Be exceptionally careful not to slice deep adequate to damage the internal circuit board or copper coils. Extract the Board: Gently move the internal electronic board out of the plastic real estate. Check Under Magnification: Look carefully at the buttons (micro-switches) on the board. You will likely see that a person or more metal legs have split solder joints, separating them from the copper traces on the board.

Should squeeze card for it to work Split solder joints on micro-switches Open the casing and reflow solder on the switches. Physical key blade stuck or missing out on Harmed locking mechanism in the casing Clean the release button or replace the external shell.
