Don't expect lock protection warranties to help either because I've never heard of one ever paying out for a bike that was stolen. The reason for that is due to the all the requirements needed to be fulfilled to get them to pay and then only if the company ok's it. Requirements like first sending in the completed form along with the original receipt and UPC code of lock off the box. Then at time of theft send in police report, original receipt and upc code along with the box...wait you sent that stuff in...now what? Next you need to take detailed pics of the crime scene at the same time of the day it was stolen, along with photos of street lighting, public access, the broken undisturbed lock, and whatever the lock was attached to. Send those photos along with the lock...what if they took the lock? too bad! Then you need to send recent photos of the bike, recent appraisal of bike, and the original receipt of bike. Then they get all that stuff and figure out if they should pay or not, and most of the time if not all the time it's a no.

If you use a U lock there is only one best way to use these locks, see this for how: http://www.missinglink.org/page/how-lock-bike
