What happens when every car key is lost?
Losing your only key is a bad moment. Losing all of them is a different problem, because there is nothing to copy. A normal duplicate starts with a working key. This job starts with nothing but the car, its VIN and proof that the car is yours. That is why we call it lost car key replacement rather than key cutting: the key gets built from scratch.
In Santa Fe Springs it usually looks like one of a few situations. A key slipped out of a pocket somewhere between work and home and you have already retraced the whole route. The spare was in the house, but the house is locked too. The only key was on a ring that left with a stolen or misplaced bag. Or a used car came with a single key, and now that one has vanished. Every version ends the same way: the car will not start, and the practical next step is someone who can make a key on-site.
We are Wilshire Lock & Key, in business since 1987, and this is routine work for us. Our approach is to be straight about what your particular vehicle needs before anyone starts cutting metal. The phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round.
How do we replace a lost car key, step by step?
Every vehicle is a little different, but the job follows the same order. Here is what you can expect from the first call to the last test.
The van-based part of this is the same setup described on our page about a mobile locksmith in Santa Fe Springs. The point is that the work comes to the car, so you are not arranging a tow just to get a key made.
- You call (213) 577-1366 and give us the make, model, year and where the car is parked, including cross streets or a nearby landmark.
- We tell you in plain terms what type of key your vehicle likely uses and what the work involves. If your car turns out to be a dealer-only case, we say so at this point, not after a van has shown up.
- A technician drives to the car with the equipment for the job.
- At the car, we verify ownership: photo ID plus registration or title that matches the VIN. We do this every time, and it protects you as much as us.
- We read the VIN and work out the key blank and cutting information for that vehicle.
- We cut the new key and, where the vehicle requires it, program it so the car's anti-theft system accepts it.
- You test it: unlock, start the engine, and try every door and the trunk. We do not pack up until it works.
- We talk through a spare key and what to do if the old one turns up.

Call (213) 577-1366Can you really get a replacement car key without the original?
Yes, in most cases. A key does not need an original to exist. The cutting information for a vehicle can be worked out from its VIN, or in some cases read from the car's own locks, and a new key can be cut from that information. If the car's security system requires the key to be recognized electronically, the new key then has to be programmed to the vehicle.
The honest part is that all keys lost is harder than adding a spare when you still have a working key. Some vehicles make the all-keys-lost process straightforward with the right equipment. Others need more steps, and a few makes or security setups can only be handled with dealer access to codes or software. When your car is one of those, we say so up front and point you toward the dealer rather than promise something we cannot do. We confirm this by VIN or in person, not by guessing from a model name.
One more thing worth separating out: sometimes the key was never really the problem. If the ignition is worn, jammed or damaged, a brand-new key will not turn it. That is a different repair, covered on our ignition repair page, and a good technician will tell you if that is what is going on while we are at the car.
What kind of key does your car use?
The type of key is the biggest factor in how the job goes, so it is worth understanding the main categories. We confirm which one applies to your vehicle by VIN or in person. The model name alone is not enough, because the same model can change between years and trim levels.
Broadly, these are the types we run into:
- Plain metal key: cut only, no electronics, usually the simplest job.
- Transponder key: a metal key with a chip inside the head that the car has to recognize before it will start. The key must be cut and programmed. Our transponder key programming page goes into that process.
- Remote-head key: the key blade and the lock and unlock buttons in one piece, usually requiring cutting, programming and remote pairing.
- Smart or proximity key: used with push-button start. These need programming and sometimes more equipment, and they are where dealer-only cases are most likely to come up.
- Emergency blade: the hidden metal key inside many smart fobs, used for the door if the battery dies. If you only lost the fob, see our key fob replacement page.

