What happens when you have lost all your car keys?
Losing one key is an annoyance. Losing all of them is a different problem, because there is no working key left to copy. A basic duplicate is a trace-and-cut job that needs an original in hand. When the last key is gone, a new one has to be created from scratch, and on most modern cars that means more than cutting metal. The car also has to be told to accept the new key.
That is what lost car key replacement means at Wilshire Lock & Key. We build a new key from the vehicle's own information, cut it, and, where the car uses a chip or an electronic key, program it so the car actually starts. You do not need the original. In most cases you do not need to tow the car anywhere either. Some vehicles do require the dealer, and we explain which situations those are further down this page.
People in Winnetka tend to reach us in a handful of ways: keys dropped somewhere they cannot retrace, a bag or purse taken, a spare nobody can find, or a car bought used with only one key that has now disappeared. Whatever the cause, the first step is the same. Stop searching in circles and get the car's situation sorted properly. If you want the broader picture of how we handle new keys for every kind of vehicle, our car key replacement service page covers it, and this page focuses on the harder case where nothing is left to work from.
Can you get a replacement car key without the original?
Yes, in the large majority of cases. A replacement car key without the original starts with the vehicle itself. Every car is tied to a VIN, and the VIN, together with the make, model and year, tells us what kind of key the car uses and how it has to be cut. From there we either cut the key by code or read the lock to work out the cuts, and then, if the car has an immobilizer, we program the new key into the car's computer.
Which of those steps apply to your car depends on the key type. Some older vehicles use a plain metal key with no chip. Many newer ones use a transponder chip inside the head of the key, a remote head key with buttons built in, or a push-to-start smart key. Each one is handled differently, and the programming side of that work is covered on our transponder key programming page.
Here is the honest part. Chip and programming requirements vary a great deal between manufacturers and even between model years of the same car, and published information on this is not always consistent. So we do not promise an exact outcome over the phone based on a guess. We confirm by VIN and in person before we start, and we tell you what we find.
A small number of vehicles, depending on make, model and year, keep their key programming behind dealer-only equipment or security procedures that an independent locksmith cannot complete. If your car turns out to be one of those, we will tell you before any work begins, so you can decide how to proceed rather than paying for a visit that cannot finish the job.
One more point worth knowing: when all keys are lost, the lost keys are a security question as well as a convenience problem. Where the car's system allows it, we can have the old keys removed from the car's memory during programming, so a key that someone else is holding will no longer start the vehicle.

Call (213) 577-1366How we replace a lost car key, step by step
The process is the same whether you are calling at midday or in the middle of the night. Here is how it goes from the first call.
- You call (213) 577-1366. We ask for the make, model and year, where the car is parked, and whether it has a regular key, a key with buttons, or a push-to-start system.
- We confirm what the car needs by VIN. Reading the VIN and checking it against the vehicle tells us the key type and the programming approach, and it shows us early if the car is one of the dealer-only cases.
- We verify ownership. Before we make a key for any vehicle, we ask for photo ID and proof the car is yours, such as registration or title that matches the VIN. This protects you as much as it protects us.
- A mobile van comes to the car. Our technician brings the cutting and programming equipment to wherever the vehicle is, so you do not have to move it.
- We cut the new key. Depending on the vehicle, that is done by code or by reading the lock itself, and the key is test-fitted in the door and ignition before anything is programmed.
- We program the key to the car and test everything. We check that it starts the engine, locks and unlocks the doors, and that any remote buttons work, not just that it turns.
- We talk about a spare and about the lost keys. If the car's system allows it, we can remove the lost keys from its memory, and we strongly suggest making a second key while the equipment is already set up.
What to have ready before we arrive
A few things make the visit smoother. None of them are exotic, and if you are missing something, tell us on the phone and we will work out what can be done.
- Photo ID that matches the name on the registration or title.
- Proof of ownership for the vehicle: registration, title, or a loan or lease document that shows the VIN.
