My SRX will be 6 yrs old in October. (although I've only had it since June).
I'm starting to get bogus readings from a couple of the tire pressure sensors. I've heard the batteries are good for 5 years or so.

Any suggestions on a good replacement source?
And part number interchangeability for a 2004 SRX?

Thanks

We checked into the idea of replacing our TPMS sensor batteries when replacing the tires in May 2009; but we were told that the batteries are NOT replacable and that the sensors are very $$$$$. We opted to retain the OEMs. Guess that we will see what the real battery life turns out to be. Our 2005 SRX was assembled in Dec 2004
ps: GM TechLink Magazine (Jan 2003) featured the Hunter system used by Cadillac; the sensor is a sealed unit including the valve stem and is said to use a lithium battery with a 10 year life.

I just installed a new set of sensors for $26 each.

revolutionsupply.com

for my 2004 they are $37 on that website.

Still the original battery is only rated to last 5 yrs.

I replaced mine last year, however I could not program them unless I drove the car first (to activate them) or you may be able activate them with a magnet.

Only then can you pair them with the cars computer (As described in owners manual)

or just have a dealer/tire shop program them

FYI..the instructions in my 2004owner's manual were incorrect :thehand:. It had one of the steps out of order..There are correct instructions on this site.
Saved me a lot of fustration after my initial attempts were unsuccessful.

Thanks! looks like a good source.

Also you need to be concerned about picking up the signal from an adjacent car that my have similar sensors.

Sort of a longshot but it was one of the warnings in my instructions