Call (213) 577-1366What affects the cost of replacing lost car keys?
We do not put dollar figures on a web page, because the honest number depends on your VIN and your situation, and any site quoting one number for every car is guessing. What we can do is tell you exactly what moves the cost, and give you the shape of it on the phone before we dispatch anyone.
In general, a mobile locksmith is usually the more economical route compared with towing a car to a dealer and waiting on their schedule. That is not true for every vehicle, and when the dealer really is the only option, we will tell you.
- The key type: a plain cut key and a smart key are very different jobs.
- The make, model and year, and how that manufacturer's security system works.
- Whether the key needs programming, remote pairing, or both.
- How many keys you want made. Making a spare during the same visit is usually more efficient than coming back later.
- The condition of the ignition and locks, since a damaged ignition adds a separate repair.
- Where and when the work happens, including after-hours calls and hard-to-reach spots.
- Whether the vehicle is a dealer-only case, which changes the whole plan.
Why call Wilshire Lock & Key for a lost car key?
Plenty of companies will answer the phone. What matters is who actually shows up and what they can do when they get there. Here is how we are set up:
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work begins. It is a fair question and a good habit. For the wider picture of what we handle on the road, see our automotive locksmith page.
- In business since 1987, so we have seen a long run of vehicles and key systems come through.
- A real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. You can find us at an address, not just a phone number.
- One company, no dispatch middlemen. The person you call is not a call center reselling your job to whoever is free.
- David, the owner and lead technician, oversees the work.
- The phone is answered 24 hours a day, every day of the year, and we serve 140 cities across Los Angeles and Ventura counties.
What does lost car key replacement look like in Santa Fe Springs?
Santa Fe Springs is mostly an industrial city, with a small residential core of 1950s tract homes around Telegraph Road and the Town Center area. That mix shapes the calls. In the Town Center and Telegraph Road residential core, in the Little Lake Park neighborhood near Lakeland Road and Pioneer Boulevard, and across the Lakeland Road area, a lost car key usually means a car sitting on a driveway or curb outside a single-story home, with someone who needs to get to work. For those calls we come to the street, verify ownership, and do the work at the car. Everything here falls under ZIP code 90670.
The other side of the city is the Santa Fe Springs Road industrial corridor and the logistics yards and truck terminals around it. Fleet vehicle key replacement is a real scenario here: when a key goes missing on a work vehicle, a parked vehicle means lost work, and sitting around is expensive. If the vehicle is a heavy commercial truck, say so on the first call, so we can confirm by VIN what is possible before sending a van. If you manage several vehicles, tell us how many keys you need and we can plan one visit instead of several.
To help us find you quickly, give cross streets plus a nearby landmark, such as Heritage Park, the Santa Fe Springs Swap Meet, Town Center Hall on Telegraph Road, or the Norwalk/Santa Fe Springs Transportation Center. Summer heat on a flat inland plain is no fun to wait in, so a van that comes to you matters. We are based in Westwood, and Santa Fe Springs is one of the 140 cities our vans serve.

Call (213) 577-1366What should you have ready before you call?
A few details speed everything up and keep the quote honest. You do not need all of them to call, but the more you have, the clearer the plan.
- The make, model and year of the vehicle.
- The VIN, which is usually visible at the base of the windshield on the driver's side, on the driver's door jamb, and on your registration or insurance card.
- Photo ID, plus registration or title that matches the vehicle.
- The exact location of the car and whether it is on private property, a street or a lot.
- How many keys you want made.
- Whether you know the car is locked, or whether a key might be inside it.
What should you do after the new key works?
First, get a spare. Having two keys is what turns the next loss from an emergency into an inconvenience. A spare made while we are already at the car is usually more efficient than a second trip, and our key duplication service covers copies of keys you already have working.
Second, ask whether your vehicle allows lost keys to be removed from the car's memory, so a key that turns up in the wrong hands no longer starts it. Whether that is possible depends on the vehicle, and we confirm it by VIN.
Third, think about what else was on the ring. If your house or work keys were with the lost car key, that is a separate conversation, and we are happy to talk through your options. If the key is just sitting under a couch cushion, though, put it somewhere sensible and make that the spare.
Frequently asked questions
Can you make a car key if I have lost all of them?
In most cases, yes. We work from the VIN and proof of ownership, cut a new key, and program it if the car requires it. Some makes and security systems are dealer-only, and we tell you that honestly when we know it.
Do I need to tow my car to get a new key?
Usually not. Our mobile vans come to the car in Santa Fe Springs and do the work there. A tow only enters the picture if your vehicle turns out to need dealer-only equipment.
How much does lost car key replacement cost?
It depends on the key type, the make and year of the vehicle, whether programming is needed, how many keys you want, and when and where the work happens. We explain the shape of the cost on the phone before we send anyone.
What proof of ownership do you need?
Photo ID plus registration or title that matches the VIN on the vehicle. We check this every time, which protects you from someone else getting a key to your car.
Will my car need the dealer?
Most of the time it will not, but some makes and models can only be handled with dealer access to codes or software. We confirm by VIN or in person and tell you up front if yours is one of them.
How long does it take to replace a lost car key?
It depends on the key type and the vehicle. A simple cut key moves quicker than a smart key that needs programming. When you call, we give you a realistic expectation for your car rather than a one-size answer.
Will the lost key still start my car after you make a new one?
It depends on the vehicle. Some systems let lost keys be removed from the car's memory so they stop working, and others do not. Ask us when you call and we will confirm by VIN.
Do you work at night and on weekends in Santa Fe Springs?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round, and our vans serve Santa Fe Springs and 139 other cities across Los Angeles and Ventura counties.
