Description
Transponder antenna for immobilizer for Citroën and Peugeot vehicles. For vehicles with multiplexed network.
High-quality Transponder Antenna (immobilizer antenna) designed for a range of Citroën and Peugeot models. This antenna reads the key transponder and relays the authorization signal to the vehicle immobilizer system via the vehicle network. Ideal for professional workshops and competent DIY mechanics who service PSA group vehicles. Commonly searched by OE numbers such as 9663123380 and 6160C1, this part helps restore reliable key recognition and engine start functions.

Function And Operation
The transponder antenna (antenna coil) is mounted around the ignition cylinder or in the steering column area and is responsible for reading the RFID chip embedded in the vehicle key. When the key is inserted or present, the antenna energizes and receives the key’s code, then communicates this data to the immobilizer control unit over the vehicle’s multiplexed network. If the code is recognized, the immobilizer allows engine start.
Installation Recommendations
Installation should be performed by a trained technician or an experienced DIYer. Basic steps:
- Disconnect the vehicle battery before any work to avoid short circuits and potential damage.
- Remove the necessary dashboard and steering column trim panels to access the antenna coil around the ignition barrel.
- Disconnect the electrical connector and carefully remove the old antenna; avoid pulling on wires or damaging connector terminals.
- Fit the replacement antenna in the same orientation, ensure proper seating and secure any retaining clips or screws.
- Reconnect the connector and reassemble trim. Reconnect the battery and verify key recognition and normal engine start.
Most Common Failure Causes
- Mechanical Damage: Impact or collision can deform or displace the antenna assembly around the ignition barrel.
- Wiring And Connector Issues: Corrosion, broken wires, or poor connector contact prevent reliable communication with the immobilizer.
- Water Ingress And Moisture: Moisture in the steering column or dashboard area can corrode the coil or connector.
- Wear And Age: Over many years, the antenna coil or connector can deteriorate and lose sensitivity.
- Improper Installation: Misalignment or pinched wiring during prior repairs can lead to intermittent recognition problems.
Typical symptom of a failing antenna is intermittent or total inability to start the engine with a valid key, or the vehicle indicating an immobilizer/key fault. There is no fixed replacement interval — replace when malfunction is confirmed or after relevant collision/steering column repairs.
Additional Notes
This part is commonly identified by OE numbers 9663123380 / 6160C1 / 616097; searching by these codes increases the chance of finding the correct fit. Follow manufacturer procedures and safety precautions during removal and installation to avoid damage to the antenna or related electronic systems.
