When you realize you’ve lost both car keys, what to do is usually not obvious – and that is exactly why people lose time, money, and patience in the first hour. If your car will not unlock or start and you have no spare, the quickest way forward is to stop searching in circles, confirm the car is secure, and get a mobile auto locksmith involved before the situation gets more expensive.
Lost both car keys what to do first
The first step is simple: pause and narrow the problem down. Did you genuinely lose both keys, were they stolen, or is one broken and the other missing? That detail matters because the solution is not always the same. If there is any chance the keys were stolen with documents or anything showing your address, treat it as a security issue, not just a replacement job.
Next, check the last practical locations properly once, not ten times. Look where the car was last used, check coat pockets, bags, work surfaces, the ground around the parking space, and any place a child may have moved them. If someone else drives the car, ask them directly before you assume the worst. A focused ten-minute check makes sense. A random two-hour search usually does not.
After that, gather the basics you will be asked for. Have your registration, make and model, location, and some form of ID ready. If the vehicle is parked somewhere awkward, such as blocking a driveway, in a pay-and-display car park, or at the roadside, mention that straight away. The faster you give clear information, the faster the right help can be dispatched.
Why replacing all lost car keys is different
Losing one key is inconvenient. Losing both is a different job entirely. Most modern vehicles do not just need a piece of metal cut to fit the lock. They often need a transponder chip programmed to the immobilizer, remote buttons synced, and in some cases old keys deleted from the system so the missing keys can no longer start the vehicle.
That is why a basic key cutting shop often cannot help, and it is also why a dealership is not always the fastest route. Many drivers assume the car has to be towed away. In a lot of cases, it does not. A mobile auto locksmith can usually come to the vehicle, gain access if needed, cut a new key, program it on-site, and get you moving again without dragging the car to a workshop.
There are trade-offs, though. Some high-security systems, newer smart key setups, and certain imported models can be more involved. The exact method depends on the make, model, and year of the vehicle. But for a large number of everyday cars and vans on the road, same-day mobile replacement is the most practical option.
Your options after losing both keys
You generally have three choices: keep searching and hope they turn up, contact a main dealer, or call a specialist auto locksmith. If the keys may genuinely be nearby and you are in a safe place with no time pressure, another brief check is reasonable. If you need the vehicle today, that route rarely helps for long.
A main dealer may be able to supply a new key, but it often means delays, paperwork, and towing if the car cannot be driven. For many people, that is where costs start climbing. You pay for transport, wait for the key order, then book programming.
A mobile auto locksmith is usually the faster choice when the car is stranded and you need a practical answer now. The job can often be completed at your home, workplace, roadside location, or car park. That saves time and avoids the hassle of moving an immobile vehicle.
What a mobile locksmith will need from you
Most of the delay in lost key jobs comes from missing details, not the work itself. Be ready to confirm the vehicle registration, exact location, make, model, and year if you know it. Mention whether the car is unlocked, locked, or in a secure garage. Also say if you suspect theft rather than simple loss.
You will also need to prove the vehicle is yours or that you are authorized to use it. That is standard and it protects everyone. A professional locksmith should be careful about this, especially in all keys lost situations.
If the keys were stolen, ask whether the missing keys can be removed from the system. This is one of the most important parts of the job and many drivers do not think to ask. A replacement key gets you moving. Deleting lost or stolen keys helps protect the vehicle afterward.
How long does it take?
That depends on the vehicle and the system it uses. Some jobs are straightforward and can be completed quickly once the locksmith is on site. Others take longer because access has to be gained first, key data has to be generated, or programming is more complex.
The good news is that mobile service is usually still far quicker than arranging a tow and waiting on dealer lead times. For local drivers who rely on the car for work, school runs, appointments, or deliveries, speed matters just as much as price. Being back on the road the same day is often the difference between a bad morning and a completely lost week.
How much does it cost when all keys are lost?
All keys lost work costs more than duplicating a spare, because it is a bigger job. You are paying for specialist tools, vehicle access, key cutting, programming, and often emergency call-out availability. But that does not mean the dealership is your only serious option.
In many cases, a mobile locksmith works out more realistically priced because there is no towing and the work is done where the car sits. The final cost depends on the type of key, whether it is remote or non-remote, whether the vehicle uses a smart proximity system, and whether extra security work is needed.
If you are comparing quotes, make sure you are comparing the same job. Ask whether the price includes access to the vehicle, cutting, programming, remote functions, and deletion of old keys if needed. A cheap starting figure is not helpful if half the job is added later.
If your keys were stolen, not lost
This is the point where urgency really matters. If there is any chance someone can connect the keys to your vehicle, your priority is not just getting a new key made. It is making sure the old keys no longer work.
That may involve reprogramming the vehicle so the missing keys are removed from memory. In some cases, lock changes may also be worth discussing, especially if the theft involved house keys, address details, or repeated suspicious activity. It depends on the risk. Not every situation needs the same level of response, but ignoring the security side is a mistake.
How to avoid this happening again
Once you are back in the car, do yourself a favor and get a spare made. This is the single cheapest way to avoid another all keys lost situation. People tend to delay it because the emergency is over, but that delay is exactly how they end up stranded again.
Keep the spare somewhere separate from your everyday key. Not in the same bag, not on the same bunch, and not inside the vehicle. If you use one car key for work, school, home, and shopping, you are carrying a lot of risk in one place.
It also helps to replace damaged or worn keys early. A cracked remote, weak casing, bent blade, or key that only works intermittently is a warning sign. Problems usually get worse at the most inconvenient time.
When fast local help makes the difference
If you are stuck in the West Midlands, Warwickshire, Leicestershire, or nearby areas, this is exactly the kind of job a mobile specialist is built for. Car Key Maker handles all keys lost situations on-site, with practical help aimed at getting drivers back into their vehicles and back on the road without the added hassle of towing and workshop delays.
When both keys are gone, the best next move is not guessing, waiting, or paying for the wrong service first. It is getting the right specialist involved quickly, with the right information, so the problem can be fixed where the car is parked and your day can start moving again.
