Just want to know if the keys from "VY or other are rechargable" as i dont use my key very much as other half drives most of the time well last time i went to open via remote nothing happend so i unlocked with other key and started with mine after driving for a bit it locked the car and has been ok for a while now.
Key is out of sync, they have a rolling code which if the key isnt used for a while, it gets of sync, As you did, if you just start the car with the key, it will be back in.
