners. A full-house rekey after a purchase is a natural step there.
Manhattan Village is a gated condominium and townhome community near the mall, and townhomes and condos also concentrate toward Rosecrans Avenue and the north end. In those, the common gate or building entry is typically controlled by an association, while your unit door is yours. We rekey your unit lock. For anything controlled by the association, you will need to coordinate with them.
In El Porto, near Highland Avenue, apartments and duplexes turn over regularly, which makes tenant turnover rekeying a routine need for owners and property managers there.

Call (213) 577-1366Apartment, landlord, and commercial rekeying
Apartment lock rekey is a little different from a house. A tenant typically has one entry door and perhaps a patio slider. If you are the tenant, check your lease and talk to your landlord before changing a lock, since many leases require that the landlord keep access. If you are the landlord, rekeying between tenants is a straightforward way to keep control of your units. We work with owners and managers on this through our locksmith for landlords service, including setting up consistent key records across several units.
Commercial rekey and business lock rekey follow the same basic principle but add some complexity. A shop, office, or restaurant may have multiple doors, back-of-house locks, and keys held by many employees. When someone leaves, or when a set of keys goes missing, rekeying is the quick way to reset access without tearing out hardware. Downtown along Manhattan Beach Blvd, storefront doors and panic hardware get steady use, and the cylinders in them are often rekeyable even when the rest of the hardware needs attention. If you have a more complicated setup, with different employees needing different access, a master key system can organize it so a manager's key opens everything while each staff key opens only what it should.
For broader business needs beyond rekeying, such as door hardware repair, closers, or access control, our commercial locksmith page covers what we do. This page stays focused on changing the keys.

A word about choosing any locksmith, including us: California requires locksmith companies to hold a BSIS LCO license. Ask whoever you call for it, and be cautious of anyone who cannot give you a straight answer. Also be wary of anyone who gives a low number on the phone and then changes it at your door. We explain what affects the cost before we start, and we tell you if rekeying is not what your lock needs.

A few details make the call faster and the visit smoother.
- How many locks you want rekeyed, and which doors they are on.

- Whether you want everything on one key or separate keys for certain doors.
- How many keys you want when we finish.
- Whether any locks are sticky, loose, or corroded, since that may change the plan.

Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps your existing lock hardware and changes the internal pins and keys, so old keys stop working. Changing or replacing locks swaps the hardware itself. Rekeying is usually the more economical route when your locks are in good shape and you only need to change who has access.
Can you rekey all the locks in my house to one key?
Usually yes. If the locks are compatible, we can rekey the front door, back door, garage entry, and side gate to a single key. Some specialty or restricted-keyway locks may not match others, and we confirm that at inspection.
Should I rekey locks after buying a house in Manhattan Beach?
It is a smart step. You cannot know how many keys sellers, agents, contractors, and others kept. Rekeying the exterior locks when you take possession resets access. This is especially common with sales and remodels in the Tree and Hill Sections.
Do I need to rekey after a tenant moves out?
If you own the rental, yes, it is standard practice. A tenant turnover rekey makes sure old keys no longer work and keeps the unit under your control. If you manage several units, we can help keep consistent key records.
I lost my keys. Do I need to rekey or can I just make copies?
If the lost keys could be tied to your address, rekeying is the safer move, because copies of the remaining keys would not stop the missing one from working. If you know exactly where they are, you may not need it. Call (213) 577-1366 and we can talk through your situation.
Will salt air in Manhattan Beach affect whether my locks can be rekeyed?
It can. Beachfront exposure corrodes exterior hardware, especially near The Strand and in the Sand Section. If a cylinder is only lightly affected, it may rekey fine. If it is badly corroded or the door has swelled from marine layer dampness, we may recommend repair or replacement instead, and we will explain why.
Can you rekey a smart lock?
Smart locks that have a conventional key cylinder can have that cylinder rekeyed, but the electronic side is managed through codes or the app, not pins. Tell us the brand and model when you call and we will tell you what applies.
Can you rekey commercial and business locks?
Yes. We rekey business locks, including storefront doors and back-of-house locks, and can organize larger setups with a master key system. Some commercial or high-security cylinders have restricted keys, so tell us the brand when you call.
Do I have to be home while you rekey my locks?
Someone authorized to approve the work should be there, at least at the start and end, so we can confirm which locks to change and hand over the new keys. If you are not the property owner, we may ask for confirmation that you are allowed to make the change.
Do you offer rekey service at night or on weekends?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round. Timing can affect the cost, and we explain how before we start.
