if it opens it with the beeper but it does not start...new key
if it opend with the key but no start ...new key
or not open with beeper but the car runs new bat.

Everything works but the remote function. I haven't considered the battery in my original post since I've always dealt with old style keys and I thought the new style key had the battery that lasted forever.
I'll try the new battery and report back.
