Low tire pressure warning sensor

With age, plastic has tendency to get brittle and even new might fall apart inside the wheel.

Update on my pressure sensor question.
I discovered the date code on the inside of the tires that were supposedly installed October 2021. They were from 2014, Nitto summer tires. I decided now was the time for something new since I am driving the car about 100 miles per month year round. My local Chevrolet dealer installed a new set of Michelins, currently with a $70 rebate. I can't say enough about my technician, Evan. He let me hang out, making sure the pinch welds were used for lift placement. I showed him the new sensor I had found on ebay and explained the process. He used a small flashlight to look inside each tire until he located the sensor in each wheel (each of which looked perfect). He took great care in removing and installing the new tires. He mentioned how unusual it was for each of the wheel tire combos to take 1/2 ounce of weight or less and reinstalled on the car. He used a torque wrench for the lugs and locking lugs and used a smaller torque wrench for the correct setting for the caps. I couldn't have been happier.
But back to the replacement sensor. You mentioned it didn't need a battery or any maintenance, but I'm still getting the service LTPWS light after a few miles. Should something be "reset" or will the computer eventually "find" the new sensor?
