LIXIL Famirock Remote Key Tag Key - Sold Separately

LIXIL Entrance Door FamiLock Standard Key Remote x4
Tag Keys x3

Since I mostly used my smartphone after purchase,
these have not been used and are in beautiful condition.
Only one tag key was used by my child.
The ring part of the keychain is missing, but
it was kept in a bag and is clean.
[I have kept the box, so there is only one.]
