App note: Passive entry door system with proximity sensor

A full implementation of a keyless entry from Microchip. Link here (PDF) The door access systems have evolved from simple physical keys to more sophisticated keyless entry systems. Now, we have a system that automatically unlocks the door when user carrying an access key approaches the door handle. As it does not require any user […]

Hacking passive automotive entry/starting systems

The Department of Computer Science at ETH Zurich presents a paper documenting hacking techniques on Passive Keyless Entry and Start Systems (PKES). The hardware setup seems simple enough. The group states: The cable relay was performed with off-the-shelf coaxial cables. We built two 30 m cables that we combined for the 60 m relay tests. […]
