Meet RollJam, the $30 device that jimmies car and garage doors
from Ars Technica
Over the past decade, keyless entry systems have largely displaced traditional physical keys as the means for locking and unlocking cars and garages around the world. Just push a button and the electronic devices transmit a secret code that activates or deactivates the lock, saving people the hassle of manually controlling it. Now, serial hacker Samy Kamkar has devised RollJam, a $30 device that steals the secret codes so attackers can use them to gain unauthorized access to a car or garage.
