Hands-free Passive Keyless Entry (PKE) is quickly
becoming mainstream in automotive remote keyless
entry applications and is a common option on new
automobile models. Instead of pressing a transmitter
button to unlock or lock a car door, it is possible to gain
vehicle access simply having a valid transponder in
your possession.
