@StuartG - is it really a pain unlocking the doors to access the boot? It’s just a different button on the key fob that you need to press.
I never use the ‘boot unlock‘ button when I want to just access the boot. Why you might ask? There’ve been owners on other forums who‘ve used the ‘boot unlock’ button, inadvertently laying their key fob down in the boot, shutting the tailgate and finding the tailgate’s locked and the keys are trapped in the locked car!
I don’t know if the boot should lock in those circumstances (I’m quite surprised it does), but using the ‘unlock doors (+ boot)’ button on the fob means that if you do lay your keys down in the boot and forget to pick them back up (or if they’re in the pocket of a coat you’ve just put in the boot), then with the doors and tailgate unlocked you can still get in the car and also access the boot.
