Description
Central locking controller for Peugeot 3008 T84 and 5008 T87.
Overview
This central locking controller is a direct-fit electrical component designed for early-generation Peugeot 3008 (T84) and 5008 (T87) models. It manages the locking and unlocking commands for the vehicle’s doors and integrates with the vehicle’s comfort and security systems. Commonly searched by OE numbers, this part is suited for professional workshops and experienced DIY mechanics looking for a reliable replacement unit.
Features And Function
- Controls central locking actuators, door lock sensors and remote locking inputs.
- Interfaces with vehicle alarm and convenience systems to coordinate lock/unlock logic.
- Low-power electronic design with connector interface matching original equipment.
- Plug-and-play fit in many cases; some vehicle variants may require initialization.
Compatibility
Primary fitment: Peugeot 3008 I (T84) and Peugeot 5008 I (T87). Use OE/product codes when searching: 96652390ZD, 96652390XT, 6490Z3. Always confirm fitment by matching part numbers listed on the old unit.
Replacement Guide
Replacement is straightforward for an experienced technician. Typical steps:
- Disconnect the negative battery terminal before starting to avoid short circuits and to protect vehicle electronics.
- Remove the necessary trim panels or lower dash covers to gain access to the controller location (commonly under the dash or behind the glovebox depending on vehicle variant).
- Unplug electrical connectors and remove any securing screws or clips.
- Swap the unit and secure it in the original mounting position. Reconnect all connectors firmly and reinstall trim.
- Reconnect the battery and verify functionality: remote locking/unlocking, interior lock switches and any alarm/immobiliser responses.
Installation Recommendations
- Work In A Static-Free Area: Avoid contact with static-sensitive pins on the connector and the module PCB.
- Check Connectors And Wiring: Corroded pins or damaged wiring are a common cause of faults—clean or repair as needed before installing the new unit.
- Follow Manufacturer Procedures: Disconnect the battery before removal and follow Peugeot service recommendations for trim removal to prevent breaking clips or damaging wiring harnesses.
- Diagnostic Check: After installation, run a system check with a compatible diagnostic tool to confirm there are no stored faults related to central locking or CAN/comfort networks.
Programming And Initialization
Many replacements are plug-and-play; however, certain vehicle variants or installations may require initialization or reconfiguration with PSA diagnostic tools (e.g. DiagBox). If remote/key synchronization or comfort functions do not operate correctly after installation, an initialization or coding procedure may be necessary.
Why The Part Fails (Common Causes)
- Moisture Ingress: Water or condensation can corrode connectors or damage internal electronics.
- Connector Corrosion Or Broken Pins: Poor electrical contact leads to intermittent or total failure.
- Electrical Surges Or Short Circuits: Faulty wiring or accessory installations can damage the module.
- Age-Related Component Wear: Electrolytic components and relays can degrade over many years of service.
- Mechanical Damage: Impact or improper handling during previous repairs can break internal components.

Final Notes
This controller is intended for use by professional mechanics and competent DIYers. Proper diagnosis of the cause of the original failure—water ingress, wiring fault, or connector damage—will help avoid repeat failures after replacement. When in doubt about initialization or network-related issues, use a PSA-compatible diagnostic tool to confirm correct operation.
