We have Keyless Go and one Keyless Go key. The other key is a regular Keyless Entry Key but does not operate the keyless go function. In any case...I recently replaced both key batteries and now find that the range on both keys has deteriorated. The batteries are Duracell. I guess I got some bad batteries...they sure did go to hell fast. Any one else have this problem?

 

New Battery cured the problem.
