This is a great case made specifically for the now discontinued Steam Controller, but also fits the Xbox One S controller. It holds it in place to keep it from moving, with pockets to securely store the key, its extension cord, and a spare pair of AA batteries. It's also made so you don't accidentally press the center button and turn it on. Some people have trouble with the key not staying in place. You really have to push it in to lock it, side to side, not all at once. There may be imperfections in some cases, but I haven't had any issues. I suspect the key holder may wear out over time, but the case itself is very durable and protects the controller. Considering that Steam no longer makes the controller and accessories and is only available from third party vendors who usually scalp it, I highly recommend this case to keep them safe!
