What does car key replacement actually cover?
Car key replacement is a catch-all phrase for several different situations. You might have lost every key to the car. You might still have one good key and want a spare. You might be holding a key that is worn smooth, bent, or cracked and could fail any day. Or the metal part might be fine while the remote buttons have gone dead. Each one starts with the same question: what does this particular vehicle need before it will unlock and start?
Most keys made in recent decades are really two parts in one. There is a metal blade that turns the locks, and there is an electronic part the car checks before it lets the engine run. Cutting the blade is the easier half. Getting the car to accept the new key is the half that takes the right equipment and the right information for your vehicle. That is why a copy from a hardware kiosk sometimes opens the door and then refuses to start the car.
This page is about cutting and programming a new key, whether it is a spare, a duplicate, or a replacement for one that is gone. A few neighboring problems have their own pages:
- If every key is gone and you are starting from nothing, see lost car key replacement.
- If the key is fine but the remote has quit, see key fob replacement.
- If a key snapped off in a lock or the ignition, that is a job for broken key extraction.
- If the key goes in but the ignition will not turn, the cylinder may be the problem, which is covered under ignition repair.
Is it smarter to make a spare car key now than replace one later?
Almost always, yes. A spare car key made while you still have a working key is usually the more economical route, and it is far less stressful. With a working key in hand, the job starts from something the car already recognizes. With no keys at all, the work starts from the vehicle itself: identifying the correct key, getting the cut information, and programming from scratch. That takes more steps and costs more in nearly every case.
A duplicate car key is a copy made from an existing key. A spare car key is simply the extra one you keep somewhere safe. In practice they are the same job, and we treat them that way. What matters is that the spare actually starts the car and lives somewhere other than your own pocket or the glove box.
Where you keep it matters too. Montebello summers run hotter than coastal Los Angeles, and a parked car gets very hot inside, which is a poor home for a key with a battery and a plastic housing. A key left in the car is also a key someone else can find. Keep the spare indoors or with someone you trust. And if you are down to one key right now, that is the moment to call, not after it disappears.

Call (213) 577-1366How do we replace a car key, step by step?
Every vehicle is a little different, but the process is consistent. Here is what happens when you call (213) 577-1366.
- You tell us the make, model, and year, and what you have: no keys, one key, a broken key, or a remote that quit. If you can read us the VIN, that helps. It is usually visible at the base of the windshield on the driver's side and on the driver's door jamb.
- We confirm the key type for your car by VIN or in person rather than guessing from a model name. Equipment can differ between years and trims, so we do not assume.
- We tell you plainly whether the job can be finished on site or whether your vehicle is a dealer-only case. If it is dealer-only, you hear that on the phone, before anyone drives out.
- We verify ownership. Expect to show ID and proof the car is yours, such as registration or title. A locksmith who skips this step is one to be careful with.
- We do the car key cutting, either by code from the vehicle information or from your existing key, depending on your situation.
- We program the key to the car and, if it has remote buttons, set up the remote functions too.
- We test it the way you will actually use it: door lock and unlock, trunk if the car has a separate one, ignition, and every remote button. You leave knowing it works.
Can you do mobile car key replacement in Montebello on the same day?
In many cases, yes. We answer the phone 24 hours a day, seven days a week, and our mobile locksmith vans are set up to cut and program keys on site, so the work happens at your car, in your driveway or parking space, rather than at a counter. For a lot of vehicles, same day car key replacement means a single visit from start to finish.
We will not promise that every vehicle can be done in one trip, because that would not be true. A few situations push a job past same day: a key blank that has to be ordered for an unusual vehicle, a car where the programming is restricted to the dealer, or a vehicle we cannot identify properly until we see it. When any of those apply, we say so and walk you through your options, which may include the dealer. We would rather tell you up front than leave you waiting.
Montebello is about 21 miles from our Westwood storefront, so for most customers here the van comes to you. The storefront at 10740 Wilshire Blvd is there if you would rather bring the car in or handle a key in person.

