Introduction
If you’re looking for an easy and effective way to deter car thieves, wrapping your car keys in aluminum foil is a great option. This simple step can help to shield your car keys from electromagnetic pulses, which can disable electronic key fobs. Wrapping your keys in foil will also make it more difficult for thieves to use a “code grabber” device to clone your key fob’s signal.
Aluminum foil is inexpensive and easy to find, so there’s no excuse not to give it a try. You can wrap your keys in a few layers of foil, or put them in an aluminum foil-lined container. Just be sure to keep an eye on the foil, as it can be damaged by sharp objects like keys.
What is aluminum foil?
Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum. Usually between 0.00017 and 0.0059 inches thick, aluminum foil is produced in many widths and strengths for literally hundreds of applications. It can be used to wrap food, line baking pans, make insulated sleeves for beverages, cover countertops during painting, seal and store leftovers in the refrigerator or freezer, wrapped around 6-penny nails to prevent rusting, or keep flowers fresh and hydrated.
Aluminum foil’s popularity is partly due to its versatility and ease of use, but also because it provides a lot of benefits and can be used in a variety of different ways.
How does aluminum foil work?
Aluminum foil works by reflecting back the infrared radiation that is coming from your car keys. Infrared radiation is a type of electromagnetic radiation, and it is produced by the heat that is emitted from your car keys. When this heat hits the aluminum foil, it is reflected back towards the keys, and this prevents the heat from being absorbed by your car keys. wrapping your car keys in aluminum foil will help to keep them cooler at night, and this will help to prolong their life.
Benefits of wrapping your car keys in aluminum foil
It may sound like an old wives’ tale, but wrapping your car keys in aluminum foil at night can actually help prevent your car from being stolen. The idea is that the foil will block the signal from your key fob, and make it more difficult for thieves to pick up the signal and unlock your doors.
While this won’t work against all types of car theft, it can be effective against opportunistic thieves who are simply looking for an easy target. If you live in an area with a high rate of car theft, or if you have been a victim of car theft in the past, wrapping your keys in aluminum foil is definitely worth a try.

The idea is that the foil will block the signal from your key fob, making it harder for thieves to break into your car.
