peddler Posted July 23, 2020 Share Posted July 23, 2020 Hello.* *My Cayenne S* started messaging " key not recognized".* *It opens, starts, runs,* *but the message keeps going off evey 10 to 30 seconds while driving ( driving me nuts)* *I replaced the batteries with new Energizer batteries,* *I tried putting it in the start slot and removing the dummy key,* No phone on, nothing blocking the fob.* * *Just would like to see if there is a self reset I can do before dropping it at the dealer and waiting apx 2 weeks of more before they can get it in.* * *I have one original key fob* and one new key fod ( purchased and programmed by Porsche a few months ago )* both give the same message while driving,* * usually takes about 15 or so seconds after starting before it starts to continually go off with the warning. 2011 Porsche Cayenne S* * 157,000 KMS* * any suggestions or ideas to try would be appreciated.* * Thanks in advance.

Perci Posted July 23, 2020 Share Posted July 23, 2020 Odd thing you can try that worked for me. Get both your keys(I also had a key from my Golf) and go for a short drive. You should get a message about too many keys in the car. Next time it was started the key not recognized was gone. It was the trip to the dealer to get this checked where it cured itself.[emoji2957] It looks like the KESSY used by Porsche and VW come from the same supplier. I was not able to prove to myself that my VW key was a cause.
