Lost Car Key Replacement When Every Key Is Gone

When it's truly all keys lost, and when it isn't

Locksmiths use the phrase all keys lost, often shortened to AKL, for one specific situation: no key exists anywhere that the vehicle will accept. That distinction matters because it decides how much work the job involves.

It isn't all keys lost if any of these are true: - Someone in the household still has a working key, even one with a scratched blade or a dead remote - A valet key exists, since it carries a programmed chip even though on some models it can't open the trunk or glovebox - The key is locked inside the car rather than missing, which makes it a lockout instead of an origination

It also isn't quite AKL if you have a key that turns the door lock but was never programmed, such as a hardware-store copy made years ago. That key won't start the engine, but its blade spares us the decoding step, so dig it out.

True all-keys-lost means the vehicle has nothing to compare against. There's no blade to trace, and on immobilizer-equipped vehicles there's no authorized transponder to put the system into an easy add-key mode. Everything gets rebuilt from information stored in the car, in its lock cylinders or in the manufacturer's records.

Spend a little time confirming before you call. Ask everyone who has driven the car recently, check coat pockets and the bowl by the front door, and look into the cabin through the windows. A key spotted on the passenger floor mat turns a bigger job into a simple entry.

What to do in the first hour

The steps you take right after discovering the loss affect both the cost and the security of the outcome.

• Secure the car's location. If it's in a store lot, hospital structure or apartment garage with towing rules, tell the property manager or security desk and ask how long the car can stay.
• Collect your paperwork. You need a government photo ID, then the registration, title, lease or loan agreement. Photos on your phone are a good start, and the original can be checked once the car is open.
• Find the VIN. The 17-character number appears on the plate at the base of the windshield, on the driver's door-jamb sticker, on your insurance card and in most automakers' phone apps.
• Note the key type. Was it a plain blade with a plastic head, a flip key, a key with lock and unlock buttons, or a push-button fob that stayed in your pocket?
• Decide whether the loss is innocent or a theft. A key dropped on a trail and a purse snatched from a shopping cart call for different follow-ups.

Then call. Give the year, make, model, VIN, key type, the car's exact location and whether it's accessible. That conversation tells us whether your vehicle is an on-site job, needs a PIN or code request ahead of time, or belongs to the small group of vehicles whose keys come only from the dealer.

Hold off on buying a key online while you wait. A blank that looks right in a listing photo can be the wrong frequency, the wrong chip, or already locked to another car.

Proving ownership: what we ask for and why

California regulates locksmiths through the Locksmith Act, found at Business and Professions Code section 6980 and following, and the Bureau of Security and Investigative Services issues and oversees locksmith licenses. Julian's Locksmith operates under license LCO7891, which you can look up at search.dca.ca.gov. Making a key for a car nobody can currently drive is the most sensitive work a locksmith does, so verification comes before tools on every job.

What we ask to see: - A valid government photo ID, such as a California driver's license or ID card, a passport, a military ID or an out-of-state license - A document tying that person to the vehicle: the current registration card, the certificate of title, or a lease, loan or purchase agreement

A California registration card lists the registered owner and, on a financed vehicle, the legal owner, which is usually the lender. The registered owner, or someone with that owner's permission, can request a key.

Situations that need one more step: - Family cars registered to a parent or spouse: we confirm permission with the owner by phone. - Private-party purchases not yet transferred at the DMV: the signed title and a bill of sale. - Company vehicles: written authorization from the business owner or fleet manager. - Rental and car-share vehicles: these belong to the rental company, so the renter needs to go through the company's roadside line. - Impounded or stored vehicles: the tow yard or storage facility controls access and has to agree first.

If any of this seems strict, consider the alternative. A locksmith who skips verification for you will skip it for a thief standing next to your car.

Getting the cuts from a factory key code

Every vehicle key starts as a set of cut depths called the bitting. Automakers assign that bitting at the factory and record it as a key code connected to the VIN. When the code is available, it's the cleanest way to make a key from nothing.

Where key codes come from: - The automaker's records, released through the dealer or through secure systems that let registered locksmiths request codes after verifying ownership - A small tag stamped with the code, which some vehicles shipped with in the owner's manual pouch - Occasionally a number stamped on a lock cylinder itself, more common on older vehicles

A code-cut key has two advantages over a copy. It's made to factory specification rather than reproducing years of wear, and it doesn't depend on decoding a lock that might be worn, sticky or damaged.

Codes have limits, and we'd rather explain them than pretend otherwise. Not every manufacturer releases codes outside its dealer network. Some keep records only for a certain number of model years. And a code reflects how the car left the factory: if a previous owner replaced the ignition or a door lock after a break-in, the code may no longer match the hardware. That's why we test a code-cut key in the driver's door before programming anything. If it doesn't turn smoothly, we decode the actual lock rather than trusting paperwork.

