What car key replacement really involves
A car key is not one thing. Depending on the vehicle, it might be a plain cut piece of metal, a key with an electronic chip inside the head, a key with remote buttons built in, or a push-button smart key that never goes in a lock at all. Each one is made differently, and that is why a quick answer over the phone is never the whole story.
Car key replacement means producing a working key for your specific vehicle when you have none, one that is worn out, or one that has stopped starting the car. Usually that has two parts: cutting the metal blade so it turns the locks and ignition, and programming the electronics so the car recognizes the key. Some keys need only one of those, some need both, and a few vehicles have extra steps.
We do this work at your car, not in a back room you have to get to. A mobile service van carries the cutting and programming equipment, and the storefront at 10740 Wilshire Blvd in Westwood backs it up. If you are in North Hills and the car is parked at home, at work or in a lot, that is where we do the job.
How does mobile car key replacement work in North Hills?
The process is the same whether you need a spare made before something goes wrong or you are standing next to a car you cannot start. What changes is how much information we need to gather first.
Here is the sequence we follow on a typical call.
- You call (213) 577-1366. A person answers, any hour, any day. Tell us the make, model and year, what keys you still have (if any), and where the car is parked.
- We ask for the VIN. It is usually visible through the windshield at the driver's side dashboard corner and also on your registration or insurance card. The VIN lets us confirm the right key type instead of guessing.
- We tell you plainly what the job looks like for your vehicle, what factors drive the cost, and whether anything about it is unusual, such as a dealer-only step. If we cannot do it, we say so before anyone drives out.
- A technician comes to the car. We verify that you are the owner or authorized user before making a key. Expect to show ID and proof of ownership such as registration or title.
- We cut the key, program it to the vehicle, and test it. That means locks, ignition and, where the key has them, remote functions, before we call the job finished.
- If it is a lost-key situation, we also make sure every key you want to keep working is programmed, and we discuss what to do about the lost one so it cannot be used.

Call (213) 577-1366Spare key, duplicate key or full replacement: which one do you need?
People use these words loosely, and the difference matters for how the job goes and what it involves.
A duplicate car key is a copy made from a key you still have. A spare car key is the key you keep in reserve, often made the same way. With a working key in hand, the process is generally more straightforward than starting from nothing, because the car already has a key it trusts. Making a spare before you lose the only one is almost always the more economical route, and the less stressful one.
A replacement after loss is different. If every key is gone, there is nothing to copy. The key has to be created for the vehicle from its identifying information and then matched to the car. That is more involved, and we cover the specifics on our page about lost car key replacement in North Hills.
A key that is damaged but still in your hand sits in between. A cracked head, a worn blade or a key that works the door but not the ignition can often be replaced by creating a fresh one, and the old one is a helpful reference.
- Duplicate or spare: you have at least one working key and want another.
- Replacement, all keys lost: no working key exists; the key must be originated for the vehicle.
- Worn or damaged key: still partly functional; we replace it before it fails completely.
- Remote-only problem: the key starts the car but the buttons do not work. That is a separate repair path, covered under key fob replacement.
Car key cutting, chips and programming: what we can and cannot promise by phone
Car key cutting is the physical side. Some cars use a conventional edge-cut blade, others use a thicker blade with a cut along its center. Cutting has to match the vehicle's locks exactly, and the blade needs to be clean enough that it does not wear the ignition.
Programming is the electronic side, and this is where honest answers matter. Whether your vehicle needs a chip, how that chip gets registered, how many keys the car allows, and whether the process needs special access all vary by make, model and year. We do not make blanket claims about what works for everyone, because they would not be true. We confirm by VIN, and in person if needed, before we say what your specific vehicle requires.
If the key is a transponder type and the car simply needs to learn it, our page on transponder key programming goes into more detail on that part of the job.

Call (213) 577-1366Ignition key replacement: is it the key or the ignition?
