Tpms
Just had new new sensors put on and the tire place was unable to reset them and my local dealership doesn’t have a C5 TPMS reset tool. I bought a large magnet with a hole and the first tire will not pick up the magnet. What else could be wrong or what could I do?

To clarify, are any sensors programmed to the car? (you only mentioned the first one not triggering)
Do you know which sensors were installed? Some of the more modern sensors don't use a magnet to program, but will use a different trigger tool like this: This is the tool I bought to trigger the TPMS sensors recently installed on my 2001 Z06. Should mention that I'm not saying this will solve your problem, just using it as a discussion point.

I’m not sure what other sensors could be programmed to the car like the TPMS. To my knowledge these are ACDelco, still metal. The tire shop had a snap on computer that worked similar to the one you linked and it didn’t work, all it said was use magnet.

I meant of the 4 TPMS sensors, did any of them program to the car? It kinda sounded like the 1st one didn't program, and subsequently you stopped and didn't try programming the rest of the sensors.

You don't mention what year your car is, and if TPMS worked prior to this. Give some history on the car, because swapping the 01-04 RFA module into older C5s became a popular mod when the older style sensors became hard to get.
You need to ask whoever installed them what exactly was installed - part #, pictures would be helpful. The ACDelco sensors for the 97-00 cars are very hard to get and expensive so I would speculate they installed something else. Also, I never trust what people tell me they did if I didn't see it happen in person.

2003 and the TPMS went from working to to not reading to not working. The receipt didn’t say what the part numbers were. Yes after the front driver side didn’t work I stopped, I was under the impression that these go in order and you can’t program the passenger side till the driver side is programmed.

The learn process does need to go in order to get the the correct sensors associated to the correct positions in the RFA, but what metalman2 was thinking is maybe one or more of the other sensors does work and possibly you got one that's bad. Maybe try learning the left rear to see if it responds to a tool and / or a magnet. It's closest to the RFA so it's signal should be strongest.
Honestly, if none of them respond to a magnet or TPMS trigger tool, if you bought these installed you should be talking up the person / company that sold them to you.
This is why I recommend everyone train / relearn new sensors to the car before installation so you know they work before they're inside the tire pressure envelope and you have to break the bead to get back at them.
Edit: just curious, the tire shop that had the snap-on tool - were they the ones that sold them to you?

Going out on a limb here but it sounds like it's the tire shop's problem - seems like they got you the wrong sensors. There's nothing special about the 01-04 Y-body TPMS system and there's no need to interface to the ALDL or clone sensor IDs or anything like that. No need for a "dealer" tool either. All you need is 4 compatible sensors that are configured to transmit on 315mhz using FSK modulation with a pressure PID and checksum. Initiate relearn from the DIC and trigger them in sequence. If a magnet doesn't work try a TPMS trigger tool. Print this out and show it to them.
MetalMan2 has a part # for some new / modern, pre-programmed sensors that will work for your application and possibly cheaper than what the tire shop sold you. You will need a TPMS tool to trigger them during relearn.
