Fix Your Car Issues with These Affordable Fixes

63. Wrap Your Keys In Tin Foil

Items Needed: Tin foil
Est. Price: $2-$5*

This one is a little different from the other hacks on this list, as it isn’t focused on repairing or cleaning your car. Instead, this hack helps with theft prevention. If you have a newer car that unlocks when you approach, that is because your car connects with an electronic signal from your key fob.

Your key fob has a computer chip inside it, which creates a unique code that interfaces with your car’s security system. When the codes link, the car unlocks. Unfortunately, hackers can hack these codes, possibly allowing them to steal your car. If you want to make your keys unhackable, you can wrap them in tinfoil. This might be a good idea if you’re driving in a heavily populated area, where hackers could be lurking.
