TBH, its quite obvious when you look at the end of the door haha
It isn't really obvious and I can't find it, hence my asking.
Have a look in your user guide! Open the rear door, about halfway down on the edge of the door is a slot. Pop in the end of your key and turn until vertical. Then remove the key. Hey presto!
Most cars with more than two owners don't have all the manuals with them. Mine doesn't have any, I can't find useful ones online apart from advertising brochures in the past, so that's why this site is handy. On a side note, if someone knows where I can buy the manuals, just to have with the car, that would be nice. Cant find them on ebay.
Thanks for the tip, just going to look for this slot now!
