I currently own an accord. Yesterday I noticed the battery light was on so I tested the battery. Battery ended up not being good along with the alternator. Swapped both out .Now when I go to start the car the car the alarm goes off for awhile .Along with that the green key light is on the dash light. From browsing forums. It seems the immobilzer is getting set off .I don't have a spare key to try. The car does not crank and the starter won't engage when I turn the key. Pretty lost at the moment .I will check the fuses on the driver side and in the fuse box later .I believe that is what I should check. Any help or guidance moving forward will be greatly appreciated.

 

Did you figure this out? If so, please say so and complete this thread. If not, have you reset your anti theft system after the battery replacement?
