If you want to remove the key you have to stick your nails in and try to pry it out rather than having easy access like regular key fobs. This can take a long time. If you then try to plug it back in after using the key, the design flaw is that other keys prevent it from returning to the socket. So those keys get pushed out too and you have to either mess with them or just leave them as they are (because who has time to line up perfectly lined keys every time) and end up with a messy bunch of keys sold as if you were holding keys clean. I bought this for my husband and he hates using it so I have to put all the keys back on the regular keychain.
