Product Overview

High-quality transponder antenna designed for PSA/ Stellantis vehicles. This immobilizer antenna reads the key transponder signal and transmits it to the vehicle’s immobilizer system. It is a direct-fit replacement for a range of PEUGEOT and CITROËN models with multiplexed wiring and is intended for professional installers and DIY mechanics who need reliable anti-theft recognition between key and ECU.

How To Replace

Replacement is straightforward for an experienced mechanic. Typical steps:

• Disconnect the vehicle battery before starting work to avoid electrical damage.
• Remove steering column trim to access the ignition barrel and immobilizer antenna ring.
• Unplug the antenna connector and remove any retaining clips or screws.
• Fit the new antenna in the same orientation as the original; ensure the coil ring sits correctly around the ignition barrel.
• Reconnect the wiring, reassemble trims and reconnect the battery. Verify key recognition and engine start function.

Installation Recommendations

• Always disconnect the battery before disassembly to prevent damage to electronic modules.
• Handle the antenna coil carefully to avoid deforming or cracking the ring; even small damages can impair signal strength.
• Check connector pins and wiring for corrosion or damage and clean contacts if necessary.
• After fitting, test with all vehicle keys to confirm reliable transponder recognition and start sequence.

Why This Part Fails Most Often

• Mechanical damage to the antenna coil or housing (impact, cracked trim, deformation).
• Corroded or broken wiring and connector contacts causing intermittent or no signal transmission.
• Water ingress or long-term exposure to moisture leading to coil shorting or connector failure.
• Wear from repeated removal/reinstallation or improper handling during previous repairs.
• Symptoms of failure: Key not recognized, engine immobilized, intermittent starting problems or fault codes related to the immobilizer system.

Technical Details

• Operating Type: Low-frequency (LF) transponder antenna (typically 125 kHz for PSA immobilizer systems).
• Function: Reads passive key transponder and transmits signal to immobilizer/BCM for authentication.
• Connector: OEM-style PSA connector (exact plug variant depends on model and production year).

Notes

Search by product code for quick matching in parts catalogs. Ensure the part number matches the original antenna before ordering to guarantee fitment and correct operation.