The key is cut on a computerized machine in our van, which follows the code's exact depths and spacing. Laser-cut or sidewinder blades, standard on many vehicles since the 2000s, are cut on the same machine with the appropriate clamp.

Decoding the locks when there's no code

When a code isn't obtainable or doesn't match, the car's own lock cylinders hold the answer. Decoding reads them directly, and done properly it leaves no marks.

The main tool is a 2-in-1 pick and decoder, often called a Lishi after its best-known maker. Each one is built for a specific keyway, such as HU66 for many Volkswagen and Audi models, HU100 for many GM vehicles, HON66 for Honda and Acura, or HY22 for many Hyundai and Kia models. The locksmith picks the cylinder by feel, holds it at the turning point, and reads where each wafer sits. Those readings convert into cut depths.

Real vehicles complicate the picture: - Door locks often contain only some of the wafers the full key uses. The missing positions get worked out by progression: cutting a test key with the known depths, trying candidate depths for the unknown positions, and narrowing down until the key turns. - On push-button cars, the driver's door may be the only cylinder on the vehicle, hidden under a cap on the handle. If it's seized from years of disuse, we lubricate and free it before decoding. - Some cylinders are designed to free-spin when forced, a theft deterrent that also makes picking slower. Patience and the right tension tool matter here. - Occasionally we remove a cylinder from the door or trunk, read the wafers by sight on the bench, then reinstall it.

Drilling is not part of a normal decode. If a lock is damaged beyond reading, we'll discuss repairing or replacing that cylinder as a separate item and quote it before starting.

Programming a key when the car recognizes nothing

Cutting the blade only gets you into the car. Starting it requires the immobilizer, a security function in the engine computer or a related module, to recognize a coded chip in the key. With a working key present, adding another is usually a short routine. With no working key, the system has to be opened another way.

The common all-keys-lost programming routes: - OBD-II programming with professional equipment. Many vehicles let a locksmith reset the key list through the diagnostic port, sometimes after a built-in waiting period meant to slow thieves down. Some GM vehicles, for example, run a relearn in three timed cycles that adds up to roughly half an hour. - Security PIN access. Many Nissan, Infiniti, Hyundai, Kia, Chrysler, Dodge, Jeep and Ram vehicles want a PIN before they'll accept new keys. Depending on the model, the programmer can calculate it from data in the car, or the PIN has to be requested from the automaker with proof of ownership. - Secure gateway access. Many Stellantis vehicles from 2018 on place a security gateway in front of the diagnostic network, requiring either an authorized online connection or a bypass at the module. - Module work. Certain BMW, Volkswagen, Audi and Toyota systems call for reading or connecting directly to a module, such as the instrument cluster, body module or smart key computer, which can mean removing trim or a kick panel.

Battery voltage is a hidden risk throughout. A weak 12-volt battery dropping during a write can corrupt a module, so we test it first and support it with a power supply while programming.

Honest limits: dealer-only keys and special cases

No mobile locksmith can make every key for every vehicle, and you deserve to hear that before anyone drives to your car.

Vehicles that typically go through the dealer when all keys are lost: - Most Mercedes-Benz models from roughly the mid-2010s onward, whose keys are produced by the manufacturer against the VIN and shipped to the dealer - Some recent GM and European models on the newest electrical platforms, where the automaker limits key programming to its own online systems - Teslas and certain other electric vehicles, which manage keys through the manufacturer's app and service network

Even on those vehicles, a locksmith may still be useful. We can open the car so you can retrieve belongings and paperwork, explain what documents the dealer will expect, and show you the shift-lock release so the car can roll onto a flatbed in neutral without harming the transmission. Once a dealer key exists, follow-up work such as adding a remote or cutting a key for a separate toolbox or tonneau lock may come back to us.

Other special cases we'll flag in advance: - Vehicles with a damaged or replaced ignition that no longer matches the door locks - Cars with aftermarket immobilizers or remote-start systems layered on top of the factory system - Imported or gray-market vehicles never originally sold in the US - Vehicles with earlier theft damage to the steering column or wiring

None of these automatically means no. They mean we ask more questions on the phone so the quote reflects the real job, and so you never pay a service call to learn something we could have told you from the VIN.

Erasing the lost keys, and what erasing can't do

A replacement key restores your access. Erasing the lost keys removes everyone else's. On an all-keys-lost job, the programming procedure usually clears the old key list as part of resetting the system. When a customer still has one key but lost another, we clear the list deliberately and re-add only the keys present.

