S40: Remote Key Fob Reprogramming

[JamesM81]

I recently bought a March 2001 S40 T4 that didn't come with any remote key fobs. I just assumed that it would have these and didn't realise until I had paid for the car. I was hoping to buy a couple of used fobs and get these reprogrammed but have been told by several auto locksmiths that only Volvo dealers can do this and was then told by a Volvo dealer that they can't guarantee that reprogramming used ones will work and that the best thing to do is to get new ones from them and for them to program them which will work out at around £208 plus VAT for the pair. Is this right? Or should I be able to buy used ones and take them to a Volvo dealer and get them reprogrammed for my car? Any thoughts would be much appreciated!
