Title: Great until it wouldn't open
Review: I used this lockbox to store my car key while I was surfing, attaching it to the door handle of my car. It worked great for a couple of months. But after surfing yesterday, when I dialed the combination, I was surprised that it wouldn't open. The wind was coming up and I was shivering in my wet wetsuit. Then in hopeful frustration, I hit the lockbox repeatedly with a rock, and it popped open. I can't trust this key lockbox anymore.
