My electronic key will not unlock any of my doors by pushing the little button in the door handles. My electronic key will allow locking of the doors by pushing the little button and pushing the lock or unlock on the key works. My wife's key works OK for everything. I changed the battery in my key twice, the second time I used a higher voltage lithium battery, with no change. This happened after the first time they tried to install the H264 software update. When they finally got the update installed a week later, it did not correct itself. The dealer couldn't figure out what was wrong and said they ordered me another key. That was a month ago. No answer as to when the new key is coming. Anyone else have this problem?
