What happens when you have lost all your car keys?
Losing one key is an annoyance. Losing all of them is a different problem, because there is nothing left to copy. A basic duplicate works by tracing an existing key and, on most modern cars, cloning or pairing an electronic signal that already exists. When there is no working key at all, the new key has to be created from the vehicle itself: the cut is worked out from the car's lock information, and the electronics are programmed to the car so it will start.
That is what lost car key replacement means, and it is a separate job from ordinary duplication. If you still have one working key, you want key duplication instead, and it is usually the simpler route. If you have none, a replacement car key without the original is the path, and it is exactly what we do from our vans.
The first thing worth saying plainly: this is solvable in most cases, but not every vehicle behaves the same. Some cars accept a new key from a locksmith on site. Some need extra steps. A small number of makes and models can only have new keys created through the dealer. We tell you which situation you are in before any work starts, and we do not guess about it over the phone.
How does a replacement car key without the original get made?
The process is the same in broad strokes for most vehicles, though the details change with the make, model, and year. Here is how a typical visit goes.
- You call (213) 577-1366. Someone answers at any hour, any day. We ask where the car is, the make, model, and year, and whether you have any key, fob, or valet card at all.
- We send a mobile van to the car. If the vehicle can be reached where it sits, we work there, so it does not need to be towed first.
- We confirm ownership. This means a photo ID and something tying you to the vehicle, covered in the next section. We do not skip this step, and a legitimate locksmith should not either.
- We identify the vehicle exactly, usually by VIN and by checking the car in person. This is how we confirm what kind of key and what kind of chip or system it uses, rather than relying on a general chart.
- If the doors are locked, we open the car without damage. If it is already open, we move straight on.
- We cut a new key to fit the locks, then program the electronics so the car recognizes it. For push-button start cars, this means pairing a new fob or smart key.
- We test everything: door locks, trunk, ignition or start button, and remote functions where they apply. You do not sign off until the key does what it should.

Call (213) 577-1366What do you need to prove the car is yours?
A locksmith who makes keys for a car without asking whose car it is would be making keys for anybody who walks up. We ask every time, and the reason is the same one that protects you if someone ever tried it on your car.
- A government-issued photo ID that matches the name on the paperwork.
- Registration or title showing the vehicle, or a lease or rental agreement if the car is not in your name.
- The VIN, which we can read from the dashboard plate or the door jamb sticker if you are standing at the car.
- If the car belongs to someone else, such as a parent, an employer, or a roommate, call us first and we will explain what is needed so you are not stuck at the curb.
Locksmith or dealer: which route fits a lost car key?
People assume the dealer is the only official way to get a key made after all keys are lost. For many vehicles that is not true, and the dealer route often involves towing the car there and waiting on their schedule. A mobile locksmith comes to the car, which removes the tow from the picture on vehicles we can handle on site.
We will be honest about the other side too. Some vehicles are dealer-only for new keys, or need a code, a part, or equipment that is only available through the manufacturer. Certain newer or higher-security systems fall into that group. When that applies to your car, we say so right away instead of letting you pay for a visit that cannot finish the job, and we point you toward the right next step.
Because chip and programming details vary and sometimes conflict between sources for the same model, we confirm by VIN and in person rather than quoting a general rule. If you want to know how we think about the broader category, our automotive locksmith page covers the range of vehicle work, and the car key replacement page covers replacements when a key exists but needs to be remade.
What affects the cost of lost car key replacement?
We do not publish numbers on this page because the honest answer is that cost depends on the car, and a flat figure would be wrong for many people reading it. Here is what moves the price up or down, so you can judge any quote you receive, ours or anyone else's.
Call us with the make, model, and year and we can describe the situation more precisely. Where a firm figure needs the VIN or a look at the car, we say that rather than invent one.
- The type of key. A plain mechanical key, a transponder key with a chip, a remote-head key, a flip key, and a push-button smart key are very different items with different parts and programming needs.
- The vehicle's system. Some cars are straightforward to program on site. Others require additional steps or more specialized equipment, which affects time and cost.
- Whether the doors are locked. If we have to open the car first, that is part of the visit, though it is a task we do routinely. See our car lockout service for that part on its own.
- The number of keys. Having us make a second key while we are there is usually the more economical route compared with coming back later, and it spares you the next emergency.
- Time and place. After-hours or hard-to-reach locations take more of the van's time than a daytime visit in a driveway.
- Any damage found. If the ignition or a lock is worn or broken, that is a separate repair. See ignition repair if that turns out to be the real issue.

Call (213) 577-1366Lost car keys in Azusa: where it actually happens
Azusa is about 35 miles from our Westwood storefront at 10740 Wilshire Blvd, which is why we run mobile vans rather than asking you to come to us. The vans are how a lost key call in the 91702 ZIP code gets handled, whether the car is in a driveway, on a street, or in a parking structure.
Some of the situations that fit this city are worth describing, because lost keys do not happen in the abstract. They happen where people live and park.
Near Azusa Pacific University and the University District, cars are parked on streets and in apartment lots by people who share keys, lend cars, and move often. A student who loses the only key to a car, or a roommate who walks off with it, is a common version of this call. Ownership paperwork matters here, because the car may be registered to a parent in another city. If that is you, tell us when you call and we will walk through what is acceptable.
In Rosedale, a master-planned community built out since the mid-2000s, many households have newer vehicles with smart keys and push-button start. That tends to mean a fob or smart key rather than a simple cut key, and we confirm what the car needs by VIN before anything else. Rosedale garages and driveways are easy places to work on a car in place.
The Azusa Downtown and APU/Citrus College A Line stations have park-and-rides, and that creates a particular scenario: someone leaves a car there, rides the train, and comes back to find the keys gone. The car is locked, the keys are somewhere along the line, and it is not safe to leave it overnight without a plan. We can open the car and make a new key on site, so you are not arranging a tow from a station lot.
In Mountain Cove, the gated community at the mouth of San Gabriel Canyon, access is the first step. Give us the gate details when you call so the van can get in. Along the SR-39 gateway, Azusa Avenue, the Gladstone Street corridor, and the Arrow Highway corridor, cars are often left curbside or in business lots, and we meet you wherever the car is.
One regional note from the data we have: Santa Ana winds funnel through the canyon mouth, and the summers are hot and dry. That is not a reason keys go missing, but it is a reason to check the ground, planters, and car interior carefully before you decide the keys are truly gone. Keys dropped outdoors can end up in strange places.

