If your Jaguar won't double lock and the battery drains overnight, it could indicate a malfunction in the locking mechanism or an issue with the key fob. Additionally, a parasitic draw from an electrical component may be causing the battery drain. It's advisable to check the key fob's battery and ensure it’s functioning properly, then consult a professional technician to diagnose and resolve any underlying electrical issues. Regular maintenance can help prevent such problems in the future.
