What does car key replacement in Winnetka actually involve?
Replacing a car key is really two jobs that have to agree with each other. The metal has to be cut so it turns the door locks and the ignition, and on most modern vehicles the electronics have to be programmed so the car accepts the key. A key that is cut perfectly but not programmed may open the door and still refuse to start the engine. A programmed key with a poorly cut blade may start the car but bind in the ignition.
At Wilshire Lock & Key we do both at your vehicle. Our mobile vans carry key-cutting and programming equipment, so a Winnetka driver doesn't have to arrange a tow or find a ride just to get a working key. We have been doing this kind of work since 1987, and the phone is answered around the clock at (213) 577-1366.
This page covers spare keys, duplicate car keys, and replacements when a key has been lost, snapped, or worn out. If every key to the vehicle is gone, our lost car key replacement page goes deeper on that situation. Here we explain the whole process of getting a new key made.
Which kind of car key do you have?
The first thing we ask on the phone is what your key looks like, because the answer changes the tools, the time on site, and the cost. Most keys fall into one of these groups:
Which group your vehicle falls into depends on its make, model, and year. We confirm that by VIN and by looking at the key and the car in person, not by guessing from a phone description. If you aren't sure what you have, give us the vehicle details and a description of the key head, and we'll sort it out together.
- A plain metal key with no electronics in the head. This is usually the simplest job: cutting only.
- A transponder key, with a plastic head holding a chip the car checks before it will start. It needs cutting and programming. We cover that in more detail under transponder key programming.
- A remote-head key, where the lock and unlock buttons are built into the key head. It adds remote pairing to the cutting and programming.
- A key fob or smart key for push-button start, which usually works differently from a blade key. See key fob replacement for how we approach those.
- A laser-cut or high-security key, with a milled channel in the blade rather than teeth along the edge. It needs different cutting machinery than a standard blade.

Call (213) 577-1366How does mobile car key replacement work, step by step?
Here is how a typical call goes from the first phone call to a key that starts your car.
- You call (213) 577-1366 and tell us the make, model, year, and where the vehicle is parked. If you can, have the VIN ready. It is usually visible at the base of the windshield on the driver's side and on the driver's door jamb.
- We ask what keys you have: none, one working key, a broken key, or a fob that works while the blade doesn't. That tells us whether we are copying a key or creating one from scratch.
- We confirm the key type and tell you, before anyone drives out, whether your vehicle is something we can complete on site or a dealer-only case.
- A van comes to the vehicle. Before we cut anything we ask for your ID and something that ties you to the car, such as the registration or title. We do this on every vehicle.
- We cut the blade, working from your existing key if you have one, or from the key information for your vehicle if you don't.
- We program the key to the car and pair any remote functions, if the key has them.
- We test everything before we call it finished: door locks, trunk, ignition, starting the engine, and each remote button. We go over the cost with you before the work starts, not after.
Can you do same day car key replacement?
Often, yes. Many calls are finished in a single visit because the van carries cutting and programming equipment, and that is what makes same day car key replacement realistic for a lot of vehicles. We won't promise it for every car, though. It depends on the key type, whether the right key blank is on the van or has to be sourced, and whether your vehicle is one we can complete outside a dealership. We tell you which situation you're in on the first call.
Because the work happens where your car is parked, car key cutting doesn't require you to drive anywhere in a vehicle you can't start. It follows the same idea as our mobile locksmith service, built around the vehicle instead of a building. Day or night, it is the same number: (213) 577-1366.
What if my car is a dealer-only case?
Not every vehicle can be finished by a locksmith, and we would rather say so than waste your time. Some makes, models, and years need equipment, codes, or authorization that only the dealer can access, and some need the car brought in for programming. We don't keep a blanket list to recite, and we won't pretend to. When we confirm your VIN, we tell you plainly if yours is one of those cases, so you can decide what to do next.
Sometimes the key isn't the real problem. If a key goes into the ignition but won't turn, a new key may not fix it, and the cylinder itself needs attention. That is the territory of ignition repair. If a key has snapped off in a door or ignition, the first job is broken key extraction, and then we make the new key.

