What do you do when you have lost all your car keys?
Losing the only key to your car is a stomach-drop moment, and losing all of them is worse, because there is nothing to copy. A duplicate is a simple job when you have a working key in hand. When you do not, the key has to be created from scratch, using information from the vehicle itself. That is what lost car key replacement means, and it is a different job from ordinary copying. If a spare is sitting in a drawer at home, you may only need key duplication instead.
The first thing to do is stay calm and spend two minutes on the likely places. Check the pockets of the jacket you wore, the bottom of your bag, the car seat, and the last counter you stood at. Call the last place you visited. If the keys are truly gone, do not keep paying for a ride around town looking for them. Every hour of searching is an hour the car sits without a key, and an unrecovered key is also a key somebody else may be holding.
One more practical point: if you think the keys were stolen along with a bag or wallet, say so when you call us. A stolen key with your address nearby is a different risk than a key dropped in a parking lot, and it changes what we recommend you do about the car and, sometimes, the locks at home.
How do we make a replacement car key without the original?
There is no single method that fits every vehicle, which is why we start with questions instead of quoting a procedure. The general sequence is the same, though, and it is worth knowing so nothing about the job feels like a mystery. If you want the broader picture of our vehicle work, our automotive locksmith page covers the whole range.
- You call (213) 577-1366. Someone answers any hour of the day or night, and we ask for the year, make, model, and where the car is parked.
- We confirm the details that decide the job: what style of key the vehicle uses, whether it is a push-button start or a turn-key ignition, and whether it can be handled by a locksmith or needs a dealer.
- A mobile technician drives to the car. We do not tow it to a shop unless the situation actually calls for that.
- Before any work, we verify that you own or are authorized to use the vehicle. This is non-negotiable and it protects you as much as anyone.
- We work from the vehicle's VIN and its lock to determine the correct key cut, then cut the new key on the spot.
- If the vehicle requires electronic programming, we program the new key to the car and test it, including starting the engine and checking the locks and any remote functions.
- We hand you the working key, and we talk through whether a spare makes sense before we leave.

Call (213) 577-1366What proof of ownership do you need to bring?
Any honest locksmith will ask you to prove the car is yours before making a key for it. Without that check, anyone could ask for a key to any parked car. It slows nothing down if you have the right items on hand, so gather them while you wait for us.
We will ask for a photo ID and something that links you to the vehicle. Here is what usually works:
- A valid driver's license or state ID
- The vehicle registration or the title
- An insurance card or other paperwork showing your name and the VIN
- For a rental, company, or family-owned vehicle, written permission from the registered owner along with their details
- Your own ID matching the address on the paperwork, or an explanation we can reasonably verify
What kind of key does your car use, and does it change the job?
Yes, a lot. A plain metal key for an older vehicle is cut and tested. A newer vehicle may have a key that also communicates electronically with the car, and in that case the new key must be programmed before the engine will run. Some vehicles use a remote built into the head of the key, and others use a push-button start with a proximity fob and no traditional blade at all. Each type has a different process and a different amount of equipment involved. If your key is a fob, our key fob replacement page explains that side in more detail, and transponder key programming covers how chip keys get matched to a car.
We are careful here, because the details vary by manufacturer, model, and year, and guessing wrong wastes your time. We do not promise that every vehicle can be handled at the roadside. We confirm by VIN and, when needed, in person at the car, before we say what is possible. If your particular vehicle can only be keyed through the dealer, we will tell you honestly instead of pretending, and we will explain what the dealer will likely need from you so the trip is not wasted.
If your problem is not the key itself but the ignition, for instance a key that goes in but will not turn, that is a different repair. We handle it under ignition repair, and it is worth mentioning on the phone so we bring the right tools.
What affects the cost of lost car key replacement?
We do not quote numbers on a web page, because anyone who does is guessing about a car they have never seen. What we can do is tell you exactly what moves the price, so a quote over the phone makes sense when you hear it.
The biggest factor is the type of key. A basic cut key with no electronics is a smaller job than a programmed key, and a programmed proximity fob for a push-button vehicle is a larger job again. The year, make, and model matter because they determine what equipment and software the work needs.
The second factor is how many keys you need. Since we are already at your car with the equipment out, making a spare at the same visit is usually the more economical route compared with having us come back later after you lose the only working key.
Other factors include the time of day, since after-midnight and holiday calls take a technician away from rest, and where the car is parked, because distance and access count. A car in a driveway is a simpler call than one in the back of a locked structure or at the far end of a lot. Finally, if the vehicle needs additional steps, such as a damaged ignition or a lock that has to be worked on first, those are separate tasks and we tell you so before starting.
We give you the full figure before we begin, including anything that could change it, so nothing surprises you at the end.

