Potential Risks Pertaining to Smart Car Keys and How To Avoid Them?

Smart keys have made our lives easier and more convenient today. However, there are some potential risks of using them that car owners should be aware of. 

Below are a few common and avoidable risks pertaining to automotive keys. 

Unauthorized access of remote entry codes

One of the major concerns with smart car keys is the possibility of remote entry codes being accessed by thieves. These keys use wireless communication to transmit signals between the key and the car, which can be intercepted by hackers to unlock the car. This type of attack is known as a relay attack, which can be done from a distance of up to several hundred feet.

How to avoid it?

To prevent this type of attack, car owners can use a Faraday bag to block the wireless signal from the key when it is not in use. A Faraday bag is a small pouch made of conductive material that blocks electromagnetic signals. When the key is placed inside the bag, it prevents hackers from intercepting the signal. Secondly, car owners can also disable the remote entry feature on their keys when they are not using it.

Exploitation of proximity keys

Another potential risk with smart car keys is the exploitation of proximity keys. Proximity keys use radio frequency identification (RFID) technology to communicate with the car. The key sends a signal to the car when it is within a certain distance, which then unlocks the car doors. However, hackers can exploit this technology by using a signal amplifier, which allows hackers to unlock the car doors and start the engine without the key being present.

How to avoid it?

To prevent this, owners can store their keys in a signal-blocking pouch when not in use. These pouches, also known as Faraday cages, block the radio frequency signals that proximity keys emit, preventing them from being amplified by hackers. Secondly, car owners can also disable the proximity key feature on their cars if they are not using it.

So, one has to be very cautious while using the automatic technology. Also, the car manufacturers need to implement robust security measures in their smart key systems, which includes strong encryption algorithms, multi-factor authentication, and regular software updates to patch any vulnerabilities that are discovered. 

Montreal Auto Keys have been designed with much precision and are capable of averting such situations.
