My 99 Accord 4cyl is not starting because immobilizer refuses to
accept both keys. The car was towed to Honda service, who are saying
that this is due to a bad battery, test says that it cranks at 420
amps cold, should be 640.
Service guy told me that there is a TSB for this: bad battery can
cause starter to crank ok, but messes up immobilizer. Anyone heard of
this?
