2001 Lexus ES300 Question: Alarm not working!

Replaced battery and now the security alarm light on dash panel will not blink and the alarm will not sound if I try to open the door w/the windows down and the doors lock w/the key button. If I push and hold the panic button alarm works fine. I think I must need to reset something but don't know what or where to look! -
Answer 1
hold lock and unlock at the same time for about 20secs -
