Description
Transponder Antenna For Immobilizer Systems For PEUGEOT And CITROËN Vehicles. For Vehicles Without A Multiplexed Network.
This transponder antenna is a direct-fit component designed for Peugeot and Citroën models that use a conventional (non-multiplex) immobilizer system. Ideal for professional workshops and competent DIYers, the unit reads the key transponder signal around the ignition switch and relays it to the immobilizer control module. Replacement of a faulty antenna restores reliable key recognition and eliminates no-start conditions caused by missing transponder communication.
Compact and discreet, the antenna assembly typically mounts around the ignition barrel or column. It is commonly sought by part number (9632487880 / 616069), making it easy to find in catalogs or when ordering spare parts. Technically simple but crucial for vehicle security, this antenna ensures the transponder coil can communicate with the vehicle ECU to permit engine start.

Installation Recommendations
Before starting work, disconnect the battery and wait a few minutes to avoid accidental short circuits. Typical replacement steps:
- Remove the lower steering column trim and any covers around the ignition switch.
- Unplug the antenna connector and detach any retaining clips.
- Replace the antenna with the new unit, ensuring the coil sits concentrically around the ignition barrel.
- Reconnect the connector, reassemble trims and reconnect the battery.
Always follow the vehicle manufacturer’s removal and installation procedure to avoid damage to the ignition barrel, wiring harness, or surrounding components.
Why The Part Most Commonly Fails
Failures are usually caused by mechanical damage to the antenna or connector (from collisions or rough handling during steering column work), corrosion or moisture ingress, broken or fatigued wiring, or degraded solder joints in the coil. Symptoms include intermittent or complete loss of key recognition, immobilizer warning lights, and engine cranking without start.
Practical Notes For Mechanics And DIYers
When replacing the antenna, inspect the connector pins and wiring for corrosion or damage and test continuity where possible. If the immobilizer fault persists after antenna replacement, check the immobilizer control module and key transponder battery/state. Because this part is specific to non-multiplex systems, confirm that the vehicle does not use a multiplexed CAN/BSI configuration before ordering.
