Lost your car key, cracked a fob, or down to one key?
Most people call about a car key at a bad moment. The key fell out of a pocket somewhere between a parking space and the front door. The plastic case on a fob split and the buttons stopped answering. Or the key still works, but it is the only one, and you have started to worry about what happens the day it doesn't. Each of those is a different job, and the first thing we do is work out which one you actually have.
Car key replacement is the work of making a new, working key for a vehicle: cutting the metal blade when there is one, and programming the electronics so the car accepts it. We do both at your vehicle, from a mobile van, so you do not have to tow a car to a shop or arrange a ride to a dealership across the valley. Our storefront is at 10740 Wilshire Blvd in Westwood, and the vans that serve Valencia work from the same company, not a call center that passes your request along to someone else.
This page covers replacements, duplicates, and spares. If you are locked out with the key inside, that is a different job, covered on our car lockout page. If a key has snapped in a lock or ignition, that is broken key extraction. Here we stay on getting you a new key that starts the car.
What kinds of car keys can we replace, cut, and duplicate?
Car keys have changed a lot over the decades, and the type of key in your hand decides how the job goes. We will not guess at what your car uses from a general description. We confirm it by VIN and by looking at the vehicle and any key you still have, because what a given year, make, and trim uses is not always consistent, and sources sometimes conflict. If a particular vehicle can only be done through the dealer, we tell you that plainly instead of pretending otherwise.
- Basic cut keys: a metal key with no electronics. These are the simplest to duplicate, and car key cutting is most of the work.
- Transponder keys: a key with a chip in the head that the car must recognize before it will start. The blade gets cut and the chip gets programmed. More on that at our transponder key programming page.
- Remote head keys and key fobs: the key and lock/unlock buttons in one unit, or a separate remote. See key fob replacement for the details of those.
- Smart or proximity keys: the push-button-start style where the key stays in a pocket. Replacement depends heavily on the vehicle, and this is where we are most careful to confirm before promising anything.
- Ignition and door keys that have worn down: sometimes a copy of a worn key carries the wear along with it, so we may cut a fresh key by code or by the lock instead of tracing the old one.

Call (213) 577-1366How does mobile car key replacement work, step by step?
The process is the same whether it is a duplicate car key you planned for or an emergency at night. Here is how it goes from the first call.
- You call (213) 577-1366. Someone answers, day or night. Tell us the year, make, and model, where the car is, and what you have: no keys, one key, or a broken one.
- We ask a few questions about the vehicle. Push-button start or a key slot? Does a spare exist anywhere, even at a relative's house? Is the car locked, and are the keys visible inside? These answers shape what we bring.
- We tell you what we can do and what we cannot do from the van. If your car is one that has dealer-only steps, we say so before anyone drives out.
- A technician arrives at your vehicle with key blanks, cutting equipment, and programming tools.
- We verify you are entitled to the vehicle. Expect to show ID and proof of ownership, such as registration or title, that matches the car. We ask for this on every job, because a locksmith who makes a car key for anyone who asks is a risk to every car owner.
- We cut the key, program it to the vehicle, and, where it applies, program the remote functions.
- You test everything before we finish: start the car, turn it off, lock and unlock the doors, try the buttons, and try the key in the door and the ignition. We want the problem found while we are standing there.
What affects the cost of car key replacement in Valencia?
We do not quote a number on a web page because the same phrase, car key replacement, can describe jobs that are quite far apart. What we can do is tell you exactly what moves the cost, so a quote over the phone makes sense when you hear it.
If a locksmith gives you a number without asking about the vehicle, treat it as a guess. A real quote starts with the car.
- The type of key: a plain cut key is a smaller job than a transponder key, and a smart key is usually a larger one than either.
- Whether you have a working key: a spare car key made from an existing key is generally the lighter-cost route compared with an all-keys-lost situation, where the car has to be set up to accept a new key from scratch.
- The vehicle itself: some makes and model years are straightforward for a mobile locksmith, and others need more equipment, more steps, or access that only a dealer has.
- The parts: the blank, the remote, and the case are real components, and quality ranges. We tell you what we are using.
- Remote functions: a key that starts the car is one job; a key that also locks, unlocks, and opens the trunk with buttons is another.
- Time of day and distance: night, weekend, or holiday calls take people away from their families, and Valencia is about 34 miles from our Westwood storefront. We include those in the quote up front instead of surprising you afterward.
- How many keys: making two at once is often more economical than making them on separate visits.

