Central lock - key signal problem

[Lukas Grom]

Hello

I have a problem with my Cayenne S '05. I think there is something with the antenna signal. When I try to open the door with the key, I can do it with about 1-3m. When I drive the car a few minutes and finish, I try to close the door with the key, but the door does not close. I click the button several times, the green lamp on the key lights up and after several attempts the door closes. Sometimes I have to put the key a few millimeters from the door and sometimes help. When after that I wait a moment and tries to open the door is the same problem. It is the same with the window tailgate opening button.

The car battery was being charged, the key battery was being replaced. I don't know what the problem may be.

I will add that the opening button (the one with the wiper) does not work for the tailgate.

Does your Cayenne have one battery or two?

Hello

I have one battery. I only have a Bose subwoofer and a spare wheel in the trunk.

Do you have a second key to try?

Unfortunatelly, not. I got one key when buying.

Does your car have the Kessy system, "Porsche Entry & Drive"?

If so, you will likely need a PIWIS tester to diagnose and perhaps update the program.

Kessy is keyless? I have the basic version of Cayenne. I have to open and start the car using key.

Porsche Entry & Drive System

The Porsche Entry & Drive system is offered as an optional step-up in convenience (ID-Number for all models); this system offers, in addition to the “Ignition Lock with Single-key System” described above, keyless operation of the vehicle. Porsche Entry & Drive consists of a system using interior and exterior antennas, an integrated identification generator in the vehicle transmitter, proximity sensors as well as a locking button in the exterior door handle surrounds. The driver carries an ID sender (electronic mini transmitter emitting an identification code), which is integrated into the vehicle key.

I don't have Kessy option in my car.

As I recall the antenna for non-Kessy key is in the A-pillar (near the front windshield).

So the rear hatch may not respond as fast - especially to repeated signals.

The response does seem a little weak but maybe close normal. I'll look for other Cayenne owners to chime in here too.

I have a problem with it even if I'm at the driver's door. There used to be heavy rain and I wanted to open the car, but before I opened it I was wet
