There may be some product you need to trim in order to get the strip to mount all the way down. Just use a razor knife and cut it away.

Put the bars back on and tighten down with the Torx bolts making sure the sides are even.

Lubricate the lock mechanism while you have the lock off. (You might as well. They get tough to turn.) If there is product on the very ends of the rails, you will need to use the razor knife to cut it off. You only need to clean the bottom half of the end to get the lock to function properly. This only takes a few seconds.

The lock should slide on and work now.

That's it.

Piece of cake.