We answer around the clock, every day of the year.
Call (213) 577-1366What should you do before you call?
A few minutes of checking can save you a visit, and a few mistakes can make the job harder. This is how we would approach it if the car were ours.
- Retrace your steps and check pockets, bags, jackets, and the place you last parked. Keys are more often misplaced than gone for good.
- Look for a spare. A spare key at home, with a family member, or with a roommate would change the job entirely, and a duplicate is a lighter job than starting from nothing.
- Check whether the key might be inside the car. If the car is locked with the key inside, that is a lockout, not a lost key situation, and it is a simpler fix.
- Do not try to force the ignition, pry at the door, or push a tool into the lock. That is how a lost key problem becomes an ignition or door damage problem.
- Have the make, model, year, and your ID ready when you call. If you can read the VIN from the dashboard, even better.
- If the key broke off in a lock or ignition, say so. That is a different job, and our broken key extraction service covers it.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987. That is long enough to have worked on a lot of cars and to have seen the change from simple metal keys to chips, fobs, and push-button systems. David, the owner and lead technician, oversees how we handle these jobs, and that matters on lost key calls where the details are easy to get wrong.
We are one company with a storefront in Westwood and our own mobile vans. There is no dispatch middleman who takes your call and hands it to a stranger. The person who answers works for the same business that sends the van, and the phone is answered around the clock, every day of the year, at (213) 577-1366. If you want to see how our coverage works in the city, our mobile locksmith page explains it, and the 24-hour locksmith page covers the late-night side.
One more point worth making. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. Ask any locksmith you call for that license number, including us. It is a fair question, and a company that avoids it is giving you information too.

Call (213) 577-1366What about the old key and the rest of the car after replacement?
Once a new key works, there is one loose end: the lost key is still out there. If it was lost in a place where a stranger could connect it to your car, that is worth thinking about. On some vehicles, the programming process can be set up so that previously known keys no longer start the car. That depends on the vehicle, and we confirm what is possible on your specific car rather than promising it in general.
If the loss also involved a house key on the same ring, the car key replacement is only half of the problem. Keys that went missing with your address on a registration or in a bag are worth treating seriously, and you may want to look at lock rekey work at home too. We would rather mention that than leave it unsaid.
Finally, make a spare while we are there, if it makes sense for your car. Getting a second key made in the same visit usually costs less overall than starting from nothing again later, and it means the next lost key is just an inconvenience. If the vehicle uses a remote, our key fob replacement and transponder key programming pages describe those parts of the work in more detail.
Frequently asked questions
Can you make a car key in Azusa if I have no original key at all?
Yes, in most cases. We create a new key from the vehicle itself, cutting it to fit and programming it to the car. The one caution is that a small number of makes and models are dealer-only for new keys. We confirm by VIN and in person, and if your car falls into that group we tell you plainly.
Do I have to tow my car to a dealer if I lost all my keys?
Often you do not. Our vans come to the car, so on vehicles we can handle on site there is no tow. If your specific vehicle can only be keyed through the dealer, we say so up front so you do not pay for a visit that cannot be completed.
What do I need to show you to prove the car is mine?
A government photo ID and something tying you to the vehicle, such as registration, title, or a lease agreement. We also use the VIN. We ask every time because it protects you as much as it protects the car.
How much does a lost car key replacement cost?
It depends on the type of key, the vehicle's system, whether the doors need to be opened first, how many keys you want, and where and when the visit happens. We do not quote numbers on this page because they would be wrong for many cars. Call (213) 577-1366 with your make, model, and year and we will explain what applies to yours.
I left my car at an A Line station in Azusa and lost the keys. Can you help?
Yes. We can come to the park-and-ride, open the car if it is locked, and make a new key on site. Tell us which station and where in the lot the car is parked, plus have your ID and vehicle details ready.
Can you make a key for a car registered to someone else, like a parent?
Possibly, but it depends on the paperwork. We need proof of ownership or authorization tied to the vehicle. Call us before the visit and we will explain what is acceptable so you are not stuck at the car with the wrong documents.
Will the lost key still start my car after you make a new one?
On some vehicles the programming can be arranged so earlier keys no longer start the car, but this varies by make and model. We confirm what is possible on your car when we identify it by VIN, rather than promising it in advance.
Do you work at night and on weekends in Azusa?
Yes. Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, and our mobile vans serve Azusa, including the 91702 ZIP code, at any hour.
Should I get a spare key made at the same time?
Usually yes, if the car allows it. Having a second key made during the same visit is typically the more economical route compared with another emergency call later, and it keeps one lost key from becoming a full lockout again.
