More detail on your problem might bring more help.

You didn't say what year it is but these are the codes for OBDII ('96 and newer)
B2710 - PASSKey Open/Shorted Pellet
B2780 - Wrong Resistor Before Good
Sounds like you may need a new key. See if your spare works.

Clear the codes and see if they return. Might just have been a computer fart.

It sounds like you (or someone else) tried to start it with the wrong key, then used the correct key and it started.

Clear the codes.
