That's a great relief, and I did the reprogramming now both keys are working. I just scratch my head why my current key stopped working just after 3 days of not driving. It can only be a) a sudden battery death but now it is recharged. b) somehow this key lost sync.

The only other explanation would be this key has gone through airport x-ray. Could the x-ray wipe out the chip memory? That reason is very remote.
