Double check that battery.

Check the battery connections to see if they are clean and secure. Check the battery voltage is 12.6 volts if you don't have a volt meter turn on the head lights are they bright? Try turning the ignition switch with the lights on do you hear a click or do the lights dim? That would show the ignition switch is trying to supply power to the starter. It is obviously something electrical perhaps the starter has failed, neutral safety switch, ignition switch, too many things it could be.

use your spare key . some times the key goes bad . If that does not work ,then the signal from the starter to the engine could be failing they will change out the box. YOu give them your lisence and they send in to BMW for the part ( I changed out the box because i was afraid that i would get stuck some where , in fact it was just my key going bad as I had the problem again , this time I used my spare key to start it and it started right up . )

2002 BMW 330i when to it yesterday and nothing would not turn over pushed it because it is standard and nothing would not turn over. took battery cables off reset the computor by waiting 15 min. before putting cable back on waiting 19 min. before turning key on but still no fire. Checked everything do not have spare key. Do you think it is the key and do you have to pay 200 to 300 for a key from the dealer. Where is the box you talked about going to the starter?

Had this exact problem. Replaced the battery and still the lights would come on but car would not turn over. Then read the answer here from doral and yep.... the spare key started it right up. I'd try this first. Bet my original battery was fine.
