Why your keyless car is vulnerable to hacking
Keyless car entry is one of those convenience things that car makers got totally right. Unfortunately it’s also vulnerable to hacking.
KEYLESS ENTRY IS GREAT. I know women that have never seen their car keys since dropping them in a handbag the day they bought the car, and for for everyone else it’s easy, just keep the key in your pocket and off you go.
All you need to do is walk up to the car, open the door, press the starter button and you’re away. This is known as PKES, or Passive Key Entry/Start, as distinct from an active system where you need to go to the effort of pressing an actual button.
None of the solutions are ideal, and it’s up to the manufacturers to address a weak security issue they created. Here’s the technical research paper on how it can be hacked.