Call (213) 577-1366Why a spare car key is easier than waiting until all keys are lost
If you are reading this with one key in your pocket and the car running fine, you are in the best position to save yourself trouble. Making a spare car key while a working key exists is the usually more economical route. We can often work from the key you have, and the car does not have to be reset around a total loss.
If you have lost every key, the job is still doable in many cases, and it is something we do from the van. It just involves more steps, and it is the reason a duplicate costs less than a replacement after everything is gone. Our lost car key replacement page goes through what that process looks like.
A practical suggestion: when we make a new key for you, ask for a second one in the same visit. Keep one at home in a place you will remember, and not in the car. A spare that lives in the glove box is not a spare when the car is locked or stolen.
When the key is fine and the ignition is the problem
Sometimes people call for a new key when the key was never the issue. If a key goes in but will not turn, turns only with effort, or sticks and wiggles, the ignition cylinder may be worn or jammed, and a new key copied from the same worn key will not fix it. The reverse also happens: the cylinder is fine, but the old key is so worn it no longer lifts the pins properly.
We check this before cutting anything, because there is no point in selling you a key that will not solve the issue. If the ignition turns out to be the failing part, that is a separate repair, described on our ignition repair page. Dust is worth mentioning too: Valencia gets wind-blown dust during Santa Ana events, and grit can find its way into door locks and ignition cylinders over time. If a key has started to feel gritty, say so on the phone. It may be a clean-and-service job, not a new key.
Car key replacement across Valencia's villages
Valencia is a master-planned community of named villages connected by paseos, and cars here are usually parked in places with a lot of structure around them: HOA streets, driveways, and garages. That affects how we find you. Give us the village or cross streets, the ZIP (91354 or 91355), and any gate details, and we can plan the visit. In gated enclaves such as Westridge, we need your gate code or a resident to let the van in, so mention it when you call.
Here are a few situations that fit this area. Someone in Bridgeport or Northpark has a transponder key that went through the wash, and the car now starts only on the first try. Someone in Valencia Summit has a teenage driver heading off to college and wants a duplicate car key made before the household has no spare. Someone near Town Center along the McBean Parkway corridor has a car parked at a condo while the only key is inside the unit, and needs help with both the door and the key. For that last case our apartment lockout page covers the unit side, while this page covers the car.
Student housing near CalArts brings its own version of this: a student with one key, a shared apartment, and a car that cannot be left stuck for long. If that is you, tell us whether the car is registered in your name, because we need proof of ownership that matches the vehicle. If a parent holds the title, plan on that conversation before we arrive.
Valencia's summers are hot and dry with big swings between day and night. Heat is hard on the plastic cases and battery contacts in fobs, and a fob that has been cooking on a dashboard may need a new case or battery before it needs a new key. We check that first. FivePoint Valencia on the west side has newer homes and newer vehicles, and the newer the car, the more likely we are to confirm details by VIN before saying what is possible.
Our mobile locksmith service is built around this. The work happens where your car is parked, whether that is a driveway, a parking structure, or the side of a road.

Call (213) 577-1366Why call Wilshire Lock & Key for your car key?
We have been in business since 1987, and David, the owner and lead technician, oversees the work that goes out under our name. We have a real storefront at 10740 Wilshire Blvd in Westwood, and our mobile service vans cover 140 cities across Los Angeles and Ventura counties, Valencia included. When you call, you reach us, not a dispatch broker who sends the job to whoever picks it up.
That matters for car keys in particular. Key programming is the part of locksmith work where shortcuts show up later, as a key that works for a week and then fails, or a remote that never quite pairs. We would rather tell you what a job needs and be honest about what we cannot do than rush to a yes.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith for it before they start work on your car. A company that is reluctant to answer is telling you something.
We answer 24 hours a day, 7 days a week, all year, at (213) 577-1366. If you prefer, you can also use our contact page to send the details of your vehicle ahead of time.
Frequently asked questions
Can you make a car key if I have lost every key?
In many cases, yes, and we do it at your vehicle. It takes more steps than copying an existing key, and the exact process depends on the car. We confirm the vehicle by VIN, check your ID and proof of ownership, and tell you up front if your car is one that only a dealer can handle.
What is the difference between a spare car key and a replacement car key?
A spare is made while you still have a working key, so it is generally the lighter-cost route. A replacement is made after the keys are gone, which means the car has to be set up to accept a new key from scratch. Same end result, different amount of work.
Do I need to bring my car to a shop?
No. Our vans carry the cutting and programming equipment and come to the car, whether it is in a driveway, a parking structure, or on the street in Valencia. If we find something that requires a shop or the dealer, we say so before starting.
What do I need to show you to get a new car key?
Photo ID and proof that the vehicle is yours, such as the registration or title with a matching name. We ask this every time, and it protects you as much as anyone, since it keeps strangers from getting keys to cars they do not own.
Can you do same day car key replacement in Valencia?
Often we can, depending on the vehicle, the type of key, and whether the blank is on the van. Call (213) 577-1366 at any hour and tell us the year, make, and model. We will tell you honestly whether it can be done from the van or needs another step.
Will a duplicate car key work with my remote buttons?
It can, but remote functions are programmed separately from the key's ability to start the car. Tell us whether you want the buttons working. For separate remotes, see our key fob replacement service.
Why will my key not turn in the ignition?
It could be a worn key, a worn or dirty ignition cylinder, or both. We look at it before cutting anything, since a new key copied from a worn one may not fix the problem. If the ignition itself is failing, that is a separate repair.
Is it cheaper to go to the dealer or a locksmith?
It depends on the vehicle, and we will not claim it is always one or the other. For many cars, a mobile locksmith is the more economical route and saves the tow. For some vehicles, the dealer is the only option, and we will tell you that honestly when we confirm by VIN.
How do I know a locksmith is legitimate?
Ask for their BSIS LCO license number, which California requires of locksmith companies. Ask whether they will show up in a marked vehicle, and whether they ask for ID and ownership proof. A company that does not ask for proof before making a car key is worth avoiding.
