So my google button is worn out, and I've yet to figure out what to call this type of lock so that I can look for a replacement. Basically a push in extends the piston into the plate behind the door, and a turn keeps it from coming back out. The lock itself is fairly worn, I only have one key, and the holes in the plastic spacer are stripped. Any suggestions for a replacement, or help even identifying what a lock like this is called would be much appreciated. Thanks!
