What is lost car key replacement when you have no original?
Lost car key replacement is the job we do when every key to a vehicle is gone: no spare in a kitchen drawer, no second fob at home, nothing to copy. Because there is no original to duplicate, the new key has to be built from information about the car rather than from a key in our hands. That is the real difference between this job and ordinary key duplication, which always starts with a working key.
In practice it means cutting a key to fit your vehicle's locks and, where the car requires it, programming that key so the car accepts it. What your particular car needs depends on its make, model, year and the type of key it uses. We do not guess at that from the phone. We confirm by VIN and, when it matters, by looking at the car in person before we tell you what the job involves.
A replacement car key without the original is a normal request for us, and it is a different situation from having one working key and wanting a spare. If you still hold one key, our page on car key replacement covers that broader picture. This page is about the all-keys-lost case.
What should you do first if you have lost all your car keys?
Before you call anyone, a short, careful search is worth the effort. A key found in a coat pocket saves everyone a trip. If you have looked and it is truly gone, work through the list below so the call goes quickly.
- Check the obvious places one more time: jacket and pants pockets, the bag you carried, the table or counter where you set things down, and the seat of anywhere you sat.
- Retrace your route if you can, especially if you were outdoors, at a trailhead, or somewhere you took things in and out of your pockets.
- Do not force the door, pry at the ignition, or pull apart the steering column. Damage there can turn a key job into a repair job.
- Gather your photo ID and anything that shows the car is yours, such as the registration or title. Have the VIN ready if you can read it from the dashboard near the windshield or from the label on the driver's door jamb.
- Note exactly where the car is and what the access is like: street, driveway, parking lot, or a narrow hillside lane.
- Call (213) 577-1366. The phone is answered 24 hours a day, 7 days a week.

Call (213) 577-1366How do we make a replacement car key without the original?
Every vehicle is a little different, but the work follows the same order. Our vans are set up to do the job where the car is parked, so you do not have to arrange a tow just to get a key. That is the whole point of our mobile locksmith service. Where a particular car cannot be handled in the field, we say so up front.
- You call and tell us the year, make and model, what kind of key the car used (a metal blade, a key with a plastic head, a push-button start fob), and where the car is.
- We ask for the VIN and talk through what you can show us for ownership. This is where we find out whether the job looks straightforward or needs extra steps.
- A technician comes to the car with cutting and programming equipment.
- We check your ID against the paperwork for the vehicle before any key is made.
- We obtain the cutting information for your vehicle. Depending on the car, that comes from the VIN or from working from the lock itself.
- We cut the new key and, if the car calls for it, program it so the vehicle recognizes it.
- We test it properly: doors, trunk, ignition, and any remote functions on the key, before we call the job done.
Related work you might need on the same visit
Some lost-key jobs carry a second need with them. If your key has a chip in it, the programming side of the work is covered in more detail on our page for transponder key programming. If your car uses a remote or proximity fob, key fob replacement explains how that type differs.
One question people ask is whether the lost key can be turned off so a stranger cannot use it. Whether that is possible depends on the vehicle, and we confirm it per car rather than promise it in general. Ask us when you call and we will tell you honestly what your car allows.
What affects the cost of replacing a lost car key?
We do not publish numbers on a page like this, because an honest number depends on your car. What we can do is tell you exactly what moves the cost up or down, and give you a figure for your vehicle before we start work.
- The vehicle itself: make, model and year decide what kind of key it takes and how it must be set up.
- The type of key: a plain metal key is a lighter job than a chipped key, and a push-button start fob is a different job again.
- Whether programming is required, and how involved that programming is for your car.
- How many keys you want made. Having a spare made while we are already there is usually the more economical route compared with calling us back later.
- The condition of the ignition and door locks. If a lock is worn or damaged, you may also need ignition repair, which is its own line of work.
- Where the car is and what hour you call. A mobile visit at night to a hard-to-reach spot is not the same effort as a daytime visit to an open driveway.
- Whether the car turns out to be one that only a dealer can handle. If so, we tell you that plainly instead of sending a van for nothing.

Call (213) 577-1366What do you need to show to get a new car key made?
A locksmith should never make a key to a car on someone's say-so. We ask for photo ID and something that connects you to the vehicle, such as the registration or title. We ask every time. It protects you as much as it protects us.
If your paperwork was in the car or on the ring you lost, call and tell us what you do have. There are usually other ways to show ownership, and we will tell you what can work for your situation. If the vehicle belongs to an employer, a leasing company or a family member, tell us at the start so we can say what we will need.
Lost car key replacement in Sierra Madre: hillsides, trailheads and ZIP 91024
Sierra Madre is a small foothill town, and ZIP 91024 packs a lot of different parking situations into a small area. Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 27 miles from town, which is exactly why we work as a mobile service. You do not need to get to us. We come to the car.
