(035) Medeco Biaxial picked and gutted

This is an old Medeco Biaxial mortise cylinder I got second hand a long time ago, I just discovered a trick that makes it much easier to get it open. This appears to be the 10W100 model (Biaxial 1" mortise cylinder), many people refer to it as the "51S" because of the Underwirter's Laboratory (UL) code stamped on the front.

The technique is simple and should work regardless of whether you are trying to set the pins on an Original, Biaxial or even M3 and the newer ARX pins won't stop you either. As I demonstrate in the video, after making sure that the pins are all moving freely do the following:
1. Apply heavy tension
2. run a bogata style rake the length of the lock, pressing upwards, on each side of the keyway
3. repeat 2 until you feel all or most of the pins resisting firmly
4. Using a hook, attempt to set each pin to the shearline, being careful to avoid rotating any of them as you do so.
5. With luck, the lock will open.

Since this lock was second hand it seems to have been repaired without any of the mushroom pins commonly found in Medeco's locks which did make the demo easier but I have tried this on several sample locks and it does still work.
