Should you rekey or replace your locks?
Most people who call us about a lock change are really asking one question: do I need new hardware, or just new keys? The honest answer is that it depends on what is on your door today. A lock change simply means that the keys that used to work no longer do. There are two ways to get there, and which one fits depends on the condition of the lock, what you want from it, and how much you care about how it looks.
Rekeying keeps your existing lock body and changes the internal pin arrangement so a new key works and the old keys do not. It is usually the more economical route when the hardware is sound. Replacing means taking the old lock off and installing a different one. That makes sense when the lock is worn, loose, mismatched across your doors, or when you want a feature the old lock never had.
You don't have to decide before you call. We look at the doors, tell you what we see, and lay out both paths. If rekeying is enough, we say so, even though it is the smaller job.
Why change locks after buying a house or moving in?
When you buy a home or move into a rental, you have no way of knowing how many copies of the keys exist. The previous owner, their relatives, a former tenant, a cleaner, a contractor, a real estate lockbox visitor: any of them may still have a key in a drawer. Most of those people are harmless. The point is that you can't verify it, and changing the locks is the only way to reset the question.
That is why a locksmith for a new house is one of the first calls we get after closing, and why a locksmith after moving is common even in rentals. In a rental, your lease and your landlord's rules come first, so confirm what you are allowed to change. If you are the property owner or manager, a lock change between occupants is routine practice.
A lock change also fits these situations:
- You bought a house and received a few keys, with no idea who else holds copies.
- You moved out of a shared household or ended a relationship and need the keys reset.
- A key was lost or stolen, and you don't want to wait to find out whether it matters.
- A contractor, house sitter, or short-term guest had access and the job is finished.
- The deadbolt sticks, the key turns roughly, or the lock was never fully reliable in the first place.

Call (213) 577-1366How does a lock change visit work?
We keep the process simple and explain each step as we go, so you are never guessing what you are paying for.
- You call (213) 577-1366 at any hour. We ask what kind of doors you have, how many, and whether this is a new home, a move-in, or a lost key.
- We come to you with a mobile van stocked for common residential hardware. In North Hollywood we are coming from our Westwood storefront, about 14 miles away.
- We confirm who we are working for. Before opening or changing anything, we ask for reasonable proof that you live at the property or have authority over it.
- We inspect every exterior door lock: knobs, deadbolts, handlesets, and any secondary locks like a side gate or patio slider. We check how worn each one is and whether it closes and latches cleanly.
- We walk you through rekey versus replace for each door and give you the cost picture before work begins. You choose.
- We do the work. For rekeys, we reset the lock cylinders to a new key. For replacements, we install the new hardware and check the strike plate and fit.
- We test each lock with the new keys, with the door open and closed, and show you how to use anything unfamiliar.
- We hand over the keys. If you need extra copies, we can cut them on the spot.
Rekey, replace, or upgrade: how do you decide?
Here is the way we usually think it through with a homeowner standing at the door.
Rekeying makes the most sense when the locks are in good mechanical shape and you are fine with how they look and feel. It also helps when you want every door on one key, which is something many new homeowners want after collecting a keyring of unmatched keys. You keep the hardware you have, and old keys stop working. If you want more detail on that option, our lock rekey service page covers it directly.
Replacement is the better call when something is wrong with the lock itself. Worn latches, loose handles, a cylinder that sticks, hardware that is corroded or visibly cheap, or a door with a missing deadbolt all point that direction. See lock replacement in North Hollywood for how that side of the work goes.
Upgrading is a third path. Some people use a lock change as the moment to add a deadbolt, move up to a stronger grade of hardware, or go keyless. If a front door has only a knob lock and nothing else, adding a deadbolt is often worth doing at the same visit. If you want keypad or app-based entry, we can tell you about smart lock installation and which doors suit it.
- Rekey if the hardware is sound, you want matching keys, and you are not changing the look of your doors.
- Replace if the lock is worn, damaged, loose, mismatched, or missing a deadbolt that should be there.
- Upgrade if you want stronger hardware or keypad entry, and you are already paying for a visit.

