Is is possible that the tpms battery in the new unit is already dead.
A client of mine needed new tpms units in his bike, so decided to order 12 from Aliexpress, use 2 himself and sell the remaining 10 at a small profit to recover the cost of the ones for his own bike.
Good plan, and it would have worked if he had received 12 working units. Unluckily for him, of the 12 he received, only 3 worked. The remainder were all dead.
