What does it mean when you have lost all your car keys?
When you have lost all your car keys, there is no spare in a kitchen drawer and no original to copy. That changes the job. A normal duplicate is a copy of something you are holding. A replacement car key without the original is built from information instead: the vehicle identification number, the key code or lock data for that car, and the security information stored in the vehicle's computer.
Most keys made in the last couple of decades have two parts. One is the metal blade, which turns the locks and sometimes the ignition. The other is electronic, either a transponder chip inside the head of the key or a smart-key circuit in a fob. The car has to recognize that electronic part before it will start. So cutting a blade is only half the work. The new key also has to be introduced to the car and accepted.
People end up in this spot in ordinary ways. A key ring slips out of a bag at a park, a jacket gets left somewhere, a valet or a family member turns out not to have the spare after all, or the one key you had simply disappears between the car and the front door. Whatever the reason, the goal is the same: get you a working key, and make sure the lost one is no longer a problem for you where the car allows it.
How do we make a replacement car key without the original?
The exact method depends on the make, model and year, but the process follows the same general path every time. We are open about it because you should understand what is happening to your car.
- You call (213) 577-1366 and tell us the make, model, year and where the car is. Day or night, a person answers.
- We ask for the VIN, which is usually visible through the windshield at the driver's side dashboard corner and also on your registration or insurance card. The VIN lets us confirm what kind of key and system your car actually uses instead of guessing.
- We confirm that you are the owner or authorized to have the key made. Expect to show photo ID and something tying you to the vehicle, such as registration or title paperwork.
- Our technician comes to the car in a mobile van, or you bring the car to our Westwood storefront if that suits you better. If the car is locked, we open it first without damage.
- The key blade is cut from the lock's data or the VIN-derived code, not from an old key. If the car has a door lock or ignition that is worn, we may need to adjust the cutting so the key actually turns smoothly.
- We program the electronic part so the car accepts it, and we test every function: door locks, trunk, ignition and start. If the vehicle supports removing the lost key from memory, we talk with you about doing that.
- You get your keys in hand, and we explain anything unusual about your particular vehicle before we leave.

Call (213) 577-1366Can every car be handled on the spot, or does it need the dealer?
Honestly, no, not every car. Most common vehicles can be handled in the field by a locksmith with the right equipment. Some vehicles, particularly certain newer models and some European makes, can lock out aftermarket programming or require access codes that are only available through the dealer or the manufacturer. We do not know that for your car until we have the VIN and, in some cases, have looked at the vehicle in person.
What we will not do is promise something and then change the story when we arrive. When you call, we tell you what we can confirm over the phone, what we need to verify by VIN or at the car, and if your vehicle looks like a dealer-only case, we say so plainly so you do not waste time or money waiting on us. If a dealer is the right answer, we would rather tell you that than start a job we cannot finish.

What affects the cost of lost car key replacement in Porter Ranch?
We do not quote prices in a web page because two cars that look similar can need very different work. 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.
The biggest factor is the type of key your car uses. A plain metal key is a small job. A key with a transponder chip is more. A proximity fob or push-to-start smart key, with its own circuitry and encrypted pairing, is more again. The more security built into the system, the more equipment and time the work takes.
Make, model and year matter because manufacturers handle key data differently. Some cars let us generate and pair a key on site with standard tools. Others need extra steps, special software access, or a part that has to be ordered. That is why we ask for the VIN before we say anything firm.
- Key type: basic blade, transponder key, remote head key, flip key, or smart fob.
- Vehicle make, model and year, and how that manufacturer protects its key data.
- Whether the car is locked and needs to be opened first.
- Whether the ignition or door lock is worn and affects cutting or turning.
- How many keys you want made. Making a second key during the same visit is usually the more economical route compared with coming back later.
- Whether you want the lost key erased from the car's memory, where the car supports that.
- Where the car is, and whether we come to you or you bring it to the storefront.
- The time of day, since night and holiday calls take people away from their families and normal schedules.

