In other words, what you are asking for is something like:

I want to securely lock main doors to my house, and my *only* problem
is cylindrical door lock - I have heard that it could be easily picklocked.
So I decided to use big padlock instead. Should I use brass or steel
padlock ? Will 5 pin lock be enough ? Or perhaps two or more padlocks ?
Maybe combine it with card lock or digilock ? Should I attach
thick chain somewhere ? Or connect high voltage to door handle
(that would be automatically activated by *trigger*, of course).
Should I complain to lock manufacturer or door manufacturer
that their products are not secure enough for me ? Thanks for your advices.
Oh, I forget to say that all my windows are wide opened, and anybody
can walk in by back door.

Regards,
Ivan
