Have you forgotten the code for your TSA lock? All you need is a pen and a sharp light. Make sure you look for the indents from the left side of the dials, not the right side. I go through this in detail in this video. Each dial has 10 digits on it. From 0 to 9 makes ten. Slide the dial until you see an indent, then go 5 digits back. That's your number. Do that for all three dials and you've picked the lock. This is the product on Amazon I was working on when changing the lock: amzn.to/3VzWAVt