Call (213) 577-1366What affects the cost of car key replacement?
We don't quote numbers on a web page because the honest answer depends on your vehicle. These are the things that move the cost up or down:
A quote that doesn't ask for your vehicle details is a guess. We would rather ask a few questions up front and then tell you the cost before we start cutting.
- The key type: a plain blade, a transponder key, a remote-head key, a smart key, or a laser-cut key all involve different parts and different work.
- The make, model, and year, which determine the programming method and the key blank.
- Whether you still have a working key. Copying from one is usually the more economical route compared with starting from nothing.
- How many keys you need made in one visit.
- Whether remote buttons or push-button start have to be paired.
- Where the vehicle is and what time of day you need service, since after-hours calls and travel are part of the job.
- Whether the vehicle turns out to be a dealer-only case, which changes what we can do.
Should you get a spare car key before you lose the only one?
If you still have one working key, this is the best moment to make a duplicate car key. Copying from a key you can hold is a simpler job than creating a key for a vehicle with no keys at all, and it is usually the lighter-cost option. When every key is lost, there are more steps: confirming ownership, working out the key information for the vehicle, cutting from that, and programming a key the car has never seen.
A spare car key also saves you from a bad day. Keep it somewhere safe at home, not in the vehicle or on the same ring as the key you carry. If more than one person drives the car, a second key keeps everyone from sharing one.
We cut and program spares at your vehicle, or you can call us to talk through what your key type involves before you decide.
Why call Wilshire Lock & Key for your car key?
Car keys are a small job with a lot of ways to go wrong, so who does the work matters. Here is what you get when you call us:
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith who comes to your car for their license number, whoever they are. For the wider picture of what we do on vehicles, see our automotive locksmith page. If you are locked out and the key is inside, that is a different job, covered under car lockout.
- We have been in business since 1987.
- We have a storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024 in Westwood, plus mobile service vans.
- You deal with one company, not a dispatch middleman who passes your call to whoever is available.
- David, the owner and lead technician, oversees the work.
- The phone is answered 24 hours a day, 7 days a week, year-round.

Call (213) 577-1366Car key replacement around Winnetka and ZIP 91306
Winnetka is about 20 miles from our Westwood storefront, which is exactly why the work is done by mobile van. We come to the car in 91306 instead of asking you to come to us. It might be parked on a tract-home block of 1950s stucco houses, in an apartment lot along the Sherman Way, Roscoe Boulevard, or Vanowen Street corridors, or near the Winnetka Avenue corridor by Pierce College. Wherever the vehicle is, that's where we do the cutting and programming.
The apartment stretches along Sherman Way and Roscoe Boulevard are a common place for lockout calls, and a missing key ring often takes the house key and the car key together. If that happens, tell us on the phone and we can plan the visit around both problems. If you lost a key near the Winnetka Recreation Center at Roscoe Boulevard and Winnetka Avenue, Runnymede Park, or Quimby Park, retracing your steps before you call is worth a few minutes of your time. If it doesn't turn up, we can make a replacement.
If you run a small shop on the Saticoy Street or Vanowen Street commercial strips and need a spare key for a work vehicle, the same process applies. Hot, dry Valley summers mostly affect wood doors and frames, not car keys, so heat is rarely the reason a key fails here. Wear, loss, and a missing spare usually are. The neighborhood detail that matters most for car keys is a plain one: the car is wherever you left it, and we come there.
Frequently asked questions
How much does car key replacement cost in Winnetka?
It depends on the key type, the make, model, and year, whether you have a working key to copy from, how many keys you want, and when and where you need service. We don't post numbers because they would be guesses. Call (213) 577-1366 with your vehicle details and we will tell you the cost before any work begins.
Can you make a car key if I've lost every key?
In many cases, yes. It takes more steps than copying a key, including confirming ownership and working out the key information for your vehicle. Some vehicles are dealer-only, and we confirm that by VIN and tell you honestly before we drive out.
Do you come to me, or do I bring the car in?
We come to you. Our mobile vans carry cutting and programming equipment, so the work happens where your vehicle is parked in Winnetka. You can also visit our storefront at 10740 Wilshire Blvd in Westwood.
How long does car key replacement take?
It varies with the key type and the vehicle, so we don't quote a time over the phone. Many jobs finish in one visit. We'll tell you what to expect for your car when you call.
What proof of ownership do you need?
We ask for your ID and something that connects you to the vehicle, such as the registration or title. We ask this on every car, because making a working key for a vehicle that isn't yours would be a serious problem for everyone involved.
What's the difference between a spare car key and a duplicate car key?
In everyday use they mean the same thing: an extra key for a vehicle that already has one. The point is that a copy from a working key is usually simpler and the more economical route than replacing a key when none are left.
Is a key from a locksmith as good as one from the dealer?
A key that is properly cut and programmed does the same job: it opens the doors and starts the engine. Where a dealer is the only route for your vehicle, we say so up front, and we confirm by VIN rather than guessing.
My remote works but the key won't start the car. What now?
That points to the key's transponder programming or to the ignition, not the remote buttons. We'd need to look at the key and the vehicle in person to tell which, so call (213) 577-1366 and describe what happens.
Can you cut a key for my car if the fob battery is just weak?
A weak fob battery can mimic a failed key, so it is worth trying a fresh battery first. If the key still doesn't work, call us and we'll find out whether it needs reprogramming or replacing.
