1. Obtain a blank key:
- First, you need to acquire a blank key that is compatible with your Peugeot 107.
- This key should have the correct blade shape and electronics for your vehicle's ignition system.
2. Connect a diagnostic tool:
- Connect a suitable diagnostic tool, such as a Peugeot Planet Diag 2000 or similar diagnostic scanner, to your vehicle's OBD-II port.
- This port is usually located under the dashboard or in the center console.
3. Start the diagnostic tool:
- Once the diagnostic tool is connected, turn on the ignition of your vehicle but do not start the engine.
4. Access the key programming menu:
- Navigate through the diagnostic tool's menu until you find the key programming or immobilizer section.
- Different diagnostic tools may have different menu structures, so consult the user manual for your specific tool.
5. Initiate key programming:
- Select the option to add or program a new key.
- The diagnostic tool may prompt you to enter a security code or PIN to access this feature.
6. Follow on-screen instructions:
- The diagnostic tool will provide you with on-screen instructions to guide you through the key programming process.
- These instructions may vary depending on the diagnostic tool and vehicle model.
7. Insert the new key:
- At some point during the programming process, you will be prompted to insert the new blank key into the ignition.
- Make sure to insert the key all the way and turn it to the "ON" position but do not start the engine.
8. Wait for programming to complete:
- The diagnostic tool will start programming the new key. This process may take several minutes.
- Follow any additional instructions provided by the diagnostic tool.
9. Test the new key:
- Once the programming is complete, turn off the ignition and remove the key.
- Then, try inserting the newly programmed key into the ignition and starting the engine to verify that it works correctly.
Important note: Programming a car key requires precise knowledge and caution. If you are not confident or experienced in dealing with automotive electronics, it's highly recommended to have the key programmed by a professional automotive technician or a certified locksmith with experience in Peugeot vehicles. Incorrect programming or mishandling can cause issues with your vehicle's immobilizer system or electrical components.
