Unlocked the boot with roof trouble, two options.

If you don't have a code reader etc that will allow you to open the boot when the roof is playing up, these methods have both worked for me, you'll want to make sure your roof is in a position where opening the boot isn't going to cause any damage! Boot access is needed to get to the electrical gubbins and to the pump should you wish to release the pressure to move the roof manually.

Option 1: I’ve done this successfully when the rear screen part of the roof freezes on top of the roof with the boot fully closed. Locate the Hall Sensor on the right hand side ram, put a metal object on the top of the sensor and pop the boot with the key fob……

Option 2: Firstly I got this info elsewhere, I didn't put it together but I have followed the process and it works. Keep in mind doing this is at your own risk! It's a hack but it could get you out of a tricky situation.

Step one - get to the fuse box and locate the connector shown on the underside of the fuse box, it's a long black one with a slide release on the back next to the firewall - X14270

Locate pin 12 - indicated by the red wire

Image

Lower the fuse box and slide it all the way forward and locate the blue 60amp fuse

Image

Connect a tester or similar - a length of wire works - between pin 12 and the blue fuse as shown, you'll hear the boot lock disengage and you're in!

But if boot is locked and no ski hatch you can't reach the escape handle.

true, I did modify that a bit, and led the cable out where it can be reached from outside of the car

No such option on UK cars, I’ve added a additional potential option that’s less invasive/involved.

Can you enlighten others as to what you did? I've only had my car 8 months, and the stories on this forum are scaring me.

Excellent info, maybe worth considering, just in case. My car is in for a rear wing dent repair and I had to show the guy how the roof and boot opening worked. After seeing quite a few threads similar to this, I've been waiting for a call about disconnecting the battery and accidentally shutting the lid. But no one can be that silly right? :D
Also I forgot to disconnect the Smarttop, so it's all or nothing......
Wasn't big damage so I think they can manage
