TPMS won't reprogram

I have reason to wonder. S Another forum member just 2 months after I purchased mine from the same supplier also could not get his sensors programmed. It turned out the sensors were 9 years old! I didn't pay that close attention when I got mine (yeah I'm kicking myself). I can only find out when I remove them.

I have a 1" x 2" x 3" ceramic magnet. My wheels are CCW's with the sensor inside the wheel somewhere close by the chromed 90 degree valve stem supplied by CCW using I assume a band or a bracket of some sort. I have never seen them. At any rate, I find I can just stick the magnet between the spokes over top of the valve stem. I don't have to touch the rim or anything. However, the sensors seem to only program when I hold the magnet a certain orientation. I don't know which way but it would be North pole towards the sensor or North pole away from the sensor. I hold the magnet one way and if I don't get a beep I just turn it over and try again.

I just put some C6 ZO6 wheels on my 2004 coupe and bought new tpm sensors from Gene.I also cannot get them to program.I can go through the steps just fine but when I get to the part where you place a magnet by the sensor I get no response.I am using a stack of 1" X 2" X 3/8" magnets six deep.They seem pretty strong,any ideas?

Magnet stack that you describe would seem to be powerful enough to trip the sensor into broadcast mode.
Try starting at another wheel just to verify good/bad sensors.
Possible the units were damaged when mounted? (I hope not for your sake).
Do your remote key fobs function properly?
The Tire sensors & fobs use the same receiver. Usually the receiver is good if one or the other (sensor – fob) functions OK.

Did you try what I said a long time ago? That should narrow it down to which sensors are the problems. I'd bet the batteries are dead in those.
We've said that over and over.. that's really all that can be wrong.

Theses are brand new units! Gene doesnt sell old worn out dead crap.I watched them mount the tires closely so I know the sensors werent damaged either. Gonna try starting at another wheel to see though.

Do ANY of them program at all? If not they're either the wrong ones, you're programming them wrong somehow or receiver is bad. If receiver works for your key fob then you know it isn't that. If you've gotten other sensors to work before then you're probably doing the procedure right. That leaves me to thinking you have the wrong sensors.
Just a guess.

Checked the part numbers,they are correct for the 2004.Maybe after market wheels are interfering somehow?I am going to try the stealership next after I try some different magnets and angle of approach.

It isn't the wheels. Have you ever done this before with previous wheels or anything else? Do any of them program, ever?

I think we are all talking about new sensors. They need to be programmed to the car once they have been installed for the first time. Old sensors which have already been in use don't need to be programmed (they already are). They just need to be re-installed in the same orientation.

Each TPS has a slightly unique code that it transmits. When you put the DIC in the TPS Training mode, it tells you to program the LEFT FRONT sensor first, Once you attach the magnet to the sensor area, it causes the sensor to wake up (there normally OFF unless the tire is rotating or theres a magnet over the sensor for programming) and the RFA receives that unique signal and the BCM remembers where that sensor/signal originates from.
If you stick the right front tire on the left front wheel, the TPS will work and transmit a signal BUT,,,,,,when your right front tire is low,,,,the left front tire will really need the air.
If you remove the right front tire and mount a new right front tire on the same rim and stick that rim/ sensor the same tire location, It will NOT need to be reprogrammed and will continue to work properly. Removing and mounting the tire has nothing to do with sensor operation or sensor programming.
Hopefully when you changed tires, they kept the rims/sensors on the same hub. If not,, you need to program your TPS so that there in the correct area.

Apparently
Do you still have those?!? If so, try them. See if you can get any of them to program at all. even off the tire is just fine. that way you can rule out your technique/magnet strength and also that your receiver, etc is working fine.

WHAT???????????????? How do you SWAP tires on a C5?? (other than tires for the track and back to stock)
