I have had one of the contact/prongs disconnect at the solder joint but look fine.
Depending on how you were holding the probes to them, you might have been improving the contact.
Gently using a pin, you could pull or push one side away to see if they separate.

Good luck on your beautiful Tall Key unit.

Thank-you Den, I'll try again tomorrow gently, like the flight of a bee
