Anyone know if an aluminum doublewide key will work for a Medicine Cabinet? If not does anyone have any extra Medicine Cabinet keys? I am in need of one. Thanks in advance.

Depends on your lock. Mine doesn't work with the C415A keys, but I have seen some that do.

My keys work in the 4 medicine cabinets I've had, and single towers (Gen 2 and Gen 3, not to be confused with 2.0 and 3.0). My double had the locks removed since it was in a mobile phone store for a while. I have the C415A key too.

awesome, thanks guys.

can't you just change the locks?

Yes, that's plan B.
