I doubt its the mechanic messing around. This is a very well established custom truck shop that primarily works on jeeps. These are the kind of people that brand their reputation, go to SEMA and build their own jeeps from ground up. They built this one (in pic) literally chassis first. Why would they mess around? They literally steered me away from buying certain extra stuff for my jeep because they said it wasnt needed lol. They truly look out for their customers and gave me veryyy good deals that various web stores couldnt match. Jus sayinI did some research . There may be a reset TPMS switch somewhere under the steering wheel . Check owners manual if your year of Jeep has one .
Some TPMS require programming by installer .
Some do not .
For certain does not take 100 miles ? Could you imagine how useless Bluetooth in your vehicle would be if it took a 100 miles to recognize your phone .
For whatever reason the receiver is not recognizing the sensors . They should start reading within 2-3 miles tops .
Never ever heard it taking 100 miles . It either recognizes them or not . I purchased a new vehicle few years ago .
Had 7 km on it . Before I drove off the lot I checked everything to make sure all was good .Sensors were displaying accurate tire pressure .
TBH sounds like mechanic is messing around .
