Product:  Passive Entry and Start System

Passive entry and start systems allow a driver to lock and unlock a vehicle's doors without touching a key, and start and stop the vehicle engine just by pushing an ignition button. This enhances driver convenience by making vehicle entry easier, and helps prevent vehicle theft. 

DENSO's "passive key" detects the low-power signal emitted from the vehicle when the driver approaches the vehicle. It responds to the vehicle by emitting a key code.

The vehicle's receiver accepts the key code, and sends it to an entry electronic control unit (ECU). When the entry ECU confirms the key code, the driver touches the door handle and the entry ECU immediately unlocks the doors.

To start the vehicle's engine, the driver simply pushes an ignition button. No key needs to be inserted into the ignition. The start ECU allows the engine to start only when the key code is re-confirmed.

DENSO supplies the passive key, receiver, entry ECU and start ECU for the system.
