new to Trailblazer. Mechanic supposedly replaced the bad sensor but didn't reset the system / turn off the light.
they said they needed a FOB but i got rid of my OEM FOBs a long time ago. I tried the headlight switch / pressure release procedure but not all the tires register.

can i purchase a FOB off of ebay that will work with my truck to help reset the issue? are they programmable to my vehicle?

what about the TPMS Relearn tools, would one of those help?

anything i'm missing? any tricks or tips i may be missing with the headlight switch/release/beep method (i only get one tire to beep)?

this will work to register the tpm but you still need something to put it into learn mode.

any prompts in the driver information center controls.

 

ok thanks. is the FOB something that will put it in learn mode?

 

if the vehicle has remote entry equipped from factory.

 

ok thanks it does. i need to find the OEM FOB or buy one it was switched to an aftermarket remote start one.
