What happens when you lose all your car keys in Signal Hill?
Losing your only key is annoying. Losing every key is a different problem, and it helps to understand it before you start making calls. When there is no working key and no spare, there is nothing to copy. A quick duplicate or a clone is off the table. The key has to be created from scratch, and for most modern cars that means two separate jobs: cutting a physical blade that fits your locks and ignition, and getting the car's computer to accept a new electronic key.
That is what lost car key replacement means at Wilshire Lock & Key. We build a new key from your vehicle's identifying information instead of from an original. Your car stays where it is, and our mobile van comes to you in Signal Hill, so you are not arranging a tow just to start the process. Whether a particular car can be finished on the spot depends on its make, model and year, and we will say so plainly when you call instead of promising something the car will not allow.
If you still have one working key and only want a spare, that is a different and usually simpler job. See our page on key duplication for that. This page is for the situation where every key is gone and you need a replacement car key without the original.
How does a replacement car key get made without the original?
The details change from car to car, but the path is consistent. Here is what a typical all-keys-lost job looks like from the first phone call to the moment the engine starts.
- You call (213) 577-1366, which is answered 24 hours a day. We ask for the year, make and model, where the car is parked, and whether it uses a metal blade key, a key with a plastic head, or a push-button start with a smart key.
- We confirm the vehicle is yours. That means the VIN, a registration or title, and photo ID that matches. The VIN is usually visible at the base of the windshield on the driver's side and on the door jamb sticker.
- We work out exactly which key and which system your car uses. Many models were built with more than one key or immobilizer setup in the same year, so we confirm by VIN and in person instead of guessing from the model name.
- We get the cutting information. Depending on the car, the blade is cut from a code tied to your VIN, or the lock itself is read and decoded so the new key matches it.
- We cut the new blade, or prepare the new smart key, using equipment carried in the van.
- We connect to the car's diagnostic port and program the new key so the immobilizer accepts it. On many cars an all-keys-lost situation requires a different procedure than simply adding a spare.
- We test everything before we leave: the door locks, the ignition or start button, and any remote lock and unlock functions. You watch it work before the job is finished.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366What should I have ready when I call?
A few details speed things up and keep us from sending the wrong equipment. None of this is complicated, and you can usually find most of it from your phone or your glove box, assuming you can get into the car.
- The year, make and model of the vehicle, and the trim if you know it
- The VIN, from your registration, your insurance card, or a photo of the dash plate
- Your registration or title, plus photo ID with the same name
- Where the car is parked and whether it is currently locked
- What your lost key looked like: a plain metal key, a key with a thick plastic head, a flip key, or a push-button fob
- Whether any spare could exist somewhere, such as with a family member, a previous owner, or in a drawer at home
Which cars are straightforward, and which are not?
Not every car is equally easy to rekey electronically, and we would rather tell you that now than after we arrive. Older vehicles with a simple metal key and no chip are the most direct: cut a blade and you are done. Most cars from the last couple of decades carry a chip in the key, called a transponder, and the car will not start until it recognizes that chip. Our page on transponder key programming explains how that part works.
Push-button cars with smart keys add another layer. Those keys talk to the car wirelessly, and getting a brand-new one accepted when all keys are lost can be more involved. If your lost item was a remote or smart fob, you can also read about key fob replacement, which covers the electronic side in more detail.
Some vehicles are dealer-only for an all-keys-lost situation. On certain makes, the manufacturer holds the key data or the security access in a way an independent locksmith cannot reach, or the process requires a dealer-issued code or part. When that applies to your car, we will say so honestly, and you will not pay for work that cannot be completed. We do not rely on a general chart for this. We check your actual VIN, because information about specific models is sometimes incomplete or conflicting, and we would rather confirm than assume.
Two related situations are worth separating from this page. If the car is locked and the keys are inside, that is a car lockout, which is a different and simpler job. If the key snapped or the ignition itself is damaged, you may need ignition repair before or alongside a new key, and we will look at the ignition when we are there.

Call (213) 577-1366How much does lost car key replacement cost in Signal Hill?
We do not quote a flat number without knowing your car, because the same service can mean very different amounts of work. What we can do is explain what moves the cost, so a quote makes sense when you hear it.
- The type of key. A plain metal key, a chipped key, a flip key and a push-button smart key each involve different parts and different programming effort.
- The make, model and year. Some vehicles need extra security steps for an all-keys-lost job, and some parts cost more than others.
- How the blade is cut. A key that can be cut from a VIN-based code is a different job than one where the lock has to be read and decoded first.
- The condition of the ignition and locks. If something is worn or damaged, it can affect how the new key works.
- The time of day. Late-night and holiday calls take us out of a normal schedule, and that is reflected in the quote.
- Whether you need more than one key. Making two keys in one visit is usually the more economical route than coming back later for a spare.
Should I call a locksmith or the dealer for a lost car key?
Both are legitimate routes, and the right one depends on your car. A dealer can handle any key for the brands it sells, but you generally need to get the car there, which can mean a tow when no key works, and you work around the service department's schedule. A mobile locksmith comes to the vehicle, cuts and programs the key on site, and can do it outside normal business hours. For many cars, that makes the locksmith route the more economical and more convenient one, though not for every vehicle.
