most of the new cars come with coded keys...

im just curious how they lose their codes n what not... is there a way to prevent this?

 

the most common is when replacing the ecu without using a factory honda
diagnostic tool (a fancy tablet computer) to transfer all the key codes.

in your case, your car cranks but won't start. have you tried using a different
ignition key. if you've checked all the basics fuel and spark. then you'll
probably have a faulty immobilizer control unit-receiver, this resides in the
ignition switch.

note: when you try to start your car does the "key symbol" in your instrment cluster flashes. if yes, it usually indicate a faulty key or faulty immob. unit.
