K-Cliffs Heavy Duty Metal Key Lock Box Portable 4 Digit Combination Key Realtor's Open House Holds up to 5 Keys

This key lock box is made of zinc alloy and heavy duty steel, which protects it from hammering, sawing, and prying. With 4 combination dials, there are 10,000 possible combinations to choose from! There is enough space for up to 5 house keys or up to 3 car keys depending on the size of your transponder. Keep the key box closed for weather resistance. Change the combination every few months to prevent hijacking. Refrain from creating combinations such as 0-0-0-0 or something easily guessable. Keep a note or take a picture of the set combination in case you forget it (it'll be hard to get your keys back!) Dimensions: 3.94in x 3.15in x 1.97in Weight: 1.10 lbs
