What does it mean to rekey locks?
Rekeying changes the inside of a lock so that a different key operates it. The lock body, the deadbolt, the handle and the finish all stay on your door. What changes is the set of pins in the cylinder. After the work, the key you had before no longer turns the lock, and the new key does.
That is why rekeying is the usual answer when the hardware is fine but you no longer know who holds a copy of the key. You keep locks you already paid for and shut out every key that was ever cut for the old setup. It also lets us put every lock on the property on one key, so you stop carrying a ring of mismatched keys for the front door, the back door and the side gate.
Rekeying is not a security upgrade by itself. A rekeyed lock is as strong as the lock it started as. If the hardware is worn, loose, or the wrong grade for the door, we will tell you that plainly and show you the options.
When does it make sense to rekey instead of leaving things alone?
Most of our rekey calls fall into a handful of situations. If you recognize yours below, rekeying is almost always the right first step.
- Rekey locks after moving: previous residents, their friends, a cleaner or a family member may still have keys. You have no way to know how many copies exist.
- Rekey locks after buying a house: the seller's agent, contractors, a former owner's relatives and past tenants may all have held keys during the sale.
- Rekey locks after a tenant moves out: tenant turnover is the most common reason landlords call us. A tenant who returns the key may still have kept a copy.
- Rekey locks after losing keys: if keys were lost with an address attached, or you simply cannot say where they went, changing the lock is cheaper in worry than waiting to find out.
- After a roommate, ex-partner, contractor or former employee has had access and the relationship has ended.
How does a lock rekey work, step by step?
We keep the process the same every time so nothing is missed and nothing on your door is damaged. Because we come to you with a mobile van, most rekeys are done at your door in a single visit.
- You call (213) 577-1366. We ask what kind of property it is, how many locks are involved, and what brand of locks you have if you know.
- We arrive, check each lock, and confirm it is in good enough shape to rekey. A lock that is bent, stripped, or badly corroded is flagged before we touch it.
- We remove the cylinder, take out the old pins, and rebuild it with pins matched to a new key cut for your property.
- We reinstall the cylinder and test the new key several times in each lock, checking the bolt throws fully and the latch catches cleanly.
- We confirm the old key no longer works. We hand over the new keys and, if you want every lock on one key, we align all the cylinders to it.
- If you need extra copies, we can cut them on the spot as part of key duplication so everyone who should have a key leaves with one.

Call (213) 577-1366Should you rekey or replace locks that are worn by salt air?
This is the question that matters most in Hermosa Beach. The whole city sits within a few blocks of the ocean, and salt air corrodes exterior locks, hinges and gate hardware as a matter of routine. Older beach cottages also deal with marine layer damp, which swells wood doors and makes deadbolts stick.
A rekey only works if the cylinder moves freely. If corrosion has gummed up the pins or the bolt drags against a swollen door, rekeying the lock may leave you with a new key that still sticks. In that case the honest advice is to replace the lockset, and we will explain why before you decide. You can read more on the lock replacement page.
As a rule of thumb: if the lock turns smoothly, the key goes in without force and the finish is sound, rekey it. If the key grinds, the bolt hangs up, or the lock is visibly pitted, replacing it is usually the better use of your money. When a lock is in between, we can clean and test it first so you are choosing with real information. Sometimes the better move is a full change of locks on the exterior doors while rekeying the interior ones.
How much does lock rekeying cost in Hermosa Beach?
We do not quote numbers on a web page, because the real figure depends on your doors and we would rather give you an accurate quote than a guess. What moves the cost is straightforward:
Rekeying is usually the more economical route compared with replacing every lock, because you reuse the hardware you already have.
- How many cylinders need rekeying. A single front door is a smaller job than a duplex with several entries, a garage door, a side gate and a mailbox.
- The brand and condition of the locks. Common residential brands are simple to rekey. Older, unusual, or high-security cylinders can take more time and sometimes special parts.
- Whether every lock should match one key. Setting a whole property to a single key is more work than rekeying one lock, but most owners find it worth doing.
- How many keys you need cut once the work is done.
- Time of day and urgency. A planned weekday visit and an after-hours call are different situations.
- Whether any locks turn out to be too corroded to rekey and need replacing instead.
What about rekeying for landlords, rentals and businesses?
Tenant turnover rekey is one of the steadiest parts of our work. If you manage a rental, rekeying between tenants is the simplest way to be sure the next resident is the only one with access. Doing it every turnover also removes any argument later about who had a copy. Landlords with several doors can set up a repeatable routine, and our locksmith for landlords page explains how that works with multiple units.
Commercial rekey and business lock rekey follow the same principle with a few extra considerations: staff changes, shared entrances, back-of-house doors and sometimes a hierarchy of keys. When a manager leaves or a key goes missing from a shift drawer, rekeying the affected doors closes the gap without replacing every lock. If you need different people to open different doors, a master key system lets you give each person only the access they need.
For ongoing commercial needs beyond rekeying, such as door hardware, closers and storefront locks, our commercial locksmith service covers those separately.

