Remote start manual transmission

Hello,

There could be a number of reasons why it is not working. First of all, it could be due to a bad battery on the fob. So, checking the battery should be the first step. This can also be due to a bad module or faulty wiring.
It could also mean that the fob needs to be programmed to the vehicle.