Call (213) 577-1366What affects the cost of changing locks?
We don't quote numbers on a web page, because the real cost depends on your actual doors. What we can do is tell you what moves the total up or down, so nothing at the door surprises you.
The biggest factor is whether you rekey or replace. Rekeying reuses your hardware, so you pay mostly for labor and the new key set. Replacement adds the cost of the new locks, which varies widely with the brand, grade, and finish you pick.
Beyond that, these things matter:
- How many locks need changing. A single front door is a different job from a house with a front door, back door, garage entry, and side gate.
- The condition of the doors. A lock that doesn't line up because the door has shifted may need a strike plate adjustment or other fitting work.
- Lock type. Standard knobs and deadbolts are simpler than multipoint systems, mortise locks, or older hardware that is hard to source.
- Key requirements. Matching every door to a single key, or adding restricted keys, takes more setup.
- Time of day. Late-night and holiday calls involve a technician out of normal hours, and we will tell you how that affects the visit.
- Add-ons. A new deadbolt, a keypad, or extra key copies are separate line items you can say yes or no to.
What does changing locks look like in North Hollywood?
North Hollywood is a majority-renter neighborhood, and that shapes most of the lock-change calls we think about here. Across ZIP codes 91601, 91602, 91605, and 91606, you find 1920s-to-40s bungalows on interior streets, a large postwar apartment stock, and newer mid-rise buildings near the North Hollywood Metro station.
In bungalow areas like Toluca Woods and West Toluca Lake, the usual story is a new owner with an older house. Original hardware may be decades old, with a front door lock, a back door that was changed at some point, and a kitchen door nobody remembers keying. A lock change there often turns into a full walk-around so every exterior door ends up on the same key, with worn hardware replaced and sound hardware rekeyed.
In the NoHo Arts District, the newer mid-rise buildings bring a different kind of call. A tenant who has been locked out of an apartment, or whose key went missing, sometimes needs the unit lock changed afterward. If that is where you are starting, our apartment lockout service handles the entry, and we can change the lock in the same visit if the building allows it. In a rental, check with your landlord or property manager first, because many buildings control which lock hardware can be used.
Older multifamily buildings in the Valley Plaza area and elsewhere often have shared entry doors and aging mailbox banks. A unit lock change does not fix those shared points, so if your old key might still open the front entry or the mailbox, it is worth asking about mailbox lock replacement too. Property owners handling tenant turnover in these buildings can read about our work with landlords.

Call (213) 577-1366Does North Hollywood's heat matter when you change locks?
North Hollywood sits in the flat interior of the valley, with hot, dry summers. The main seasonal effect on exterior doors here is expansion from heat. Wood doors and frames can swell and shift, and a lock that lined up fine in spring may bind in late summer.
That matters at lock-change time. If a deadbolt has trouble throwing into the strike plate, new hardware won't solve the problem on its own. When we change a lock, we check whether the door is dragging or the bolt is rubbing, and we adjust the fit when we can. We'd rather tell you the door needs attention than leave you with a new lock that sticks every August.
Why call Wilshire Lock & Key?
We have been in business since 1987. That is a long time to keep the same name on a storefront, and ours is at 10740 Wilshire Blvd in Westwood. We also run mobile service vans, so most lock changes happen at your door, not ours.
When you call (213) 577-1366, the phone is answered 24 hours a day, 7 days a week, year-round. You are calling one company. We don't pass your job to a dispatch middleman who shops it around, which means the person who understood your situation on the phone is the same company that shows up.
David, the owner and lead technician, oversees the work. If a job is unusual, the standard for how it gets done comes from him. We serve 140 cities across Los Angeles and Ventura counties, and North Hollywood is one of the places we know how to get to.
We also try to be straightforward about what you need. If a rekey will do the job, we won't push new hardware. If your locks are worn out, we'll say that plainly and show you why.
How can you check any locksmith before they work on your door?
Changing your locks means giving someone access to the security of your home, so it is fair to vet who you hire. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. Ask any locksmith for that license number before work starts. That includes us.
A few other signs are worth watching. A reputable company gives you the cost picture before work starts, tells you what it will do, and asks you to show you live at the address. Be careful with anyone who won't give a company name, quotes something very different once they arrive, or immediately wants to drill and replace a lock that could simply be rekeyed.
If you also need extra keys after the change, ask whether copies can be cut at the same visit. Our key duplication page explains what to expect.
Frequently asked questions
What is the difference between changing locks and rekeying?
Changing locks is the goal: old keys stop working. Rekeying is one way to get there, by resetting the inside of your existing lock for a new key. Replacing the lock is the other way. We'll tell you which one fits each door after looking at the hardware.
Should I change the locks right after buying a house in North Hollywood?
Yes, it is a good idea to do it soon after closing. You can't know how many keys the previous owner, agents, or contractors held. Older bungalows may also have mismatched hardware on different doors, which a lock change can tidy up so you carry one key.
Can you change locks at night or on a weekend?
Yes. Our phone is answered 24 hours a day, 7 days a week, all year, at (213) 577-1366. Out-of-hours calls can affect the cost, and we'll explain how before we start work.
I rent my apartment. Can I change the locks myself?
That depends on your lease and your landlord or property manager. Many buildings control the hardware on unit doors and the shared entries. Check first. If you get permission, we can do the work. Owners and managers can look at our landlord page for turnover situations.
Do I need to change every lock on my house?
Usually every exterior door that opens with a key should be included: front, back, garage entry, side doors, and any gate or patio lock. We can walk through them and rekey them all to one key so you don't carry a ring of mismatched keys.
How much will it cost to change my locks?
It depends on whether you rekey or replace, how many locks are involved, the lock grade and type, the condition of the doors, and the time of day. We explain the cost picture at your door before any work starts, so you decide with the details in front of you.
Will a new lock stick when it gets hot outside?
North Hollywood summers are hot and dry, and heat can make doors and frames expand. If a door is already tight, a new lock can bind too. We check the fit of the door and strike plate while we are there and adjust what we can.
Can you add a deadbolt or a smart lock while you are changing locks?
Yes. Many people add a deadbolt or go keypad during a lock change, since we are already on site. Tell us what you want when you call, and we'll confirm what suits each door before we begin.
