HIGH LEVEL OF SECURITY: Sturdy zinc alloy construction with 4 internally mounted heavy-duty screws makes the key box with number code highly resistant to hammering, sawing and chiseling. The resettable 4-digit key box allows you to set up your own combination with 10,000 unique options. Feel free to hand over your house keys to your family and loved ones and never have to worry about someone being locked out. EASY TO USE: Easily attach the key security combination to a solid surface with all included mounting hardware and pre-drilled holes. Set up and reset the 4-digit combination in just four steps. Always include instructions. Be careful not to forget your code. Capacity: Replacement key box holds up to 5 keys. You can also store credit cards and USBs. NOTE: Since the top of the interior is occupied by the lock mechanism itself, only items no thicker than 0.5 cm can pass through this section. Long and thick objects such as car remote keys cannot pass through. Weather Resistance: The small outdoor key safe is suitable for outdoor use. High-quality materials are non-corrosive, rust-proof, and weatherproof. And environmentally friendly paint adds resistance. It also features a sliding door that hides and protects the dial from dust, rain, snow and ice during daily use. PERFECT: The key safe is the perfect solution for key hiding and key storage in your Airbnb rental.
