What does lost car key replacement mean when every key is gone?
Most people call a locksmith for a spare key. This page is about the harder situation: you have no key at all. There is nothing to duplicate, nothing to trace, and nothing to pair a copy against. The industry term is an all keys lost situation, and it is a different job from cutting a duplicate.
With no original, the new key has to be built from information about the car itself. That means working out the correct key cut for your vehicle, producing a blade or key that fits the locks, and then, if your car uses an electronic key, getting the car to accept it. Each of those steps depends on the vehicle, which is why the first thing we ask on the phone is the make, model, and year.
If you are searching for a replacement car key without the original, here is the plain answer. It can usually be done on site, in your driveway or parking lot, without towing the car. It cannot be done instantly or identically for every vehicle, and we will tell you which kind of car you have before we start work.
What actually happens when you lose all your car keys?
Losing the last key is rarely a calm event. The key went into a gym bag, a jacket pocket, or a restaurant table and did not come back out. Sometimes it was a single key that was never copied, and sometimes both keys went missing together because they lived on the same ring.
Before anyone cuts or programs anything, there are a few things worth sorting out. These questions shape the whole job:
- Is the car locked, or is it still open? If it is locked with nothing inside to reach, we may need to get in first. That is a separate step covered under car lockout service in El Monte.
- Does your car use a plain metal key, a key with a chip in the head, a remote key fob, or a push-button start with a smart key? Each one is made differently.
- Are you the registered owner, and can you show it? We ask for proof of ownership and identification on every lost-key job. That protects you as much as it protects us.
- Could the key have simply been left in the car, or is it truly missing? A quick, honest search first can save you a service call.
- Is there any chance it was stolen with a bag or wallet that has your address? If so, you may also want the house locks looked at, which is a different job we can handle.

Call (213) 577-1366How do we make a replacement car key without the original?
Every vehicle is a little different, but the sequence is consistent. Here is how a lost-all-keys job generally goes when you call us.
- You call (213) 577-1366. Someone answers at any hour. We take the make, model, year, and your location, and we tell you honestly whether your vehicle is something we can do on site.
- We confirm the vehicle by VIN or in person. The VIN, found on the dashboard near the windshield and on the door jamb sticker, lets us verify the exact key type and any security details before we cut or program anything.
- We verify ownership. We ask for ID and proof the car is yours, such as registration or title. We do not make keys for a vehicle without that.
- We get a key code or decode the lock. Depending on the vehicle, the key cut comes from a code tied to your VIN, or from reading the lock itself.
- We cut the key. The blade is cut to fit the locks, whether it is a plain key, a chip key, or the emergency blade inside a fob.
- We program the electronic side if your car needs it. Many vehicles will not start unless the car recognizes the key. That step is covered in more detail under transponder key programming and, for remotes, key fob replacement.
- We test everything. The key should turn the door lock, turn the ignition, start the car, and operate any remote buttons before we call it done. We also check that you have what you need to use the key daily.
What affects the cost of lost car key replacement?
We do not publish a flat number for lost-key work, because honest pricing depends on the vehicle. When you call, we will go through the factors below and give you a clear picture before we begin. Here is what moves the cost up or down.
The biggest factor is the type of key. A plain metal key with no chip is a simpler job than a chip key, and a chip key is simpler than a smart key for a push-button car. The more security the car has built in, the more equipment and time the job takes.
The second factor is whether the car can be handled on site or has to go through the dealer. Some makes and models are straightforward for a mobile locksmith. Others require a process that only the dealership can complete. We say so up front rather than starting a job we cannot finish.
Other things that affect cost include:
- How many keys you want made. Having us make two at once is usually more economical than making one now and another later, since the setup work is shared.
- Whether the car needs to be unlocked first, or the ignition or door lock is worn or damaged and also needs attention.
- Whether the car is somewhere simple to reach or somewhere we have to work around, such as a tight garage or a busy lot.
- The time of day. Night, weekend, and holiday calls take staff and vans out of normal hours.
- Distance. El Monte is about 25 miles from our Westwood base, and travel is part of the picture on any mobile job.
- Whether there is existing damage, like a broken key stuck in the ignition, which is handled separately through broken key extraction if it applies.

Call (213) 577-1366When is the dealer the only option?
We would rather tell you this plainly than let you find out after an hour of waiting. For certain vehicles, an all-keys-lost situation can only be completed at the dealership, because the key information or the programming access is restricted to them. That is more likely with some newer or higher-security models.
What we do not do is guess. Key and chip details vary by make, model, year, and sometimes by trim level, and published information about specific vehicles is not always consistent. So we confirm by VIN or in person before we promise anything. If the car turns out to be dealer-only, we will say so, and you will not be charged for a job we could not do on site.
If your car has to go to a dealer, we can still help with the parts around it, like getting the car unlocked so it can be moved, or looking at the ignition and lock hardware if there is wear. Our automotive locksmith service covers the rest of the vehicle-side work.
There is also a middle case worth knowing about. Some vehicles can be done by a locksmith, but the dealer route may suit your situation better, for example if the car is still under a warranty or service plan that covers keys. If that is true for you, ask your paperwork before you call anyone.
