Battery Replacement/Rebuild Wheel Sensor experience?

I have a set of 2000 wheel sensors in my tires and will be replacing the rubber this week.

Because of this, I will have access to my wheel sensors.

While they all still work, I would like to replace the batteries in them myself if this is possible.

Has anyone been able to get to these batteries and replace them successfully?

I know there is a company who does this for around $50 each, but I love "tinkering" with things like this, and if someone can do it, it must have been done by someone else.

Anyone out there with experience rebuilding/replacing batteries in their wheel sensors?

Please Personal E-mail me if you prefer.

Thanks!

Rob

I thought I'd try this, too. The battery on the early sensors is encased in a wax like material. This had to be removed in pieces. The 3V battery is on the right side of the sensor (with the wax side up.) I checked with the local Battery mart; the replacement cost is ~$10, and it has to be special ordered.
I may try an ordinary 3V battery (much thinner) just to see if I can reset the sensor. If it works, I'll probably spring for the $10 battery.
I am debating how to replace the wax. I'm leaning toward using simple paraffin, but I'm not sure of its melting point. I don't want the sensor to melt after a short drive.
Let me know how it works out for you.

High temp hot glue might do the trick in place of the wax.

Wouldn't silicone glue work?

It would hold everything in place????

How did you get the sensor apart?

How are you going to get it all back together?

Where do you get the batteries at?

Thanks for the info!

Great thread!! I am a tinker bell also. Do one of you have pics of the sensor and the area that is (waxed). That would be a good thing. Is the battery a lithium battery? I guess it must be to last as long as it does. Silicone sounds like a good glue to use. It can be taken out if you want in the future.

My 2000 "chimed" r/f tire pressure low. When I checked the pressure it was OK. Does this mean the sensors are "going south?" I'd hate get the warning constantly if that's the case. In my C4 I finally removed the bulb from the DIC

I had one off the old style (C4) sensors come apart in the wheel at 105 MPH. Was a very exciting ride! The stainless steel band broke, so I removed all four sensors.
