MIWA UR.PG (PGF) 703, cylinder breaking and unlocking stopped, keyed lock case malfunctioning

"Unlocking the entrance door"

It was working this morning, but when I got home the door wouldn't open even when I put the key in.I thought the cylinder was malfunctioning due to deterioration over time, but as I proceeded with the work, it turned out to be quite serious.

Even when I inserted the key, it certainly didn't turn, but I felt something was wrong, as if there was a mechanical collision.I started with normal cleaning of the cylinder, but it doesn't seem to turn at all.

Next, I tried to unlock the thumbturn from the door scope, but it's not a particularly security-resistant thumbturn, and there was no sign of it moving at all.There is no sign of movement even when I turn the thumbturn while checking with the camera.

In this case, we thought that the cam of the lock case had come off or was damaged, so it would not work, so we changed the work method to cylinder breaking and unlocking.It's been about 40 minutes so far.It took about 10 minutes to get back to the worker and set up the lock breaking process.In this case of PG703, the lock breaking area is limited, so proceed with caution. I removed all the inner cylinder parts in about 15 minutes (although this was not necessary).

I used this method because I needed to expose the cam block.You can see the tip of the spindle shaft of the thumbturn on the indoor side.I turn this cam block directly, but it doesn't move at all.I gave it some vibration, but the symptoms didn't improve.

If you proceed any further, the lock case will be scratched.Unfortunately, we are out of stock, so replacement parts will have to be ordered.It will be operated only with the lower cylinder, but delivery will take longer.Work has been canceled because they can't wait until then.In discussions with the management company, we decided to hand over the locksmith's job to another locksmith who has been in and out of business for the reason that the price was cheaper.I heard that it will arrive in the evening after this, but I hope they have it in stock.Are you okay.

Even so, this was the first time I had experienced such a serious incident with a push-pull grip handle lock.
