Help with keyless remote programming
 

My keyless entry remote broke on me and I had to buy a new one off of Ebay. However, the programming instructions don't seem to be working.
It's for a 1998 Civc EX 2 door. The little Valet button on the radio doesn't do anything when I hold it down. Can anyone help me? It just so happened that I left my lights on and had to recharge my battery, does this effect anything? What am I doing wrong?
