What is lock rekeying, and what does it actually change?
Rekeying changes the inside of a lock so that a different key operates it. Most residential locks use small spring-loaded pins of varying lengths. The key lifts each pin to exactly the right height, and the cylinder turns. To rekey, we take the cylinder apart, swap the pins for a new combination, and put it back together. The lock stays on your door, the handle and finish stay the same, and the old key simply stops working. A new key cut to the new combination takes its place.
This is why a house rekey is such a practical fix. If you want every key that has ever been handed out to stop working, you do not need new hardware. You need new pins. When you ask us to rekey all house locks, we can usually set the front door, back door, side gate door and any deadbolts to one key, so you carry one key instead of a ring of them. Locks from different manufacturers use different keyways, so occasionally one lock in a mixed set has to have its cylinder swapped to join the group. We will tell you at the door if that applies.
It also helps to know what rekeying does not do. It does not repair a worn lock, tighten a loose handle, or raise the security level of cheap hardware. If the lock itself is failing, rekeying it is effort in the wrong place. We check that before we start, and we say so plainly if the better move is a different lock.
When should you rekey your locks?
The rule is simple: rekey whenever you cannot say with confidence who holds a working key. Keys get copied, loaned, and forgotten about, and none of that shows up on the lock. These are the situations where we get called most often for a lock rekey:
- After moving in. Previous owners, tenants, relatives, cleaners and contractors may all still have keys. Rekey locks after moving and you start from a clean slate.
- After buying a house. Rekey locks after buying a house, ideally before you move your belongings in. You have no way of knowing how many copies of the old keys exist.
- After a tenant moves out. For a landlord, tenant turnover rekey is routine maintenance. It is the standard way to make sure the departing tenant's keys, and any copies, are useless.
- After losing keys. If a key was lost somewhere with your address attached, or stolen along with a wallet or bag, rekey locks after losing keys rather than hoping it stays lost.
- After a change in who lives there. A roommate leaving, a relationship ending, or a caregiver or employee no longer working for you are all good reasons.
- After a break-in where keys were taken, or when you simply want every lock on the property to match one key.

Call (213) 577-1366What if you only misplaced a key at home?
Not every missing key means a rekey. If you lost a spare in your own house and it turns up in a coat pocket a week later, there is no reason to change anything. Where the key left your control, the picture is different. A key lost on a hike, at a gym, or in a taxi is a key a stranger could pick up. If it has nothing identifying on it, the risk is lower, but you are the one who decides how much risk you want to carry. We are happy to talk it through on the phone, and we will not push you to rekey when it is not needed.
How does a rekey visit work, step by step?
We keep the process the same for every customer, because it is the process that works. Here is what to expect when you call (213) 577-1366 at any hour.
- You call and tell us what you have: how many locks, whether they are knobs, levers, deadbolts or padlocks, and what prompted the rekey. A few details on the phone let us bring the right pinning kits and spare parts.
- We come to you in a mobile van, or, for a lock you can remove such as a padlock or a detached cylinder, you can bring it to our Westwood storefront at 10740 Wilshire Blvd.
- We confirm you are entitled to have the locks changed. That usually means ID that matches the address, a lease, or authorization from the owner or property manager. It is a safeguard for everyone, and any reputable locksmith will ask.
- We inspect each lock before opening it. We check that it turns smoothly, that the latch lines up with the strike plate, and that the hardware is worth keeping.
- We rekey each cylinder to the new combination, then test the new key repeatedly in each lock and confirm the old key no longer turns it.
- We hand over the new keys, and if you want extra copies cut, we do that on the spot. We also tell you about anything we noticed, such as a worn deadbolt or a door that rubs.
Should you rekey or replace the locks?
Rekeying is usually the more economical route when the hardware is sound. You keep the locks you already chose, the doors stay as they are, and nothing needs refitting. That is the right call for most homes after a move or a purchase.
Replacement makes sense in other cases. If a lock is worn, sticks, has a loose or damaged body, or has been forced, new hardware is the better investment. The same goes if you want a different finish, a different style across the house, or a higher level of resistance to picking and drilling. Our pages on changing locks and lock replacement cover those jobs in detail, and if your goal is stronger protection rather than just new keys, read about high-security locks.
Sometimes the answer is both: rekey the solid locks and replace the one weak lock on the back door. We would rather give you that mixed answer than sell you a full set you do not need.

