has anyone ever had their car not recognize the chip in a key? Does it ever become un programmed thru normal use?? I always carry a spare working and programmed flip key in the trunk, but if the chips never loose the connectivity, I would rather store the flip key at home instead... Brandon

 

Can I believe that with no replys that there is never a loss of connectivity between key chip and receptor?? Brandon

 

Seems to reasonable to think the answer is that no-one has had it happen.

 

Sorry, I've not heard it happening under normal circumstances. Maybe if near a supermagnet or particle collider?
