What it means when you have lost all your car keys
Losing one key is an annoyance. Losing all of them is a different problem, because there is nothing left to copy. A locksmith cannot trace a duplicate from a key you no longer have, and on a modern car the key is more than a cut piece of metal. It usually carries a coded electronic component that the car has to recognize before the engine will run. So when people say they need a replacement car key without the original, what they are really asking for is a new key that is cut to your vehicle's lock and then introduced to its computer.
That is work we do every week, and it is very doable. It takes the right equipment, the right information about your specific vehicle, and a technician who does not guess. The sections below explain how we handle it, what changes the cost, where a dealer may genuinely be the only option, and what to expect if you are in San Marino.
If you are standing next to the car right now, you do not need to read all of this first. Call (213) 577-1366. Someone answers around the clock, every day of the year, and we can tell you what we will need before a van heads your way.
How does a replacement car key without the original work?
With no original key, we work from the vehicle itself. Here is the usual sequence. It varies by make and model, and we confirm the specifics by VIN and in person rather than assuming.
- You call (213) 577-1366 and give us the make, model, year, and where the car is parked. If you can read the VIN from the dash or your registration, that helps us a great deal.
- We ask what you have lost and what you still have: no keys at all, a remote with no blade, or a key that works the doors but will not start the car. Each case is handled a little differently.
- A mobile van comes to you. We verify that you are the owner or authorized to have the key made, which means ID and some proof the vehicle is yours.
- We determine the key cuts for your lock. Depending on the vehicle, that comes from the VIN, from the lock itself, or from decoding. Then we cut a new key.
- We program the new key to the car so the immobilizer recognizes it. Where the vehicle uses a transponder or smart key, this is the step that makes the key actually start the engine.
- We test everything before we leave: door locks, trunk if it is keyed, ignition or push-button start, and the remote functions if the key has them.
- If you want a spare, this is the best moment to make one. With the process already set up, an additional key is a far lighter-cost add-on than coming back after losing the next one.

Call (213) 577-1366What we will ask you for, and why
Any honest locksmith will ask you to prove the car is yours before making a key for it. That is not red tape for its own sake. A key that starts a car is the car. We would be handing a thief the means to drive away if we skipped this step, and we will not do that for a stranger or for you.
Plan to have a photo ID and something that ties you to the vehicle, such as a registration or title paperwork. If the paperwork is inside the car, tell us when you call and we will explain what else can work. We would rather sort it out over the phone than discover a problem when the van arrives.
- Photo ID that matches the name on the vehicle records
- Registration, title, or other proof of ownership
- The VIN, if you can read it off the dashboard or your paperwork
- Make, model, and year, plus how many keys the car originally came with
- Whether any warning lights or messages appeared before the keys went missing
What affects the cost of a lost car key replacement?
We do not publish numbers on a web page because the honest answer depends on your car. What we can do is tell you exactly what moves the cost up or down, so the quote you get over the phone makes sense.
Vehicle make, model, and year matter most. Some vehicles use a simple transponder key. Others use proximity or smart keys with more involved programming. Some manufacturers lock down the process so tightly that only a dealer can complete it. The type of key you need is the biggest single factor.
The number of keys you want also matters. Making a first key and a spare during the same visit is usually the more economical route than making them on separate days, since the setup work is shared.
Other factors include whether the car is in a place we can reach easily, whether the lock itself is damaged, and whether the car needs to be opened first. If the vehicle is locked with your keys gone, there is a lockout component, and we cover that on our car lockout page. Time of day can also play a role, since a call at 3 a.m. is not the same job logistically as a mid-morning appointment. We will tell you plainly how the quote is built before we start work, and we do not add surprises afterward.
- Key type: basic transponder, remote head key, or smart key
- Vehicle brand and whether it is open to independent programming
- How many new keys you want made
- Condition of the ignition and door locks
- Whether we have to get into the car before we can begin
- Location and the hour you are calling

Call (213) 577-1366Locksmith or dealer: an honest comparison
Many drivers assume the dealer is the only place to get a key made after losing all of them. For a lot of vehicles that is not the case, and a mobile locksmith can come to the car instead of the car being towed to a service department. That convenience is real. A towed car is an extra expense and an extra day.
But we will not tell you a locksmith can handle every vehicle. Some makes and models, especially certain newer or higher-security systems, may need dealer involvement for the key or for the programming. We do not guess at that over the phone. We confirm by VIN and in person, and if your car is a dealer-only case, we will say so rather than take your time and money for a job we cannot finish.
If you want to understand the broader range of what we do for vehicles, our automotive locksmith page covers it, and the car key replacement page is the right read if you still have a working key and just want another. This page is for the harder situation, where every key is gone.

