What do you do when you've lost all your car keys?
Losing every key to your car is a different problem from losing one of two. With a spare in a drawer, you can get moving, and a copy is a simple job. With no key at all, nothing in your hands tells the car you're the owner, so the work becomes making a brand-new key from scratch and getting the car to accept it. That is lost car key replacement, and a locksmith with the right equipment can often do it right where the car sits, without towing it anywhere.
Before you call, check the usual places. Look at the jacket you wore last night, the gap beside the car seat, the bottom of a gym bag, and the last counter where you paid for something. Small fobs slip into cushions and coat linings more often than people expect. If you've honestly looked and the key is gone, stop searching and start the replacement, because every hour you spend hunting is an hour the car is stuck.
One more thing worth saying on the call: tell us whether you think the key was lost or stolen. A key that fell out of a pocket is an inconvenience. A key that someone took, especially if the registration or a garage remote was nearby, is a security question, and we'll talk through what else needs attention.
Can you get a replacement car key without the original?
Yes. A replacement car key without the original is a normal part of automotive locksmith work. We don't need the old key as a pattern. The cutting information comes from the vehicle itself, identified by its VIN, and the blade can often be cut by code or by reading the lock. If the car uses a transponder chip or a proximity fob, the new key must also be programmed so the car's computer recognizes it and lets the engine start.
How that goes depends on the make, model, and year, and I won't pretend one answer fits every car. Some vehicles let us add a key with diagnostic equipment at the curb. Others put programming behind manufacturer security that only the dealer can open, or need a longer procedure. That's why we confirm by VIN and by looking at the car in person instead of guessing over the phone. If yours turns out to be a dealer-only case, we tell you so before any work starts.
The programming side is covered in more detail on our transponder key programming page. If your key is a push-button remote or proximity fob, the page on key fob replacement explains what's different about those.

Call (213) 577-1366How does a lost-all-keys call work, step by step?
Here is how these calls normally go. The details shift with the car, but the order stays the same.
- You call (213) 577-1366. Someone answers at any hour, any day. Give us the make, model, year, and exactly where the car is parked.
- We ask what kind of key the car used: a plain metal key, a plastic-headed key with a chip, a flip key, or a push-to-start fob. If you don't know, say so. We'll work it out from the VIN.
- We confirm the car is yours before cutting anything. That means ID and proof of ownership, covered in the next section.
- We come to the car with a mobile locksmith van. Most lost-key jobs are done where the car is sitting. If the car can be moved or towed, our Westwood storefront is also an option.
- We identify the key by VIN, cut the blade, and prepare the transponder or fob that matches your vehicle.
- We program the new key to the car, then test it properly: start the engine, lock and unlock, open the trunk, and try any remote buttons.
- Before we leave, we talk about a spare. Making a second key while we're already there is usually the more economical route compared with a second lost-key call later.
What do you need to prove the car is yours?
Any honest locksmith will ask this, because a locksmith who makes a key for any stranger who asks is a risk to every car owner, including you. We ask for the same thing every time, and it only takes a moment.
Have these ready if you can:
- A photo ID, such as a driver's license, that matches the name on the registration.
- The registration or title for the vehicle, or another document that ties you to the car.
- The VIN, which is on the registration and usually visible at the base of the windshield on the driver's side.
- If the car is leased, company-owned, or registered to a family member, paperwork or authorization from the owner or lessor.
What affects the cost of lost car key replacement in Sherman Oaks?
I won't quote you a number in a web page, because the honest answer is that it depends on the car. Here is what moves the cost up or down, so you can see why two calls can come out differently:
- The type of key. A plain cut key, a chipped key, a flip key, and a smart proximity fob are very different pieces of hardware.
- The vehicle's make, model, and year. This decides how the key is identified, what equipment is needed, and how involved the programming is.
- How many keys you need. Each extra key adds parts and programming time, but making a spare during the same visit is usually the lighter-cost way to get one.
- Whether the car's security allows programming at the curb. If it doesn't, extra steps or the dealer may be needed.
- Whether the car has to be moved. A car that can be reached where it sits is simpler than one in a locked structure, or one that must be towed.
- The hour you call. We answer around the clock, and middle-of-the-night work is a different request from a weekday visit.
- Whether anything else is damaged, such as a worn ignition or a broken key stuck in a lock, which is separate work.

Call (213) 577-1366When is the dealer the only option for a lost car key?
Sometimes it is, and we'd rather say so than waste your time. Certain vehicles keep their key programming locked behind manufacturer-only systems, and on those a locksmith can't finish the job no matter how good the equipment is. Other cars can be handled by a locksmith but may need a part that has to be ordered. We confirm which case you're in by VIN and in person rather than promising something over the phone.
When the dealer is the right call, we tell you before any work begins. When a locksmith can do it, mobile service often removes the towing step, which is a real advantage when the car is parked and you're not. Neither route is right for every car, and I'd rather you get the right one than the one that suits us.
