Thanks for the replies and the input, guys. I will consider all of them.

jlo1, you've got a good idea there. I'll find out first if the cable lock will fit under the plastic cover which one places on the spare tire.

Otep, will look for that keyed lock that your're talking about. SM Ace, you say? What part of Ace do I go to to look for it? Is it together with the other car accessories?
