What does a lock rekey actually do?
A lock rekey changes the internal pin arrangement of a lock cylinder so that a new key operates it and the old keys no longer do. The lock stays on the door. The deadbolt, the knob, the handle set all remain in place. What changes is the part you never see: the small pins inside the cylinder that read the cuts on your key.
For most La Verne homeowners and renters, rekeying answers one simple question: who else has a key to my place? It might be the previous owner, a tenant who moved out, a roommate who left, a contractor, a house sitter, or a key ring you can no longer find. You do not need to know who has a copy. You only need those copies to stop working.
Because the hardware stays, a house rekey is usually the more economical route compared with swapping every lock, as long as the existing locks are in decent shape. When they are not, we will tell you that plainly instead of rekeying something that should be replaced.
When should you rekey your locks?
Rekeying makes sense any time the number of people holding keys is uncertain. These are the situations we hear about most often from people calling about a home lock rekey:
- Rekey locks after moving: you are the new occupant and have no idea how many keys the last household handed out, to whom, or how long ago.
- Rekey locks after buying a house: the seller, the agent, inspectors, and past contractors may all have held keys at some point. Rekeying at closing gives you a clean starting point.
- Rekey locks after a tenant moves out: a tenant turnover rekey means the departing tenant's keys, and any copies they made, become useless without replacing perfectly good hardware.
- Rekey locks after losing keys: if the lost key had an address attached, or you simply cannot say where it went, rekeying removes the worry.
- After a roommate, partner, cleaner, or contractor no longer needs access: the person may be perfectly honest, but a key that still works is a loose end.
- Rekey all house locks to one key: if your front door, back door, and garage entry each take a different key, we can match them so one key runs everything.
How does a rekey service work, step by step?
Here is how a typical visit goes. The details shift a little with the lock brand and condition, but the order stays the same.
- You call (213) 577-1366. We ask how many locks need rekeying, which doors they are on, the brand if you know it, whether you want them keyed alike, and where in La Verne you are.
- A mobile technician comes to you in one of our vans. We do not ask you to bring locks to a counter, though our storefront at 10740 Wilshire Blvd in Westwood is there if you would rather deal with us in person.
- We look at each lock before touching it. We turn the key, work the latch, check how the door sits in the frame, and look for worn or damaged cylinders. Any problem gets explained before we start.
- We remove each cylinder, take out the old pins, and set new ones to match a new key. Then we reassemble it and put it back on the door.
- We cut the new keys and test every lock with every key. We also try an old key in each lock to confirm it no longer works.
- We hand over the keys and talk through next steps: how many spares you want, who should get them, and whether any lock on the property should be handled differently.

Call (213) 577-1366How much does lock rekeying cost in La Verne?
We will not quote a number on a web page, because the honest answer depends on your doors. What we can do is tell you exactly what moves the price, so nothing surprises you on the phone.
Whatever applies to your situation, we go over it with you and give you the figure before we start work, not after.
- The number of cylinders. Rekeying one back door is a smaller job than rekeying every entry on a large house.
- The type of lock. Standard residential cylinders are straightforward. High-security or restricted-keyway cylinders involve different parts and procedures.
- Keyed alike or separate. Matching several locks to one key is common and usually simple, but it does shape the work.
- Condition of the hardware. A worn or damaged cylinder may need a replacement part, and that changes the scope.
- How many keys you want cut. A pair of keys and a full set for a household are different amounts of work.
- Time of day. We answer the phone around the clock, and after-hours calls are handled differently than a scheduled daytime visit.
- Travel. La Verne is about 42 miles from our Westwood base, and our mobile vans travel to you, so distance is a real part of the quote.
- Residential or commercial. Business rekeys often involve more doors, different hardware, and sometimes a key system.
Tenant turnover rekey: what landlords and renters should know
Rekeying between tenants is routine work, and for good reason. The lock is fine, the door is fine, and the only problem is that a former occupant may still have working keys. Rekeying fixes exactly that and nothing more. If you manage rental properties, our page for locksmiths who work with landlords covers how we handle multiple units and repeat turnovers.
If you are a tenant and want an apartment lock rekey, talk to your landlord or property manager first. Changing the lock on a rental without permission can cause problems with your lease, and a good property manager will often want to arrange the rekey themselves. If you have lost your key and the landlord approves, a rekey is the clean fix.
One practical tip for landlords: decide in advance how many keys each unit gets and keep a simple log. When a tenant leaves, you rekey, cut the set you need, and the old set becomes scrap. If you need extra copies later, key duplication is a separate, quick service.
Can you rekey a business or commercial lock?
Yes. A business lock rekey follows the same principle as a house, but the situations differ. A staff member leaves, a lease changes hands, a manager loses a ring of keys, or a shop simply wants to know that only current employees can open the back door. In each case, rekeying the affected cylinders is usually a more measured response than replacing every door's hardware.
Commercial rekey work also tends to involve more variety: rim cylinders, mortise cylinders, padlocks, gate locks, and interior office doors. If you want different staff to open different doors while one key still works for management, that is a master key system rather than a simple rekey. Our commercial locksmith work covers the wider picture, and a master key system is the right conversation if you need layered access.
If your question is about one door and one key, we will say so and keep it simple.