Call (213) 577-1366What affects the cost of lock rekeying in Valley Glen?
We do not quote numbers on a web page, because the real figure depends on your doors. We can explain what moves it up or down, so the quote you get on the phone makes sense.
- Number of cylinders. Rekeying is done lock by lock, so a front door and one deadbolt is a smaller job than a whole house with a garage entry, a side door and a gate lock.
- Brand and keyway. Some locks rekey easily and others need specific parts or are built so they cannot be rekeyed in the usual way.
- Condition of the lock. A clean, smooth cylinder goes quickly. A corroded or damaged one takes more care, and sometimes replacement is the better choice.
- Number of keys. Cutting extra copies adds to the job, as does matching keys across several locks.
- Where the work happens. Bringing a removable lock to our storefront is different from a van visit. Distance matters too; Valley Glen is about 13 miles from our Westwood base.
- Time of day. Our line is open 24 hours a day, and after-hours calls can be priced differently from a daytime appointment.
- Commercial complexity. Offices and shops that need a master key setup or several different key levels take more planning than a house.
How we handle pricing conversations
Once we know the number and type of locks, we give you a clear figure before we start working. If something we find at the door changes the picture, such as a lock that cannot be rekeyed, we stop and explain before going further. Compared with replacing every lock, rekeying is usually the lighter-cost option, but we would rather confirm that for your specific doors than promise it in advance.
Rekeying in Valley Glen: postwar tract homes, student rentals and apartment corridors
Valley Glen sits on the central valley floor, and most of its housing is postwar single-family tracts from the 1940s and 1950s. The neighborhood was carved out of Van Nuys and North Hollywood in the late 1990s, so the housing and hardware here look like those older postwar areas. In practice, that makes a home purchase one of the most common reasons people here call us for a rekey. A house that has been through several owners over decades can have locks of mixed ages and brands, and nobody knows how many keys are out there. We look at each lock, rekey the ones that are sound, and flag the ones that are tired. If you are buying in 91401, 91405 or 91606, ask us to rekey before your moving day, not after.
Around the Los Angeles Valley College district, the pattern is different. Student rentals change hands often, with roommates leaving and others joining. That is the textbook case for a tenant turnover rekey: one visit, one set of new keys, and the previous occupants' copies stop working. If you are a student or a roommate and the lease holder has agreed, we can work with that. If you are a landlord, our page for landlords explains how we handle repeat turnover work.
Along the Victory Boulevard corridor, apartment buildings are concentrated, and rekeying there often means unit doors, shared entries and mailbox areas, with the manager or owner authorizing the work. The Burbank Boulevard and Oxnard Street corridors and the Fulton Avenue area mix homes and small businesses, so a call from one of those streets might be a house rekey in the morning and a shop door in the afternoon.
The heat matters too. Valley Glen has hot, dry summers, and heat-driven expansion of doors and weatherstripping is the main seasonal issue. A door that suddenly sticks in August is often a fit problem, not a cylinder problem. We check alignment while we are there, so you do not pay to rekey a lock that was never the culprit.
Properties backing the Tujunga Wash Greenway corridor often have gates and padlocks along the rear. Some padlocks can be rekeyed, and some cannot, depending on how they are built. We check what you have and tell you honestly which route works.

Call (213) 577-1366Apartment, landlord and commercial rekeys
An apartment lock rekey follows the same process as a house, with a few extra considerations. We need clear authorization from the owner or manager. We often work through several units in a row, matching each unit to its own key, and sometimes tying the shared entries into the right access plan. If a tenant has been locked out of a unit while this is going on, our apartment lockout page explains that separate service.
Commercial rekey and business lock rekey work is a bit different. The problem might be an ex-employee who still has a key, a lease change, or an owner who wants every door to match one key for the staff and a different one for the back office. We can rekey office, shop and storage doors, and for larger layouts we plan the key structure with you first. Our commercial locksmith page covers the broader scope of business work. A commercial lock rekey may also reveal that a door closer or a panic bar needs attention, and we flag that when we see it rather than leaving it for later.

What to have ready when you call
A little preparation makes the visit smoother. Know how many exterior doors you have, and count deadbolts and knobs separately. Tell us whether the locks are the same brand if you know. Have ID ready that matches the address, or the lease or owner authorization if you are a tenant or manager. Decide how many copies of the new key you need, so we can cut them during the visit instead of coming back. If you have the old keys, gather them; they help us confirm which locks are working normally.
Frequently asked questions
Is rekeying cheaper than replacing my locks in Valley Glen?
Usually, yes. When the hardware is in good shape, rekeying is the lighter-cost option because you keep the lock and only change the pins and the key. If the lock is worn or damaged, replacement can be the smarter spend. We confirm which applies when we hear the details of your doors.
Should I rekey locks after buying a house?
We recommend it. You do not know how many keys the previous owners, agents, tenants or contractors made. Rekeying before you move in means only the keys you hold will work. It is one of the most common calls we get for postwar homes in the neighborhood.
Can you rekey locks if I do not have a working key?
Often yes, as long as the lock is still operable and we can verify you are entitled to change it. If you are locked out as well, we deal with getting you inside first, then handle the rekey. Our house lockout service is separate from the rekey itself.
Can you make all my doors work with one key?
In most cases we can rekey the front door, back door and deadbolts to one key. Locks from different manufacturers use different keyways, so one or two might need a cylinder swap to join the set. We tell you which at the door.
Do you rekey apartments between tenants?
Yes. A tenant turnover rekey is routine for us. We need authorization from the owner or manager, and we can work through several units on one visit, keeping each unit's keys separate.
Can you rekey a smart lock or a padlock?
It depends on the model. Many smart locks have a standard mechanical cylinder that can be rekeyed, though the electronic codes are reset separately. Some padlocks can be rekeyed and others cannot. Tell us the make on the phone and we will say what is possible.
Do you handle commercial lock rekey for businesses?
Yes. We rekey office, shop and storage doors, and we can plan a key structure where different people need different access. If you want a full master key layout, we talk through that before any work begins.
Can I call at night or on a weekend for a rekey?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round. After-hours work can affect the quote, and we tell you that before we start.
Do you serve all of Valley Glen, including 91401, 91405 and 91606?
Yes. We come to homes, apartments and businesses throughout Valley Glen with our mobile vans, from the Valley College area to the Victory Boulevard and Burbank Boulevard corridors. Our storefront is in Westwood, about 13 miles away, and you are welcome to bring removable locks there.
