## Questions & Answers

**Q: Any one know if this is a combination padlock with a key? If not, why the description has "Resettable" as its special feature? Thank you.**
A: I don't know why it lists that as a feature but this padlock is Non-rekeyable and uses a 4-pin W1 cylinder (as it states in the description). I would generally trust the title, picture and description. Most people don't bother reading the description but I highly suggest it if there is any chance of confusion regarding what need to be bought. The last section called the product details section that lists single variable details is always changing, obtuse, often contradictory - it's also hard if not impossible for sellers to change details in that section so since this product has been around since 2004 maybe once 10 years ago it was "resettable" but probably not, it's probably just the word being used in a strange way.

**Q: Silly question, but are the keys full sized keys like a house key? We need a lock for a treasure chest game at our school carnival.**
A: Hello. The keys aren't quite as large as a house key, but standard size for a padlock. The cylinder for a door knob and padlock are typically sized similarly, so the key will be close.

**Q: Are these locks the 3753?**
A: No idea.

**Q: How much work would it take to cut through this with bolt cutters?**
A: I lost the keys to this lock and easily cut it open with $18 bolt cutters from harbor freight.
