How to Replace the Remote Shell in the Spare Key of the Opel Astra

Replacing the remote shell of the spare fixed key for an Opel Astra is a relatively simple task. Follow these steps to carry out the replacement: ### Materials needed: - Replacement shell compatible with your Opel Astra - Small flathead screwdriver - Utility knife or sharp knife (optional, to help separate the shell parts) ### Procedure: 1. **Preparation:** - Ensure you have the correct replacement shell for your Opel Astra model. - Find a clean, well-lit workspace to carry out the operation. 2. **Opening the old shell:** - Start by opening the old shell.

Usually, the shell consists of two halves that snap together. Use the flathead screwdriver to pry in the gap along the edge of the shell.

Carefully insert the screwdriver and lever to separate the two halves. If necessary, you can use a utility knife or sharp knife to help start the separation. 3. **Removing the internal circuit and battery:** - Once the shell is opened, carefully remove the internal circuit and the battery.

These components will need to be transferred to the new shell. - Be careful not to damage the circuit during this operation. 4. **Transferring components to the new shell:** - Place the internal circuit into the new replacement shell. Ensure it is well aligned and positioned correctly. - Insert the battery into the new shell, ensuring it is oriented correctly (check the polarity). 5. **Closing the new shell:** - Once all components have been transferred to the new shell, align the two halves of the shell and press firmly to close them.

Ensure all clips snap into place correctly and that the shell is completely closed. 6. **Testing the remote:** - After replacing the shell, test the remote to ensure it works correctly. Check that the buttons respond as they should and that the signal is transmitted to the car. ### Additional notes: - **Fixed key:** If the key is integral to the shell (as in many Opel models), ensure you transfer it correctly or, if necessary, use the new blade from the replacement shell, having it cut by a professional if needed. - **Safety:** When opening the shell, avoid using too much force to prevent damaging the internal circuit.

By following these steps, you should be able to successfully replace the remote shell of your spare fixed key for the Opel Astra.
