Hello. I just got my Sparrows Tuxedo starter set and have been trying to pick a 45MM Chinese laminated lock. 4 pins. It seems I can get 3 out of the 4 pins to stick in the chamber, but the last pin keeps springing down and won't set. I tried light pressure, harder pressure, pulsing the tension tool, and it's not setting. I've tried the hook pin, city rake, and snake pin and I just can't seem to get it to open.
Any suggestions? Advice or videos for me to watch would be helpful.
Thank you!
