4 Pack Lock Cores for Yakima SKS Car Roof Rack System Components, Includes 4 Cylinders Cores, 4 Opening Keys and 1 Control Key (4 Pack)

Worked like they should. Installed quickly and easily.

Bought 2 sets of these for Yakima front mount bike racks and towers. They fit perfectly and work smoothly. Now both my racks and cable locks take one key, as well as my towers taking one key. I highly recommend these to anyone looking to replace the locks on their racks and not wanting to pay the expensive cost from the manufacturer. **Side Note: the only extra thing I had to do was go to a Lock Smith to have the cores removed from one of the bike racks. The blank that comes with these only fit these locks.**

I just want to reiterate earlier reviews that these things are horrible. The master key will allow you to get the lock into the rack but you won’t be able to get the core out again! The little locking wedge doesn’t retract far enough to allow the core to slight out. And you can’t exert any pressure or leverage using the master key because it so easily slides out of the core. The Yakima brand locks are 100% worth the extra money. After having to drill these junk locks out of my rack I switched to actual SKS cores and they work flawlessly and are easily removed! Save your money and buy something else, unless you like a couple hours of frustration if you want to remove them from your rack.

I bought a Yakima bike roof rack that doesn’t come with core and key. These are compatible and cheaper than the yakima is selling.

Works well on my Yakima Highroad rack. A little notchy getting the key in and out, but they are good for the price and seem like they will do the job. None of these rack locks are going to beat a thief, just buys a little time.

Relatively easy to install and it beats the heck out of paying Yakima prices.

The Yakima cylinders are hard to remove with the extra key. I tried to remove these after I put them in and was not successful. I was happy to see that I had four keys for the four locks. It also had the key to insert the cylinders. ( the one that I couldn’t get the cylinders back out with. ) Also a comment, I didn’t think one key worked, but then I discovered I just had to move the part that was trying to locked and then it moved. If I knew I couldn’t remove the cylinders I would have probably spent more and bought the Yakima locks.

Great product

They work, but there's a bit more free play when turning them than the OE locks. There is also a security issue but I won't promote that here, but if you want better security get a numbered stock lock set.

Locks all worked but one is a little finicky and I broke one of the keys trying to open after installing.
