Not sure to get your design even when looking at the previous post. The UI element is not supposed to be hidden if locked and/or you don't keep a client side LockList which is updated using SignalR?
For now it seems to me your intent is anyway to always make a server side call making maybe SignalR no more 100% needed ?
You are 100% sure the much usual optimistic approach is not enough for you (maybe slightly adapted if needed).
