No sidebar there my friend, as your picture
and description show, it also has 4 pins. I think
you can ignore the "twin" levers comment unless
your goal is to shim it, which my be a bit tighter.
The 50mm does have 5-pins however, but still
no sidebar.
Now, the company does boast pry resistance,
(twin lever) and security pins (most likely spools).
Look at your lock-50mm-5 pin, 40mm-4pin, and
take a deep breath. What you seem to have is
a decently made padlock, with a 3-4 security pins
at best.
Have a bit of confidence, lighten your tension,
in a day or two you'll get it
