Bitting Variance

The 120/30 and 120/40 share the same keyway but differ in pin count (4 pins vs 5 pins). The 119 series is laminated, cheap, and contains nasty paracentric spool pins. The 120/30 is described as having a keyway similar to an Abus 72/40. Some users note the lock is difficult even for locksmiths.