Call (213) 577-1366What kind of key does your car use?
Knowing the key type is half of getting a plan and a fair explanation of cost. Broadly, car keys fall into a few groups, and which one your vehicle uses depends on make, model, and year:
- Plain metal keys: a cut blade with no electronics. Simple to copy, and found mostly on older vehicles.
- Transponder keys: a cut blade plus an electronic part the car must recognize before the engine will run. These need programming, not just cutting.
- Remote head keys: the blade and the lock and unlock buttons share one housing.
- Smart or proximity keys: a fob that lets the car unlock and start without a blade going into a lock, usually with a hidden emergency blade inside.
- Milled or high-security blades: a thicker blade cut on its face rather than its edges, which calls for different cutting equipment.
Why we confirm by VIN instead of quoting from memory
We do not recite chip or programming details for specific models off the top of our heads, because they change between years and trims, and a wrong guess costs you time. We confirm by VIN or in person. Our transponder key programming page goes deeper on how the electronic side works.
One more thing worth knowing: the ignition key and the door key are usually the same key, but not always. Some vehicles come with a separate valet or door-only key, so tell us which one you need. If your ignition key replacement is needed because the key no longer turns the ignition, the problem may be the ignition cylinder rather than the key, and we check that before cutting anything.
What affects the price of a replacement car key?
We do not post a flat price, because a car key is not a flat-price item. The same words, replace my car key, can describe a short job or a long one. These are the things that move the cost:
Because we confirm the vehicle first, you hear what applies to your car and why before work starts. As a rule, a spare made from a working key is the more economical path. If a dealer is an option for your car, it is worth comparing the whole picture, including how the car would get there, not just the key itself.
- Key type: a plain metal key, a transponder key, and a smart key are very different jobs.
- Whether you still have a working key to copy from, or are starting from nothing.
- Vehicle make, model, and year, since some need more involved programming than others.
- Whether the programming can be done on site or is restricted to the dealer.
- How many keys you need made in the same visit.
- Blade style, such as standard edge-cut versus milled.
- Whether remote or smart key electronics must be replaced along with the blade.
- Time of day and urgency: a late-night call involves different effort than a planned daytime visit.

What does car key replacement look like around Montebello (90640)?
Montebello is covered by a single ZIP, 90640, but the places people lose or break keys are quite different, and that shapes how the job goes.
In the condo and apartment corridors along Garfield Avenue and Beverly Boulevard, many cars are parked in shared lots or on the street. If your only key goes missing there, the car is not going anywhere, so the key has to come to the car. That is exactly the situation mobile service exists for, and it is a good reason for residents in those buildings to keep a programmed spare indoors rather than relying on a single key.
In South Montebello, where many homes are 1920s Spanish-style bungalows, and in North Montebello, where postwar ranch tracts are common, the job is the same: we come to wherever the car is parked. Up toward the Montebello Hills area, streets sit on sloped lots with longer driveways, so when you call, tell us where the car is and how we get to it.
Retail and commercial areas bring their own version of the problem. If you lose a key while shopping in the Town Center area near The Shops at Montebello, or you are working along the Whittier Boulevard corridor, you are stuck wherever you parked. Give us the lot or the cross street and we will come to the vehicle. If the missing key belongs to a vehicle a business depends on, say so when you call so we can plan the visit around that.
How do you know a car locksmith is legitimate?
California requires locksmith companies to hold a Locksmith Company (LCO) license from the Bureau of Security and Investigative Services, known as BSIS. Ask any locksmith for that license number before work begins. A real company will give it to you without fuss.
A few other signs are worth watching for. A legitimate locksmith asks for proof of ownership before making a car key, identifies the key type before explaining cost, has a real address, and gives you a straight answer about whether your car is a dealer-only case. Be careful with anyone who quotes a suspiciously low number sight unseen and then changes it at your car door.
Frequently asked questions
How much does car key replacement cost in Montebello?
It depends on the key type, whether you still have a working key, your vehicle's make, model, and year, how many keys you need, and whether the programming can be done on site. After-hours calls also involve different effort than a daytime visit. Call (213) 577-1366 with your vehicle details and we will explain what applies to your car before any work starts.
Can you make a car key if I have lost every key?
Often, yes. We work from the vehicle's VIN and your proof of ownership instead of an existing key, which usually takes more steps than copying a working key. Some vehicles are dealer-only in that situation, and we confirm by VIN which category yours falls into.
Do I have to bring my car to you?
No. Most of the time we come to you in Montebello with a mobile van and cut and program the key on site. Our storefront at 10740 Wilshire Blvd in Westwood, about 21 miles away, is available if you would rather bring the car in.
Is a duplicate car key the same as a spare car key?
Practically, yes. A duplicate is a copy made from a key you already have, and a spare is the extra key you keep as a backup. Either way, the goal is a key that unlocks the doors and starts the car, which is why we test every function before we leave.
What do I need to show you before you make a key?
Photo ID and proof the vehicle is yours, such as registration or title. The VIN also helps us confirm the correct key. We ask for ownership proof on every car key job, and you should be wary of any locksmith who does not.
Will my old key still work after you make a new one?
That depends on the vehicle, and we confirm it for your specific car rather than give a blanket answer. If the lost key could be in someone else's hands, tell us when you call so we can talk through the options for your vehicle.
I am locked out with my keys inside the car. Is that the same service?
Not quite. If your keys are inside and you just need the door opened, that is a car lockout call. If the keys are truly gone, you need a replacement. Call (213) 577-1366 and we will sort out which one applies.
Can you cut a car key at night or on a weekend?
Our phone is answered 24 hours a day, 7 days a week, year-round. Whether a particular key can be finished during that same visit depends on the vehicle, and we tell you honestly if a part has to be ordered or your car is a dealer-only case.
Do you replace keys for every make of car?
We handle a wide range of vehicles, but we will not promise every make, model, and year without checking. Give us the make, model, year, and VIN if you have it, and we will tell you plainly whether we can do the job or whether the dealer is your only route.
