Is it ok to have keyed switch and an electronic imobiliser or will I need to have a steering lock?

I have read the manual but cant quite get my head round what they want!

having a steering lock is not a specific requirement. But 2 forms of immobilisation is

Two form of security. Can be mechanical (ignition lock) or electronic (immobiliser).
No requirement that it has to have a steering lock.

Super - Thanks!

Are you guys sure?
The latest M1 manual (Revision 4, 24/05/2010) says:

"A vehicle MUST be fitted with either a mechanical anti-theft device or an electronic imobiliser"

AFAICS, the manual has never specified 2 forms of security. Or am I missing something?

^^^^^^^^^
I'm with you brother ..........

Check, in addition to the normal “ignition” switch, that the vehicle is permanently fitted with an anti-theft device or an electronic immobiliser that can be activated to prevent the vehicle being driven or moved under its own power.

A mechanical anti-theft device could be a steering lock or transmission lock. An electronic immobiliser can be activated by the ignition key (so would not be obvious) or could be separate - activated by a little fob type device