- The VIN, if you can find it. It is usually visible at the base of the windshield on the driver's side or on the door jamb sticker.
- The exact make, model and year, and whether the car was push-to-start or used a regular key.
- The car's location with a cross street or building name, so the van can find it without a long back-and-forth.
- Any detail about how the keys were lost. If they may have been stolen rather than misplaced, say so, because it affects what we recommend about removing the old keys.

Call (213) 577-1366How much does lost car key replacement cost in Winnetka?
We do not publish a flat figure here because there is no honest one. Lost car key replacement varies widely, and a number that fits a basic older key would badly mislead someone with a push-to-start car. What we can do is tell you exactly what moves the cost, so you can see why a quote is what it is.
Once we know your vehicle, we give you the price before we start work. If the answer is that the dealer is the only option for your car, we say that instead of leading you into a wasted visit.
- Key type. A plain metal key, a transponder key, a remote head key and a smart key are very different products, and the more electronics involved, the more the key itself and the programming cost.
- Make, model and year. Some manufacturers are straightforward and others have more involved security systems, which means more time and more specialized equipment.
- How the key is cut. Cutting by code is generally simpler than having to read and decode the lock, and not every car allows both.
- Programming complexity. Adding a key to a car that still has a working one is a different job from programming when every key is gone.
- Number of keys. A second key made during the same visit usually costs less than coming back later, since the equipment is already connected.
- Time and location. After-hours service and distance from our base are factors, which is why we confirm them on the phone rather than surprising you at the car.
Is a mobile locksmith or the dealer the more economical route?
For many cars, working with a mobile locksmith is usually the more economical route, mainly because there is no tow and no waiting for a dealer appointment. When the car has to be moved and the key made elsewhere, the tow becomes part of the real cost, and that is easy to overlook when comparing numbers. That said, it is not true for every vehicle, and for dealer-only cases the dealer is simply the answer.
Our approach is to look at the whole picture with you: the key, the programming, whether the car must be towed, and how soon you need to drive. Because we are a single company with our own vans, you also do not get passed along a chain of subcontractors, which keeps the price you hear on the phone connected to the price you actually pay. More on how that works is on our mobile locksmith page.

Call (213) 577-1366Where lost car keys tend to come up around Winnetka
Winnetka is a compact neighborhood in ZIP code 91306, built largely on postwar 1950s stucco tract homes, with apartment buildings lining stretches of Sherman Way, Roscoe Boulevard and Vanowen Street. That mix matters for lost car keys, because the car is often only one of the things on the missing key ring.
Take the Sherman Way and Roscoe Boulevard corridors, where apartment lockouts are one of the common scenarios. A resident who loses a key ring may be locked out of the car and the front door at the same time. We can deal with the car side, and if the apartment door is also stuck shut, our apartment lockout service page explains how that works. The same goes for a house in the tract-home streets: if the ring held a house key and it might be in someone else's hands, rekeying the home is worth a conversation, and we can raise it while we are there.
If you are stranded near the Winnetka Recreation Center at Roscoe Boulevard and Winnetka Avenue, around Runnymede Park, or along the Winnetka Avenue corridor near Pierce College, just give us the cross street and the car's description. We come to you wherever the vehicle is parked, and we do the cutting and programming right there.
Weather plays a small part too. Valley summers here are hot and dry, and sitting beside a car with no key is miserable in the afternoon sun. If you can wait somewhere shaded or indoors, do, and we will coordinate arrival with you by phone.
Why call Wilshire Lock & Key for a lost car key
We have been in business since 1987. Our storefront is at 10740 Wilshire Blvd in Westwood, and we run mobile service vans that cover 140 cities across Los Angeles and Ventura counties, Winnetka included. The phone, (213) 577-1366, is answered 24 hours a day, seven days a week, all year.
