What does car key replacement actually involve?
A car key today is often two jobs in one. The first is the physical cut: the blade has to match the lock cylinders in your doors and ignition. The second, depending on the vehicle, is electronic: the car may need to recognize the key before it will start, or a remote may need to be paired so the buttons work. Some vehicles need both, some need only a cut, and a few older ones need only a simple copy.
That is why we don't quote a replacement over the phone as though every key were the same. The year, make, model and trim decide what kind of key your car uses and how it gets set up. We confirm that by VIN and by looking at the vehicle in person, rather than guessing from a general chart.
This page covers replacing and adding keys: a spare when you still have one working key, and a new key when you have none. If your situation is narrower, we have pages for lost car key replacement, key fob replacement and transponder key programming. The service is the same family of work, but each page goes deeper on its own piece.
Lost your only key, or just want a spare car key?
These are two very different starting points, and they change how the job goes.
If you still have a working key, making a duplicate car key is usually the simpler and more economical route. The existing key gives us something to work from, and the car already knows how to talk to a key. Adding a spare while you can still start the car is the best time to do it, and it is far less stressful than doing it after the only key goes missing.
If you have no key at all, we have to create one from the car itself. We identify the vehicle by VIN, confirm you are the owner, cut a blade to the lock code or by working from the lock, and then program the new key to the car. It takes more steps and more equipment, which is why a no-key situation generally costs more than a copy. It is still very doable at the curb in most cases.
- Spare car key: you have one working key and want a second, so you are never stranded.
- Replacement car key: the key was lost, stolen, snapped or stopped working, and you need a new one.
- Cutting only: some older vehicles take a plain mechanical key with no electronics, which we can cut without programming.
- Cut and program: most newer keys need the blade cut and the key introduced to the car.

Call (213) 577-1366How does mobile car key replacement work in Sun Valley?
Our vans carry key-cutting and programming equipment, so the work happens where your car is parked. That might be your driveway, an apartment lot, a work yard or a street curb. Nothing about the process requires towing the car to a shop. If you want to know more about our van service in general, see our mobile locksmith page.
Here is how a typical visit goes:
- You call (213) 577-1366 and tell us the year, make, model and where the car is. We answer 24 hours a day, 7 days a week.
- We ask whether you have any working key, and whether the car is currently locked, running or unable to start, so we bring the right equipment.
- On arrival we verify ownership. We will ask for a photo ID and proof the vehicle is yours, such as registration or title. We do this on every job, and it protects you.
- We confirm the VIN and the key type for your exact vehicle, and we explain what the job involves and what affects the final cost before we start.
- We cut the new key, then program it to the vehicle and pair any remote functions that apply.
- We test everything with you: turning the lock, starting the car, and checking buttons or remote functions. Then we go over what to do with any old or lost keys.
What affects the cost of a replacement car key?
We don't post flat numbers because the honest answer is that the same request can be very different jobs. Here is what moves the cost up or down, so you can understand any quote you receive from us or anyone else.
Ask every locksmith to explain these factors. A company that can't tell you why a quote is what it is should make you cautious.
- Key type: a simple mechanical key, a key with an electronic chip, a remote head key and a push-button smart key are very different in parts and setup.
- Whether you have a working key: copying from a working key is usually the lighter-cost route compared with creating a key when none exists.
- Vehicle make, model and year: some manufacturers make programming straightforward, others lock it down with extra security steps.
- Number of keys: adding a second key during the same visit is generally more economical than calling us back later.
- Remote and fob functions: pairing buttons for locks, trunk or alarm adds to the work.
- Time and place: a middle-of-the-night call or a location far from our base involves more effort than a daytime appointment nearby.
- Dealer involvement: if a vehicle needs something only the dealer can supply, that changes the plan and the total, and we will say so up front.

Call (213) 577-1366Can you do same day car key replacement?
In most cases, yes. We answer the phone around the clock and send a van to you, and the large majority of cars can be handled start to finish in a single visit. That is what same day car key replacement means for us: you call, we come to the vehicle, and you drive away with a working key. We won't promise an arrival window over the phone, because traffic and our current calls vary, but we will tell you honestly what to expect when you call.
There are exceptions, and we would rather tell you now than surprise you at the curb. Some makes and model years are dealer-only for certain keys, or need a code or part that only the dealer can supply. Some vehicles also require a key blank that has to be ordered. If your car falls in one of those groups, we say so as soon as we have the VIN and have looked at the vehicle, and we explain your options. We do not sell you a visit that can't end in a working key.
If your car is locked with the key inside, or you can't get in at all, that is a separate first step, and our car lockout page explains how we handle it.
Where in Sun Valley do car key calls come from?
Sun Valley is spread out, and cars here get used hard. People commute from 91352 along Roscoe Boulevard, run errands on Glenoaks Boulevard and Sunland Boulevard, and work on or near the San Fernando Road industrial corridor. A lost or broken key can happen anywhere along those routes, and we come to wherever the car is sitting.
One scenario we are familiar with is car key replacement near the Sun Valley Metrolink Station. Someone leaves a car in the lot or on a nearby street, comes back later, and the key is gone or stops working. Because we come to the vehicle and do the cutting and programming there, you don't have to arrange a tow or a ride across the Valley. Our storefront is in Westwood, about 17 miles from Sun Valley, and our vans do the traveling.
Apartment residents along the Glenoaks Boulevard corridor often have a different problem: a single key and shared or street parking. We recommend a spare before you need one. In Stonehurst, where many homes are older cottages with narrow driveways and street parking, we can work at the curb as easily as in a driveway. Work vehicles around San Fernando Road are another common case, where a business owner needs a key replacement without losing a day of work.
The eastern San Fernando Valley is hot and dry, and Santa Ana winds carry dust that works into exterior lock cylinders. A door lock on an older car that sticks or grinds can wear a key down over the years, and a worn key is often what finally gives up. If your key already turns hard, bring it up when you call. A fresh key cut to the vehicle often feels very different.

