They're still working on this. Key Cards are issued by B&H Buses, Metrobus Buses and Southern Rail - but they are not interchangeable even among these three companies (even though they are all part of the Go Ahead Group). I believe the first steps towards interavailability will happen later this year.
Why so slow? God knows. I was a member of a regional working group back in the 1990s that was trying to ensure that a single smartcard might be developed to cover all bus, tube and rail services throughout the South East (including London) - but nothing much came of this, largely because of squabbles about detail, that focused on technical issues, rather than customer convenience. Eventually, London Buses and London Underground got fed up with the lack of progress and went their own way with Oyster. That now leaves everyone with the problem of integrating Oyster with The Key.
Getting other smartcard systems (like Albion season tickets, Nectar Cards and Costa Coffee Cards) all working the same way is a dream - but I'm not holding my breath. I guess someone might invent a universal system sooner or later. I've got a great idea for the brand name. It could be called "Cash".
TfL (Transport For London) also have "wave and pay" , contactless payments with a debit or credit card using the same smart reader which you "tap in" with an Oyster card.
