Hello!
I'm having an issue with one of my key fobs for my 2006 Jaguar XJ8. It burns through a brand new battery in about a day. So, if I put in a new battery, it works perfectly. By the second day, it's dead again and does not work. Replace the battery with another and the same thing happens. Fortunately, I have a second key fob and that one works great (replaced the battery at the same time). So, any ideas what could cause a key fob to burn through a battery?

 

A bad contact ie it's 'on' all the time.-a switch that does not release and is allways 'on'

 

Right. So, what do I look for? How do I figure out what on the fob is making it always "on"? Sorry for my ignorance here.

 

they’re like 10 bucks just buy 4 of them and get them all cut

 

Ah. I see them on ebay for about $15. I didn't realize this. I take it there's a way to get a new fob to "register" with my car?

get the dealer or whoever has the tools to pair the cut key to the immobilized and they can program the remote at the same time

 

Thanks! I appreciate it.
