## Questions & Answers

**Q: If this does not work on our travel trail is it returnable?**
A: It will it's universal

**Q: Does this fit Airstreams?**
A: I'm not sure what size the hookup is on an Austrian, but it did not fit my 27ft travel trailer, so I use it on my boat trailer instead

**Q: Can these be rekeyed?  I have alot of locks. All on same master lock key**
A: I have 6 of these they can be rekeyed. Try a different lock smith. I would also say to have it keyed with the pad locks so you always only have one key for lots of locks.

**Q: Can I get a key number the same as locks i Have**
A: It would depend on the key # needed. Please feel free to message us with the key # you are looking to match to and we can tell you if it can be done.
