Common Volkswagen 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 flip key or KESSY 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 Volkswagen keys lost
More involved, but still resolvable on-site for the great majority of VWs. The locksmith reads the immobiliser through the OBD port, generates a key from the car's security data and pairs it from scratch, handling component protection on MQB-platform models. 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.
