What does car key replacement in Pasadena actually involve?
Car key replacement means making a new key that starts and unlocks your specific vehicle. On an older car that can be a simple cut. On most newer cars it is two jobs: cutting the metal blade to match your locks, and programming the electronic part so the car's computer accepts it. Some keys only need one of those, and some need more, which is why the first question we ask is always about the car itself.
People call us about a handful of situations. They have lost the only key. They have one key and want a spare before something happens to it. A key has snapped, worn smooth, or started to stick in the ignition. Or a remote has stopped working and they need to know whether it is the battery, the key, or something else. Each of these is a different job with a different level of urgency, and treating them all the same is how people end up paying for work they did not need.
This page covers making new keys and spares for your vehicle. If your problem is a locked car with the key inside, that is a different job, covered on our car lockout page. If the key is physically broken off in a lock or ignition, that is handled as broken key extraction first, and a new key comes after.
Which situation are you in: spare key, duplicate, or all keys lost?
The situation decides how the job goes, so it helps to know where you stand before you call. Here is how we think about the three common cases.
- You still have a working key and want a spare car key or duplicate car key. This is the easiest and usually the more economical route. We can copy from the existing key and program the new one, and nothing about your car is in a rush.
- You have a working key but it is worn, cracked, or unreliable. Replace it before it fails. A worn key can damage ignition wafers over time, and the sooner you make a fresh one, the less likely you are to end up stranded.
- You have no working key at all. This is the all-keys-lost case. There is no existing key to copy, so the key has to be generated from the vehicle itself, using its lock cipher and its computer. It takes more steps and more equipment, but it is routine work for us and it does not require towing the car in most cases.

Call (213) 577-1366How does mobile car key replacement work, step by step?
Mobile car key replacement means we bring the equipment to the car instead of the car going to a shop. Our vans carry key-cutting machines, programming tools, and a stock of key blanks and remote shells. Here is the order we follow on a typical call.
- You call (213) 577-1366 and tell us the make, model, year, and where the car is parked. Tell us how many working keys you have, even if the answer is none.
- We tell you plainly whether your vehicle is something we can do on site, what type of key it uses, and what the job will depend on. Where we are unsure about a specific model, we say so and confirm by VIN rather than guess.
- We send a mobile technician to the car. You will need to show you own it or are authorized to use it, such as with registration and photo ID. We ask for this on every automotive job, and it protects you as much as anyone.
- We confirm the key type against your VIN and the car itself, then cut the blade to match your locks. If there is no key to copy, we cut from the lock or from code information for the vehicle.
- We program the new key to the car's system, and add or remove other keys when needed. If you have lost a key, we can often clear the lost one from the car's memory so it no longer starts the engine.
- We test everything before we leave: turn the ignition, lock and unlock, run any remote buttons, and check the trunk and door locks. If something does not work, we sort it out while we are standing there.
What kinds of car keys can we replace and program?
Keys fall into a few broad families, and knowing which one you have makes the call faster. The same make and model can use different key types depending on the year, so we treat these as general categories rather than promises about any one car.
Plain metal keys with no electronics only need cutting. Transponder keys have a chip inside the head that the car must recognize before the engine will run, so they need programming as well as cutting. Remote-head keys combine the blade and the lock/unlock buttons in one piece. Smart or proximity keys let the car start with a push button while the key stays in your pocket, and they are programmed differently from blade keys.
We cover chip-key work in more detail on our transponder key programming page, and remotes and smart keys on the key fob replacement page. If the real problem is a worn ignition cylinder that will not turn even with a good key, that is an ignition repair job, and replacing the key alone will not fix it.
A note on honesty: not every vehicle can be done by an independent locksmith. Some makes and model years lock key programming behind manufacturer-only access, and for those the dealer may be the only route. Information on which vehicles fall into that group is not always consistent, so we do not recite a list from memory. We check by VIN, and if your car turns out to be a dealer-only case, we will tell you that on the phone instead of sending a van out for nothing. Ignition key replacement is the same story: it depends on whether the issue is the key, the cylinder, or the car's computer.

Call (213) 577-1366How much does car key replacement cost in Pasadena?
We do not quote prices on a web page, because the honest answer depends on the car. Here is what moves the cost, so you can judge any quote you get, ours included.
The biggest factor is the key type. A plain cut key is a smaller job than a transponder key, and a transponder key is a smaller job than a smart key. Parts matter too: a blank for one model can be easy to stock, while another has to be sourced.
Second is whether you have a working key. Copying from an existing key is simpler than building one from scratch in an all-keys-lost situation. That is why a spare car key made now is usually the more economical route compared with waiting until the last key disappears.
Third is the vehicle itself: make, model, year, and how its security system handles new keys. Some cars accept a new key in one routine session, and others take longer or need extra steps.
Finally, there is where and when you call. A visit to a car in a Pasadena parking structure at midday is a different trip from a late-night call to a lot with no easy access. Our phone line is answered around the clock, and we will explain how these factors apply to your car before we start work, so the number you hear is tied to a specific job.
- Key type: cut-only, transponder, remote-head, or smart key
- Existing key available or all keys lost
- Make, model and year, and how the car handles new keys
- Number of keys needed in one visit
- Time of day and access to the vehicle
Is same day car key replacement realistic?
For many vehicles, yes: we cut and program on site, so there is no need to wait for a part to ship from somewhere else. A same day car key replacement is a common outcome when the blank is something we carry and the car accepts programming from an independent tool.
It is not something we can promise for every car. If your key needs a blank we have to order, or if the vehicle falls into the dealer-only group, the timeline changes, and we will tell you so when you call. We would rather give you a straight picture than a promise we cannot keep.
What speeds things up on your end: have the VIN ready (it is on the dashboard near the windshield and on the driver door jamb sticker), your registration and ID, and the car parked somewhere we can reach. If the key is lost, retrace your steps first. A quick look in the last place you parked sometimes solves it, and no one at our company will mind if you find the key before we show up.

