What does lost car key replacement mean when you have no original?
It means exactly what it sounds like: every key to the vehicle is gone, and nothing exists to copy. A copy machine is no help here. Someone has to build a new key from the vehicle's own information and then make the car accept it. That is a different job from duplicating a key you are holding, and it is a different job from a simple lockout.
If you are standing in a parking lot in Monrovia wondering whether a replacement car key without the original is even possible, it is. It is routine work for an automotive locksmith. The details depend on the vehicle, and we will be straight with you about which details apply to yours.
This page covers the all-keys-lost situation only. If you still have one working key and just want a spare, that is a lighter job, and you can read about it under key duplication. If your keys are visible inside the car and you only need the door opened, that is a lockout, not a replacement.
Lost all car keys in Monrovia: what you are actually dealing with
When the last key disappears, three separate problems usually stack up. First, you may not be able to get into the vehicle. Second, even once you are inside, the car will not start without a key it recognizes. Third, the old key is still out there somewhere, and if it was lost along with a wallet or something with your address on it, you may want to think about who could pick it up.
That third point matters more than people expect. If you dropped the key in a public place, a replacement job is a good moment to ask whether the lost key should still be able to start your car. Depending on the vehicle, the newly programmed key set can be arranged so the old one no longer works. We will tell you whether that applies to your car when we confirm the details.
Most people calling about lost car keys have had a rough hour already. They have retraced their steps, checked coat pockets, called the restaurant, looked under the seat of a different car. That is all worth doing, and we cover a short checklist below. But if you are past that point, the next step is a phone call, not another lap around the block.
How do we make a new car key without the original?
Every vehicle is a little different, so this is the general order of work rather than a script. We adjust it once we know your make, model and year.
- You call (213) 577-1366, any hour. We ask where the vehicle is, its make, model and year, and whether it is locked, unlocked, or running into some other problem. The VIN, which is visible through the windshield on most vehicles, helps a great deal.
- We explain the route for your vehicle: whether we can cut and program on site, whether any part of the job points to a dealer, and what will affect the cost. You decide before any work starts.
- We arrive in a mobile van. If the car is locked, we open it first without damaging the door or the lock. That is the same skill set described on our car lockout page.
- We confirm you are the person entitled to the vehicle. We will ask for ID and some proof of ownership or registration that matches. This protects you, and it protects whoever really owns the car.
- We identify the key blank and the code information the vehicle needs, then cut a new key from that information rather than from an original.
- If the vehicle needs electronic programming, we program the new key to the car and test it: unlock, start, and run. The programming side is explained further at transponder key programming.
- We make sure every key we cut or program works the way it should before we pack up. If you want a second key made while we are there, that is far easier at this stage than after we leave.

Call (213) 577-1366Can a locksmith really replace a car key without the original?
Yes, for the large majority of vehicles on the road. The key does not have to exist for a new one to be made. What has to exist is a way to get the key's cut information and a way to introduce a new key to the car's security system. Both can be done on site with the right equipment, and that equipment lives in our vans.
Whether your key is a plain metal blade, a key with a chip inside, a remote-head key, or a push-button-start fob changes the work involved. We do not guess at which one your car uses from the model name alone. We confirm by VIN and in person, because the same model can be built differently from one year to the next, and anyone who promises exact details over the phone without checking is guessing.
If your car uses a fob rather than a traditional key, the work overlaps with what we describe on the key fob replacement page. And when the problem is not the key but the ignition itself, such as a cylinder that is worn or damaged, that is a separate repair covered under ignition repair.
When is the dealer the only option?
We would rather tell you this up front than have you find out halfway through. Some vehicles, and some key types, are restricted. A few manufacturers lock down certain keys so tightly that only the dealer can supply the key or the code needed to produce one. In those cases we say so, plainly, and we do not start work that cannot be finished on site.
Sometimes a vehicle can be handled by either route, and the choice comes down to practical things: where the car is, whether it can be moved, how long you can be without it, and what you want to spend your day doing. A dealer visit usually means getting the vehicle there, which may mean a tow if you have no key to drive it. Coming to the vehicle is the point of a mobile locksmith, and you can read how that works on our mobile locksmith page.
If your car turns out to be dealer-only, we will tell you during the first call or when we check the VIN, and we will not charge you for a job we could not do. If we are not sure, we say we are not sure, and we find out before you commit to anything.

Call (213) 577-1366What affects the cost of replacing a lost car key?
We do not quote numbers on a web page, because an honest number depends on facts we do not have yet. Here is what moves the cost, so you can see why two cars in the same parking lot can end up with very different bills.
Quoting you a figure only after we know these things is how we keep the number honest.
- The type of key. A simple metal key is a lighter job than a chip key, which is lighter than a smart key or push-button-start fob.
- The vehicle's make, model and year. Some brands are straightforward to work on and some demand more time and more specialized equipment.
- Whether the vehicle is locked. Getting in safely is its own piece of work.
- How many keys you want. Having us make a spare during the same visit usually costs less than calling us back another day.
- Where and when you need us. A night or holiday call, or a location far from our storefront, affects the total.
- Whether the ignition or lock hardware is damaged. A worn or broken cylinder changes the plan, sometimes the entire plan.
- Whether the vehicle is a dealer-only case. If it is, we say so before you spend anything.
- The usually more economical route is almost always the mobile one, because it removes towing and a dealer visit from the bill. But whether that applies to your car depends on the points above, and we will tell you straight.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and that is long enough to have seen most of the ways a car key can go missing: dropped in a shopping center, left on a trail, locked inside with the engine off, or simply gone with no explanation. We work from a storefront at 10740 Wilshire Blvd in Westwood, and our mobile vans come to you across 140 cities in Los Angeles and Ventura counties, including Monrovia.
When you call (213) 577-1366, you reach us, a single company, not a call center that passes your job to whoever answers a dispatch app. David, the owner and lead technician, oversees how the work is done. That matters in a job where the technician has your car, your ID check and your security in their hands.
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 you are thinking of hiring for it, including us. It is a fair question and a good way to screen out the operators who answer the phone with a generic business name and show up in an unmarked car.
You can also browse our wider automotive locksmith work if your situation is bigger than a single lost key, or if you want to know what else we do for vehicles.

