I have Keyless Entry and when I get in to drive and my wife gets in the passenger seat, we both have our individual key fobs in our pockets. The dash warning light shows a yellow key symbol and the message says, "Multiple Keys detected." There is a constant low level warning tone emitted while the condition exists.

Is there a way to by-pass this warning and stop the tone sound? Many times we will drive somewhere, I'll get out and she continues to her destination so we both need our key fobs with us. Or if we drive somewhere, park and then she comes back to the car on her own, she would not be able to get into the car without her fob.

 

The problem lies in the system's uncertainty about whose choices to apply from the memory settings. I can think of ways to get around that as a design engineer but none of them were used.

As an owner, the only solution I know is to leave one key behind. The individual settings can be applied by pressing button one or two on the door.

The drawback of course is that it is very easy to walk away with the key in one's pocket, leaving the engine running and the car apparently ready for use. In fact, the security system lies waiting to confound anyone (like one's spouse or the hotel valet) who tries to drive away in one direction while you walk in the other.

To deal with that complication, it should be your key left at home if you're getting out first. That way, your wife won't get a mile away and sit cursing your soul while the security system wails and the engine sits idle because you forgot to give her the key.

Gary, which the valets didn't seem to mind but they run between cars all the time and the extra twenty-dollar tip was consoling

 

Have your wife wrap her key in aluminum foil then remove the foil when she will use the key to continue driving. The aluminum foil is an effective shield between the key and the vehicle.

 

Very good! Better yet, my wife always carried her key in an inner pocket of her handbags. She could slip foil into one such pocket so that the key is shielded when carried there. But when she's alone, the key can remain in her purse in the general compartment or a different, un-shielded, pocket where it will work the way it's supposed to. That is, by making it quick and safe to get into the car in a parking structure without fumbling to find the key.

You guys give your wife a key?

 

You can disable the tone thru the settings menu. My wife has her key in her purse all the time and I take mine also and see the same warning. Pull the little stick toward you and the big warning changes into the smaller one in the lower portion of the display.

Good idea with the aluminum foil wrap for the key. That's what I was thinking too as that method works well with the electronic bridge toll transmitter.

The Multiple key warning screen changes to the small key symbol icon with a pull of the right side stalk, but the ever-so-low frequency sound of the reminder chime is still present. You have to turn down the radio to hear it or compare it while driving with only one key.

Since it is my wife's car, I am lucky she gives me a key

Can't one person get in the car start then have the second person get in with their key? That way the car senses one key and memory settings are set. Then when the second person gets in with their key the car is no longer searching.
Any way you do this its a pain, seems like a strange design miss for Porsche.
