They installed universal sensors but the light stayed on. They decided to use OEM compatible sensors and the problem was fixed for $316.

Yeah, the batteries start to wear out, about 10-12 years is where you can expect to start to see the tire light come on. If you will have noticed, when you cranked the vehicle up the tire light would blink a certain number of times. This is a code and you can see what the light means. Typically a low battery is the first thing to come up. It will flash when you first crank up, and then go solid. This is a low battery light and with a scan tool you can actually go in and see which one it is. You are right, replacing them all will fix it and get you about another 6-8 years. The aftermarket batteries dont seem to last quite as long as the Denso Toyota do, but they work and get you back on the road without a tire light.
Yes, its still pretty smart to check your pressures because the tire shops just air them up to seat the bead and install and send you on your way. You have to check behind everyone for everything these days.