Lost car keys in San Marino: what the city looks like from our side
San Marino, ZIP 91108, is almost entirely single-family homes on large lots, and that shapes how a lost-key call plays out. Most of the time the car is in a private driveway or behind a gate, not on a crowded apartment lot, so a mobile van can usually work right where the vehicle sits. Along the Huntington Drive corridor, where large fenced lots are common, a gated driveway means we may need you or a household member to open the gate and be present for the ownership check.
Think of a typical call: someone on one of the estate streets around Lacy Park realizes the only set of keys is gone, possibly after a day out, and the car is sitting in the driveway or out front. We come to the car, verify ownership, cut and program a new key, and test it. Nobody has to arrange a tow.
The same applies to other parts of the city. If you are in the Huntington Library area, near the Mission District's Mission Street shops, or over by the Oak Knoll border near Pasadena, we still come to the vehicle. If you lose keys while visiting somewhere in town and the car is parked away from home, tell us exactly where it is and we will plan around it.
Summers in this inland part of the San Gabriel Valley are hot and dry. That is a practical reason not to stand beside a locked car waiting longer than necessary, so call as soon as you know the keys are gone and we can talk through what to do.
If your trouble is actually at the front door of one of San Marino's older homes, with original mortise locksets, that is a different job. See our San Marino locksmith overview for what we do on the home side. For vehicles, we stay focused on getting you a working key.

Call (213) 577-1366Before you call, and what to do afterward
A few quick checks can save you a service call. Look through coat pockets, bags, and the places you were last. Check whether a household member or a valet has a set. If the key has a tracking tag, use it. If you genuinely cannot find anything, call us.
If the car is locked and you are outside it, we may need to open it before work begins. If a key broke off in the ignition or a door, that is a separate problem, and we handle it through broken key extraction. If the ignition itself is worn or failing and that is why the key is not working, see ignition repair. Do not force anything. Forcing a lock or ignition turns a key problem into a repair bill.
Once you have your new key, think about what the new setup means. If the old keys could be found by someone else, ask us whether the car's system can be set so the lost keys no longer start it. Whether that is possible depends on the vehicle, and we will tell you straight. Then make a spare and keep it somewhere that is not the car or your usual bag.
- Retrace your steps and check pockets, bags, and the places you were last.
- Ask anyone with access to the car whether they have a set.
- Gather your ID, registration or title, and the VIN if you can.
- Call (213) 577-1366 and tell us the make, model, year, and where the car is.
- Ask us whether the lost keys can be disabled on your particular vehicle.
- Have a spare made during the same visit, then store it away from the car.
Related help when the key is only part of the problem
Lost keys often come with other issues. If you need a remote or fob for a car that already has working door keys, our key fob replacement service is the closer match. If a key is cut but the car will not start, transponder key programming explains how that second step works. For after-hours situations in general, our 24-hour locksmith page describes how we handle calls at any time of day.
If you are not sure which of these describes your situation, just call. Describing it to us out loud is usually faster than reading three pages, and we will tell you which service fits. You can also use our contact page if you would rather write than talk, though a call is quicker when you are locked out of your own transport.
Frequently asked questions
Can you make a car key if I have lost all of my keys?
Yes, for many vehicles. We work from the VIN, the lock, and the car's own system rather than from an original key. Some makes and models may need dealer involvement, and we confirm that by VIN and in person instead of promising over the phone.
Do I need the original key to get a replacement car key?
No. A replacement car key without the original is exactly what this service is for. We cut a new key to your vehicle and program it so the car recognizes it. If you still have one working key, a simple copy is usually the more economical route, and our car key replacement page covers that.
What do I need to show you before you make a new key?
Photo ID and proof the vehicle is yours, such as registration or title. We also ask for the VIN, which you can usually read off the dashboard or paperwork. We will not make a key for a car without verifying ownership.
Will you come to me in San Marino, or do I have to tow the car?
We come to you. Our mobile vans serve San Marino, and in most cases the work happens right where the car is parked, whether that is a driveway, a street, or a gated lot. Our mobile locksmith page explains how that works.
How much will a lost car key replacement cost?
It depends on the vehicle, the type of key it uses, how many keys you want, the condition of the locks, whether we need to open the car first, and the time you call. We explain how your quote is built before we begin, and we do not add charges afterward.
Is it better to go to the dealer or call a locksmith?
For many vehicles a locksmith is more convenient because we come to the car and avoid a tow. Some vehicles, though, are dealer-only for keys or programming. We check by VIN and tell you honestly if yours is one of them.
Can the lost keys be stopped from starting my car?
On some vehicles, yes. When we program a new key, it may be possible to remove the old ones from the car's memory. It depends on the make, model, and year, so ask us when you call and we will confirm for your specific car.
Are you available at night or on weekends?
Yes. Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. If you are stranded late at night, call and we will tell you what we need to get a van to you. See our emergency locksmith page for more on after-hours calls.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they work on your car. Also be wary of anyone who will not explain what drives the price or who refuses to verify ownership.
