What do you do when you've lost all your car keys in Valencia?
Losing one key is an annoyance. Losing every key is a different problem, because there is nothing left to copy. A spare can be duplicated on a machine in moments, but with no key at all, a new one has to be built from the information in the car itself. That is lost car key replacement, and making a replacement car key without the original is work we do regularly out of our mobile vans.
Valencia is a master-planned community of named villages tied together by paseo walkways, and it spreads out enough that a stranded driver can be a long way from anyone who can help. You might be at the curb outside your own house in one of the tract neighborhoods, in a lot near Henry Mayo Newhall Hospital, or at work in the Valencia Industrial Center. The situation is the same everywhere: the car is fine, you are not going anywhere, and you need a working key.
Before you call, do a short, honest search. Check coat pockets, bags, the last place you set things down, and anyone else who drives the car. If you can see the keys sitting inside a locked car, that is a lockout rather than a lost-key job, and our car lockout service is usually the simpler fix. If the keys are truly gone, dropped somewhere you cannot retrace or taken along with a bag that had your address in it, tell us that on the call. We can talk through what makes sense for the car and for your security.
How is a replacement car key made without the original?
People often assume a locksmith needs the old key to make a new one. We do not. A modern car key has two parts to it: the physical cut, if the key has a blade, and the electronic side, where the car decides whether it recognizes the key at all. Both can be created without an original in hand, but the method depends on the vehicle. This is how a typical job goes.
- You call (213) 577-1366 and tell us the year, make and model, where the car is parked, and whether it uses a blade-style key, a remote-head key, or a push-button start with a smart key.
- We confirm you are the owner or authorized driver. This is a firm step on every lost-key job, and it protects you as much as anyone.
- We identify the key your car uses by VIN and by looking at the car in person. We do not guess from the model name alone.
- If the key has a blade, we cut it without an original, using the lock itself or the vehicle's key information, depending on the car.
- We program the new key so the car's computer accepts it. On many vehicles this is where the real skill is, and it is covered in more detail under our transponder key programming service.
- We test everything before you pay attention to anything else: turn the ignition or start the car, lock and unlock the doors, and check any remote buttons the key is supposed to have.

Call (213) 577-1366What do we need from you for a lost-key job?
Making a key for a car nobody can show a key for is exactly what a thief would ask a locksmith to do, so we ask for proof every time. It is quick if you have the right things on hand, and it is not negotiable even for regular customers.
- A photo ID, with a name that matches the vehicle's registration or title.
- Proof the car is yours or that you are authorized to have a key made for it, usually the registration, title, or a rental or lease document.
- Access to the VIN, which is usually visible through the windshield at the base of the dashboard or on the door jamb sticker.
- The car in a place where we can reach it. If it sits behind a community gate, give us the gate code or tell us who can let the van in.
- Any remaining pieces, even a dead remote or a cracked key shell. They sometimes make programming simpler, though we do not need them.
Will a locksmith be enough, or does your car need a dealer?
For a large share of vehicles, a mobile locksmith can cut and program a replacement key on the spot. But not every car allows it, and we would rather say so than waste your time. Some makes, model years, and key systems restrict programming to the dealer, require a security code only the manufacturer releases, or need a key blank that has to be ordered. We do not put chip or key-type details for particular models on this page, because they change by year and trim and a wrong detail helps no one. Instead, we confirm by VIN and in person.
If your car turns out to be a dealer-only case, we will tell you plainly, before any work begins. You will not pay us to find out something we could have told you on the phone. If it is a car we can do, we will say that too, and explain what the job involves.
If your key is a push-button, proximity-style smart key, the work and the equipment are different from a basic blade key, so ask about that when you call. Our page on key fob replacement covers what changes with remotes and smart keys, and our general car key replacement page covers the broader job when you still have a key to work from.
How much does lost car key replacement cost in Valencia?
We do not publish numbers on a page, because the honest answer is that two lost-key jobs can look alike and cost very different amounts. What we can do is tell you what moves the price, so the quote you get makes sense when you hear it.
Once we have your VIN and know what the car needs, we give you a quote before we start the work.
- Type of key. A plain metal-blade key, a transponder key, a remote-head key, and a proximity smart key are four very different products with different costs behind them.
- Make, model, and year. Some vehicles have simple security systems and others have strict, more involved ones.
- How the key is cut. A standard edge-cut blade is simpler than a high-security milled or laser-cut blade.
- Whether the car has to be programmed from scratch. Losing every key can mean the car's system has to be set up to accept a new one, which takes more equipment than adding a key when one already works.
- How many keys you want. Making a second key during the same visit is usually more efficient than coming back later.
- Condition of the ignition and locks. If the ignition cylinder is worn or damaged, that is a separate repair, and we will tell you so up front rather than adding it quietly.
- Distance and time of day. Our storefront is in Westwood and Valencia is about 34 miles from our base. Nights, weekends, and distance all play a part in how a mobile job is quoted.

Call (213) 577-1366Is a locksmith or a dealership the better choice for a lost key?
There is no single answer, and anyone who tells you there is one is selling something. A dealership can handle almost any vehicle it sells, but for an all-keys-lost situation you generally have to get the car to them, which can mean towing a vehicle that runs perfectly well, and you work to their schedule and parts availability.
