Aircraft Security LLC manufactures premium high-security Medeco locks with advanced bi-directional key control. Unlike standard locks, these keys must both lift and rotate each tumbler, ensuring only the precisely cut key can operate the lock and making picking extremely difficult. Manufactured from the highest-quality materials, our locks deliver unmatched reliability and security. All kits include the required PMAs and Certificates of Conformity, providing confidence that your aircraft remains secure. Designed by FAA-certified IA aircraft technicians, our complete kits ensure easy and straightforward installation.
Most Challenger 300 series aircraft leave the factory with our High Security Medeco Locks. If not, this is the direct replacement we sell to the factory.
