It possible that you need your ECM reflashed. Ehen you change your battery or it dies, so does some of the stored information...

a problem like this happened before, turned out to be a bad battery in the key FOB, and it just needed to be reprogrammed. Which was able to be done by taking the negative terminal off the battery for 1 minute. Once the battery was hooked back up, the Jeep started right up.
