There's an easy way to always remember your lock combos: Add your birthdate (mm/dd/yy) to each number for your combination lock and write it on the lock. For example, let's assume your birthdate is 5/5/80 and your lock combo is 6-10-23. You can write 11-15-103 on the back of the lock and then if you forget the combo, simply subtract your birthday from the numbers written on the back and pop the lock!
