What is car key replacement, and when do you need it in Mission Hills?
Car key replacement means making a new, working key for your vehicle when the original is gone, broken, or worn out, or when you only have one key and want a second. In Mission Hills we do this from a mobile service van, so the cutting and programming happen where your car is parked. You do not have to arrange a tow just to get a key made.
Most calls we get fall into a handful of situations:
- You lost your only key and cannot start or move the car.
- You have one working key and want a spare car key made before something goes wrong.
- Your key is bent, worn smooth, or cracked, and it is getting harder to turn in the ignition.
- The key snapped, or part of it is stuck in the lock or ignition.
- The remote buttons on your key or fob quit working.
- You bought a used car that came with a single key and want a duplicate.
Spare key or all-keys-lost: why the difference matters
If you still have one working key, making a duplicate car key is usually the simpler job. We can read the existing key and copy it, and the car can often be programmed to accept the new one with the original present. If every key is gone, the work is different: a key has to be made from the vehicle's information rather than copied, and the car's system often has to be set up to recognize the new key. That generally takes more time and equipment.
This is the honest reason we tell people to make a spare while they still have a key in hand. It is usually the more economical route, and it means a lost key is an inconvenience instead of an emergency. If you are already in the all-keys-lost situation, our page on lost car key replacement goes into that scenario in more detail.
How does mobile car key replacement work, step by step?
Every vehicle is a little different, but the process on a typical job looks like this.
- You call (213) 577-1366. Someone answers at any hour, any day of the year. Tell us the make, model, and year, where the car is, and whether you have any working key at all.
- We ask for the VIN, which is usually visible through the windshield at the base of the driver's side, and on your registration or insurance card. The VIN lets us confirm the exact key type your car uses instead of guessing.
- We tell you plainly what the job involves for your vehicle: key type, whether we can do it on site, and what drives the cost. If your car is one that has to go to a dealer, we say so up front.
- A technician drives the van to you, whether that is a driveway, an apartment lot, a workplace parking space, or the roadside.
- We confirm you are the owner or authorized user of the vehicle. This is a standard part of the work, and a reputable locksmith will ask.
- We cut the key to code or by duplicating your existing key, then program it so the car recognizes it and, where applicable, the remote functions work.
- You test the new key before we finish: door locks, ignition, remote buttons, and starting the engine. If something is not right, we fix it while we are still there.

Call (213) 577-1366Which types of car keys can we cut and program?
We work on the main kinds of automotive keys. What your car actually needs depends on its make, model, and year, and we do not rely on assumptions. We confirm by VIN, and when needed in person, before we promise a specific outcome.
The kinds of keys we are typically asked about include:
- Traditional metal-only keys, cut to fit the locks and ignition.
- Transponder keys, where the key communicates with the car before it will start. See our page on transponder key programming for how that part works.
- Remote-head keys, which combine the blade and the lock/unlock buttons in one piece.
- Key fobs and proximity-style remotes. Our key fob replacement page covers those.
- Replacement keys for worn ignitions, where the key itself is only part of the problem.
Are there cars we cannot do on site?
Yes, and we would rather say so than leave you waiting. Some vehicles, including certain newer models and some brands, have security systems that restrict key creation to the dealer or require information only the dealer can provide. When your VIN tells us your car is one of those, we tell you right away, so you can decide what to do instead of paying for a visit that cannot solve the problem.
In other cases the information is unclear or sources disagree about a specific model year. We do not guess in those cases. We confirm by VIN and in person, and then give you a straight answer.
What affects the cost of car key replacement?
We do not publish flat numbers for car keys because the real cost depends on your specific vehicle. Anyone who quotes a single figure before knowing your car is guessing, or planning to adjust it later. Here is what actually moves the cost:
- The type of key: a basic cut key is a different job from a transponder key, a remote-head key, or a proximity fob.
- Make, model, and year: the key hardware and the programming steps vary widely between manufacturers and between model years.
- All keys lost versus a spare: copying from a working key is usually less involved than creating a key from scratch.
- The key blank or fob itself: some are widely available, others are specific to a vehicle.
- Programming requirements: some cars take a quick procedure, while others need more equipment and time.
- Cutting method: some keys are cut by edge, others by a milled channel in the blade, and the machine and time needed differ.
- Condition of the ignition or locks: if a worn ignition is damaging keys or refusing to turn them, that may need separate attention.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366How do you keep the price reasonable?
The lighter-cost approach is almost always to make a spare before you are stranded. After that, the best thing you can do is give us accurate information up front: the VIN, what keys you still have, and where the car is. That lets us quote the real job, not a range that covers every possibility. We give you the cost for your vehicle before we start the work.
Can you do same-day car key replacement?
