I thought I would share (apologies if it’s been stated before) a little addition to the boot release mechanism I fitted as I realised that if the original cable ever broke- I would be screwed getting back in. I purchased an emergency motorcycle brake cable kit for less than a pound. Fitting took about 2 minutes. Simply feed the cable through the latch lever, run the cable around the body to the filler tube. Carefully slip it beween the neck and its rubber sleeve. Pop a lock fitting (in the kit) and you’re done. I didn’t even cut to length, just loop the excess in the middle. Clearly when used in anger the cable will tighten and create a straight path to the latch lever and probably push your boot carpet about a bit, but I can live with that (10 seconds to push back in place). Hope this is of some use. Hopefully photos attached
