Hi,
I have 2003 Porsche cayenne Turbo that include keyless entry system...

Last week my key battery dies and and i have used my spare key.
yesterday i have replace the battery and my keyless is not working,
Its not open the door and if im tray to start the ignition i get a massage "Key not found"...

If im using the key directly (without the demy key) the key start the ignition and if i press the "open Button" on the key is open the car, the problem is just with the keyless..

Any know how to fix it?

Thank you
