OPNUS (OPNUS) MMX dark blue key removal and inspection

"The key won’t come out"

It was a newly built property in February of this year.Malfunction due to aged deterioration is not very likely, but the key removal was completed by spray cleaning.

When I ask the client to check the operation, I am trying to pull out in the vertical position many times.It looks like you didn't know how to operate it.

The key is a dark blue "house key", so it is different from the previous trouble with the yellow MEMOLIS key.

Since the MMX cylinder is a rotary disk tumbler, there are many cases of failure due to dirt.

Please check the operation method again.
