Securityman Portable Door Lock with Alarm (2 Pack)
An extra lock on a door that isn’t yours.

How John uses it
Goes with me every time I stay somewhere that isn’t the cabin. Hotel, short-term rental, the occasional motel at the edge of nowhere. The lock itself is mechanical — the alarm is the part that actually matters. 130 dB at 3 AM means nobody’s entering the room quietly whether I’m awake or not.
Sets up in about ten seconds. No tools, no installation, no damage to the door. I take it off in the morning and throw it back in the bag.
Why John recommends it
Hotel locks are not secure — staff keys, master keys, overridable electronics. A portable door lock costs $25 and makes it physically harder to open the door from the outside, regardless of whose key someone has. For anyone who travels alone or stays in places they don’t know well, this is one of the highest-value items you can pack.