A mobile locksmith comes to the car. You stay where you are, the key is made at the curb, and if the car is something we can do, it is usually the more economical route because it avoids a tow and a second trip. That is not a promise on any individual job. The exceptions are the dealer-only vehicles described above, where the dealership really is the only option, and we will tell you if yours is one of them.
If you are not sure which way to go, call us with the VIN and we will tell you what we can and cannot do before you commit to anything. Our automotive locksmith page lists the other vehicle work we handle.
Lost car key replacement around Valencia: neighborhoods, ZIP codes, and where people get stuck
We cover both Valencia ZIP codes, 91354 and 91355, across the villages: Bridgeport, Northpark, Northbridge, Valencia Summit, Valencia Glen, Old Orchard, Valencia Hills, Westridge, the Copper Hill area, the northern edge of Tesoro del Valle, and the newer FivePoint Valencia development to the west. A car with no key looks the same in every one of them, but the details around the car are not.
Much of Valencia is HOA-governed tract housing, with some gated enclaves in places like Westridge and Tesoro del Valle. If your car is parked behind a community gate when the key goes missing, give us the access details when you call. A van that cannot get through a gate cannot cut a key, and a quick message to your HOA or a neighbor with the code saves everybody time.
Closer to Town Center, apartment and condo clusters along the McBean Parkway corridor create a different version of the same problem. Residents there often share parking areas and visitors come and go, so a missing key can mean wondering whether it was left somewhere or picked up by someone else. If your keys disappeared and your address or garage access was on the same ring, tell us. We can talk through whether it makes sense to also change your door locks, which our apartment lockout and lock rekey pages touch on. Student housing near CalArts is another common setting, where a student who has lost the only key to a car may need to prove ownership with paperwork that is sitting with family elsewhere. Have what you can ready, and call anyway so we can tell you what is workable.
Valencia's hot, dry summers add a practical edge. Sitting in a parked car with no key and no air conditioning wears on you quickly, so if there are children or pets with you, say so at the start of the call. Tell us exactly where the car is, the nearest cross street or business, and which village, and we will tell you how we plan to get to you.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987. We run a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans that reach 140 cities across Los Angeles and Ventura counties, Valencia included. When you call (213) 577-1366 you reach us, not a call center that sells the job to whichever subcontractor picks it up. One company handles the phone, the work, and anything that goes wrong afterward. The line is answered 24 hours a day, 7 days a week, all year.
David, the owner and lead technician, oversees how we do this work. Lost-key jobs are where shortcuts hurt people most, so the ownership check, the VIN confirmation, and the honest word on dealer-only vehicles are part of how we operate, not extras.
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 you are thinking of hiring for their license number, including us. A company that will not give it to you is telling you something. If you need a locksmith urgently at an odd hour, our mobile locksmith page explains how we work on the road.
What should you do after you have new keys?
Do not stop at one key. The real cost of an all-keys-lost job is the setup of the car's system, and making a spare while we are already there is usually much easier than having to start from nothing again. Ask about a second key before we pack up. If you get a spare later from an existing key, our key duplication page covers that.
If an old key turns up after we have made a new one, ask us whether the lost key can be removed from the car's memory so it no longer starts the car. Whether that is possible depends on the vehicle, and we will tell you what applies to yours.
If the ignition feels rough, sticks, or is hard to turn with the new key, mention it during the visit. A worn ignition can make a good key seem faulty, and we cover that kind of repair under ignition repair. Keep a spare somewhere safe that is not on you or in the car.
Frequently asked questions
Can you really make a car key if I have lost every key?
Yes, in most cases. A replacement car key without the original can be cut and programmed from the vehicle's VIN and the car itself. Some vehicles are dealer-only, and we confirm that by VIN and in person before starting, then tell you plainly if yours is one of them.
Do I need the original key or a spare to get a new one made?
No. Lost all car keys is exactly the job this service covers. If you have any remaining piece, such as a dead remote or a key shell, bring it, since it sometimes helps, but it is not required.
What proof of ownership do I need?
A photo ID with a name that matches the registration or title, plus the registration, title, or lease or rental paperwork for the vehicle. We ask for this on every lost-key job to protect owners from someone else getting a key to their car.
Will you come to my car in Valencia, or do I have to bring it to you?
We come to you. Our mobile vans serve Valencia, in ZIP codes 91354 and 91355, and the keys are made where the car is parked. If it is behind a community gate, have the code or a contact ready.
Can you tell me the price over the phone?
We can explain what drives it, and once we have your VIN and know the key type, we give you a quote before work begins. Key type, make, model, year, how many keys, ignition condition, and distance and time of day all affect the cost.
Is it better to call a locksmith or the dealership?
For many vehicles a mobile locksmith is the more convenient and often more economical route, because it avoids towing. For dealer-only vehicles, the dealership is the only option. Call with your VIN and we will tell you honestly which situation you are in.
Will my old lost key still start the car after you make a new one?
It depends on the vehicle. On some cars the lost key can be removed from the car's memory, and on others it cannot. Ask us when we confirm your VIN and we will tell you what applies to your car.
Can you replace a push-button start smart key?
Often yes, but smart keys are a different job from a basic blade key and some vehicles restrict them to the dealer. We confirm by VIN and in person, and our key fob replacement page explains more about how remotes and smart keys differ.
Should I make a spare while you are already there?
Yes, it is worth asking. The hardest part of an all-keys-lost job is setting up the car's system, so adding a spare during the same visit is usually simpler than starting over later.
