Transponder Antenna For Immobilizer For Peugeot Citroën
Suitable For Peugeot 1007, 307, 807 And Citroën C3, C8
For Vehicles With Multiplex Network
This transponder antenna is a direct-fit electrical component designed for Peugeot and Citroën vehicles equipped with an immobilizer system and a multiplexed network. It receives the RFID/transponder signal from the key and forwards it to the body control/immobilizer electronics so the vehicle can be started. Commonly searched by part numbers, the unit is ideal for professional workshops and DIY mechanics who require a reliable replacement part that restores immobilizer communication.
Key Features
- Direct replacement for original immobilizer transponder antenna on compatible Peugeot and Citroën models.
- Maintains secure reading of key transponder signal for proper immobilizer function.
- Plug-and-play electrical connector and mounting points that match OEM locations.
- Saves diagnostic time by restoring proper antenna-to-module communication when unit or wiring is faulty.
Installation Overview
The antenna is typically mounted around the ignition barrel or on the steering column trim, depending on model. Basic replacement steps: disconnect the vehicle battery, remove the lower steering column covers to access the ignition area, unplug the antenna connector, remove any retaining screws or clips, replace the antenna with the new unit, secure mounting, reconnect the connector and restore the battery. After installation, verify immobilizer status by turning the ignition to confirm the vehicle recognizes the key and starts normally.

Installation Recommendations
Always disconnect the negative battery terminal before beginning work to avoid short circuits and unintended module states. Use plastic trim tools to remove covers to prevent damage. Ensure connectors are clean and fully engaged; secure wiring away from moving parts and sharp edges. After installation, perform a functional check: insert key, verify immobilizer LED behavior and that engine starts. If immobilizer faults persist, check wiring continuity and module communication before replacing additional components.
Most Common Causes Of Failure
Failures are usually caused by water ingress, corrosion of the connector, physical damage from impacts or wear in the steering column area, or wiring faults from chafing and connector looseness. In some cases, failures are traced to faulty communication with the vehicle’s body control module due to connector corrosion or broken wires rather than the antenna itself.
