You don't know how many keys exist for a hotel room or rental, or who has them. A short routine when you walk in makes the room feel a lot more like yours.
Your arrival checklist
- Test the door. Close it and make sure it latches and locks fully on its own. If it doesn't, ask the front desk for a different room.
- Use the latch or chain whenever you're inside, including during the day.
- Check connecting doors and windows. Make sure adjoining-room doors and any ground-floor or balcony windows lock.
- Don't open the door to unexpected visitors. If someone says they're staff and you didn't call, phone the front desk to confirm.
- Keep your room number private. If a clerk says it out loud at check-in, it's fine to ask for a different room.
Add a layer you control
A portable door lock adds a physical barrier on top of the door's own lock, and a door stop alarm sounds a loud siren if someone tries to push the door open. They can help add protection, but no product can guarantee your safety, so use them along with the habits above. Check that a portable lock is allowed where you're staying, and remove it before you leave or in an emergency.
