A protective cover shields the combination dial from unpredictable weather conditions. 【Large Capacity】: The capacity of the large outdoor key box is large enough (inner size is about 11.5 x 8 x 4.3 cm), which can accommodate house keys, office keys, or other large car keys; if needed, you can also store some small items, such as credit cards, ID cards, etc. 【Two Unlocking Modes】: This key safe has a 4-digit combination and an emergency key; it allows you to set up to 9,999 combinations.

It allows you to store your car keys safely while surfing, instead of risking hiding them in the sand/under rocks, etc. 【Easy to Install】: This outdoor key safe comes with 4 screws and 4 nylon wall anchors to ensure the key box can be installed on any solid surface. A box can be drilled into the wall for a little more money without hassle or extra work.
