Wrapping foil around doorknobs when alone is a misleading "hack" often used in clickbait ads to promote actual home security products; the foil itself doesn't provide real protection but might slightly alert you with noise if disturbed, though a determined intruder can easily remove it, making it ineffective compared to actual security measures like cameras or reinforced locks, or simply as a temporary cover when painting. The idea stems from the crinkling sound potentially waking you or making the knob harder to turn quietly, but it's more about catching attention than stopping a break-in.
Wrapping a doorknob in foil is a temporary method to deter intruders and potentially protect metal door hardware from corrosion. It's a visual deterrent that might indicate an attempt to break in, and the foil's texture can be challenging for someone to grasp and turn.

By storing your car keys, fob or card in an aluminium tin (even grandma's old biscuit tins), or a special signal blocking box, the signal between the car and key is blocked.
