i think our c max is the same i can use the remote to open the tailgate without unlocking the car and not set the alarm offhmmFriends for stolen, watched the video he had of it being stolen. In through the boot, cut the steering wheel to get the lock off. Must've been less than 5 minutes.
Quite common for people to disable the boot handle on them because of this, loads of people remove the odb port etc too. Sadly very very easy to steal.
For some reason going via the boot doesn't trigger the alarm.
