Where is the sensor that operates the immobilizer on Renault scenic 2005?

The immobilizer sensor on a 2005 Renault Scenic is typically located within the ignition barrel. This sensor detects the presence of the key's transponder chip when the key is inserted. If the correct key is not detected, the immobilizer system prevents the engine from starting. In some cases, additional components related to the immobilizer may be found in the vehicle's ECU or near the ignition system.
