Ok. Try to remove the battery posts and touch them together for about 30 seconds and then reinstall them. Make sure the key is not in the ignition when you do this. Let me know if this works. And also try two different keys if you have two. And also why did you change the battery ?

Ok. Try my battery trick and let me know if this helps.
This is very common but the results are always varying and I still have not found a common denominator to this issue but a lot of people have this issue right after a battery replacement.
