**Q: How does this work? Want to use it when I leave an elderly relative home in case fall alert is triggered.**
A: It is a sturdy combination lock which you attach to the outer door handle.  Give the customizable combination to your fall alert company, local emergency personnel, and other trusted persons.  It works great
