Immobiliser bypass plz??

[Poopdog]

After a lot of years the cerb is finally ready for its MOT, but now the bloody thing won’t start, no immobiliser light on dashboard, no fuel priming or turn over.
Everything else works and new fresh battery also.
Can someone pm me the bypass solution so I can at least get it out of the garage

Yeah I think I’ve gone through everything and still no luck, silver key is good it’s just the immobiliser side of things that is preventing start up
