A problem I have with my odyssey is that the key 
contacts aren't up to handling the current when 
2 keys are pressed.  With 1 key, you are just 
picking off a voltage and contact resistance isn't 
as critical.  With 2 keys, there is some current 
flow and it's much more susceptible to flakey 
contacts.  At least that's been my theory.
