I would like to secure some items at work in a small locked box. What would be the hardest pad lock to pick with conventional tools? Thank you very much for your free answer.

Hello Rutha,

Hard to pick may not be the only issue.  What size hole is this lock going into?  You have to use a padlock that fits.

Conventional tools could mean many things.  Hard to pick using standard picks? I'd use an American Lock A7200.  This uses a tubular key which requires a different type of pick.

For more pick resistance use an American Lock A3600 and an ASSA cylinder.

I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.

Please don't submit any automotive or safe questions as these aren't areas that I can help in.

I've run my business the way I wanted, treating everyone as I would like to be treated and knowing that any customer could be my last if I didn't perform my locksmithing duties as I had promised.
