What actually happens
When every key is gone, it is called an all-keys-lost job. It is more involved than cutting a spare because there is no working key to copy from. We start the immobiliser side from scratch and program a fresh key to your car.
That is normal work for a wide range of vehicles. What changes it is the make, model and year, which is exactly why we ask for those first. Some of the newest high-security platforms can be dealer-only, and if yours is one we will say so plainly instead of stringing you along.
