Review: Excellent realtor boxes!! - Master lock boxes are easy to use, install change the codes on and can hold multiple sets of keys. Very sturdy and hard to remove if you do not have the combo for the box. They fit on most door knobs or water spigets. Definitely very secure and functional!!
Review: EXCELLENT KEY SAFE - I'm impressed with the design, features, and build quality of the Masterlock Key Safe. The installation instructions are clear, simple, and easy to follow. I decided to place the safe in a secure location near the front door, not on the door knob itself, but rather to a nearby galvanized water pipe. I've tried it out a couple of times and am pleased with the accessibility and ease of use. I was especially pleased with the tough, rubber-type black cladding that protects the case and the sturdy shackle, and there's even a clever, black cover that slides down to access the 4-digit, rotating combination locking mechanism. And I feel the price is reasonable for such a strong, high-quality product.

## Questions & Answers

**Q: I like the how-to video for setting the combination.  How do I open the U-lock hasp to secure it to the door, hose bib, etc?**
A: Simply rotate the combination given when you PURCHASED the lock......pull....and it opens.  Also, your own combination number is easy to set with knob inside of unit.

**Q: My house key is 2.5 inches long X 1 inch wide and shaped like a car key. Would my house key fit in this product?**
A: The box is 3" x 2 1/2" x 1 1/2" deep, plus some additional space at the top.  You should be able to fit the key in.

**Q: Can the code be changed?**
A: Yes, easily.  When you open the keybox you slide a lever over and then change the combination to anything you want, then slide the lever back and you are done.  So you can use the keybox at different properties and never have the same code.

**Q: How does this work? Want to use it when I leave an elderly relative home in case fall alert is triggered.**
A: It is a sturdy combination lock which you attach to the outer door handle.  Give the customizable combination to your fall alert company, local emergency personnel, and other trusted persons.  It works great
