KEIDEN (KEIDEN) card key type knob lock Unlocking the entrance door

"Lost card key, Unlocking the entrance door"

This time I was completely despised.I don't remember any cases that were so difficult due to the position of the door scope.

The cylinder side is KEIDEN (KEIDEN), but it is a knob lock.I tried this for the first time. Is the thumbturn side ALPHA or GOAL?

Due to the positional relationship of the door scope on the front, I decided to try unlocking in the direction of pushing down another point without selecting the normal point raising and unlocking.

But the thumbturn of the old knob lock was small.Moreover, it is made of resin and is slippery.I already realized this, but even with this in mind, I was unnecessarily obsessed with pushing it down, and it took me over 30 minutes to unlock it.Reflection, isn't it?

I used various openers, tip jigs, and camera jigs in a conceivable way, but they didn't turn around obediently.

The cause was that I did not fully understand the characteristics of the special 8mm lock opener (I have been using it for many years, but I did not pay attention to it). .
The tip is not sufficiently fixed with this opener.I noticed this again during the work. (I was completely off guard) I need some tips.

If it is the knob of the old apartment and the same door scope position as this time, it will be a half special unlock from now on.However, it is not a crime prevention thumbturn, so it will be a standard charge.

By the way, the model number of the attached Alpha ball lock was unknown.It is an old lock that has no carved seal on the front.
