I got some new rims so I bought new TPMS sensors to go in them. I put one on top of each tire, put the truck into TPMS Re-Lear mode, used my TPMS19 tools at the front left wheel and nothing happens. Tried the other sensors buy moving them to the front left wheel and none of them work (no horn chirp). I bought the sensors from TPMSDirect.com so I'm sure it's not the batteries being dead. They are 315/433 MHz sensors. Any idea why they won't work?