There are also cars where the dealer is the only option, and we will tell you if yours is one of them. Ask for a clear answer on both routes before deciding. If we cannot do your car, we would rather say so on the first call than waste your evening.
Whichever way you go, ask the person for their California locksmith license. California requires locksmith companies to hold a BSIS LCO license, and any locksmith you call should be willing to show it to you.
Lost all car keys in Signal Hill: what it looks like on the ground
Signal Hill is a small city with a mix of settings, and lost keys show up differently in each. The 90755 ZIP code covers everything from hilltop view homes to apartment blocks to commercial strips, and our approach adapts to where your car actually is.
On the hilltop, in the view-home district around Panorama and Skyline drives, the typical case is a car parked in a driveway or garage with no working key anywhere in the house. In those cases we come to the driveway, do the work there, and avoid any towing. The same goes for the gated Promontory at Signal Hill communities, where it helps to give the gate code or arrange entry with a resident before we arrive so we can reach your vehicle without delay.
Down on the lower slopes and along Willow Street, many people park on the street or in apartment lots. A lost key there often goes hand in hand with a locked car or a missed move-out. If the building lock is also in question, our page on apartment lockouts is not on this list, but the same phone line covers it. The Eastbluff Estates area and the neighborhoods near California Heights across the Long Beach line are similar: tell us the cross street and where the car is, and we will find you.
The Signal Hill Auto Center on Cherry Avenue is worth a specific mention. If you bought a car there and lost the only key, the dealership may have its own process, and we are not in a position to speak for how any dealer handles it. For many cars, though, a mobile locksmith can reach the same result at your location. Our storefront is in Westwood at 10740 Wilshire Blvd, roughly 29 miles from Signal Hill, and the mobile service vans do the actual work at your car, so you are not driving anywhere.
Keys also go missing at parks and shopping stops. Whether you last had them at Hilltop Park, Signal Hill Park, Discovery Well Park or on a run to Costco Signal Hill, the first step is the same: check the obvious spots once, then call us with your VIN and location. The marine layer and onshore breeze up here are a reminder that outdoor keys can end up wet or lost in landscaping, so if you were outside before you noticed, a quick look around is reasonable before assuming everything is gone.

If your car is stuck in a lot at midnight, you do not wait for business hours. Our mobile locksmith service is built for exactly that kind of call.
We also try to be plain about it when a job is not what you expected. If your car needs the dealer, we say so. If you only need a spare and not a full replacement, we say that too.
What should I do right after I realize every key is gone?
Stay calm and take a few simple steps in order. They save time and prevent small problems from becoming bigger ones.
- Retrace your steps once. Check the last place you parked, your pockets and bags, and any place the key could have fallen out.
- Look for a spare. Ask family members, roommates or a previous owner, and check any drawer where spare keys tend to end up.
- Do not force the ignition or the door. Trying a wrong key or prying at the lock can damage parts and raise the cost of the job.
- Pull up your VIN and registration. A photo of both on your phone makes the call much faster.
- Think about what else was on the key ring. If house or work keys went with it, mention that when you call, because you may want to change those locks as well.
- Call (213) 577-1366 with your location, your vehicle details, and anything you know about the key you lost.
Frequently asked questions
Can you make a new car key if I have lost all of my keys?
In most cases, yes. We create the key from your VIN and the information in your vehicle, with no original needed. Some cars are dealer-only for an all-keys-lost situation, and we confirm that by VIN before starting so you know where you stand.
Do you need my original key to make a replacement?
No. This service exists specifically for when no original and no spare are available. We cut a new blade from a code or by reading the lock, then program the electronic part so the car accepts it.
Will I have to tow my car to a shop?
Usually not. Our mobile vans do the work where the car is parked in Signal Hill, whether that is a driveway, an apartment lot or a street. The exception is a vehicle that needs dealer-only equipment, and we tell you that up front.
What proof do I need to show that the car is mine?
We ask for the VIN, a registration or title, and photo ID that matches. We do this to protect you. A locksmith who makes a key without checking is a risk to every car owner, including you.
How much will a lost car key replacement cost?
It depends on the type of key, the make, model and year, how the blade has to be cut, the condition of the ignition, and the time of day. We explain these factors and give you a quote based on your specific vehicle once we have the details.
Will my old lost key still start the car after you program a new one?
On many vehicles, the programming process lets us remove lost keys from the car's memory so they no longer start it. This depends on the vehicle's system, and we confirm what is possible on your car when we check the VIN.
Can you help if the car is also locked?
Yes. If you are locked out with no key anywhere, we get you into the car first and then handle the new key. The lockout is a separate step, but we can do both in the same visit.
I lost my keys along with other keys on the same ring. What should I do?
Tell us when you call. If house or work keys were on the ring, you may want to change those locks in addition to replacing the car key, since whoever finds the ring may know where it belongs.
Do you work at night and on weekends in Signal Hill 90755?
Yes. Our phone line is answered 24 hours a day, seven days a week, all year, and we serve all of Signal Hill. Call (213) 577-1366 with your location and your vehicle details.
