My wife has a 2002 Chry 300M (recently bought used from a Chrysler dealer) with the tire pressure monitor system in it. The system needs to be retrained with "Special Tool 8821" as the readings do not reflect the correct tire location. This tool was not in the spare tire well like it was supposed to be, and the dealer has been "problematic" with resolving this problem, only suggesting that they *might* be able to sell her a new one if it's available.

Does anyone know a work-around for this tool? WIll any magnet do the trick, or is it a "special" magnet? I have been hesitant to try on my own for fear of messing up the sensors. Any input from anyone in the know is appreciated.

Well, I answered my own question and since I asked, I figured I'd share my results. When I got sick of hearing about how "you said you could find out" I started trying magnets. What I learned was that *any* magnet will do as long as it is strong enough to activate the sensor. The magnet on the back of an old door speaker worked great.

I probably should have tried before posting, but now everyone knows :)

the tool cost less tha $20.00.
what works best is a magnet out of a mopar trans pan with the whole in the center.
these are usually found in shops stuck to the parts washer(trust me on that!!l)(lol)
i'd expect any trans shop to be able to supply one to you.
