In all my previous cars I can lock the doors with the key fob then open the boot (grab the shopping etc), close the boot and the car remains locked.
Not in the Cayman.
If you open the front boot or rear boot after you have locked the car ( either by fob or key) - the whole car i.e. drivers and passenger doors become unlocked. I have walked away from my car after grabbing my gym gear or shopping not realising I have inadvertently unlocked my doors and left my car vulnerable in a public car park.
Can't see an option to disable this in the car PCM settings?