One more tip. California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith you call for that license number before work starts. It's a fair question, and a reputable company will answer it without fuss.
Lost car key replacement around Sherman Oaks
Sherman Oaks is about 8 miles from our storefront at 10740 Wilshire Blvd in Westwood, and our vans work across ZIP codes 91403, 91423, 91401, and 91411. Where you've parked matters more here than in many neighborhoods, so here is how it usually plays out.
Along the Ventura Boulevard corridor, many people live in HOA-managed condo buildings from the 1960s through the 80s, and the condo and apartment stock also runs along Sepulveda and Riverside. If your car sits in a building garage and your keys are gone, tell us the building name and any access rules on the call. Gate codes, guest procedures, or a manager's approval can all affect how we get to the car, and it's easier to sort that out first than at the garage door.
The hillsides south of Ventura, including the Mulholland corridor, Longridge Estates, and Royal Woods, have gated properties, side-yard doors, and multiple entry points. If your car keys were on the same ring as your gate remote or house key, replacing the car key is only part of the job. You may want to look at lock rekeying for the house once the car is sorted, especially if you suspect the keys were taken rather than dropped.
Closer to Westfield Fashion Square, the Galleria district, and the Magnolia Boulevard corridor, the story is usually simpler: you shopped, ate, or worked, and when you got back to the car, the key wasn't in your pocket. If that's you, retrace your steps once, then call. In valley summer heat, sitting in a parked car with no key is more than an inconvenience, and we'd rather you not wait it out.
Wherever you are, give us the cross streets or a landmark such as the Ventura and Sepulveda intersection or the I-405 and US-101 interchange area, and we'll take it from there.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
We've been in business since 1987, and David, the owner and lead technician, oversees our work. When you call, you reach our company, not a call center that sells your job to whoever picks it up. That matters on a lost-key call, because the person who knows your situation is the person who arrives.
We run a storefront in Westwood plus mobile vans, and we serve 140 cities across Los Angeles and Ventura counties. Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, all year. If you'd like to understand how our late-night work runs, see our 24-hour locksmith page.
We also tell you when we can't do something. If your car needs the dealer, you'll hear that from us first, not after we've wasted your afternoon.
Is the key really lost, or is it a different problem?
Not every no-key situation is a lost-all-keys job, and the right fix depends on what's actually wrong. If the key is simply locked inside the car, that's a car lockout, which is usually a lighter job than making a key from scratch. If you have a key but the car won't recognize it or the ignition won't turn, the problem may be in the ignition itself, and our ignition repair page explains that.
If you have a broken key with part of it still in the lock, don't force it. Call us and we'll sort out what's stuck and what, if anything, needs replacing. For the full picture of how we handle new keys, you can also read about car key replacement in Sherman Oaks, and if you're still unsure which situation you're in, call and describe it. We'll tell you straight.
Frequently asked questions
Can you make a car key if I have no key at all?
Yes. We make new keys from scratch using your VIN, then cut and program them to the car. We confirm the exact method by VIN and in person, because some vehicles need dealer-only steps, and we tell you that before work starts.
Do I need to tow my car to get a new key?
Often not. Our mobile vans do most lost-key work where the car is parked. Whether towing is needed depends on the vehicle's security system, and we confirm that by VIN and by looking at the car.
How long does a lost car key replacement take?
It varies with the vehicle and key type, so I won't promise a time. When you call (213) 577-1366 with the make, model, and year, we'll tell you what the job involves and give you a realistic idea of the timing.
What do I need to show to prove the car is mine?
A photo ID that matches the registration, plus the registration or title. The VIN helps. For leased, company, or family-registered cars, we may need paperwork from the owner or lessor.
Will my lost key still start the car after you make a new one?
It depends on the vehicle. On some cars, lost keys can be removed from the car's memory so they no longer work, but that isn't true everywhere. We confirm what's possible for your car by VIN before we start.
Can you come to my condo building garage in Sherman Oaks?
Yes, we serve Sherman Oaks condo buildings, including those along Ventura Boulevard. Tell us the building name and any gate or HOA access rules when you call so we can plan how to reach the car.
Is the dealer cheaper than a locksmith for a lost key?
It depends on the car, the key type, and whether towing is involved. A mobile locksmith can remove the towing step on many vehicles, but some cars truly need the dealer. We explain which applies to you.
Should I get a spare key while you're already there?
Usually yes. Making a second key during the same visit is generally the more economical route compared with having someone come out again after the next lost key. Ask about it on the call.
I lost my keys near Westfield Fashion Square. Should I keep searching?
Retrace your steps once and check with the venue or lost-and-found. If the key doesn't turn up, call us rather than keep searching. If you think it was stolen, tell us, because that affects what else you should secure.
