Hey Jameson. Thanks for your reply. Here's the description of the keys I bought from Amazon. They just seem too big. I feel it may be worth buying them from you. Can I return them if they don't fit? 2820 X-Cargo Luggage Roof Replacement Key, X-Cargo Roof Rack Key Karrite Ski Bike xcargo Carrier Skyline Sportrack XL, Replacement Keys for X-Cargo roof Racks [2 Pack] Brand: VIDABTE Special Feature: Anti-Corrosion Lock Type: Key Lock Item dimensions L x W x H: 1.9 x 0.9 x 0.08 inches Material: Metal
