See if you can tag along to a local locksmith association and network (most offer classes for newbs). Old heads are excellent resources because they’ve seen it all… get their numbers if you can and send them a text (with pics) or give them a call when you get stuck. FaceTime has gotten me out of a few jams… expect some off the wall solutions (whatever. Most of the time they work).
Take pictures, and try to learn proper terminology so they know what you are looking at (any parts catalog can help with this).
Ask questions! If you don’t know something, that’s ok (we all start somewhere and this industry is so vast, no one knows it all). I’ve been doing this for a few years and still feel like a retard sometimes (ok most of the time).
Be aware that some locksmiths are straight up dicks, I’ve seen one in particular in this forum, but they are out there irl. Take it in stride, they didn’t walk out their mothers vaginas knowing how to do jack shit and it’s not you, it’s them.
Most importantly, know when you don’t know! And reach out to someone before you jack up some shit, it’s a lot easier fixing a guided mistake than it is a “welp, let’s try this!”
It’s hard sometimes (especially in the middle of summer when you are essentially in a toaster oven with a raging case of swamp ass) to problem solve quickly. Drink water, up salt in take, change your socks, and drive on.
Best of luck.