We answer the phone around the clock, and for many vehicles a replacement can be completed in a single visit, because the cutting and programming equipment travels with us. We do not promise a specific arrival time, because it depends on where our vans are, traffic, and what your car needs. What we will do is tell you honestly what is realistic when you call.
Same-day work is most likely when your key type is common enough for us to have or source the blank quickly. If your car needs a specific part we do not have on the van, we tell you that on the phone and explain the next step. More about how our vans work is on our mobile locksmith page.
If your problem is that the key will not turn at all, or it turns but the car will not start, the issue may be the ignition and not the key. We would rather diagnose that correctly than cut you a new key that fails the same way. That is a separate job, covered under ignition repair. And if a piece of the key is broken off inside, see broken key extraction.
Car key replacement around Mission Hills: where we get called
Mission Hills, ZIP code 91345, is a north-valley neighborhood that sits about 17 miles from our storefront at 10740 Wilshire Blvd in Westwood. Our mobile vans cover it as part of our service across 140 cities in Los Angeles and Ventura counties.
Here is how car key situations tend to look across the neighborhood's different parts:
Along the Sepulveda Boulevard corridor, apartments are concentrated. If you live in one, your car key and your apartment key are often on the same ring, so losing the ring means two problems at once. We handle the car side, and if you are locked out of your unit too, our apartment lockout page covers that. Many residents in this kind of building park in a shared lot, and we come to wherever the vehicle is.
Around the Mission district near San Fernando Mission, and in the 1950s ranch-style tracts nearby, most people park in a driveway or on the street. A mobile visit works well here, since the work happens at the curb or in the driveway.
Along the Devonshire Street corridor and near the I-405/SR-118 interchange area, people are often commuting or working when a key goes missing. If you realize at the end of a shift near Providence Holy Cross Medical Center that your key is gone, a call to us lets you stay with your car instead of arranging a tow.
Mission Hills also runs hotter in summer than the basin, according to our local data. Heat is hard on plastic key cases and remote batteries over time, so if your fob has started acting up, that is a good moment to get a spare made before it quits entirely.

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. We are one company with a real storefront in Westwood and our own mobile vans. When you call (213) 577-1366, you are not routed through a dispatch middleman who passes your job to whoever is available. For the full picture of what we do for vehicles, see our automotive locksmith page.
One more thing worth knowing: California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for their license number before work begins. A legitimate company will give it to you without hesitation.
What should you have ready when you call?
A few details speed things up considerably. You do not need all of them, and we can work with what you have.
- The make, model, and year of the vehicle.
- The VIN, from the windshield or your registration or insurance card.
- Proof that the car is yours, such as registration or ID that matches.
- Any remaining keys, even one that is damaged or does not work well.
- The exact location of the car, including a parking space or nearby cross streets.
- Whether the car currently starts, and whether the remote works.
Frequently asked questions
Can you make a car key without the original?
In many cases, yes. When every key is lost, we create a new key from your vehicle's information and set up the car to recognize it. Whether that can be done on site depends on the vehicle, and we confirm by VIN. A few cars are dealer-only, and we tell you honestly if yours is one.
How much does car key replacement cost in Mission Hills?
It depends on your key type, the make, model, and year, whether you have a working key to copy, and what programming your car requires. We do not quote numbers without knowing the vehicle. Call (213) 577-1366 with your VIN and we will give you the cost for your car before we begin.
Is it cheaper to make a spare than to replace a lost key?
Copying a working key is generally the more economical route, because it is less involved than creating a key when all keys are lost. We cannot give a number without your vehicle details, but making a spare before you need one is the lighter-cost option.
Do you come to me, or do I bring the car in?
We come to you. Our mobile vans carry cutting and programming equipment, so most work is done where the car is parked in Mission Hills. We also have a storefront at 10740 Wilshire Blvd in Westwood.
Do I have to go to the dealer for a new key?
Not always. Many vehicles can be handled by a locksmith on site. Some cars, depending on make, model, and year, restrict key creation to the dealer. We check your VIN and tell you at the start whether yours can be done by us.
Can you replace a key if I am locked out of my car too?
Yes, that is a common combination. Getting you back into the vehicle is a separate task from making the key, and we handle both in one visit when we can. Our car lockout page explains that service.
Will the new key work with my remote and door locks?
That is what we test before we leave. We program the key where your car requires it and check the door locks, ignition, remote buttons, and engine start together. If a feature does not work, we address it while we are still on site.
Do you offer service at night and on weekends?
Yes. Our phone line, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round. Whether a given key can be finished that same visit depends on your vehicle, and we tell you honestly when you call.
What do I need to prove the car is mine?
We ask for identification and something showing ownership or authorized use, such as the registration or insurance card that matches the VIN. It protects you as the owner, and any reputable locksmith should ask for it.
