FUKI/INAHO GOAL-TXK Malfunction due to key deformation

"The key no longer fits in the lock."

It was said that the key suddenly disappeared.Is it malfunctioning due to aging?

When I checked it at the site, it was a cylinder for GOAL TXK,INAHOA cylinder (made of butterbur) was attached.

When I borrowed the key and tried to insert it, it got caught in the front and I couldn't insert it all the way.It was the sensation of being pranked with glue.

Looking through the scope, the inside is like new.No foreign matter was identified.When I checked the key itself, I found that the tip was deformed.Was it under a lot of stress?

I tried fixing it with pliers and it was easy to fix.The material seems to be softer than other brands.

Nagasawa Kodai (KODAI) Tubular Deadbolt and GOAL AD/TX/TXK are also compatible with this product, so it is helpful, but there are concerns about durability.
