Green Key Sign on 2011 Honda Accord Dashboard on New Key and Not starting?

I make a spare key from Honda dealer and programmed myself. The central locking system working fine with new key, but the engine ignition not working green key sign is visible on dashboard. I know that ignition program is not sync with new key. My question is, can i fix it with out taking the car and key to dealer just like programmed the central locking system?

Short answer: NO! That Green light with the key symbol stand for the Immobilizer system as it's not recognising the new key and only the dealer or a locksmith with a scanner capable to do the reprogramming the system. What you did is just for the key fob itself. HTH
