Product information

Description

The MASTER LOCK Extra Large Key Lock Box 5403EURD is a wall-mountable metal key safe finished in black and grey. Measuring 105 x 51 x 146 mm with an interior space of 79 x 42 x 117 mm, it includes a single internal hook and a shutter door to keep multiple house or car keys protected and accessible. The unit uses a 4-digit resettable combination mechanism and a reinforced body designed to resist hammering and sawing.

Advantages

This key lock box provides a large internal compartment that accommodates several keys and keeps them organised on the included hook. The 4-digit resettable combination allows controlled access without keys, while the reinforced metal housing and shutter door increase resistance to forced entry. Wall-mounting capability offers a fixed, convenient location for authorised access.

Suitable for

  • Home key storage for family members or caregivers
  • Car key storage for shared vehicles or valet use
  • Small office or rental property access management
