Been having grief getting a transponder programmed in a new key for my golf, all i get is "you have to send off the germany, £180 please!!"

Its a flip key type and i have all the bits, the blank blade and remote, all i need is for a tech to spend two minutes reading the ECU security code, generate the 4 digit code from this and program the transponder. I can get the blade cut no bother! Is this possible or am i going to have to fork out and take it in the holiest of holes again from VW UK.
