Ever walked up to your car and touching the drivers door handle doesn't unlock the car? Or get into the car and you get the Key not found message on the display? Well I found the simple reason that is happening occasionally to some of us. I was putting my keys in the same jacket pocket as my cell phone. Because of the close proximity it seems that the idle signal from the cell phone was blocking the radio signal from the Key Fob. If the phone and key fob are in different jacket pockets or one of the two is in my hand I've seen zero issues. Hope this solves that nagging feeling that your Key Fob battery is dying or there is a problem with Key Fob itself.
THANKS! Just recently had those messages pop up on me. I'm also having some issues with the Bluetooth connecting automatically. Weird. iPhone ?
