I'm not confessing to be an RS expert or anything but I have just rebuilt a pair of 318 uturns so have done a bit of reading on them!!
I'm pretty sure the damper (the bit the lockout knob attaches to) is different between the turn key & remote lockout forks. You defenately have to change damper if you want to convert a turn key to remote so I'm guessing going back from remote to TK would be the same?!?!?
Any way here's a link to a TK damper if you have no other joy

Also this may be an option???

Failing that give TF Tuned a call they may have something kicking about !!
