Wrong Key Stuck In Door. Open the Control Panel then double-click the Keyboard icon. Avoid pulling hard which merely binds the key against the lock pins.
I would suggest taking the lock into a locksmith as they will have the know how tools and parts necessary to fix the issue. When a key is stuck in a pin-tumbler lock what that usually means is that one of the pins has dropped down into the keys cuts but isnt lifting back out of the way so the key can be withdrawn. The key will easily come out.
This is the amount of time that the OS waits when a key is depressed before activating the key again.
A single or double-hooked extractor should remove the key. This should remove the key fragment but it may take several attempts. Also fwiw pick set legality varies depending on local law. Try pushing on the locks face just next to the key as you pull on the key.
