Ok so I have in the past upgraded to CCWs with no TPMS and my old TPMS sensors are still sitting in my old wheels, which are also still sitting in my garage. I am thinking about getting them pulled out of the old rims and installing them in the new (CCW's), so that I don't have to keep pushing reset to get rid of the "service TPMS" code that pops up each time I start my car, since I didn't order my new rims with these in them.
Any potential problems with this (using old TPMS's in a different set of rims?) About how much would this swap cost me at a tire shop?
My current tires are fairly new and I don't drive the car all that often, so waiting til they are worn out would not be a great option as far as addressing this.

Thanks

Get new ones. They will last longer. They're ~$70 ea. Dilemma over.

I have a 2000. 1997-2000 TPMS new sensors will run me almost double that (120-140/each?). Its the ones 2001 to 2004 that are 70 a pop. The ones I have work fine...except as I recall, one of them goes out from time to time. Wondering around how much labor at a tire shop usually would run to do the swap. Might be more than its even worth:

Option 1: Use old TPMS sensors. Remove old tires from old rims to uninstall TPMS's. Reinstall tires on old rims.
Remove tires on new rims, take old TPMS's install on new rims, re-install tires on new rims. (probably will end of up running a lot $$)

Option 2: Keep hitting "reset" for error code. When extra cash is absolutely burning a hole in pocket, remove tires, get new TPMS's, install them on new rims, re-install tires.

BLEH! This whole thing really is starting to sound like its more trouble than its worth! I might just deal with it when I need new tires (Whenever that is).

If you have the original sensors in the old wheels, I'd go ahead and pop for a new set of sensors. The original ones have to be fairly close to the end of their life cycle, so save some hassle and just put new ones in. Plus, it saves the cost of breaking the tires from the old set to get the sensors out.

Sensors are good for about 10 years. Depends on how often the car is driven. Go ahead and get new ones. You can get a large magnet to program. Several threads on the forum to tell you how.

I did mine, no problem.

I had new sensors installed in my wheels for $60.

If I was going to the trouble of breaking down my tires and installing the sensors, I'd pop for new ones so I wouldn't have to do it again for a long time.

Pull the old ones out and rebuild them, you can buy new batteries to install from Digikey (not that difficult), new valve steams from http://www.revolutionsupply.com and new O-rings from Lowes or Home Depot.

That's what I did 3 years ago for my 98 sensors and they've been working fine ever since.
