Armed with this technology, thieves can enter your car without needing to break a window or bend a door, and they're often able to start the engine.

What is a rolling code grabber?

Do Rolling Code Garage Doors Protect Your Home? Rolling codes change the garage door opener code every time you use the remote control. While this can make finding a correct guess difficult, these systems can be hacked. Hackers can jam the signal with radios, so the system does not roll over to the next code.

How does code hopping work?

A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent replay attacks, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to 'unlock'. Such systems are typical in garage door openers and keyless car entry systems.
