Activity key & battery

Post by stign » Sat Jan 13, 2018 7:58 am

Hi there,

my dealer was not ble to answer this question.
Does an activity key use a battery?
If yes, in which cycles do I have to change this one, before I will stand in front of a locked car :-)

The Activity Key makes use of a passive diode to communicate with the vehicle and thus requires no batteries, so there’s nothing ever to replace.
