What does it mean when you've lost all your car keys?
Losing one key is an annoyance. Losing all of your car keys is a different problem, because there is nothing left to copy. A locksmith can't duplicate a key that no longer exists, so the job changes from copying to creating. We build a new key for your specific vehicle, cut it to the right pattern, and on most modern cars program it so the engine will actually start.
That is what a replacement car key without the original really involves. It is a bigger job than duplication, which is why it has its own page apart from our general car key replacement service. The call usually sounds the same every time: you have retraced your steps, checked your pockets, your bag, the couch cushions, and the parking lot, and the keys are simply gone.
Before you commit to a full replacement, check two things. First, make sure the key isn't just locked inside the car. If you can see it on the seat, you need a car lockout rather than a new key. Second, look for any spare, including a valet key, one with a family member, or one in a drawer at home. A single working key makes the whole job simpler. If neither applies, you are in true all-keys-lost territory, and that is exactly what we handle.
How do we replace a car key when there is no original?
The process is the same in outline for most vehicles, though the details depend on the make, model, and year. Here is how a typical call goes from our end.
- You call (213) 577-1366. We ask for the make, model, and year, where the car is parked, and whether any key at all, including a valet key, exists anywhere.
- We confirm the vehicle by its VIN and confirm that you are the owner. Expect to show photo ID and registration or title that matches the car. We won't make keys for a vehicle without that, and you wouldn't want a locksmith who would.
- A mobile van comes to the car. If the car is locked, we open it first without damaging the door or the lock.
- We work out the correct key cut for your vehicle, using VIN-based key data where it is available, or by reading the lock itself where it is not.
- We cut the new key on the van, so you aren't waiting on a shop to open.
- We program the key to the car. On vehicles with an immobilizer chip, that means connecting to the car's system and registering the new key. Where the vehicle allows it, we also remove the lost keys from the car's memory so a key someone else picked up will no longer start it.
- We test everything before we leave: lock, unlock, start, shut off, remove, and restart, plus any remote buttons that are part of the key.

Call (213) 577-1366Which cars can we do on-site, and when is the dealer the only route?
Most people want a straight answer here, so here it is. Many vehicles can be handled by an automotive locksmith in the field, and that is the bulk of our all-keys-lost work. But not every car. Some makes, models, and years restrict access to their key data, and a few require a procedure or secured authorization that only the manufacturer's dealer can perform. In those cases we will tell you so plainly rather than let you wait for a van that can't solve the problem.
We don't guess from the driver's seat of a phone call. Chip type, key type, and what the car's computer will accept vary by vehicle, and the information online is often incomplete or contradicts itself. So we confirm by VIN and in person before promising anything. If your car turns out to be a dealer-only case, you will hear that early.
Key type matters too. A basic mechanical key, a transponder key, a remote-head key, and a push-button smart key are four different jobs. If your lost key included a remote or proximity fob, see our pages on transponder key programming and key fob replacement for how each type works. If your ignition cylinder is worn or damaged, that is a separate repair, and our ignition repair page explains when it becomes part of the picture.
What affects the cost of replacing lost car keys?
We don't quote numbers on a web page, because a number given without your VIN would be a guess, and a guess helps nobody. What we can do is explain what moves the cost up or down, so nothing on the final bill surprises you.
Once we know your vehicle, we walk through which of these apply before work begins. For many people, having the work done where the car sits is usually the more economical route compared with arranging a tow to a dealer, but that is not true for every vehicle, and we will say so if yours is an exception.
- Make, model, and year: some systems are far more involved to program than others.
- Key type: a plain cut key, a transponder key, a remote-head key, and a smart key each take different parts and different time.
- How many keys you want made: cutting and programming a second key during the same visit is usually less work than a separate trip later.
- Access to key data: whether the cut and code can be pulled by VIN or the lock has to be read by hand.
- Whether the car is locked and needs to be opened first.
- Location and time of day: after-hours calls and distance both factor in.
- Condition of the ignition and door locks: a worn cylinder can complicate cutting and programming.
- Dealer-only vehicles: if the manufacturer controls the process, our part of the job may shrink or disappear.

