"Keyless Go", one of the 'must have' extras on new cars, apparently.
Except that software is now available and being used to nick cars so equipped. It picks up the signal from your keys in the house and amplifies them so the car thinks it's you. Door unlocks, car starts, job done.......
Central locking on my truck is the opposite- it keeps locking the doors even if you keep unlocking them. Probably a preferable 'issue', but I do have to remember not to leave keys in when shutting door......
