Hi @Yassir14
Welcome to the Community Center.
I'm sorry to hear that you've had a problem with your keys being locked in by a guest, that would have been really frustrating to deal with.
I just wanted to let you know that the Community Center is a space for Hosts to support and help each other with Host-related issues, it's not a formal branch of Airbnb Support. Hosts are encouraged to reply to their fellow Hosts to provide advice on what's worked for them, as well as sharing their own knowledge of Airbnb's workings.
In this case @Mike-And-Jane0 has come to give you the benefit of their experience, as they're a very experienced host. I can't see that they've said anything offensive and have given you their advice on what they think you should do. If the advice isn't quite what you're looking for, that's fine, but we ask that our members keep the Community Center Guidelines in mind and be kind and respectful even if they disagree with what another member has said.
I hope that Airbnb come back to you soon with an update.
Jenny
