I have the truck listed above Lariat Supercrew with the key-less entry keypad on the driver door. I currently have one working key fob but wish to replace it due to button wear and tear. The vehicle has electric door locks also. I've followed the steps to enter programming mode from the car manual and the locks do not cycle to indicate programming mode being entered.

I would be willing to pay or donate if someone can help me get this to work.

If the vehicle has an aftermarket alarm tied into the system it could cause an issue because the gem module needs to see an off and on voltage change in order to enter programming mode. If the vehicle does not have an aftermarket alarm tied in, the next course of action would be to retrieve codes from the gem module because there could be a fault that is not allowing the module to enter programming mode, like an alarm activation that was not disabled by a remote or a door ajar switch faulty. I attached the procedure just to be sure you have the same thing.
