What happens when you have lost all your car keys?
Losing one key while a spare sits in a drawer at home is an annoyance. Losing all your car keys is a different problem, because there is nothing left to copy. A normal duplicate starts from an existing key. A replacement car key without the original has to be built from scratch, using information about the vehicle instead of a pattern in your hand.
That is more involved than most people expect. On many vehicles the key is not just a cut piece of metal. It is also paired electronically with the car, so a blade that merely turns in the ignition or door may still not start the engine. What your particular car needs depends on its make, model and year, and we confirm that by VIN rather than guessing over the phone.
Most people who call us about lost all car keys are standing next to the car, a bit stressed, and unsure whether the dealer or a tow truck is the only way out. Often it is not. A mobile automotive locksmith can usually do the work where the car is parked. The exceptions are real, and we will tell you plainly when a car falls into one of them (more on that below).
One quick check before anything else: if the key might be sitting inside the locked car, you have a lockout, not a lost key, and that is a simpler job. See our page on car lockout service in Carson for that situation.
How do we make a replacement car key without the original?
The details vary by vehicle, but the sequence of a lost-all-keys job looks like this. It is the same careful process whether it is a weekday afternoon or the middle of the night.
- You call (213) 577-1366 and tell us the make, model, year, where the car is, and whether any key at all is left, including a broken one or a valet key.
- We ask about your ownership documents. We will not make a key for a car we cannot connect to the person asking.
- We identify the key type from the VIN and your description: standard blade, high-security cut, key with a remote, or a push-button-start smart key.
- We work out how to cut the key. Depending on the vehicle, that means using key-code information tied to the VIN, or reading the lock itself to determine the cuts.
- We cut the new key to match the lock.
- We program the key to the vehicle so the car recognizes it. Where the vehicle supports it, we can also remove the lost keys from the car's memory so a stray key no longer starts it. We confirm that per vehicle.
- We test everything before you pay: the door lock, the ignition or start button, and any remote buttons that come with the key.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366What do you need to show us for a new car key?
Ownership checks are not a formality for us. A locksmith who makes keys to any car for anyone is a danger to every car owner in the city, including you. Expect us to ask for a few things, and have them ready when we arrive.
If some of these are not immediately at hand, tell us when you call. Often there is a sensible way to sort it out, and we would rather talk it through than have you discover a missing document at the car.
- Government-issued photo ID that matches the name on the vehicle paperwork.
- Registration or title showing you as the owner, or other proof you are legally entitled to the car.
- The VIN, which is usually visible at the base of the windshield or on the driver's door jamb label.
- The vehicle itself on location, since programming a new key generally requires access to the car.
- For leased or company vehicles, anything showing you are authorized to act for the owner.
Can every car be handled without going to the dealer?
No, and anyone who says otherwise should make you cautious. Many vehicles can be handled on site by a well-equipped automotive locksmith. Some cannot, or not reliably. Certain makes and certain model years have security systems where key-making information is held only by the manufacturer or its dealers. When we hit one of those, we say so at the start instead of letting you pay for a wasted trip.
Because the data we have about specific vehicles can be incomplete or even conflicting between sources, we do not make blanket promises about chip types or programming over the phone. We confirm by VIN and in person. If your car turns out to be dealer-only, we will explain what the dealer will likely need from you and whether towing the car to them makes sense.
If a dealer visit is unavoidable, you have not wasted your call. Knowing for certain, early, saves you from buying a key blank online that will not work or from waiting around for a technician who cannot finish the job.
For a broader overview of everything we do on vehicles, see our automotive locksmith service in Carson page. If you want to read about the replacement process in general terms, our car key replacement in Carson page covers it, and the transponder key programming page explains the electronic pairing step in more detail.
What affects the cost of lost car key replacement?
We do not publish prices on a web page, because the honest answer depends on the car. When you call, we gather the facts below and give you a quote before we start work. These are the real factors behind that number:
- Vehicle make, model and year. Some are more straightforward than others, and that drives how long the job takes and what equipment it needs.
- Key type. A plain metal key, a key with a remote, a high-security cut key and a push-button smart key are all different products with different costs.
- How the key information is obtained. Some vehicles allow cutting by code from the VIN; others require reading the lock, which takes more labor.
- The programming procedure. Some cars take a straightforward programming session; others need more steps or more specialized tools.
- Whether any key is left. Having one working key, even a spare you forgot about, can change the work and often makes it the lighter-cost option.
- How many keys you want. Making two at once is usually more economical than making one now and another later, since the setup work happens once.
- Where and when. A van traveling to you at night or from further away costs the company more than a daytime nearby call, and the quote reflects that.
- Condition of the ignition and locks. A worn ignition or a damaged lock can complicate programming and may need separate attention.

Call (213) 577-1366Ways to keep the cost reasonable
If you only need a working key to drive and do not care about the remote buttons, say so. A key without extra remote features is usually the more economical route, and in many cases a remote can be added afterward. Our key fob replacement page explains how that works. If there is any chance a spare key exists at home, with a partner, a roommate or a parent, check before you call. A call to retrieve that spare may be all you need.
