This spy-themed kit allows users to assemble a dual-security lock system with both combination code and key functionality to secure personal items. The set includes electronic components for constructing either a door alarm or pressure plate to protect valuables from unauthorized access. A 32-page instruction manual provides clear guidance for these builds along with additional spy-related activities using common household materials. The kit introduces fundamental concepts of circuitry, information encoding, and decoding while supporting STEM/STEAM learning. Note that 2AA batteries are required but not included with the set.
