The replacement key clicked right into my SKS lock core on the first try, no jiggling needed. Matches the original key's cut exactly, so all my rack accessories lock and unlock smoothly again.

Lost my key somewhere between the garage and the driveway, and this replacement clicked into the lock core like nothing ever happened. Matched the number on my old key exactly, so no re-keying the whole rack.

Lost one key off my roof rack last summer and this single replacement fit the SKS lock core without any fuss. Works fine, though I wish it came in a two-pack so I had a spare.
