why does the battery in my key fob need changing every day

What is your question?

I have the Izuzu rodeo Denver 2007 model and have a problem with the key fob. Sets alarm off and wont drive unless the fob battery is changed daily and lights in fob work. Can you help, I'm using spare key at the moment but am worried that the fob will go the same way.

What makes this problem better or worse?

Putting a brand new battery in every day

How long has your 2004 Isuzu Rodeo had this problem?

Few weeks