Call (213) 577-1366Lost car keys around Monrovia: neighborhoods, 91016 and real situations
Monrovia sits in the foothills of the San Gabriel Valley, and we are about 29 miles from the Westwood base to get here. That distance is the honest reason we ask for your exact location on the first call. Everything we plan, including the route and what we bring, starts from where your vehicle is parked.
Take Old Town Monrovia along Myrtle Avenue. It is the kind of place where you park, walk to dinner or a shop, and realize on the way back that your keys are not in your pocket. If the car is on the street or in a lot near Library Park, we come to it. The same goes for the Huntington Drive and Foothill Boulevard corridors, where people often leave a vehicle for a few hours and expect to come back to it.
Hiking is the situation that fits Monrovia best. People drive up to Monrovia Canyon Park, leave the vehicle in the lot, and head out on a trail. If you come back to the lot and the keys are gone, a pocket has been emptied somewhere along the route, or the keys fell out of a pack. In summer the foothills are hot, and standing around a parked car with no key is not a comfortable way to spend an afternoon. A mobile locksmith who comes to the lot makes more sense than getting a tow to a dealer you cannot reach without a car.
Closer to the A Line, the Station Square area and the newer townhome developments mean a lot of vehicles parked in shared garages and guest spaces. Someone commutes by train, loses a key on the platform or on the walk home, and ends up with a car in a tight garage space. We work in those settings, and we will ask about access, gate codes and parking rules when you call so that nothing delays the job on arrival.
In South Monrovia, where smaller postwar houses and apartment buildings line many streets, cars often sit on the street or in a shared lot overnight. If your keys vanish on the way home, give us the cross streets or building name. Up in the Monrovia Highlands, hillside driveways can be steep and narrow, so tell us if the vehicle is on a slope or behind a gate.
Whatever the area, ZIP 91016 covers the city, and the street address you give us is what lets us plan. If the car is on private property, such as a parking structure or a gated complex, tell us who to contact for access so we are not held up at the entrance.

Call (213) 577-1366What to check before you call about lost all car keys
A few minutes of checking can save you a service call, and we would rather you save it. Here is what is worth doing first, and what is not.
- Look in the places you have not looked: jacket linings, bag pockets, between car seats, the last restaurant or shop, the ground near the driver's door.
- Call the last place you were. Hotels, restaurants, shops and trailhead offices often hold keys at the front desk.
- Check whether a household member has a spare, including one in a drawer, a key box or another vehicle. A spare changes everything and turns this into a duplication job.
- Do not buy a key or fob online before you talk to us. A blank that does not match your vehicle, or a used fob that is already married to another car, can be money wasted.
- Do not try to force the door or the ignition. Damaged hardware adds repair work to a job that did not need it.
- If you are in a safe place, stay with the vehicle. If you are not, tell us and we will plan around that.
Frequently asked questions
Can you make a car key in Monrovia if I have lost every key?
Yes, for most vehicles. We make a new key from scratch, no original needed, and program it to the car where the vehicle requires it. A few vehicles are dealer-only, and we tell you that on the call or once we check the VIN. Call (213) 577-1366 with your make, model, year and location.
Do I need to tow my car to you or to a dealer?
Usually not. Our vans come to the vehicle, so the work happens where it is parked, whether that is a street in Old Town, a garage near Station Square or a lot at Monrovia Canyon Park. The exception is a dealer-only vehicle. In that case we say so honestly, and a tow may be the only route.
What do I need to show you before you make the key?
We need to confirm the vehicle is yours. That means your ID and proof of ownership or registration that matches the vehicle. We do this on every job. It protects you and it protects the real owner of any car we work on.
How much does it cost to replace a lost car key without the original?
It depends on the type of key, the make, model and year, whether the car is locked, how many keys you want, the time and place of the call, and whether any hardware is damaged. We do not quote numbers on a web page. We give you a quote after we know your vehicle, before work begins.
How long will the job take once you arrive?
It varies by vehicle and key type, and we do not promise a time we cannot back up. A simple key is a lighter job than a smart key, and a locked car adds a step. We tell you what to expect once we have your vehicle details, and we explain it again on site.
Will the lost key still start my car after you make a new one?
It depends on the vehicle. On many cars the newly programmed keys can be set up so the lost one no longer starts the engine. On others the options are different. We confirm what applies to your car, because it matters if the lost key could be found by a stranger.
Is a push-button-start fob different from a regular key?
Yes, it is a different kind of job, and it depends on the vehicle. We confirm by VIN and in person which type your car uses before we promise anything. Some are straightforward and some are dealer-only. We tell you which group yours falls into.
Do you work at night and on weekends in Monrovia?
Yes. Our phone line, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round. Late calls and holiday calls can affect the cost, and we say so before you agree to anything, but they do not stop us from helping.
How do I know your company is legitimate?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it, including us. We have operated since 1987 from a real storefront at 10740 Wilshire Blvd in Westwood, and you speak with our company directly, not a dispatcher who passes your job to someone else.
