Former police officer advises wrapping car keys in aluminum foil

When you press the unlock button on your remote, electromagnetic waves are emitted to facilitate the unlocking mechanism. These waves, however, can be intercepted and mimicked by car thieves using specialized devices, enabling them to gain access to your vehicle discreetly.


Aluminum Foil: An Unlikely Hero in Car Security


A former American Automobile Association (AAA) police officer advocates a rather straightforward method to avert the cloning of your car’s passcode: enveloping your electronic key or remote in aluminum foil. While it might not scream cutting-edge, the foil creates a barrier, isolating the electromagnetic waves and thus, inhibiting them from being snatched and replicated by potential cybercriminals.


This foil-wrapping technique isn’t just limited to car keys; it’s also utilized to shield credit cards from unauthorized duplication attempts.


While skepticism arises regarding the actuality of car theft through remote control signal duplication, instances validating this concern have indeed been recorded. While aluminum foil might not guarantee absolute efficacy (especially in appliances), in the absence of more advanced tools or methods, it does offer a worthwhile line of defense by wrapping your car keys in it.


So, in the ongoing debate between traditional keys and electronic remotes, where does the safety pendulum swing? Both have their pros and cons, but one thing’s for certain: a little aluminum foil might just be the interim peace of mind you need in our ever-evolving technological landscape.
