That is not true.Ive heard somewhere if you change the battery on the sol remote it will need reprograming...this cant be true. is it? never heard of that.my thinken is a lock smith found a new way to make more $$ for changing batterys.
It may derive from a problem that some 2008s had in which, if you disconnected the car's battery, you would have to re-learn all of the remotes. This was due to a software bug that was fixable by downloading new software to the RCDLR (Remote Control Door Lock Receiver).
