My 2013 Porsche Cayenne Keyless Push Start doesn't work all the time.
25% of the time the car will not start and gives the message "Key Not Recognized". This happens if I am holding the key in my hand, or in my pocket, or in the center console. Car is back at the dealer for the 3rd time for this problem. They already replaced the key batteries and the keys; but it has not helped. Anyone else had this issue?

Thanks

 

I have it all of the time except when I turn off the Bluetooth on the Iphone. Once it is off, the car sees the key right away and starts. BTW, when I bought the car it came with five keys. All work and all have the problem with the Iphone...

 

Great tip on the iPhone & Bluetooth..................I will try it.

Thanks Much