Three separate memories may need attention: - The immobilizer's transponder list, which decides whether the engine runs - The remote or keyless-entry list, which decides which fobs lock, unlock, open the trunk or sound the panic alarm, and which on many cars is reprogrammed as a complete set - Any aftermarket alarm or remote-start module, which keeps its own transmitter memory unrelated to the factory system

After programming, our equipment can usually display how many keys the car recognizes. That number should match the keys in your hand. If it doesn't, something is still registered and needs clearing.

Here's the limit worth understanding. Erasing works on electronics, not metal. The lost key's blade still matches your door locks and, on turn-key vehicles, the ignition cylinder. It can open a door, and on a turn-key car it can turn the ignition, but the immobilizer won't let the engine run. For a key dropped somewhere random, that's usually acceptable. For keys stolen alongside your registration or address, rekeying the door, trunk and ignition cylinders to new cuts closes the remaining gap. On older vehicles with no immobilizer at all, rekeying is the only real protection.

Stolen keys: securing the car and the rest of the ring

Keys that are simply misplaced and keys that were taken deserve different responses. A stolen ring usually comes with context: a purse, gym bag or backpack that also held a license, a mailbox key, an office key or a garage remote.

If your keys were stolen: - Report it to the police and keep the report number for insurance. - Don't leave the car unwatched longer than necessary. A thief holding a key may come back for the vehicle once the owner has gone, so arrange to meet a locksmith at the car promptly or have someone you trust keep an eye on it. - Have the stolen car keys erased as part of the replacement, and consider rekeying the vehicle's locks. - Treat house keys as compromised if anything in the bag connects them to an address. Rekeying the home's locks changes the pins so the old keys stop working, without replacing the hardware. - Change the code on any garage door opener that was on the ring or clipped to the visor, and update keypad and smart lock codes if they were written down anywhere in the bag. - If a mailbox key was included, contact the post office or property manager responsible for your box about a lock change.

We can handle the car and the home on the same visit when both are within our service area, which keeps the window between the theft and fully secured locks as short as possible. That matters most in the first day or two, when whoever took the bag is most likely to try the keys they're holding.

What shapes the price of an all-keys-lost job

We don't publish flat prices for lost car key replacement because the same request can mean very different work. We quote on the phone from your VIN and description, then confirm at the car before starting. These are the factors that move the number:

• Key type. A mechanical key for an older truck, a transponder key, a remote-head key and a proximity smart fob each involve very different blanks and programming effort.
• How the cuts are obtained. A released key code is quicker than decoding, and a decode with lots of progression or cylinder removal takes longer still.
• Programming route. OBD-only vehicles are quickest. PIN requests, security gateway access, timed relearns and module bench work add equipment and labor.
• Manufacturer fees. Some automakers charge for code or PIN retrieval, and that charge becomes part of the quote.
• Number of keys. The first key carries most of the setup cost. Additional keys made in the same visit cost much less than another origination later.
• Additional security work. Rekeying door and ignition cylinders, resetting an aftermarket remote-start system or repairing a damaged lock adds to the job.
• Location and timing. Distance from our San Bernardino base and late-evening calls affect the service portion.

Compared with the dealership, the honest comparison includes the tow, the days without the car, and the dealer's own key and programming charges. For many vehicles the mobile route comes out ahead on total cost and time. For dealer-only vehicles it isn't an option, and we'll say so before you spend anything.

Hours, service area and what to do when we're closed

Julian's Locksmith is a mobile service based in San Bernardino. We drive to the vehicle across the Inland Empire, the San Gabriel Valley, the Pomona Valley, north Orange County and southeast Los Angeles County, carrying the key machine, blank inventory, decoders and programming equipment so the car never has to move.

Our hours, Pacific time: - Monday through Friday, 6:30 a.m. to 11:30 p.m. - Saturday and Sunday, 6:30 a.m. to 11:30 p.m. - Closed overnight, 11:30 p.m. to 6:30 a.m.

We're not a 24/7 service, and we'd rather tell you that than make a promise we can't keep. All-keys-lost work also tends to take longer than a lockout, so calling earlier in our day leaves room for a code request or a decode without running into closing.

If your keys go missing while we're closed, the car can usually wait safely. Leave it locked where it is if the location allows, let any property manager know, gather your ID and paperwork, photograph the VIN plate, and call when we open. If the car is somewhere unsafe or about to be towed, a short tow to your home is often cheaper than a long tow to a dealer followed by days in a service lane, and we can make the key in your driveway the next day we're open.

When you call (951) 903-3193, have the year, make, model, VIN, key type and location ready. We'll tell you whether your car is an on-site job, what we need to verify ownership, and give you an honest ETA before we head your way.
