The short answer is yes - a mobile auto locksmith can make a new car key with no original to copy from. It's a normal part of the job, done at the vehicle, and it's how lost-keys and all-keys-lost situations get fixed without a tow to a dealer. The one essential condition is proof you own the car. Here's how it actually works.
Why ownership proof is non-negotiable
Before any key is cut without an original, a reputable locksmith asks you to prove the car is yours - your V5C logbook and photo ID that matches it. This isn't awkwardness; it's the barrier that stops a stolen car from being keyed by whoever happens to have access to it. If a locksmith doesn't ask, that's a red flag, not a favour. We always check, and it protects genuine owners.
How the key is made from scratch
With no original to copy, the process starts from the locks themselves. The locksmith decodes the lock to find the cuts the key needs, cuts a fresh blade to match, then programmes the transponder chip to the car's immobiliser so the engine will recognise and start. If the key has remote locking, that's paired too. For an all-keys-lost job, the lost keys are erased from the car's memory so they can't start it afterwards.
It's more involved than copying an existing key - more equipment time and labour - which is why an all-keys-lost job costs more than a spare. But it's a complete, on-site fix done in one visit for most popular makes and models.
What to have ready
Your V5C logbook (or a clear photo of it on your phone), photo ID that matches it, and the car itself where it sits. Tell the locksmith the make, model, year and registration when you call, and where the car is. They'll quote based on the vehicle and head out to you.
What if the key was stolen, not lost?
Then erasing the old key matters even more. A working stolen key is a way straight back into and away with your car, so a replacement on its own leaves the risk in place. Ask for the lost keys to be erased from the car's memory as part of the job - that neutralises the stolen key for good.

Quick questions
Do I need the original key at all?
No. We can cut and code a key with no original to copy from. You'll need to prove ownership with the V5C and photo ID, and the car needs to be where we can work on it.
Can the old, lost key still start my car afterwards?
Not if we erase it. As part of the job we can remove the lost key from the car's memory so it can no longer start the engine - essential if the key was stolen.
