My old man disconnected the battery on my sister's 1996 Accord EX today for some odd reason. My question is when he reconnected the battery the radio said "CODE". Punched in the code and everything nothing happened. So went to the owners manual and read it and said leave it on for an hour if you mess up after 3 tries. Left the system on for an hour and re-punched in the numbers and nothing happened. Are you suppose to hold the numbers down for a few seconds till a beep or something?! Any help will be appreciated !!! THANKS!
