immobilizer woes

[Mr Juju]

Hello good people,I rode my Fazer home from work, popped into a shop and when I tried to start it again it refused to play ball.No spark at plugs and immobilizer used to beep but stopped some time ago although bike was still starting ok.Was getting a build up of green corrosion (like when batteries are left in something).Can I bypass the immobilizer or get another unit for the tail piece.Is it a standard fitmit or does anyone know what make it is?links to pics below.Many thanks for your time and attention.
Sorry about earlier links this should work.
