The MasterLock MLK5415 is a reinforced, wall-mounted key safe designed for controlled access to keys or access cards. It uses a 4-wheel mechanical combination (4 digits) with up to 10,000 possible codes, so authorised users can be managed simply by changing the code when roles change. No batteries are required.

Built around a solid zinc body with an integrated door, the MLK5415 uses dual locking levers to support a more secure closure. A full-length protective cover helps shield the combination wheels from rain, snow, dust and grime, improving usability outdoors. For best practice, choose a sheltered location where possible, use a non-obvious code, keep it private, change it when access has been shared, and test operation after any code update.

Practical guidance: installation and access control

The Master Lock 5415 works best when installation and code management are treated as a routine. Fix the safe to a solid surface, align it carefully before drilling, and choose a position that is accessible for authorised users but not unnecessarily visible. The 4-wheel mechanical combination (up to 10,000 codes) gives you simple control: share the code only with authorised people and change it whenever users change or access has been shared widely.

The full-length weather cover helps protect the wheels from rain, snow, dust and grime, but a sheltered location is still recommended where possible. Use a non-obvious code, keep it private, and never store it near the safe. After any code update, test opening and closing several times to confirm correct operation before relying on shared access.