Call (213) 577-1366What does lock rekeying look like in Hermosa Beach neighborhoods?
Hermosa Beach is under 1.5 square miles and densely built. Small-lot beach cottages from the 1920s onward sit beside townhomes that were converted or rebuilt, and duplexes, triplexes and small apartment buildings are common, especially in the Sand Section and along the Pacific Coast Highway and Aviation Boulevard corridors. A high share of homes are rentals, so units change hands often. That is exactly where rekeying earns its place.
In the Sand Section, a typical call is a rental duplex or triplex where one tenant has moved out and the owner wants the unit secured before the next one arrives. Each unit might have a front door lock, a deadbolt and a separate gate or garage entry, and we can bring them all onto the same key or keep each unit distinct, depending on how the building is managed. In East Hermosa and Hermosa Valley, we more often see owners who have just bought a place and want every lock reset before they settle in. Walk-street and alley-access homes near the beach may have a side gate and a street-facing door that are keyed differently, and owners often want them combined.
Garage and side-gate locks along the Hermosa Valley Greenbelt are another common request, since those are used often and tend to be the ones people forget when they change the main door. If a gate lock is corroded, we may recommend gate lock repair instead of a rekey.
Everything in town falls under ZIP code 90254, and we cover all of it, from North Hermosa and South Hermosa to Pier Plaza and the downtown blocks. Our storefront is at 10740 Wilshire Blvd in Westwood, about 19 miles from Hermosa Beach, and our mobile vans bring the tools and key-cutting equipment to you. You can see our Hermosa Beach service area for more on what we do locally.

Call (213) 577-1366What should you ask any locksmith before they start?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), known as an LCO license. Ask any locksmith for their license number before work begins, and confirm it with the state if you want certainty. You should also ask for the full job quote before work starts, who will actually be coming to your door, and whether the locks will be rekeyed or replaced.
If you are weighing a smart lock instead of a traditional keyed lock, our smart lock installation page covers what that involves. A rekey is for keeping a conventional key-operated lock and simply resetting who can open it.
Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps your existing lock and changes the internal pins so a new key fits. Changing locks removes the old hardware and installs new locks. Rekeying is usually the more economical route when the locks are still in good condition, while replacement makes sense for worn, corroded or low-grade hardware.
Can you rekey all the locks in my house to one key?
Yes, in most cases. We can rekey all house locks so a single key opens the front door, back door, garage entry and side gate. The exception is locks of different brands or keyways, which may need a different approach, and we check this when we see the hardware.
Should I rekey after buying a house in Hermosa Beach?
It is a smart move. You cannot know how many keys exist from past owners, tenants, agents or contractors. Rekeying the exterior doors, garage and gate locks before you move in means you control every key from day one.
How do I handle tenant turnover rekeying for my rental?
Call us after the tenant returns the keys, and we rekey each entry for the unit. Many landlords do this every turnover so the next tenant is the only one with access. We can rekey several units in one visit and label the keys for each.
Do you rekey locks that are rusty or salt-damaged?
We test them first. If the cylinder still turns smoothly, we can rekey it. If corrosion has seized the pins or the bolt, rekeying will not fix the problem and we will recommend replacing that lock instead. We tell you before any work begins.
Do you offer commercial rekey for restaurants and shops?
Yes. We handle commercial and business lock rekeying for front doors, back doors, storage rooms and offices, including after a staff change or a missing key. For panic hardware or storefront repairs, we handle those as separate services.
What if I lost my keys and can't get into my home?
Call (213) 577-1366 any time. We will help you get inside first, and then rekey the locks so the lost keys are useless. If you are standing at the door right now, tell us when you call so we can plan the work properly.
Do I need to be home during the rekey?
Someone authorized should be present, or we should have clear instructions from you before we start. We need access to each lock being rekeyed, and we test every lock with the new key before we leave. Property managers can arrange access with us in advance.
Will my old keys still work after a rekey?
No. Once a lock is rekeyed, the old key will no longer turn it. We test this at the door so you can see it for yourself. Only the new keys we give you, and any copies cut from them, will operate the lock.
