How to replace the remote shell in the spare key of the Opel Astra

The replacement of the remote control shell of the spare fixed key for an Opel Astra is a relatively simple operation. Follow these steps to carry out the replacement: ### Materials needed: - Replacement shell compatible with your Opel Astra - Small flathead screwdriver - Box cutter or sharp knife (optional, to help you separate the shell parts) ### Procedure: 1. **Preparation:** - Make sure you have the correct replacement shell for the model of your Opel Astra. - Find a clean and well-lit work surface to perform the operation. 2. **Opening the old shell:** - Start by opening the old shell. Usually, the shell is made up of two halves that snap together. Use the flathead screwdriver to pry in the groove along the edge of the shell. Gently insert the screwdriver and pry to separate the two halves. If necessary, you can use a box cutter or sharp knife to help start the separation. 3. **Removal of the internal circuit and battery:** - Once the shell is open, carefully remove the internal circuit and 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 in the new replacement shell. Make sure it is properly aligned and positioned. - Insert the battery into the new shell, making sure 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. Make sure all clips snap into place correctly and the shell is completely closed. 6. **Testing the remote control:** - After replacing the shell, test the remote control to ensure it functions properly. Verify that the buttons respond as they should and that the signal is transmitted to the car. ### Additional notes: - **Fixed key:** If the key is an integral part of the shell (as in many Opel models), make sure to transfer it correctly or, if necessary, use the new blade of the replacement shell, having it cut by a professional if needed. - **Safety:** When opening the shell, avoid using too much force to avoid damaging the internal circuit. By following these steps, you should be able to successfully replace the remote control shell of your spare fixed key for the Opel Astra.
