I am changing vehicle in the next week or two. In order to not forget the spare key, I have put it in the glove box already but in a faraday bag. Trying to turn the vehicle on is not possible without my other key.
As it goes, I am getting a new Kuga and that key does not need a bag as it “switches” itself off if motionless for a minute with the same end result as if in a bag/box, thus rendering my two bags surplus to requirements…..
