Other models use the splined key, which came in two flavours (No.11 and 12) differening by the number of splines. The number 12 is the most common, but it may be trial and error.



These sometimes come up on eBay, though the forum traders may have some.

EDIT:
The standard advice these days is to dump the security bolt, whatever type and fit ordinary wheel bolts.

Trikey has about forty two trillion number 12 locking keys, perhaps a slight exaggeration, but he has enough of them
