1) unscrew casing and remove
2) use screwdriver at top of key you wish to replace. Wedge in gap to one side and press on other side with finger and key will pop out
3) after trial and error, if hammer is staying down, remove hammer and see if it’s broken
4) buy replacement hammer on eBay (no more than $10).
5) remove another key using step 2 to see exactly how hammer and key should be
6) replace all keys and redo casing
