LIXIL LIX double thumbturn unlocking → kitchen doorGOAL.TTX.5pin unlocking and cylinder replacement

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

It was a detached house unlocking project in the immediate vicinity.There is equipment of TOSTEM LIX double.The upper side is a disc tumbler cylinder and the lower side is an Alpha FB lock cylinder.

Advance special gap unlocking according to the size of smoke guard. I did 20 sets for 2 minutes, but there was no clicking sound. Change to Plan B to unlock the kitchen door.

I can go by picking, but it looks like it will take some time. I gave up on unlocking the thumbturn because the clearance suddenly disappeared, and I switched to unlocking.

Replacing the cylinder took a little time, such as grinding cut, by adjusting the dimensions of the TTX cylinder instead of the AD-5 type.

It took more than 60 minutes including the setup, but the work is completed.In an environment where it is dark and rainy at nightfall, efficiency drops by about 2%, so there seems to be a problem with how to proceed.Let's improve in the future.

After unlocking, TOSTEM was verified, but it seems that the cause is the aged deterioration of the lock case.

Even if the thumbturn rotates 45 degrees, it does not rotate.It stops.Moreover, it was quite hard if it was one-sided.

At a later date, I made a jig to deal with the situation, but I can't confirm whether it turned 45 °.Is there any good way?I wish I had a thin scope camera ...
