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?

==============================

I've seen a similar tSB but I think it was for Odyssey. If the car is a
'99, it's not unreasonable to replace the battery anyhow. If it starts
perfectly when boosted by a non-running car, then they are probably
correct. Read through the many TSB's about immobilizer systems, some
filed under 'other' and 'Miscellaneous' here:

The battery is only a few months old.

I would really like to see this one:
TSB #05162005 -- ENGINE-CRANKS WON'T START, IMMOBILIZER LIGHT FLASHES.
*SC (NHTSA ID #10016295, MAY 16 2005)
