Bin it matey, my advice is buy a good alarmed disc lock, fit a cheap alarm that has no immobiliser circuit & a secret inline switch to fuel pump supply or live feed to coils, it'll achieve same results with less grief with little or no risk of being stranded.
Ageing Meta's are nowt but trouble, mine went Doolally :groan took a bit of unpicking, looms now free of the dreaded Meta & it's in the bin
mash
Easy to bypass if you're not wanting to pull loom apart..
