2010 sho. So a few months ago one of my keys batteries died and I just changed it out for my spare since I didn't know at the time how to get to the battery. Just today my other one now wont unlock the car or lock it. I figured it was the battery in this one and replaced it. Same results it recognizes theirs a key and stars the car but no buttons on the key itself work. Any ideas? BTW the way the battery sits in the remote is an absolute joke..
