Guys,
When I got my camper, the Yakima racks did not have keys, either. i got a local locksmith to get the core out. It takes the special core insertion tool from Yakima to actually get them out once picked. On the core, will be the code for the key. usually, a letter followed by 3 numbers like 'A123". I just went to REI, found some cores with the same code, bought them and then I now had keys! Locksmith, 8.50. Cores, about 3o bucks. much cheaper than new racks!
Nice.
