I believe its the same thing as mine. I just took it to honda house and re-registered the key and the car is working fine. They charged me $100 though for so called labor charge, but they didn't do anything except for resetting the key.

@ bhojpure: If the key light blinks on the dash board whenever you insert your key, the most probably you are experiencing the same problem i did. There is no other option except taking it to dealer.
