GOAL GV.TXK・SK-TM Double cylinder unlocking

"Unlocking the entrance door by non-carrying a key"

While returning home from his parents' house far away, he seemed to realize that he had left his keys at his parents' house.Naturally, they couldn't go back, so a request was made to unlock the door.According to the information, there was one normal thumbturn, but there were two unlocked places with security thumbturns.

Upon arrival at the site, we interviewed the client and found that there was no need for special unlocking.I proceeded with the normal unlocking process, but the magnetic accessory compartment on the back of the door was getting in the way quite a lot, and I felt the thumbturn shape was odd.I checked it with a camera and it was definitely a TM type.

I will quickly switch to a dedicated tool and proceed.I followed the instructions to unlock from the top, but the bottom required LED lighting.This time I used LED lighting from a door post (it was dark, so next time I'll avoid using the post).
