Important Note: Before proceeding, ensure you have a spare set of properly cut Peugeot keys. Disabling the immobilizer should be done as a temporary measure and not as a permanent solution, as it can affect the vehicle's security. The immobilizer is important for theft protection, and disabling it may compromise your vehicle's safety.
1. Locate the Engine Control Unit (ECU):
- Open the bonnet (hood) of your Peugeot 106 and disconnect the negative terminal of the battery.
- Locate the ECU in the engine compartment. It's usually a metal or plastic box attached near the firewall or under the dashboard on the passenger's side.
2. Access the ECU Cables:
- Check for a diagnostic connector near the ECU. It's usually a rectangular-shaped port with multiple pins.
3. Locate Immobilizer Wires:
- Two wires control the immobilizer: the red wire (immobilizer wire) and a black wire (ground wire). Identify these two wires on the diagnostic connector or ECU wiring loom.
4. Disconnect the Immobilizer Wire:
- Using suitable crimping tools, disconnect the red wire (immobilizer wire) from the diagnostic connector or ECU wiring loom.
5. Insulate the Wire:
- Secure the disconnected red wire using electrical tape or heat shrink to prevent it from making accidental contact with any other wire.
6. Restore Battery Connection:
- Reconnect the negative terminal of the battery.
7. Test Functionality:
- Close the bonnet and try to start the car. Both the red and green lights should now be off, and the engine should start if there are no other issues.
Remember: Disabling the immobilizer should be a last resort if the immobilizer system or keys have malfunctioned. For long-term solutions or key-related issues, it is recommended to visit an authorized Peugeot dealer or a reputable auto electrician for professional assistance. Disabling the immobilizer compromises your car's security, so be sure to weigh the risks and benefits carefully.
