Care and Maintenance
To ensure the longevity and appearance of your TPU key case cover, follow these maintenance guidelines:
- Cleaning: Wipe the case with a soft, damp cloth to remove dust and dirt. For tougher stains, a mild soap solution can be used, followed by rinsing with clean water and air drying.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the TPU material.
- Storage: When not in use, store the key case in a cool, dry place away from direct sunlight to prevent material degradation.
- Flexibility: The case is made from soft TPU, which is flexible and durable.

The Soft TPU material offers excellent flexibility and durability.
Troubleshooting
- Problem: The key case does not fit my car key.
- Solution: This product is designed for specific BMW E-series remote keys. Refer to the "Important Compatibility Note" in the Introduction section and the accompanying image. If your key does not match the depicted shape, the case is not compatible. Please verify compatibility before purchase.
- Problem: Buttons are difficult to press or misaligned.
- Solution: Ensure the key is correctly seated within the case. Remove the key, realign it carefully, and reinsert it, making sure all buttons correspond to the case's button markings. The flexible TPU should allow for proper alignment.
- Problem: The key signal is weak or not working.
- Solution: The TPU material is designed not to interfere with key signals. First, remove the key case and test your key. If the key works normally without the case, try reinstalling the case, ensuring no foreign objects are trapped inside. If the issue persists, the problem might be with the key itself, not the case.