Call (213) 577-1366What if the problem is the ignition, not the key?
Sometimes a key that won't turn or won't start the car isn't the key's fault. A worn ignition cylinder can chew up keys, and a new key in a worn ignition may fail quickly. If we see signs of that, we say so honestly and tell you whether a new key will solve the problem on its own.
When the ignition itself is the issue, that is a repair job rather than a key job, and our ignition repair page explains how we handle it. We won't cut you a new key and send you away if we can see the original problem will return. For the full range of vehicle work, our automotive locksmith page gives the bigger picture.
Why call Wilshire Lock & Key for your car key?
We have been in business since 1987, and our owner and lead technician, David, oversees the work. We are one company, not a call-center dispatcher passing your job to whoever is available. When you call (213) 577-1366, you are reaching the same business that sends the van.
We have a real storefront at 10740 Wilshire Blvd in Westwood, along with mobile service vans. You can look us up and see that we exist at a physical address, which matters when you are handing over a car key.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work on your vehicle. That is a good habit regardless of who you call. A reputable company will give you the answer without hesitation.
We serve 140 cities across Los Angeles and Ventura counties, and Sun Valley is one of them. We explain the work and the cost factors before we begin, we tell you when a job is dealer-only, and we verify ownership every time. That last step can feel like an inconvenience at the curb, but it is how a key stays in the right hands.
What to have ready before you call
A few details help us tell you what your car needs and what to expect. None of them are required to call us, and we can help you find the rest on the spot.
If you can't find some of this, don't worry. Call anyway and we will work through it with you. You can also reach us through our contact page if you prefer to write first.
- Year, make, model and trim of the vehicle.
- The VIN, usually visible through the windshield on the driver's side of the dashboard, or on your registration or insurance card.
- Where the car is parked and whether it is locked, running or won't start.
- Whether you have any working key, and whether the old key had remote buttons.
- Photo ID and proof of ownership, such as registration or title, ready for when we arrive.
- How many keys you want. Adding a spare during the same visit usually makes sense.
Frequently asked questions
Can you replace a car key if I've lost every key?
Usually yes. We identify the car by VIN, confirm you own it, then cut and program a new key at the vehicle. It involves more steps than copying an existing key. Some makes and models are dealer-only for certain keys, and we tell you that plainly once we've confirmed the VIN.
Is it cheaper to make a spare before I lose my key?
Generally, yes. Duplicating from a working key is usually the more economical route than creating a key when none exists. Doing it before you're stranded also saves a stressful call. We can't quote numbers here, because cost depends on your specific vehicle, but we'll explain the factors.
Do I need to tow my car to you?
In most cases no. Our vans carry cutting and programming equipment, so we work where your car is parked in Sun Valley. If a particular vehicle needs dealer-only parts or codes, we tell you what that means for your options.
Can you cut and program a key the same day I call?
For most vehicles, yes. We answer 24 hours a day, every day, and the large majority of jobs finish in one visit. Some makes and years need a part ordered or dealer involvement, and we confirm that by VIN and in person rather than promising what we can't deliver.
What proof of ownership do you need?
We ask for a photo ID and proof the vehicle is yours, such as registration or title. We do this on every job. It protects you, because it keeps a key to your car from going to someone else.
Will the new key work exactly like my old one?
That's the goal. If your old key had remote buttons, we pair the new one so those functions work, and we test everything with you before we leave. How the buttons are set up depends on the vehicle, and we explain what applies to yours.
Can you replace a key that broke off in the lock or ignition?
That is a related but separate job: the broken piece has to come out first. We have a page on broken key extraction for that. Once the piece is out, we can cut and program a new key as part of the same visit if needed.
Should I ask a locksmith for a license before they work on my car?
Yes. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work begins. A reputable company will answer directly. It's a sensible habit for any service involving your vehicle.
How do I get a quote for car key replacement in 91352?
Call (213) 577-1366 with your vehicle's year, make, model and VIN if you have it. We'll explain what type of key it uses, what affects the cost, and whether the job is one we can finish on site or needs the dealer.
