And do yourself a favor, grab some superglue or other glue (i used a hot glue gun used for crafts) and put some glue on all the other c-clips after making sure they're tight to make sure they dont fly off during some ride.there's a spring clip that hold it in place. look inside your box and hope that it is in there. if not, look at the other locks. they are all the same...just pick out the missing piece and go get it. don't ask me where becausie i have no idea. mine came from the dealer with two extra locks.
