Last pin refuses to set
So i bought a practice lock and it's a perfectly good lock, works fine so this is down to user error, but seeing as I've not been doing this too long, thought I'd seek out some help from the vets.
Basically it's a 6 pin euro lock, i set the other 5 pins, then the front pin (closest to the key opening) just wont set. I've tried applying tension from the top, and bottom, tried different amounts of tension but it just slips back down.
I'm also aware of binding pins etc but surely if the other pins are up then the last 'has' to set?
Any help would be GREATLY appreciated.
Also, the plug rotates both ways to open and I've tried tension from both ways.
Thanks in advance!