Call (213) 577-1366Locksmith, dealer, or tow: which route makes sense?
People often assume the dealer is the only option for a lost-all-keys situation. Sometimes it is. Sometimes it is not. Here is how we honestly see it.
A mobile locksmith comes to the car, which matters when the car is in a parking lot, at a curb, or at home and you have no way to drive. You skip the tow and the wait for a service appointment. For many vehicles this is the faster and more economical route, though not for every vehicle and not for every situation.
A dealer can be the right answer for certain makes and models, particularly where the manufacturer restricts the key and security data to its own network. When that applies to your vehicle, we say so, and we do not take your money for something we cannot do. If you go that route, you will likely need to tow or otherwise bring the car in, so the total cost can include that step.
The point is that the answer depends on your vehicle, not on a rule of thumb. A short phone call, with the VIN in hand, usually tells us which way to go. If a locksmith can do it, we come to you. If not, we say so and point you in the right direction.
If the real issue is that the keys are inside the locked car, you do not need a new key at all. That is a car lockout and a much lighter job.
Lost car key replacement around La Puente
La Puente is a compact city, and our mobile vans serve it as part of our work across Los Angeles County. The service area covers both ZIP codes, 91744 and 91746, and the surrounding neighborhoods, including Old Town La Puente, the La Puente Park area, the Hacienda Boulevard corridor, the Amar Road corridor, and the border areas toward Valinda and Bassett. Our storefront is at 10740 Wilshire Blvd in Westwood, which is about 29 miles from La Puente, so the vans come out to you and you do not need to travel to us.
Where you lose a key shapes the call. If you are in the Old Town La Puente business district and realize at the end of a workday that your keys are gone, you are usually standing next to the car, which makes things simple. We come to the curb or the lot, verify ownership, and make the key there. If you work along the Hacienda Boulevard or Amar Road corridors, where commercial lock work is a regular part of the local scene, a lost key often means a work vehicle or a car you need for a shift. Tell us that on the phone so we plan around it, and if the lost key is a business key, we can also look at the building side through our commercial locksmith service.
Near La Puente Park and on the surrounding residential streets, the typical call is different. Many homes in the city are 1950s stucco tract houses with detached garages, and many households share vehicles across several generations of one family. That means a lost car key is often a shared problem: more than one person drives the car, and several people may have a copy of the house key too. When a keyring goes missing with both car and house keys on it, we treat the car first, then talk through whether it makes sense to rekey the locks at home.
The weather matters a little as well. The eastern San Gabriel Valley has hot, dry summers, and waiting beside a parked car in the afternoon sun is miserable. If you are in that situation, tell us. We cannot promise a time on the phone, but we can tell you plainly what we know about the call and keep you updated.

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. Lost-all-keys calls are not a place for improvisation, and decades of experience mean we have seen most of the ways they go wrong. We run a real storefront plus mobile service vans, so there is a physical business behind the phone number, not just a call center.
We are one company. When you call (213) 577-1366, you are not handed to a dispatch middleman who sells the job to whichever stranger is closest. The people who answer work for us, and the technician who arrives is part of the same operation. That makes the quote and the work easier to keep consistent.
The line is answered 24 hours a day, 7 days a week, year-round, because keys do not get lost on business hours. We serve 140 cities across Los Angeles and Ventura counties, and La Puente is one of them.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, which is the state's Bureau of Security and Investigative Services company license. You should ask any locksmith you call for their license number before they start work. Ask us too. Asking is routine, and a company that gets defensive about it is telling you something.
What should you do after you have a new key?
Once the new key works, the job is not quite finished. First, get a spare made and keep it somewhere that is not the same pocket or bag as the main key. A spare is far lighter than a second lost-all-keys call. Our car key replacement page covers the broader picture, including when you simply want an extra.
Second, ask whether the lost keys can still start the car. On some vehicles the old keys can be removed from the car's memory so they no longer work, and on others that is not possible. It depends on the vehicle, and we will tell you which applies to yours. If you suspect theft rather than a simple loss, raise it before we leave.
Third, if the missing keyring had house or business keys on it, think about those locks too. A key with no address attached is low risk. A key that could be matched to your home is a different story, and a rekey is usually a modest step compared with the worry of not knowing who has it.
Finally, consider a simple habit: a dedicated hook by the door, or a second spare held by someone you trust. It is not exciting advice, but it is what actually prevents a repeat of this call.
Frequently asked questions
Can you make a car key if I have lost all of my keys?
Often, yes. We create a new key from the vehicle's information, not from an existing key. The exact process depends on the car's year, make, and model, so we confirm by VIN and in person before saying what is possible. A small number of vehicles are dealer-only, and we tell you honestly if yours is one of them.
Do I need the original key to get a replacement?
No. A replacement car key without the original is exactly what this service is for. If you do have one working key, a simple copy may be the lighter-cost option, so tell us when you call and we will point you to the right one.
Will you come to me in La Puente, or do I have to bring the car?
Our mobile vans come to the car, whether it is in Old Town La Puente, near La Puente Park, along Hacienda Boulevard or Amar Road, or at home. In most cases you do not need to tow the car to a shop. Call (213) 577-1366 and we will confirm the details.
What do I need to prove the car is mine?
A photo ID plus something linking you to the vehicle, such as the registration, title, or insurance paperwork showing the VIN. If you are driving a car owned by someone else, we need written permission from the registered owner. We will not make a key without these checks.
Can I get a new key in the middle of the night?
Our phone line is answered 24 hours a day, 7 days a week, year-round, and we take calls at any hour. The details of a late-night job depend on the vehicle and the location, which we discuss on the phone. After-hours calls can affect the price, and we explain that before we begin.
How much will a lost car key replacement cost?
We do not post prices because they depend on the car. The main factors are the type of key, the vehicle's year, make, and model, how many keys you want, the time of day, and where the car is parked. We give you the complete figure before any work begins.
Should I go to the dealer instead of a locksmith?
It depends on the vehicle. For many cars a mobile locksmith is the more convenient and often more economical route, since there is no tow. For certain makes and models the dealer may be the only option, and we will tell you if yours is one.
If I get a new key, will the lost one still start my car?
That depends on the vehicle. On some cars, lost keys can be erased from the car's memory so they no longer work, and on others that is not possible. Ask us when we are making the new key and we will tell you what applies to your car.
Is a locksmith license required in California?
Yes. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work begins. This applies to us as much as anyone else, and asking is a normal part of hiring a locksmith.