Call (213) 577-1366Lost car key replacement in South El Monte: where these calls come from
South El Monte is compact. Postwar single-family tracts, most of them built in the 1940s through the 1960s, sit directly beside light-industrial parcels, and ZIP 91733 covers both. That mix shapes where a lost-key call actually happens. It might be a driveway on a residential block near the New Temple Park residential area, a lot along the Garvey Avenue corridor, or a parking area on the Santa Anita Avenue corridor.
One scenario we can see clearly is the Rush Street industrial district. We already do warehouse padlock, hasp, and roll-up door service there, so the area is familiar. A lost car key in that setting often means a work vehicle or personal car sitting in a lot while the keys are somewhere between the loading dock and the breakroom. If keys vanish at the end of a shift and the car is the only way home, that is a call we take at any hour, day or night. The same goes if your keys disappear during an afternoon at New Temple Park or on the Whittier Narrows edge to the south of the city.
The climate adds a practical note. South El Monte sits in an inland basin with hot, dry summers, and while the open space at Whittier Narrows brings some evening cooling, a parked car in afternoon sun is not a pleasant place to wait. If you are stuck with a dark interior and no keys, find shade, call us, and tell us where the car is and what it looks like.
Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 26 miles from South El Monte, so we are coming to you by mobile locksmith van rather than from around the corner. We won't pretend otherwise. When you call, we will tell you what to expect for arrival based on where you are and what is already on the board.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and all-keys-lost work is the kind of job where experience matters, because it rewards knowing when something is going wrong before it costs you money. We run a real storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024, plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, South El Monte among them.
When you call (213) 577-1366, you reach us, not a national call center that sells your job to whichever contractor answers. One company takes the call, sends the van, and does the work, with no dispatch middlemen in between. David, the owner and lead technician, oversees our automotive work, so a hard vehicle doesn't get handed off to whoever happens to be free.
The phone is answered 24 hours a day, 7 days a week, all year. Lost keys don't keep business hours, and neither does our phone. Our broader automotive locksmith page covers the rest of what we do for vehicles, but this page is about one thing: getting you a working key when you have none.

Call (213) 577-1366What should you do while you wait, and what should you avoid?
A few small decisions before we arrive can save time and trouble.
Do these things:
- Find your VIN. It is on the driver's-side dash near the windshield, on the door jamb sticker, and on your registration or insurance card.
- Have your photo ID and registration or title ready. Without proof of ownership, no reputable locksmith will cut a key.
- Write down the make, model, year, and any details about the lost key, including whether it had a remote or buttons.
- Check whether anyone else has a key, even a valet key that came with the car.
- Stay somewhere safe, in the shade if you can, and tell us the exact location of the car.
What should you avoid?
Don't buy random key blanks online hoping to program them yourself. A blank that is not matched to your car's system can waste both money and time. Don't pay any deposit to a company that won't give a business name or a street address. And don't try to force the ignition or door. Damaging the lock turns a key problem into a lock problem, and that makes the job larger.
Once you have a working key, make a spare. Duplicating from a key you already own is much simpler than all-keys-lost work, and our key duplication service exists for just that. If the lost keys were taken along with something showing your address, such as a wallet or a bag, think about whether your home locks need attention too. Ask us about it on the call.
How can you check that a locksmith is legitimate?
California requires locksmith companies to hold a locksmith company license, known as an LCO license, issued through the state's Bureau of Security and Investigative Services (BSIS). Ask any locksmith company for its license number before work starts, and verify it with BSIS. It takes a moment and protects you.
Beyond the license, watch for the usual warning signs. A company that only gives a vague phone number, won't name a business, refuses to explain what affects the price, or doesn't ask for proof of ownership is not one you want near your car. A legitimate locksmith asks for your ID and registration, tells you plainly what the job involves, and explains what is different about your vehicle. If you hear something that doesn't fit, ask. Good technicians would rather answer questions than lose your trust halfway through the job.
Frequently asked questions
Can you make a car key if I have no original key at all?
Yes, in most cases. That is what all-keys-lost work is. We create a new key from your vehicle's VIN and key data, or by reading the lock, cut it, and program it to the car. A few vehicles are dealer-only, and we confirm by VIN and in person before promising anything.
Do I need to prove the car is mine?
Yes. Expect to show photo ID plus registration or title that matches the vehicle and its VIN. We ask every time. It protects you, because it means nobody can walk up to your car and have a key made for it with a story.
Will my lost key still start the car after you make a new one?
On many vehicles we can erase the lost keys from the car's memory when we program the new one, so the old key will no longer start it. Whether that is possible depends on the vehicle, and we confirm what your car allows during the visit.
Do you come to me in South El Monte, or do I need to tow the car?
We come to you. Our mobile vans cut and program keys at the vehicle, so you usually don't need a tow. We are based in Westwood, roughly 26 miles away, so we will tell you what to expect on arrival when you call (213) 577-1366.
Can you do my car on-site, or does it have to go to the dealer?
Many cars can be done on-site. Some makes, models, and years restrict key access, and a few need the dealer's own procedure. We don't guess over the phone. We confirm by VIN and in person, and if yours is dealer-only, we will say so straight away.
How long will it take?
It depends on the vehicle and key type. A simple cut key is quick, while a transponder or smart key takes longer because programming is involved. We don't quote times without the VIN. We will give you a realistic picture when we know your car.
How much will a replacement key cost?
We can't responsibly give a number without your VIN. The cost depends on the make, model, and year, the key type, how many keys you want, whether the car is locked, where it is, and the time of day. We walk through what applies to your car before work starts.
Can I get a spare while you are already there?
Yes, and we suggest it. Making a second key during the same visit is usually less work than a separate call later. A spare saves you from repeating an all-keys-lost situation, which is always the more involved job.