When a key will not turn, the instinct is to order a new one. Sometimes that is the answer. A badly worn key can fail to line up the pins inside the ignition cylinder, and a fresh cut fixes it immediately.
Other times the key is fine and the ignition cylinder is the problem. If a brand new key behaves the same way as the old one, the wear is likely inside the cylinder. That is a different repair, and we would rather say so than sell you keys that do not solve the issue. Cylinder work is covered under ignition repair.
The way we sort this out is simple. We inspect how the key enters, turns and returns, and we compare it with how a known good key behaves. If the key is the culprit, ignition key replacement is quick to confirm. If the cylinder is the culprit, we tell you what that repair involves before any work starts.
What affects the cost of car key replacement?
We do not quote numbers on a web page, because honest pricing for car keys depends on facts we do not know until you tell us about the vehicle. Anyone who gives you a flat figure without asking the make, model and year is guessing, or planning to adjust it later.
These are the things that move the cost, in roughly the order they matter.
- Key type: a plain cut key, a chip key, a remote-head key and a smart key are different products with very different build requirements.
- Make, model and year: some vehicles are straightforward and others have more demanding security.
- Whether you have a working key: copying from an existing key is generally lighter-cost than originating one when all are lost.
- Number of keys: making two at the same visit is usually more economical per key than returning later.
- Vehicle location: a car at your driveway is simpler to reach than one in a hard-to-access spot, and distance from our base can be a factor.
- Time of day: after-hours and holiday calls involve a technician being called out outside normal hours.
- Dealer-only steps: if something has to be done through a dealer, that cost is separate and we tell you up front.
When a dealer is the only option
We would rather you hear this from us now than discover it halfway through a job: not every vehicle can be handled by a locksmith. For some makes, models and years, certain keys or key codes can only be obtained through the dealer, or the process requires authorization we cannot get independently.
We do not guess about this. When you call, we ask for the VIN and work out whether your car is something we can do on site. If the data for your vehicle is unclear or conflicting, we say that plainly and confirm in person instead of promising something we are not sure of. If a dealer is required, we tell you that before sending a technician, so you are not paying for a visit that cannot produce a key.
In cases where a dealer step is needed for part of the job, we can often still help with the other parts, such as getting the car to the dealer or finishing the cutting and programming afterward. We will lay out what is realistic.

Call (213) 577-1366Why call Wilshire Lock & Key for your car key
We have been in business since 1987. That is a lot of years of keys, cars and the odd problems people bring to a locksmith at the worst possible time. We serve 140 cities across Los Angeles and Ventura counties, and North Hills is one of them, roughly 15 miles from our Westwood base.
We are one company. When you call (213) 577-1366, you are talking to us, not a dispatch center that sells your job to whoever picks it up. That matters in automotive work, where the person who understands your vehicle is the person who should be doing the job. David, the owner and lead technician, oversees the work.
We run a real storefront at 10740 Wilshire Blvd plus mobile vans, so there is a physical business behind the phone number. We answer 24 hours a day, 7 days a week, year-round.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they work on your vehicle. That is a fair thing to ask of us as well as anyone else. For a broader view of what we do for vehicles, see our automotive locksmith page.
Car keys around North Hills: west, east and the corridors
North Hills (ZIP 91343) is a split community. The 405 divides it into North Hills West and North Hills East, and that division shapes where people park and how they live. Most of the area is made up of 1950s ranch tracts, but there are apartment clusters along Parthenia and Sepulveda, and North Hills West has gated townhome and condo communities.
That mix affects car key calls in practical ways. In the apartment buildings along the Sepulveda Boulevard corridor, a lot of cars live in shared lots or tight parking, and a lost key often turns into a lockout at the same time. If you are locked out as well as keyless, start with our car lockout service, and we can move on to making the key once you are in. In the gated townhome communities of North Hills West, the issue is often access: we coordinate with you so the van can get to the vehicle.
