These seem to be good quality, I've never had a problem with any of them and they've fit every gun I've tried them on from old bolt actions to new rifles and pistols. Having all the same key is VERY nice and allows me to minimize the number of keys in my range bag, etc. That being said, it does come with 2 keys per lock (6 total) so if you do want to split them up, you have keys for each individual lock.