Call (213) 577-1366Why call Wilshire Lock & Key for your car keys?
We have been in business since 1987. That is a long time to see how car locks and keys change, and it means the person answering your question has handled this kind of job before. David, the owner and lead technician, oversees our work, so automotive jobs are not handed off to a stranger who has never met us.
We are one company with a storefront at 10740 Wilshire Blvd in Westwood and our own mobile service vans. There is no dispatch middleman between you and the technician, no call center reselling your job to whoever picks it up. When you call (213) 577-1366, you reach us, any hour of any day.
Some practical advice whether you use us or not: California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for it before they begin, and be wary of anyone who dodges the question. Also be careful with listings that show a local-looking name but send an unknown subcontractor. Ask who is coming, what they will do, and what the job depends on. A decent locksmith will answer all three without fuss. We are happy to explain our process to you, which you can also read about on our automotive locksmith page.
Car key replacement around Pasadena: where we work and what comes up
Pasadena is about 23 miles from our Westwood storefront, and we serve the whole city across ZIP codes 91101, 91103, 91104, 91105, 91106 and 91107. Car key jobs here tend to follow how people live and park.
In the dense core around Old Pasadena, the Playhouse District and Lake Avenue, many people live in mid-rise condos and apartments, and parking is often in a shared lot or structure. A lost key in a place like that is still a car key job, but access matters: if the garage is controlled, we coordinate with you so we can get the van to the car, and it is worth having your building's access details on hand when you call. Controlled-access buildings are especially common along the Metro A Line corridor.
Farther out, in neighborhoods like Bungalow Heaven, Oak Knoll, San Rafael, Hastings Ranch and Linda Vista, cars usually sit in driveways or on the street, which makes mobile work straightforward. We cut and program at the curb or in the driveway.
Event days bring their own pattern. When the Rose Bowl Stadium fills up, car trouble in the lots is not unusual, and so are the lots at Brookside Park. If you have lost a key during an event and the car is parked in a crowded lot, call us and tell us your exact location and row or landmark. The car lockout side of that is a separate service, but a key lost or left behind can easily turn into both problems at once.
The campus areas near Pasadena City College and Caltech are another place people call. A student or staff member who owns one key and wants a duplicate car key before a long semester is doing exactly the right thing. We can meet you where the car is parked, whether that is near campus, near Huntington Hospital, or along Colorado Boulevard.
On climate: Pasadena runs hotter than coastal Los Angeles in summer, and if you are standing next to a car you cannot start, that heat matters. It is one more reason we prefer to make the visit efficient: have your VIN, ID and registration ready, and we can get to work as soon as we reach the car. Our mobile locksmith page explains more about how the vans operate across the city.

Call (213) 577-1366How to avoid a lost-key emergency in the first place
Most all-keys-lost calls could have been a spare-key visit if someone had acted a few weeks earlier. The ordering is simple: a spare made while you still have a working key is generally less involved than rebuilding access from nothing.
Make at least one spare, and keep it somewhere that is not the car. A hide-a-key box on the vehicle is a bad idea, since thieves know the habit. Keep the spare with a family member, or at home in a spot you can reach.
If a key is cracked, the blade is worn, or the remote buttons are failing, replace it now. A key that works only when you jiggle it is on a schedule you do not control.
If you lose a key, tell us whether it might be in someone else's hands. When the missing key could be in the wrong place, we can often program the car to reject it, which is a good reason to treat a lost key as more than a convenience problem.
Finally, keep the VIN and your registration somewhere easy to find. That is the single most useful piece of information when you call, and it takes a minute to photograph and save on your phone.
Frequently asked questions
Can you make a car key if I have lost all my keys?
In most cases, yes. With no key to copy, we generate one from the vehicle itself and program it on site. The details depend on your make, model and year, and we confirm by VIN before we start. Some vehicles are dealer-only for programming, and if yours is one of them we will say so on the phone. Our fuller explanation is on the lost car key replacement page.
Do I need to prove I own the car?
Yes. We ask for photo ID and proof of ownership or authorization, such as registration or title, before making a key for any vehicle. It protects you from someone else getting a key to your car, and it is a normal part of automotive locksmith work.
Is a spare car key cheaper than a replacement?
Generally a spare made while you still have a working key is the more economical route, because we are copying from an existing key rather than building access from scratch. The final cost still depends on key type and the vehicle, so we explain it before starting.
Will you come to me in Pasadena, or do I need to bring the car?
We come to you. Our mobile vans carry cutting and programming equipment, so we can work in a driveway, street, parking structure or lot anywhere in Pasadena. We answer calls 24 hours a day, 7 days a week at (213) 577-1366.
How long does a car key take to make?
It depends on the key type and the car. Many jobs are completed in a single visit, but we do not promise a fixed time, because a smart key on one vehicle can take far longer than a basic transponder key on another. We tell you what to expect once we know your vehicle.
Can a locksmith program a key for any car?
No, and anyone who says yes is oversimplifying. Many vehicles can be done by an independent locksmith, but some makes and years require dealer-only access for programming. Where information is unclear, we check by VIN or in person and are upfront if a dealer is the only route.
What information should I have ready when I call?
Your vehicle's make, model, year, and VIN if you can find it. Tell us how many working keys you have, where the car is parked, and what type of key you use, such as a plain key, a push-button start, or a remote. Have your ID and registration ready for the visit.
Will the old lost key still start my car after you program a new one?
Often we can remove the lost key from the car's memory so it will no longer start the engine, but that depends on the vehicle. It is worth raising when you call, especially if the key may have been stolen rather than just misplaced.
