## Questions & Answers

**Q: Does this lock have any harmful chemicals Prop 65**
A: Don’t put it in your drink or cook with it, if it mixes into your drink or food it could make you sick but I believe the report said you’d have to do that 834 times to have a negative affect on you. 
But on a side note I read just the paper from the Prop 65 rule could make you violently sick if you eat all the paper in just one setting.

**Q: Is it for outdoor use?**
A: It hasn't fared well for us. We have an older one which held up for about 3 years before needing to be replaced. The lifetime warranty allows you only one replacement, so it really isn't a lifetime warranty at all. If you live near the beach, consider yourself lucky if it works for 2-3 years. That said, it is for outdoor use, just expect to lubricate frequently especially after rain or if you live near saltwater.

**Q: What's the diameter of the shackle? I need to make sure it can fit through a hole in a security box.**
A: 5/16"http://www.allpadlocks.com/cgi-bin/ez-catalog/product_images.cgi?account=X380790;product_id=M178;image=images%2Fcatalog%2F178sketch.jpg

**Q: Lost the change key -- how to reset the combo without it?**
A: you can just use a small screwdriver to push in and change the combo while doing so. The Key really just holds down the bar inside for you.

### ⭐⭐⭐⭐⭐ Works like a charm
*by H***N on November 23, 2025*

These are pretty solid. Like how I can set my own combo. I've purchased about 6 of these over the years. After a season outside, the numbers get a little hard to turn. Just hit it with a little wd40 and you're good for another season
