What happens when you lose all your car keys in Walnut?

Losing one key is an annoyance. Losing all of them is a different problem, because there is nothing left to copy. The spare you meant to make last year is not in the kitchen drawer, the valet key is gone, and the car is sitting in a driveway, a parking lot or a curb with no way to start it. That is the situation this page is about.

The good news is that a missing key does not mean a stuck car. A locksmith with the right equipment can build a working key from the vehicle itself, using the lock, the vehicle identification number (VIN), and the car's own electronics. You do not need the original key, and you do not need to tow the car to a dealer in most cases. What you need is someone who will tell you plainly what your particular vehicle requires before any work starts.

At Wilshire Lock & Key we have been doing this kind of work since 1987. The call usually starts the same way: someone has retraced their steps twice, checked the pockets of yesterday's jeans, and is now looking for a straight answer. We will give you one.

Can you get a replacement car key without the original?

Yes. A replacement car key without the original is the core of this service. It is different from key duplication, where a technician copies a key that already exists. With all keys lost, the new key has to be created from information the car and its paperwork can supply. If you only need a copy of a key you still have, that is a lighter job, and we cover it on our key duplication page.

Creating a key from scratch generally involves two separate tasks. The first is the physical part: producing a blade or key shape that turns the door lock and the ignition. The second, on vehicles that use an electronic anti-theft system, is making the car accept the new key. Those two tasks can be simple or involved depending on the make, model and year.

We do not guess at this over the phone. Some vehicles can be handled entirely at the car. Some need extra steps. A few are dealer-only for key programming, and if yours is one of them we will say so honestly instead of starting work we cannot finish. When we are unsure about a specific vehicle, we confirm by VIN and by looking at the car in person before we promise anything.

How we replace lost car keys, step by step

Here is how a typical lost-all-keys job runs. The details shift by vehicle, but the order is consistent.

  1. Call (213) 577-1366. A person answers at any hour, any day, and asks for the make, model, year and exactly where the car is parked.
  2. Tell us how the keys were lost, if you know. A key lost somewhere you can still search is a different conversation from a key that was stolen along with a bag. If theft is possible, say so, because it changes what we recommend.
  3. We explain the likely route for your vehicle, what we will need to see, and what affects the final cost. If your car looks like a dealer-only case, we say that now.
  4. A technician comes to the car in one of our mobile vans. If the car is not drivable or is locked, we work at its location.
  5. We verify ownership, which means ID and proof the vehicle is yours. We read the VIN from the car and match it to your paperwork.
  6. We get into the car if it is locked, then produce the new key and, where the vehicle needs it, program it so the car starts.
  7. We test the new key in the door, the ignition and any remote functions before we leave. If you want a second key made while we are there, that is far easier now than later.

What do we need from you?

Making a working key for a car is a security-sensitive job, so we do not skip the paperwork. It protects you as much as anyone. A technician who would cut a key for any stranger standing next to any car is a technician you should not hire.

Have the following ready when you can. If you are missing something, call anyway and we will tell you what is workable.

  • A government-issued photo ID that matches the name on the vehicle's registration or title
  • Current registration, title, or other proof that the car is yours
  • The VIN, visible through the windshield on the driver's side dashboard and printed on your registration
  • The vehicle's make, model and year, plus any details about the key you remember, such as whether it had a remote or a push-button start
  • The car's exact location, including the level or space number if it is in a parking structure

How much does lost car key replacement cost in Walnut?

We do not quote numbers on a web page, because an honest number depends on the car. What we can do is tell you exactly what moves the cost up or down, so the quote you get on the phone makes sense.

Vehicle make, model and year matter most. Some keys are a plain cut piece of metal. Others contain electronics that must be matched to the car, and those take more equipment, more time and more expensive key blanks. A newer push-button-start vehicle with a smart key is a different job from an older car with a basic ignition key.

Other factors include whether the car is locked and we have to get in first, whether the ignition or locks are worn or damaged, how many keys you want made, and whether a remote fob is part of the package. Time of day and your location also play a role, because a night or holiday call-out and a longer drive both take real resources. If you are curious how remotes and fobs affect the work, see our page on key fob replacement.

Our approach is to give you a clear explanation of the likely cost range for your situation before the van heads your way, and to confirm it once the technician has seen the vehicle. If the job turns out to need something different from what we expected, we tell you before continuing, not after.

Locksmith or dealer: which route fits your car?

Dealers can replace lost keys, and for some vehicles they are the only option. A locksmith is often the more economical route, and usually the more convenient one, because we come to the car. You do not have to arrange a tow, and you do not have to work around dealership service hours.

The honest comparison is this. A mobile locksmith is typically the practical choice when the car is stuck somewhere inconvenient, when you need it running the same day, or when you want a spare made on the spot. The dealer route makes sense when your specific vehicle is dealer-only for programming, or when you would rather have the manufacturer handle it. We would rather tell you that up front than have you pay for a visit that cannot solve the problem.

If you are not sure which side your vehicle falls on, give us the VIN and we will tell you what we can and cannot do. Our car key replacement page goes into the wider range of key jobs, and transponder key programming explains the electronic side in more detail.

Why call Wilshire Lock & Key for lost car keys?

There are a lot of listings that look like local locksmiths and are really call centers that forward the job to whoever is available. We are not that. Here is what you actually get when you call us.