Lost car key replacement in El Monte: where the calls come from
El Monte sits in the flat San Gabriel Valley basin, in ZIP codes 91731 and 91732, and the summers are hot and dry with little coastal relief. That matters for car keys more than people expect. Heat and a sun-baked dashboard are hard on key fobs and on plastic key heads, and a key that has been worn for years can finally fail in August.
Think about where an El Monte driver actually loses a key. Someone who commutes through the El Monte Station transit center may park near it, take the bus or train, and realize at the end of the day that the keys are gone. A shopper walking the Valley Mall pedestrian district in Downtown El Monte can set a key down at a counter and leave without it. The car stays parked, and the owner is stuck on foot.
Neighborhood patterns matter too. In Five Points, Mountain View, and Norwood Village, many cars sit on the street or in driveways in front of postwar bungalows, and a lot of the housing here is renter-occupied with small apartment complexes and backyard units. That means one household may have several vehicles and very few spare keys. A single lost key often turns into an all-keys-lost job because nobody ever made a copy.
We come to you rather than the other way around. If the car is at home in Arden Village, at work in the Flair Park business district, or parked near the Northwest Industrial District, our van can meet you there. A lost-key job fits well with mobile service because the car often cannot be driven to a shop in the first place. You can see our wider local coverage on our El Monte locksmith page.
One more local note: if your lost car key was on the same ring as your house or apartment key, you may be locked out of both. We handle those as separate jobs, but we can plan them together so you only need one visit.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
There are plenty of places to find a locksmith. Here is what we can honestly say about ours.
We have been in business since 1987, and David, the owner and lead technician, oversees the work. Wilshire Lock & Key is one company with a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. When you call (213) 577-1366, you reach us, not a call center that sells your job to the nearest stranger. There are no dispatch middlemen between you and the person doing the work.
Our phones are answered 24 hours a day, 7 days a week, year-round, because keys do not get lost on a schedule. We cover 140 cities across Los Angeles and Ventura counties, which means we are used to working in many different kinds of neighborhoods and parking situations, and we know what a vehicle call involves from the first conversation.
One more thing worth saying. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you are considering for that number before they start. It is a fair question and a good habit for any trade you hire.
If you want a broader look at our vehicle-side work, see our car key replacement page, which also covers situations where you still have a working key.
What should you do before we arrive?
A little preparation shortens the job. None of this is required, but it helps us arrive with the right equipment, and it means less standing around in the heat.
Gather what you can while you wait. Then, if your key situation involves something else we can help with, mention it on the phone so we can plan for it.
- Know the make, model, and year of the car, and where the VIN is. A photo of the VIN plate through the windshield is enough.
- Have your ID and proof of ownership ready, such as registration or title.
- Check the obvious places once more: pockets, bags, the car seat, a coat at work, and the last place you stopped.
- Tell us if you have a worn key, a stuck ignition, or a steering wheel that will not turn. Those hint at hardware trouble, and ignition repair may be part of the fix.
- Park somewhere safe and reachable if you can, ideally with enough room to open the doors and work beside the car.
- Do not try to force the door or the ignition. It can turn a simple key job into a lock or window repair.
Frequently asked questions
Can you make a car key if I have lost all my keys?
Often yes, and usually on site. For many vehicles we can make a new key from scratch without an original. The details depend on the make, model, and year. Some vehicles can only be completed at a dealership, and we tell you that honestly before we start. We confirm by VIN or in person first.
Do I need the original key to get a replacement car key?
No. A replacement car key without the original is exactly what an all-keys-lost job covers. We work from your VIN, the vehicle details, and the car's own locks to build a new key. What we do need is proof that the car belongs to you.
What do I need to show you before you make a new key?
We ask for a government ID and proof of ownership, like a registration or title, and we match them to the vehicle. It can feel like extra effort when you are stranded, but it is the same step that keeps someone else from making a key to your car.
Will you come to me in El Monte, or do I have to tow the car?
In most cases we come to you. Our mobile vans serve El Monte, including both the 91731 and 91732 ZIP codes, and the work is usually done where the car is parked. Towing is only worth considering if the car turns out to need dealer-only programming. If you are curious about the van side, see our mobile locksmith service.
Is it cheaper to use a locksmith or the dealer for a lost car key?
It depends on the vehicle, so we do not claim one is always the lighter-cost option. A mobile locksmith often saves the cost and trouble of towing, and can usually come to you. For some vehicles only the dealer can do the job. We will tell you which applies to your car on the first call.
How long does it take to replace a lost car key?
It varies by vehicle. A simpler key takes less time than a smart key that needs programming. We do not quote a fixed time over the phone because it would not be honest. We can tell you what steps your car needs, and you will see the work done in front of you.
My car is locked and the keys are gone. Can you handle both?
Yes. We get into the car first if needed, then move on to making the key. Unlocking the car is its own step, and you can read about it under car lockout. We plan both parts into one visit so you do not have to call twice.
Will my old lost key still start the car after you make a new one?
For many vehicles with electronic keys, the old key can be removed from the car's memory when the new one is programmed, so a lost key can no longer start it. Whether that is possible depends on the vehicle, and we confirm by VIN or in person. Ask us about it when you call.
Can I get a spare made at the same time?
Yes, and it is worth doing. Making a second key while we are already set up is usually the more economical route than calling us again later. Then you are not one lost key away from the same problem. Call (213) 577-1366, or use our contact page to reach us.