We are one company. The person who answers, the technician who drives to you, and the shop behind them are all us, not a dispatch center that sells the call to whoever is nearest. David, the owner and lead technician, oversees the work, so the standards do not change between a daytime call and a 3 a.m. one.
A word on licensing, because it is worth checking with any locksmith. California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Before anyone starts work on your car, ask them for it. That is a fair question to put to us too.
What we will not do is hand you a rosy answer we cannot back up. If your car requires the dealer, we say so. If your key type means a longer visit, we tell you why. And if the old key turns up later, we will explain what that means for the new one.

Call (213) 577-1366What to do, and what not to do, while you wait
There are a few simple things that save grief once the keys have clearly gone missing.
- Check the obvious places once, calmly: pockets, the last place you parked, and anywhere you stopped. A call to a store or restaurant can settle it quickly.
- Do not keep trying the ignition with a worn spare or an unidentified key. It will not help and can lead to a stuck key in the lock.
- Be careful about ordering a blank or key fob online before we confirm what your car uses. A mismatched part is a common waste of money and cannot always be used.
- If you think the keys were stolen, say so, and think about whether the address on your registration or anything else in the car makes someone else's access a risk.
- If your key breaks off in a lock rather than going missing, that is a separate job, handled under broken key extraction.
When it is not really a lost-key problem
Not every key emergency is a lost-all-keys situation, and it helps to pick the right service. If your key is sitting on the seat or in the ignition and the doors are locked, you need a lockout, not a new key; our car lockout page covers that. If you have a working key but it turns badly or will not stay in the ignition, the ignition may be worn, and the right page is ignition repair. If the key itself is fine and only the remote buttons have died, a key fob replacement is the more targeted fix.
And if you still have one working key, do yourself a favor: have a spare made now through key duplication before it is lost too. Copying a key you hold is far simpler than starting from nothing.
Frequently asked questions
Can you make a car key if I have no keys at all?
Yes. Lost car key replacement is for exactly that situation. We identify your car by VIN, cut a new key from that information, and program it to the car if it uses a chip or electronic key. Whether we can finish on site depends on the make, model and year, and we confirm that by VIN and in person.
Do I need to tow my car to get a new key?
Usually not. Our mobile vans bring the cutting and programming equipment to wherever the car is parked. The exception is a vehicle whose programming is dealer-only, in which case the car may need to go to the dealer, and we will tell you that before any work begins.
What proof of ownership do you need?
We ask for photo ID and something that ties you to the car, such as the registration or title showing the VIN. We do this for every vehicle, because making a key for a car without checking who owns it would not be responsible.
Will my lost keys still start the car after you program a new one?
Where the car's system allows it, we can remove the lost keys from its memory during programming so they stop working. Not every vehicle supports this, so we confirm what is possible for yours. If you suspect theft, tell us on the call.
How long will lost car key replacement take?
It depends on the key type and the car. A plain metal key is quicker than a smart key that has to be programmed to the vehicle. We will give you a realistic idea once we know the make, model and year, rather than quoting a time we cannot stand behind.
Is it cheaper to go to the dealer?
Not necessarily. The dealer may require towing and an appointment, and those add to the real cost. For many cars a mobile locksmith is usually the more economical route, but not for every one. If your car is a dealer-only case, we will say so.
Can you come to my apartment building in Winnetka?
Yes. We work wherever the car is, including apartment lots and streets along Sherman Way, Roscoe Boulevard and Vanowen Street. Give us the address or cross street when you call at (213) 577-1366. If your apartment key was on the same ring, ask about that as well.
Should I get a spare key made at the same time?
We recommend it. Once the equipment is connected to your car, an extra key is simpler than starting over later. Having a spare also means the next lost key is an inconvenience rather than an emergency.
What if I find my old key after you make a new one?
If we removed the lost keys from the car's memory, the old one will no longer start the car, and we will have told you that. Keep the new key and the paperwork, and call us if you want to talk through what to do with the old key.
