What is foil on doorknob for security?

Foil on a doorknob is a simple and effective security measure that can prevent unauthorized access to your home or office. The idea behind the foil on the doorknob method is that it makes it difficult for would-be intruders to pick the lock or manipulate the doorknob.

By wrapping aluminum foil around your doorknob, you create an obstacle that would-be intruders must overcome before they can gain entry to your home or office. The foil makes it more difficult to grip the doorknob and turn it to open the door.

The method is also effective in preventing lock picking. The foil creates a barrier over the keyhole, making it difficult for lock picking tools to be inserted and manipulated. In addition, the foil can alert you to any tampering with the lock, as you will be able to see if the foil has been disturbed.

It is important to note that while the foil on the doorknob method is a simple and effective security measure, it is not foolproof. For optimal security, it is recommended to use a combination of methods, including an alarm system and sturdy locks, to ensure your home or office is fully protected.
