JNcylinder breaking and unlocking and cylinder replacement

The client is an old woman who is over 80 years old.It's like a call to talk to the neighborhood because I lost the key.

Since it is a detached house, it will usually be unlocked, but what about this time?

Upon confirmation at the site, there is a WEST decorative lock and a JN cylinder on the wooden entrance door. Is it BH?The target is the unlocking of the lower side.

I will explain the outline while thinking about the method.The door scope also had no choice of swastika attack.Windows were also not an option.

Well, it will be unlocked, but it will not proceed unless you estimate it properly and get consent.Have a neighbor attend and explain to the elderly grandmother.

I got the understanding that "Hi, Hi, I understand" and started work.

Which is the hole saw or the grinder?It's evening, so there isn't much sound around.

All I had to do was prepare a hole saw and remove the lid on the head, and I turned the electric drum, but soon the spindle got bitten.The hole saw is also getting sharper.I move on to the next method, thinking that I have to purchase it even though it costs money.

Change to a grinder.As always, I wish I could cut it quickly, but this time it's not very beautiful either.It's a bad job.

Although it was dangerous, I proceeded with the work while paying attention to the women who were watching nearby. It took about 15 minutes to pull out the core and unlock it.

After that, attach Gold KABA and finish.
