3. Setup and Installation
The keyhole cap cover is designed for easy, direct replacement. No special tools are typically required for installation.
- Prepare the Area: Ensure the door handle area is clean and free from dirt or debris.
- Remove Existing Cover (if applicable): If replacing an existing cap, carefully pry it off using a plastic trim removal tool to avoid scratching the paint.
- Align the New Cover: Position the new keyhole cap cover over the keyhole opening on the exterior door handle. Ensure the clips on the back of the cover align with the corresponding slots on the door handle.
- Secure the Cover: Gently press the cap cover into place until you hear or feel it click securely. Verify that it is flush with the door handle surface and does not wobble.


4. Operating Instructions
The keyhole cap cover is a passive component. Once installed, it functions by covering the keyhole, providing a cleaner aesthetic and protecting the keyhole mechanism from environmental elements. No active operation is required.
5. Maintenance
To ensure the longevity and appearance of your keyhole cap cover, follow these simple maintenance guidelines:
- Cleaning: Clean the cap cover with a soft cloth and mild car soap or a general automotive cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Inspection: Periodically check the cap cover to ensure it remains securely attached and free from damage.
- Protection: While durable, extreme impacts can damage the cap. Exercise caution during car washes or when cleaning around the door handles.
6. Troubleshooting
- Cap does not fit:
Ensure your vehicle model and year are listed under the compatible models in the specifications section. Double-check the part number (OEM NO. 51217489341) for accuracy. If the product is incompatible, it may not fit correctly.
- Cap is loose after installation:
Verify that the cap is fully seated and all clips are engaged. Apply gentle, even pressure until it clicks into place. If it remains loose, inspect the clips on the back of the cap and the corresponding slots on the door handle for any damage or obstruction.
- Color mismatch:
Ensure you selected the correct color option when purchasing. Colors may appear slightly different under various lighting conditions or due to screen calibration.
7. User Tips
- Verify Compatibility: Before purchasing, always confirm that your specific BMW model (G20, G21, G26, U06) and year (e.g., 3 Series 2019-2023, 2 Series 2020-2024, 4 Series 2021-2024) are listed as compatible. This helps prevent issues with fitment, as seen in questions regarding compatibility with other BMW models like the i3.
- Gentle Installation: While installation is straightforward, use gentle pressure to avoid damaging the clips or your car's paintwork. A plastic trim tool can be helpful for removing old covers.
