I replaced the battery in the key fob and now it won't work, does it need to be reprogrammed?

Hi,

Replacing it shouldn't require reprogramming. Are you sure you have the battery positive facing the right direction in the FOB?

As far as programming, here is a link that explains how to do it:

Let me know if that helps.

Take care,
