New rims/tires/tpms setup... TPMS Light was on... Now off.?!?

So I bought new rims and tires for my truck and instead of taking apart the stock rims and tires to get the stock tpms, I just bought some new ones on eBay and installed them with the new setup. I got everything installed and after taking the stock wheels tires outta the bed of the truck and selling them, the tpms light came on as expected. I was going to take the truck into the dealer to get the new sensors reprogrammed but after driving a couple hundred miles on the new wheels/tires the light has now turned off. Not sure why since the old sensors are nowhere nearby but has anyone else had something like this happen? Weird

 

When you say nowhere nearby how far is that?
I can get a 40 mile range from my stockers w/ sensors in storage during the summer months (winter wheels & tires).
Once out of range the light blinks. Once back home overnight, the light resets itself.
It is weird for I can park at the trail head 30 miles away from my house, not get a light, park & hike all day, get back to the truck, no light.
This is my experience over the last 5 years on both my tundra and tacoma.

I do not know why you initially triggered the light though

So..if the wheels/tires/sensors I still near you I guess its possible.