The Mount Wilson Trail trailhead and Bailey Canyon Wilderness Park are a good example of how this job starts here. You head out with a key in a pocket, you take layers off and on, and by the time you are back at the car the key is somewhere on the hillside. If that is your situation, check your pack and the first stretch of trail if you can do so safely. If it is gone, we make a new key at your car. In hot, dry weather, tell us on the call how you are doing for water and shade so we know what you are dealing with. If a child or pet is locked inside a hot car, call 911 first.
Where the car sits shapes the visit. Around Downtown Sierra Madre and the Kersting Court area, it is usually about finding the right curb or lot. On the Baldwin Avenue corridor and the Sierra Madre Boulevard corridor, the car is often on the street, so a precise address or cross street helps us a great deal. In Sierra Madre Canyon, narrow lanes can make it hard to get a van close, so tell us if the car is tucked in or blocked. On the north hillside area below Bailey Canyon, tell us about the slope and where the nearest safe place to work is. If you are just across the line near Hastings Ranch in Pasadena or near Arcadia Highlands, give us your address and we will sort out the rest.
One more local point: most homes here are older single-family houses with legacy hardware. If your lost key ring held both car and house keys, the car is only half the problem. Handle the car first with us, then ask about the house locks while we are talking.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and David, the owner and lead technician, oversees the work. We run a storefront in Westwood and mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties. When you call, you are dealing with one company, not a dispatch service passing your job to whoever is free. The phone is answered around the clock, every day of the year.
We also tell you what we cannot do. If your car needs a dealer, we say so. If we cannot confirm what a key will take until we see the car, we say that too. And if you want to check any locksmith's credentials, including ours, ask for their license. California requires locksmith companies to hold a BSIS LCO license, and a reputable company will show it to you without fuss.
When is a lost car key a dealer job?
Honestly, sometimes. Some vehicles have key systems that are hard to handle outside a dealership, and which ones those are depends on the exact vehicle. We will not claim to know a car's category by make alone. That is why we ask for the VIN first.
If your car turns out to be dealer-only, we tell you during the phone call, before anyone drives out. If we can do part of the work, such as getting you into the car, we explain which part. If it is not something we can complete, you are better off hearing it from us at the start than finding out after a van has arrived.
How do you avoid losing every key again?
Once the new key works, take five minutes to avoid a repeat. Have a spare made while we are there. Keep that spare somewhere other than your main ring, and not hidden on the car. Write the VIN in your phone, since it is the first thing any locksmith or dealer will ask for. And if you spend time on trails, give your key a dedicated zipped pocket or a clip so it does not slide out as you change layers.
Frequently asked questions
Can you really make a car key if I have lost all of them?
Yes. Making a key with no original is what lost car key replacement means. We work from the VIN and the vehicle itself rather than from a key. What your car needs depends on its make, model and year, so we confirm by VIN or in person before we describe the job.
How long does a lost car key replacement take?
It depends on the car, the type of key and where the vehicle is parked, so we do not quote a fixed time. When you call (213) 577-1366, we ask about the vehicle and location and tell you what to expect for your situation.
Do I need to tow my car to you?
Usually not. Our mobile vans come to the car in Sierra Madre. If your vehicle turns out to need dealer work, we tell you that on the phone so you can decide before arranging a tow.
Do you need the VIN to make a replacement car key without the original?
We ask for it, because it is the fastest way to confirm what your vehicle takes. You can find it on the dashboard near the windshield or on the driver's door jamb label. If you cannot get to it, call anyway and we will work out the next step together.
I lost my key hiking near the Mount Wilson Trail. What should I do?
If it is safe, check your pack, your pockets and the first part of the trail. If you cannot find it, call us and tell us where the car is parked. We make the new key at the vehicle. If anyone or any pet is locked inside a hot car, call 911 first.
Will my lost key still start the car after you make a new one?
That depends on the vehicle. For some cars the old key can be disabled, and for others it cannot be handled in the same way. We confirm per car rather than promise it, so ask us when you call.
Is a locksmith more economical than the dealer for a lost car key?
Often it can be, mainly because we come to you and you avoid towing, but it depends on the vehicle. Some cars can only be handled by a dealer, and we say so plainly. We give you a figure for your car before we start work.
What if my registration is in the car I cannot open?
Call us and tell us what proof you do have, such as photo ID and other documents tied to the vehicle. We will explain what can work. We do not make keys without some verification that the car is yours.
Do you come out at night and on weekends in Sierra Madre?
Yes. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. After-hours visits can affect the cost, and we explain that when you call.
My house keys were on the same ring. Should I do anything about the house?
It is worth considering, especially if you do not know where the ring went. Handle the car first, then ask us about the locks at home while we are on the phone. Older homes often have legacy hardware, and we can look at what yours needs.
