Tpms
I recently changed the original tpms on my 03 sae .bought oem sensors that came preprogrammed, guaranteed. Had them installed and read with trigger tool. Tpms are reading but they will not register to my vette. Have tried several different strength magnetics but not a thing.?????

Just for the sake of our internet diagnosing, can you provide the source & part number from where you purchased your sensors? If they actually are OEM sensors for later C5s, they should pair to your car without issue using a magnet. But I'm attempting to cover the scenario in which the sensors may be wrong for your car.

You might try disconnecting the battery for five minutes or so and try again, the tpms sensors send a signal to the receiver module which then sends it on to the cars electronics.

My guess here is they aren't oem and do not respond to a magnet. You might go back to the shop and have them use their TPMS tool to trigger them when you initiate the relearn procedure w/ the DIC.

Thanks for the info on '03s, JDM!! I learned something today. My 2000 works with magnets. I use the large, circular magnets GM puts in the trans oil pans to trap fine metal particles. Just put it over the valvestem. They're very strong.....

I hate to refute his statement because the tool is most likely what the OP needs, but...
GM used 25731358 / AC Delco 25773946 as oe from 2001 to 2004 for domestic cars. These cannot be triggered by RF, only by a magnet.
I suspect the tire shop sold him universal sensors which lack a reed switch. That doesn't mean they're incompatible, they just can't be triggered with a magnet.

Have never seen a post on this forum claiming that all C5 years can't use a magnet. 01-04 is the same sensor so that can't be true for only 03-04 cars.
Before buying a tool try letting pressure out of the tire while the car is in learn mode. There are some aftermarket sensors that will learn by doing that.

That's worth a try, but I've found most of the universal / programmable sensors I've bought in the last 3-4 years lack that pressure change trigger logic also. Conversely, every sensor made after about 2006 is equipped with a 120khz antenna / trigger system. $10 is a small price to pay to not have to put air back in afterwards.

Not if they have oe sensors in them. I have the four original sensors in my '01's winter tire set, and have a picture of one I pulled out on my phone. I can assure you they do not respond to a 120khz tool.

Which is a completely false statement in the context of oe sensors.
Since there's little to no point in rotating tires side-to-side, and impossible front to back, I suggested @lacebm2 take it back to who installed the sensors and ask them to trigger them with their tool for relearn. That way he's not out of the additional $10 and doesn't have a tool he'll likely never use again sitting in his shop / garage.

Excellent. While that's probably the situation for the OP, we're trying to find the correct solution without spreading bad information. I.E.

I'll tell you what, my $10 paperweight sure came in handy when my young daughter came over in her 2018 Chevy Cruze with an inop tire pressure reading. Sure beat having her take it to the dealership

Thanks, I'll add that tidbit of knowledge to my TPMS document I've been working on for the last 9 months - in your infinite wisdom you were able to determine what amount of someone's time whom you don't even know, is worth $10.
It irritates the F out of me that people like you post blatantly inaccurate answers like you did which are subsequently indexed and then proliferated by search engines all over the world. I'm merely trying to undo the damage by pointing out the inaccuracy, and you take it personally. Do us all a favor and focus your energies on the "Off Topic" forum.

You seem quite wound up about the small things, so continue being "irritated the F out" because I rather like it here.
I've contributed to this forum for nearly 20 years now, off topic included.

If the quality of information you've shared is on par with "-03 doesn't use magnets", perhaps the term "contributing" is a bit generous.
Being "wound up about the small things" is what differentiates knowledge from ignorance.
It's official, you've made me want to sell both my vettes just to disassociate myself from this place.
