TPMS Battery

So it appears the battery in my rear TPMS has died. Naturally BMW never planned for the battery to be replaced, but instead requires you to purchase and replace the entire sensor. Just wondering if any one has ever tried to open the sensor and replace the three dollar battery. Imagine I will...

Thks in advance

Don't forget Youtube, it's a wealth of information.

 

 

 

Terminals are attached to batteries with pinpoint ultrasonic welds which apply very focused heat for a brief amount of time. Attempting to solder the terminals spreads a lot of heat over a fairly large area, which cooks the insides of the battery. At best, this will reduce its lifespan.You can’t even get at the underside terminal to solder it, and as I recall, it takes two contacts to complete a circuit.

Counting on a mechanical pressure on a contact that wasn’t designed for it seems like asking for trouble from corrosion or slight separation from impact.

Compared to the cost of the battery, the price for replacing a dead TPM is silly, but at the moment TPM’s are consumables just like tires. Someday there may be a serviceable TPM, but until then, I’ll let the shop replace mine and just grit my teeth over the price.

 

+1 @DukeJockey , You can keep your costs down by replacing a TPMS with a non-OEM unit. I've installed several that I got from @coyotek. All of his TPMS units come with serial numbers to facilitate programming with a GS911.

The one that I got from him did not have to be programmed at all. Just installed it and within a short time, the bike recognized it. I did record the serial number, just in case it would have to be programmed.

 

I purchased a spare k1300 rim with TPM from a forum member. He had noted the serial number for me to program it if needed. As @capav8r experienced, I rode around a bit and the bike picked it up eventually.

 

When I had to replace my front sensor, I looked at these some videos and evaluated how hard it would be to change the battery. Then I discovered that I could buy sensors on eBay for less than $20 each. That saves the hassle to swap the battery and it was no trouble to match it up to the bike.
