Door Knob Alarm

Our Door Knob Alarm has been designed for use by travelers and will alert you if anyone should touch the knob of your hotel/motel room door.

This is also an excellent unit to protect you while you are sleeping. Simply place the Door Knob Alarm on your bedroom door or a pre-entry door to alert you the moment the handle is touched. 

Set-up is simple:

• Connect a 9V battery (not included) to the unit.
• Snap the battery cover closed.
• Hang the unit on the door knob.

Note: The alarm will work with any wooden door that has a metal knob (most doors). It may be erratic and undependable on some metal (steel) doors.
