well the dealers cocked mine up, but they sorted it out, and a mobile bloke might not be so commited'
first they realised i needed to get 2 new keys as they needed 3 to code the system and i only had one, i argueued so they met the cost of the second key
then they cut the new keys wrong, the worked the ignition but not the doors
then they forgot to put my old key back on the system and one of the new keys stil didnt work so i was back to one
then thay re did the lot so i edned up with 3 new keys for £127 and a few arguments all in including vat etc. I was fairly pleased with that, but it is a fairly valuable vehicle and i suppose that has to weighed against the cost of the key.
