How do you reset an anti theft system on a Honda Passport?

To reset the anti-theft system on a Honda Passport, start by ensuring the vehicle is in the "Off" position. Then, insert the key into the ignition and turn it to the "On" position without starting the engine. Leave it in this position for about 10 minutes until the security light stops flashing, then turn the key to "Off" and try starting the engine. If the problem persists, consult the owner's manual or a qualified Honda technician for further assistance.
