     The biros only affect the radial cylinder locks, those with a round key.
 
 If that lock is the one sold with the Almax it's about as secure as locks get, I believe they even surround the lock cylinder in roller bearings so it can't be cut through with a hacksaw, and it's resistant to freeze attacks too (many locks go brittle when frozen with plumber's spray).