In the ranch tract streets of North Hills East, cars are usually in driveways or on the street, which makes mobile service straightforward. Along Nordhoff Street and Parthenia Street, many calls come from people who lost a key at work or while running errands; we can meet you at the car in a business lot. Around the VA Sepulveda Ambulatory Care Center campus area, or near the Mid-Valley Regional Branch Library and North Hills Community Park, someone who set a key down and cannot find it can have the same situation anywhere. We go to where the car is.
The valley location means hot summers. Heat is hard on door hardware and weatherstripping, and an unhappy summer afternoon is no time to be stranded beside a car you cannot start. It is another reason to have a spare cut ahead of time. North Hills also has no coastal corrosion factors, so keys here generally fail from ordinary wear, not salt-air damage.

Call (213) 577-1366Before you call: what to have ready
A few minutes of preparation makes the call more productive and often shortens the visit. You do not need everything on this list, but the more you have, the more precisely we can describe the job.
- Year, make and model of the vehicle.
- The VIN, from the dashboard corner or your registration or insurance card.
- Photos or the physical keys you still have, even if broken.
- Your ID and proof of ownership, such as registration or title.
- The exact location of the car and any access issues, such as a gate, a garage code or a parking permit.
- How many keys you want made, and whether you need remote functions.
Planning a spare so you do not need an emergency
The easiest car key job we do is the one nobody is rushing. If you have only one working key, making a spare is the single most useful thing you can do before it is lost. It saves you from being in a worse position later, where all keys are gone and the job gets more involved.
We can also help with ordinary key copies on non-vehicle keys, if you want to cover your home and car in one visit; see key duplication. And if you want us to come to you instead of heading across town, our mobile locksmith service covers North Hills. Reach us anytime at (213) 577-1366.
Frequently asked questions
Can you make a car key without the original?
In many cases, yes. When no key exists, we originate one for your vehicle based on its identifying information and then program it to the car. Whether that is possible on site depends on the make, model and year, so we confirm by VIN first. If your vehicle is a dealer-only case, we tell you before sending anyone.
Do you come to me in North Hills, or do I have to bring the car?
We come to you. Our mobile vans carry cutting and programming equipment, so the work is done at the car, whether it is in a driveway in North Hills East, a lot along Nordhoff Street or a gated townhome community in North Hills West.
Is same day car key replacement possible?
Often, yes, and we aim to finish in a single visit when the vehicle allows it. It depends on the key type and on whether we can confirm your vehicle's requirements by VIN. We will be straight with you on the phone if your car needs something that cannot be done the same day.
How much does a replacement car key cost?
We do not quote numbers online, because the cost depends on the key type, the vehicle, whether you have a working key to copy, how many keys you want and when you need service. Call (213) 577-1366 with your make, model, year and VIN, and we will explain what applies to your car before any work begins.
What is the difference between a duplicate key and a spare key?
A duplicate is a copy made from a working key. A spare is simply the extra key you keep in reserve; it is often made as a duplicate. Both are generally simpler than replacing a key when every key is lost, which is why making a spare early is usually the more economical route.
What do you need from me to make a car key?
We need to verify you can have the key: ID plus proof of ownership such as registration or title. We also ask for the VIN, and the year, make and model. Having any existing keys on hand, even damaged ones, helps.
My key goes in the ignition but will not turn. Do I need a new key?
Maybe. A worn key can fail to turn, and a fresh cut can fix it. But if a new key behaves the same way, the ignition cylinder is likely the problem, which is a different repair. We check which it is before you pay for the wrong fix; see our page on ignition repair.
Will every car key be something you can do, or do I need the dealer?
Not every vehicle. Some makes, models and years have steps that only a dealer can complete. Where our data on a vehicle is unclear or conflicting, we say so and confirm by VIN or in person. If a dealer is required, we tell you before a technician is sent out.
Is your locksmith company licensed?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith, including us, for it before they work on your vehicle. Asking is a normal and sensible step. You can also call (213) 577-1366 or visit our contact page if you have questions.
