Looking for more space to store your keys or access cards? The Master Lock 5403 XXL (XL) is designed to give you one of the largest internal storage spaces in this style of mechanical key safe.

Based on the familiar 4-digit mechanical combination concept, it keeps access simple and reliable (no batteries). The larger compartment is practical for bulkier key sets, longer keys, and access badges/cards that do not fit comfortably in smaller models.

A sliding cover helps protect the mechanism from dirt and moisture, especially when installed outdoors in a sheltered position. Wall-mount installation uses four fixing points for a stable fit.

Key features:

External dimensions: W: 105 mm x H: 146 mm x D: 51 mm
Internal dimensions: W: 79 mm x H: 117 mm x D: 42 mm
4-digit mechanical combination, resettable by the owner
Sliding protective cover for day-to-day protection

Why do key safes come in different sizes?

Key safes are available in a variety of sizes to meet different storage needs. A small key safe can be ideal for one or two keys, while larger models are better when you need to store bulkier key sets or access cards.

Storage capacity:

Larger compartments make it easier to store thick keyrings, longer keys, and access cards without forcing them into a tight space.
Shared access:

For families, care providers, cleaners, and property managers, extra space improves day-to-day usability when multiple people rely on the same safe.
Installation constraints:

Some locations only allow compact units. Where space is available, a larger unit offers more convenience for frequent use.
Different item types:

Modern access often includes cards or badges. An XL compartment is more suitable for mixed contents (keys + cards).
Protection in daily use:

A protective cover and a sheltered mounting location help keep the mechanism cleaner and drier over time.
Ease of setup:

Choosing the right size makes installation and ongoing handling easier, reducing wear and improving reliability.

With a range of sizes available, you can pick the model that best fits your situation—whether you need a compact unit for a single spare key or a larger compartment for key sets and access cards.
