Does a 2000 Honda CR-V have a car alarm?
My 2000 CRV EX has an alarm/immobilizer factory installed. I
would assume that the SE and LX would at least have it as an
option. If you have a keyless entry (Remote), try this to
confirm... Roll down your window and with the keyless entry lock
the vehicle (pressing lock twice on the remote should sound the
horn for alarm-on). Now reach in and unlock the door through the
open window and open the vehicle...does the alarm sound?? If not,
try turning the key, it may still be immobilized until you click
you remote to unlock and won't start.
