A:Answer Thank you for your inquiry! The Insignia™ 10.2 Cu. Ft. Garage-Ready Chest Freezer, while a functional appliance, does not come equipped with a built-in locking mechanism. Attempting to install a hasp and lock could potentially compromise the structural integrity of the lid, risking damage or misalignment. Furthermore, any alteration to the lid's surface could disrupt the crucial seal, leading to inefficient operation and potential food spoilage. Importantly, modifying the freezer in this manner could void the manufacturer's warranty, leaving owners without recourse for future repairs. Keith | Insignia Support
