Jeff Guestwrote a review of Yakima SKS Lock Cores - 8 pack on October 18, 2018
Familiarity: I've used it once or twice and have initial impressions
All of my racks are pretty much Thule, but I recently got a Yakima bike rack. The Thule lock cores are longer than the Yakima cores, so they won't fit in the rack and visa versa. They install just as easy and work just as good though! I bought the 8 pack even though I only needed 2 locks because eventually I will need more Yakima locks, and now I can keep the future racks on the same key!
