In the mobile version of Witch's Home, if pressing the silver key did not respond, you could consider the following methods: 1. Confirm that the silver key has been bound. After pressing the silver key in the mobile version of the Witch's Home, a confirmation interface would usually appear to show whether or not to open the corresponding room. If there was no response from the confirmation interface, it might be because the silver key had been bound and could no longer be used. At this time, he needed to rebind the silver key or try to change to another key. 2. Check if the silver key is damaged or lost. If there was a problem with the silver key itself, such as damage, loss, etc., an error message might appear after pressing the silver key, indicating that the corresponding room could not be opened. He needed to change the silver key or find another solution. 3. Try to use other keys to open the corresponding room. In the mobile version of Witch's Home, different keys usually correspond to different rooms, so you can try to use other keys to open the corresponding room to see if it's a silver key problem. If the above methods cannot solve the problem, you may need to contact the game developer or customer service for help.
