The diagnostic check is to see whether the card has simply lost synch with the car, or whether it's actually fried. What they'll probably do is try to re-code the card to the car using the diagnostic computer. If that doesn't work, then they'll tell you it's new card time.
An extra 150 quid for the card is ludicrous though. That's about top-whack for the part and labour, with lots of other dealers offering the package for less. As they've already charged you an hour's labour that's probably genuinely amounted to 15 minutes, I'd expect them to supply and code a new card for the cost of the part.
If they won't, then assuming that you only have the one card, your only real commitment to this garage is that you'd need to pay for the car to be towed to the cheaper one. If you have a spare card, then use that to drive the car there yourself. If you don't, then price up having two new cards rather than one - the labour cost should be the same, so you're only paying for the part, and at least you can be sure that they'll never have you over that particular barrel again.
