Losing the key to one lock core used to mean carrying two keys around, so being able to grab a single replacement and keep everything on the same key is a relief. It clicked into the rack housing without any fuss and matches the key I already had.

Swapped this into my roof rack and now it matches the key I already use for my other accessories, which is exactly what I wanted. Clicked in firmly and the key turns smooth with no wobble.

The core does what it's supposed to and matches the key I already had, so now everything's on one key. Took me a couple tries to get it seated properly, but it locks fine now.
