A lost or broken Kia key in London rarely needs a tow to the main dealer. A mobile auto locksmith with Kia diagnostic equipment can cut and programme a fresh key - transponder or proximity smart key - for the Picanto, Rio, Ceed, Sportage, Niro and the rest of the range on-site, usually in 30-60 minutes and typically 30-50% less than the dealer route.

Common Kia key problems we solve
Spare key needed (you still have one working key)
The quickest and cheapest job. With one working key present, a fresh transponder or smart key is cut and programmed in 20-40 minutes. Keep the spare separate from the original to avoid the far pricier all-keys-lost call later.
Lost or stolen key (one key still works)
A new key is cut and programmed, and the missing key is wiped from the immobiliser so it can no longer start the car. Most insurers expect this after a key theft.
All Kia keys lost
More involved, but still resolvable on-site for almost every Kia. The locksmith reads the immobiliser through the OBD port, generates a key from the car's security data and pairs it from scratch. See the full all-keys-lost guide for the sequence.
Smart key fault, broken case or flat battery
Often the cheapest fix - a flat coin cell, a cracked case or a worn button pad is usually sorted in 10-15 minutes without reprogramming. See car key fob repair.

Do you programme Kia smart keys?

Is a mobile locksmith cheaper than a Kia dealer?
Usually 30-50% cheaper for the same key. The dealer route needs the car recovered to site, adds days waiting for the key to be ordered, and charges dealer labour on top.