  • In business since 1987, so this is not a side service we picked up recently
  • A storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so there is a real shop behind the van that shows up
  • One company, no dispatch middlemen, so the person who explains the job is part of the company that does it
  • David, the owner and lead technician, oversees the work, and his name is on the business
  • Phone answered 24 hours a day, 7 days a week, year-round, because lost keys do not keep office hours
  • We serve 140 cities across Los Angeles and Ventura counties, including Walnut

Lost car key replacement around Walnut

Walnut sits in the eastern San Gabriel Valley, with a single ZIP code, 91789. The city is mostly 1970s-1990s single-family tracts on hillside lots, many of them in HOA communities, and most households own their homes. That matters for cars, because most vehicles are parked in driveways and garages rather than in big shared lots. When all keys are lost in a neighborhood like the Snow Creek area, Lemon Creek area or Walnut Hills, the car is usually right there at the house, which makes a mobile visit simple. We work at the vehicle, in the driveway, and you do not need to move anything.

Walnut is also home to Mt. San Antonio College, and the Mt. SAC campus area has its own pattern. Student vehicles get parked for long stretches in campus lots and nearby streets, and a backpack that goes missing between classes can take a student's only key with it. Many students have never had a spare made, so a lost key often means all keys lost. If that is your situation, call, and have the VIN and your registration ready. If the car is in a student's name and the registration is in a parent's, tell us up front so we can explain what ownership documentation we need.

Along the Amar Road corridor, the Grand Avenue corridor and the north edge of Valley Boulevard, the situation is often a work vehicle or a car parked at a shop or office. The car may be locked in a parking lot with the only key gone for the day. If your car is locked and you still have the key somewhere, you may only need our car lockout service instead. For a true lost-everything situation, we handle getting in and making the new key as part of one visit.

Walnut's hot inland-valley summers deserve a practical word. Waiting beside a locked car for a key to arrive is not pleasant in a heat wave, and the south Walnut hills near the Brea Canyon Cutoff can be exposed. If you are out near Snow Creek Park, Lemon Creek Park, Suzanne Park or Walnut Ranch Park with a lost key, wait in the shade or in a nearby building while we come to you, and tell us your cross streets when you call.

One honest note about distance. Our storefront is in Westwood, and Walnut is a real drive from there. We will tell you the arrival window when you call and update you if anything changes, rather than give you a number that sounds good. For more on how our vans reach customers across the county, see our mobile locksmith page.

What to do before you call us

A few minutes of looking can save you the cost of a call-out, and a few other steps keep a bad day from getting worse. None of this is complicated.

  • Search the obvious places once more: coat pockets, the car's own cup holders, the last place you paid, a friend's car or house
  • Check whether anyone else in the household has a spare, including a valet key tucked in a drawer
  • If you think the keys were stolen, think about whether your address or the vehicle registration was also in the bag, and consider reporting it
  • Take a photo of the VIN and your registration so you have both ready when you call
  • Do not try to force the door or ignition. Damage to the lock or steering column makes the job longer and the cost higher
  • If a key is broken off in the ignition or door rather than lost, that is a separate fix, covered by our broken key extraction service, and sometimes an ignition repair job

Should you ask for a license number?

Yes, from any locksmith. California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. It is a reasonable question to ask when someone is about to make a key to your car, because that key gives access to a vehicle worth thousands of dollars. Ask for the license number and the company's actual name, and be wary of anyone who dodges the question or answers the phone with a generic greeting that does not name a business.

When you are ready to talk, you can reach us through our contact page or just call (213) 577-1366. We would rather answer questions before the van rolls than have you guess.

Frequently asked questions

Can you make a car key if I have lost all my keys?

Yes. We make new keys from scratch using your vehicle, its VIN and your proof of ownership. You do not need the original key. The exact process depends on your make, model and year, and we confirm by VIN and in person whether it can be done at the car or is dealer-only.

Do I need to tow my car to get a replacement key?

Usually not. Our mobile vans come to the vehicle, whether it is in a driveway, a campus lot or on a street. The exception is a vehicle that turns out to be a dealer-only case. We tell you that early so you do not pay for a visit that cannot finish the job.

What proof of ownership do you need?

We need a photo ID that matches the name on the registration or title, plus the registration or title itself. We also read the VIN from the car and match it to your paperwork. This protects you and keeps us from making a key for someone who does not own the vehicle.

How long does lost car key replacement take?

It depends on the vehicle and how much programming it needs. A simple key can be quick, while a more involved vehicle takes longer. We do not quote a time on this page, but when you call we give you a realistic arrival window and an idea of how long the work should take.

Will the new key work the same as my original?

The goal is a key that opens the doors and starts the car, and where your vehicle supports it, one that also runs remote functions. We test everything before we leave. If you want a remote fob as well, see our transponder key programming page for how electronic keys are matched to a car.

What if my car is locked and the keys are inside?

That is a lockout, not a lost-key job, and it is a lighter fix. We can get you in without making a new key. If the keys are truly gone and the car is locked, we get in first and then handle the key replacement in the same visit.

Should I get a spare made after replacement?

Yes. Once we have one working key, making a second is far easier than starting from nothing again. Ask while the technician is there. A spare kept somewhere safe at home is the single best protection against another lost-all-keys situation.

Are you available at night and on weekends in Walnut?

Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, including holidays. We serve Walnut and 140 cities across Los Angeles and Ventura counties, and we will give you an arrival window when you call.
