Review: Secure locks. - These locks work well. Combination reset went smoothly. It doesn't appear to have the same vulnerabilities to lock picking as depicted on the internet. It looks secure and of good quality. Any lock can be defeated, eventually. This is enough to keep the honest people honest.
Review: Almost 7 years later still going strong - I beams out in my yard and noticed the two padlocks on my gates. I open them about 4 or 5 times a year and don’t oil the padlock or do any maintenance. They’re just left out in the weather year round and they always work. When I saw them today I realized it had been a long time since I bought them and thought how nice it is that a product actually lasts and I don’t have to think about it ever, much less replace it. So I looked it up and I bought both in August 2018 and here it is almost 7 years later and they still work great and don’t show any signs of wear besides some minor fading. That is what I call a fine product and there aren’t too many out there nowadays since everything became disposable, so I wanted to write this long overdue review since it’s so remarkable to me. Now I will say, they cost $9.49 back in 2018 so the price has doubled, which isn’t great, but that’s the way of things too nowadays so there’s no sense complaining I’m just really happy there are a few solid products still being made out there, and this lock is definitely one of them.

## 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.

### ⭐⭐⭐⭐⭐ Great for sheds.
*by R***Y on March 7, 2016*

This is a review of the Master Lock 178D Set Your Own Combo Padlock. I will do my normal list of specs-cool features and then list a summary as to my thoughts after using. -This is made of die cast metal and has a black finish to help protect it from the outside elements.) -It has a 2” wide die cast case and a 1” shackle. Diameter of the shackle is 5/16”. -Comes with 1 change key. -Operate by using a four digit number combination you set. -Unlike a lot of locks, this is a very well built solid lock designed for outdoor use. -To use, enter the combo and push down the shackle and then pull it up to unlock. Summary – I am using these on my two sheds. The combo is easy to set. You simply unlock the lock – open the shackle, insert the key – turn 90 degrees, set the combo of your choice and then remove the key. I really like this feature as I wanted my two sheds to have the same combo so I do not forget and for simplicity. The movement of the dials has a slight clicking and bump feel as you move the numbers vs. being an easy roll. (Might get smoother with time.) I like this as it is easy to lock your digits in and know they are aligned right. Whatever you do, do not forget the combo. The key is only for changing the code and will not open the lock. I am very happy with this lock and all master locks in general so far. Good make and reliable. Highly recommend.
