Product Overview

The Master Lock 5400EC Lock Box is a great choice for anyone looking to securely store up to five standard 2 inch house keys. It features a combination lock that can be reset for thousands of personalized combinations, making it the perfect solution for those who need multiple key access. The body of the lock box is made from metal for durability, and the shackle is vinyl coated to prevent scratching. An added bonus is the shutter door which helps protect the combination dials from weather.

The exterior dimensions of this lock box are 4 inches 10.2 cm high x 3 inches 8.3 cm wide x 1 inches 4.4 cm deep, with a 13/32 inch 10 mm diameter shackle with 1 13/32 inch 36 mm length and 1 7/8 inch 48 mm width. The internal dimensions are shaped like an L with top section measuring 0.3 inch x 1.56 inch x 2.95 inch, and bottom section measuring 0.95 inch x 1.51 inch x 3.21 inch, providing plenty of room for up to 5 standard house keys in total. The lock box comes pre set to open on 0 0 0 0, but instructions are included on how to reset it if needed.

This product is a great choice for those who need access to multiple keys without having to carry them around all day or worry about losing them or someone else having access to them without permission. It s also ideal for those who want to keep their keys secure while away from home or while on vacation, as it s made from sturdy metal and features a weatherproof shutter door to protect the combination dials from damage caused by rain or snow. Additionally, its vinyl coated shackle prevents scratches that could occur when using regular locks or other types of locks with exposed metal parts that can rust over time if not properly cared for and maintained regularly.

Overall, I highly recommend this product as a secure way of storing your keys while away from home or on vacation as well as keeping them safe from theft or unauthorized access when at home or work. It has plenty of room for multiple house keys and its combination lock makes it easy to reset the code whenever you need it changed so no one else has access unless given permission by you personally. And its metal body provides extra durability and protection against any weather conditions you may encounter while traveling or away from home for extended periods of time, making sure your keys stay safe no matter where you go!
