B9 bsi reset without remote locking

[paradox1001]

Hi everyone 
I want to do a bsi reset in my 2009 b9 berlingo.
The reset procedure apparently involves pressing the lock button on the key/keyfob
My berlingo doesn’t have remote central locking so what should the bsi reset procedure be?

Is the horn function controlled by the bsi ?

Are you having trouble with the horn?

I went through a morning of hell with this problem only to return back to the fuse which looked fine but was blown.
Look at the thread above for more causes.
Sometimes these things are just oxidized connectors that a wriggle will rectify but brace yourself for getting your hands dirty...

Does anyone know the bait reset procedure when you don’t have remote central locking please
