Do I need two keys for a 2018 GMC Sierra 2500 Diesel

0 votes
Hi, I"m Looking at adding the fortin Evo all to my truck and i wanted to confirm two things. Firstly when i go to flash the module it says for the T harness THAR-GM5 but fortin gives you instructions for the t harness THAR-GM7 and theres not option to select the GM7 only the 5 could i still use the 7 and flash it as the 5. My second question is do i still need two keys to program or would i be able to just use one

Here is the 3x lock guide for evo-gmt7 and 2018 2500: https://fortin.ca/download/91301/evo-all_ig_tsa_bi_gm7_sierra_1500_2014-2016_a_91301.pdf

 

You will need 1 key to program and the flash link updater to complete the porgramming.

 

I will have the team that manages the selection process at the flasher look into why the GMT7 isnt being displayed for that vehicle. Thank you for bringing this to our attention.
