That’s half the battle, appearances. I’m sure you know, given that you are a locksmith, most locks in use are pretty worthless.
The purpose of a room safe like this is to 1) give guests the appearance of caring about security 2) keep the casual five fingered lifter off your stuff. It keeps the guest in the next room from popping in and lifting a few bills or your passport. No it’s not going to keep the home invaders from busting in, holding everyone hostage and then killing you all.
We have had discussions here about why so many guests want locks on their guest room door if they are staying in a room where the host lives. Many hosts express dismay at guests “not trusting them.” Others lament that they have special vintage doors that can’t be retrofitted with modern locks. Most point out that they are going to have key to any lock that they install so what’s the point? The point is appearances.
Half of hosting is a mind game.