Call (213) 577-1366What does rekeying look like around La Verne?
La Verne is one ZIP code, 91750, but the housing varies a lot from one part of town to the next, and that changes what a rekey involves.
Old Town La Verne, the historic Lordsburg area, still has craftsman bungalows and early-20th-century homes, particularly near the University of La Verne. Owners there often want to keep the original-looking knobs and handle sets. Rekeying fits well, since it leaves the visible hardware alone. Whether a particular older lock can be rekeyed, or whether the cylinder is too worn, is something we confirm in person at the door rather than promise over the phone.
The University of La Verne area is also where student rental turnover shows up. When one group of tenants leaves and another arrives, rekeying the front door and any back or side entries is the straightforward way to make sure last year's keys do not open this year's house.
Further north, La Verne Heights, Sierra La Verne, and the North La Verne foothills have newer and larger homes. More doors means more locks, and many owners there ask us to rekey all house locks so a single key opens everything. The Marshall Canyon area adds another consideration: hot inland summers and foothill wind. Heat can make doors swell, and a swollen door can make a lock feel stiff or bind when the real cause is the door itself. Dry, dusty Santa Ana conditions can also work into cylinders. While we rekey, we check how smoothly each lock turns and tell you if the problem is the lock or the door. Because La Verne is well inland, salt-air corrosion is not a concern here.
South La Verne, near the airport and Fairplex, has a notable share of mobile home communities. Locks on mobile homes are often a different situation: if the hardware is worn, replacement may make more sense than rekeying, and we will say so after looking at it. For commercial needs near Brackett Field Airport, hangar, office, and gate locks can be rekeyed too. That is where a business lock rekey and our approach to access come into play, and it is worth talking through the specific doors and gates before anyone arrives.
When is rekeying not the right answer?
Rekeying is not a cure-all, and a trustworthy locksmith should say so. We will recommend something else in these cases:
If the lock is broken, loose, or visibly damaged, a rekey will not fix it. You need a lock replacement instead. If the lock is old and you want better security, not just fresh keys, upgrading the hardware is usually smarter than rekeying a weak lock. If you are asking about swapping the hardware itself, our change locks page explains the difference.
And if you are locked out right now, that is a different job from rekeying. We handle house lockouts too, and sometimes we can rekey the same visit once you are back inside.
The test we use is simple: if the lock works well and the only problem is who holds keys, we rekey. If the lock itself is the problem, we say so.

Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps your existing lock and changes the pins inside so a new key works and old keys do not. Changing locks means removing the hardware and installing new locks. Rekeying is often the more economical route when the locks are in good shape. Replacement makes sense when the hardware is worn, damaged, or you want an upgrade.
Can you rekey all my house locks to the same key?
Usually yes. Matching front, back, and garage entry locks to one key is a common request. It depends on the brands and condition of each lock, and we confirm when we look at them. If one lock cannot be matched, we will tell you and offer options.
Should I rekey after buying a house in La Verne?
It is a smart step. You do not know how many keys the previous owner, agents, or contractors have. Rekeying makes those keys useless without replacing good hardware. Many buyers do it the first day they have possession.
Can you rekey locks if I lost my only key?
Yes. We can rekey a lock without the original key by removing the cylinder and setting it to a new key. If you are locked out as well, we can deal with that first. Either way, call (213) 577-1366 and tell us what you have.
Can older Old Town La Verne locks be rekeyed?
Often, yes, but it depends on the specific lock. Older cylinders can be worn or have parts that are hard to match. We look at the lock in person and tell you honestly whether rekeying is realistic or whether replacement or period-appropriate hardware would work better.
Do you handle tenant turnover rekeys for rentals?
Yes. Rekeying between tenants is routine. If you manage several units, we can plan the work so each property gets a fresh set of keys. Tenants should check with their landlord before requesting a rekey on a rental.
Do you do commercial and business lock rekeying?
Yes. We rekey office doors, shop entries, gates, and similar locks. If you need different staff to open different doors, that is a master key system, which is a separate conversation. For a single door, we can keep it to a simple rekey.
Can I rekey my own locks with a kit?
Some people do, and kits exist for certain residential locks. The risk is that a kit rekey can leave a lock sticky, or the old key can still partly work if the pins are set wrong. If you want it tested properly, we are glad to do it.
Will you come out at night or on weekends?
Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. When you call, we talk through what you need and what applies to your situation. After-hours calls are priced differently than scheduled visits, and we explain that on the phone.