Call (213) 577-1366What should you do before you call?
A few minutes of preparation makes the call quicker and the quote more accurate. None of it is complicated.
First, look once more in the obvious places, including the last place the car was started, jacket pockets, and any bag you carried. Check whether a family member has a spare. If a key turns up, it may save you the job. If you are sure all keys are gone and you left them somewhere public, you may also want to leave your phone number with that location in case someone turns them in.
- Write down the make, model, year and color of the car.
- Have the VIN ready. It is on the dashboard corner by the windshield and on your registration or insurance card.
- Have photo ID and proof of ownership ready, such as registration, title or an insurance card with your name.
- Know exactly where the car is parked and whether it is in a gated or guard-gated area.
- Tell us if the car is locked, and whether your phone or any app has a digital key you can still use.
- If the car is locked and you only need to get inside while you search for your keys, that is a separate job. See car lockout help in Porter Ranch.
What does lost car key replacement look like around Porter Ranch?
Porter Ranch is a master-planned community of larger two-story homes, built in phases from the late 1980s through ongoing new construction. Most streets sit inside HOA-governed villages, and many are gated or guard-gated. That shapes how a lost-key call works here more than it would on an open street.
If your car is parked at home in Porter Ranch Estates, Renaissance, Canyon Oaks or Avila, the gate matters. Westcliffe and Hillcrest are guard-gated, which means our technician will need to be announced at the guard house, so give us your name, address and the gate contact when you call, and let the guard know to expect us. In a village with a pedestrian or vehicle gate that needs a code, tell us the code or arrange for someone to let the van in. These small details are the difference between a smooth visit and a van waiting at a closed gate.
Plenty of lost-key calls here do not start at home. The Vineyards at Porter Ranch and Porter Ranch Town Center are busy retail areas along the Sesnon Boulevard corridor, and a set of keys left on a restaurant table or dropped in a parking space can leave a car stranded in a lot. Keys also go missing around Holleigh Bernson Memorial Park, Limekiln Canyon Park and Porter Ridge Park, where people walk, play and leave bags on benches. In any of those cases our mobile service can come to the vehicle in the 91326 ZIP code, so you do not need to arrange a tow just to start the process.
One more local point: many Porter Ranch households keep the car key on the same ring as the house key, and newer homes here often have builder-installed keypads and smart locks. If your whole ring is gone, the car is only one concern. Ask us about rekeying afterward, since a lost ring with your address attached to it is worth taking seriously. Our lock rekeying service is the follow-up many people choose.
Our storefront is at 10740 Wilshire Blvd in Westwood, about 25 miles from Porter Ranch, so we tell you when you call exactly how we plan to get to you, rather than leaving you to guess.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and that history is mostly a long list of cars with nothing left to copy and owners who needed to get home. We are one company with a storefront and our own mobile vans, not a call center that passes your job to whichever contractor picks it up. The person who answers is part of the same operation that sends the van.
David, the owner and lead technician, oversees the work. When a car has an unusual system or a job needs a second opinion, that goes through him. We would rather take a few extra minutes to confirm your vehicle than start something we cannot finish.
Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, because lost keys do not follow business hours. We serve 140 cities across Los Angeles and Ventura counties, and Porter Ranch is one of them. For help beyond keys alone, our mobile locksmith service page explains how our vans work in the area.
How do you check that a locksmith is legitimate?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), called a Locksmith Company (LCO) license. Whoever you call, ask for the company's license number and for the name of the technician who is coming. A legitimate business will give you both without hesitation.
Other signs are practical ones. They should ask for your VIN and proof of ownership before making a key. They should be willing to describe the process and tell you what is uncertain about your vehicle. They should be able to explain what affects the price instead of giving a vague promise on the phone and a different number at your car door. If something feels off, you can end the call and try someone else.
Asking for ID before making a key can feel like an inconvenience, but it protects you. A locksmith who will make a car key for anyone with no questions is a risk to every car owner.
How do you avoid ending up with no keys again?
Once you have a working key, the best thing you can do is not be down to one again. Ask for a spare to be made during the same visit if the car allows it, and keep it somewhere that is not the car, not your bag and not the same ring as your daily key. A trusted family member's home or a secure spot in your own house works better than a magnetic box under the bumper.
If the car you drive still has one working key, copying it is typically simpler than starting from nothing. Our key duplication service covers that, and doing it before the last key goes missing is the most economical way to stay out of this situation. If you only have the metal part of a key and the remote is the problem, that is a different job from a full lost-key replacement.
Frequently asked questions
Can you really make a car key if I have lost every key?
In most cases, yes. We make the key from the VIN, lock data or key code and then program the electronic part so the car accepts it. Some vehicles, particularly certain newer or European models, may be dealer-only or need extra steps. We confirm by VIN and, if needed, in person, and we tell you plainly before starting if your car is one of those.
Do I need to have my car towed to you?
Often not. Our mobile vans can come to the car in Porter Ranch and do the work where it is parked. If your vehicle turns out to need equipment or access that only works at a shop or dealer, we will tell you before anything happens so you can decide.
What do I need to show to prove the car is mine?
Photo ID and something that ties you to the vehicle, such as your registration, title or an insurance card with your name on it. We also ask for the VIN. We do this for every key, because it protects you as much as us.
Will the key I lost still start my car if someone finds it?
It might. A lost key stays in the car's memory unless it is erased. When the vehicle supports it, we can remove old keys during programming so only the new ones work. Ask us about this when you call, since it depends on the make, model and year.
Is a locksmith or the dealer the better choice for a lost car key?
For many vehicles a locksmith is the more economical route, and we can come to you instead of you arranging a tow. But some cars can only be handled by the dealer. We can usually tell you which category yours falls into once we have the VIN, and we will say so if the dealer is the right answer.
Can you reach me inside a gated or guard-gated community?
Yes, as long as we can get in. In places like Westcliffe or Hillcrest, tell the guard house to expect us and give us your name and address. For a code-gated village, share the code or have someone open the gate. Mention the gate when you call so we plan for it.
My key broke off in the ignition. Is that the same job?
Not exactly. A broken key in the ignition is a different problem, and it can involve the ignition itself. If your ignition is damaged or sticking, see our ignition repair page. If the key is gone completely, that is the lost-key work described here.
What if I only lost the fob and still have the metal key?
That is a smaller problem than losing everything, and it is handled differently. See our key fob replacement page for that, and our transponder key programming page if the chip rather than the remote is the issue.
Can I call at night or on a holiday?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year. Night and holiday calls may affect the cost, and we tell you that on the phone rather than at the car.
