Discover the “RollJam” – a tiny hijacker device costing only $30 – which is said to allow its user unrestricted access to any automobile or garage via stolen electronic codes.

Car break-ins are not a mystery anymore. Using a car alarm system may bring more difficulties than benefits. When you are locking your vehicle with the trinket, the vehicle alarm system  receives a special code. That code grabber acts as a passive receiver: when you send such a signals to a car alarm, the receiver code grabber reads that transmission and gets the code. Using a “code grabber” device has been a common practice among thieves for years. “Code grabber” simply catches and replays wireless codes for cars and garage doors. Meanwhile both industries have responded by moving the wireless signals their key fobs use to a system of rolling codes, which means that key code changes with every use any code is rejected if it’s used a second time.
What RollJam does?

How Rolljam is any different from any other hack device? The system it uses is very clever. The device contains two radios. The first blocks the airwaves to prevent the lock from receiving the rolling code sent by the key. Since user can`t unlock the car or garage door, he or she definitely will press the lock or unlock button again. Once RollJam has collected the following rolling code, it uses the second radio to broadcast the earlier rolling code to the lock. After that, RollJam device saves the latter rolling code. Because the code has never been used  by the lock, it remains valid. By repeating  it later—say, after vehicle is locked  and owner walked away—RollJam is able to unlock the car or garage. Kamkar successfully tested the proof-of-concept device on Nissan, Cadillac, Ford, Toyota, Lotus, Volkswagen, and Chrysler vehicles, as well as Cobra and Viper alarm systems and Genie and Liftmaster garage door openers. Results are not optimistic, as  millions of vehicles and garage doors may be vulnerable.
Stay alert while opening you car or garage door. It might take a long time for car companies to update cars, so alarming system can guard against car hijacking technologies as RollJam.