Lost all your car keys in Carson: what it looks like here
Carson sits about 24 miles from our storefront at 10740 Wilshire Blvd in Westwood, so for this city the mobile van is the point. We come to your driveway, your parking space or the curb where you are stuck. We cover all three Carson ZIP codes: 90745, 90746 and 90747.
The scenarios we hear about follow how people live and move around here. In the Carousel Tract, Dominguez and Scottsdale, the typical call is someone parked at home who cannot find the only key, or whose spare went missing along with the main one. Those are usually calmer jobs, with the car in the driveway and the paperwork inside the house. Along the Avalon Boulevard and Carson Street corridors, it is more often a car in a lot or at the curb, with the owner away from home and needing to get the registration from somewhere before we begin.
Event days near Dignity Health Sports Park are their own situation. A lost key in a crowded lot, with the car boxed in or the owner far from home, is a hard moment. If you lose your keys on an event day, call us and tell us exactly where you parked. The lot layout and the crowds are not something we can promise to overcome, but we will plan around what you tell us.
Students near CSU Dominguez Hills sometimes find themselves with a lost key and no paperwork on hand, because the title is with a parent or a lender. That is workable if you call early and we talk through which documents will do. Shoppers at SouthBay Pavilion, and people who work in the warehouse and distribution buildings along the 405 industrial corridors, often find themselves far from a spare key and in no mood to tow a car. In those cases a mobile locksmith on site is usually the first thing to price against towing.
Not every Carson call ends the same way. If your vehicle is one of those dealer-only models, you will hear that from us directly, and we will help you work out the best path. Our mobile locksmith service in Carson page describes how our vans work around the city.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366What should you do before we arrive?
A few small steps make the job go more smoothly. None of them are required, but they help.
If the key snapped off in the ignition or a door lock rather than disappeared, that is a separate problem. See our broken key extraction page, and mention it when you call.
- Retrace your steps once more, including jacket pockets, bags and the place you last parked. Many lost keys turn up before anyone has to be called.
- Ask anyone who might have a spare, including family, roommates and a previous owner.
- Find the registration or title and your photo ID, and write down the VIN.
- Leave the car where it is unless we say otherwise. Moving it, especially by tow, can complicate things.
- If you are in a parking lot or on the street, tell us the exact spot, the nearest cross street or a landmark, and the color of the car.
- If your insurance or roadside plan mentions key coverage, check what it includes. We cannot tell you what your policy covers, but it is worth a call.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and that length of time matters for a job like this because lost-all-keys work is not something you want to learn on your car. We have a storefront in Westwood and mobile service vans, and the phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round. The person who answers is part of our company, not a call center. There are no dispatch middlemen passing your job to a stranger.
David, the owner and lead technician, oversees the work. That means someone with a long history in this trade stands behind how we identify keys, how we confirm ownership and how we handle the awkward cases where a car needs a dealer. We serve 140 cities across Los Angeles and Ventura counties, and Carson is one of them.
What we will not do is promise things we cannot know before we see the car. We will not tell you a key can definitely be made until we know the vehicle. We will not skip the ownership check to look more convenient. And we will give you the quote before we start.
How can you check that a car locksmith is legitimate?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for that license number before they start work on your car, including us. A real company will give it to you without fuss.
Other signs worth watching: a quote that changes after the technician arrives, a refusal to ask for ID or ownership proof, an unmarked vehicle, or a vague company name. Ownership checks are a good sign, not an annoyance. A locksmith who makes a key to your car without asking who you are would do the same for a thief.
If you need a spare made while you have a working key, that is much simpler. See our key duplication page.
Frequently asked questions
Can you make a car key if I have lost all of them?
In most cases, yes. We make the key from the vehicle's information instead of copying an original, then program it to the car. Some vehicles are dealer-only, and we confirm by VIN. If yours is one of those, we will say so up front.
Do you need the car with you to make a new key?
Generally yes. Cutting the key may be possible from vehicle data, but programming usually needs access to the car itself. That is one reason we bring a mobile van to wherever the car is parked.
What proof of ownership do I need?
Photo ID that matches the name on the registration or title, plus the VIN. If the car is leased or belongs to a company, tell us when you call and we will explain what shows you are authorized.
How much does a lost car key replacement cost in Carson?
It depends on the vehicle, the type of key, how the key information is obtained, how much programming is needed, how many keys you want, and where and when we come. We give you a quote after learning the make, model and year, before the work begins.
Will the lost key still start my car after you make a new one?
On vehicles that support it, we can remove lost keys from the car's memory so they no longer start it. Whether your car allows that depends on the make, model and year, and we confirm it in person.
Do I have to tow my car to the dealer?
Often not. Many vehicles can be handled on site. Some cannot, and for those a dealer visit is the honest answer. We will tell you at the start, so you do not pay for a trip that cannot finish the job.
Can you come to a parking lot near Dignity Health Sports Park or CSU Dominguez Hills?
Yes, we serve cars wherever they are in Carson, including lots near both. Give us the exact spot, the car's color and a nearby cross street or landmark, and have your ID and registration with you or reachable.
What if I only have a broken key or one key left?
Tell us when you call. Having a partial key or one working key can change the work and often makes the job simpler and less costly. A broken piece stuck in the ignition or door is a separate repair that we handle first.
Do you answer the phone at night and on holidays?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year, and a technician can head out to Carson when you need one.
