Just had a new battery installed on my 98 Vectra, when i came to putting the codes into the radio for some reason it won't accept the code. I have a Vauxhall Car Pass and on the reverse it gives me a list beginning with the VIN number and then a security code, then further down the list it says Radio Type/Code and a four digit number. I have tried inputting both these numbers (security number and radio type/code) but for some reason the radio won't take either number, now i only have 5 more attempts before i get locked out. Have I been using the wrong numbers? These are the only numbers that i can find, anyone know what I'm doing wrong?
