Kudos to Yakima for immediately mailing me replacement keys for the ones I lost. I got them only two days after placing the order, and at a reasonable cost. If you ever need to replace yours, go straight to their website and click on the link for ordering keys.
I’ve had occasion to use Yakima’s CS a few times over the years. Always a positive experience. Just bought another new rack this year and went straight for the Yakima. They’ve been haulin’ my boats and bikes for a long time now.
