I have installed the EVO-KEY in a 2010 Hyundia Santa Fe I loaded the firmware 1.06 the recommendedversion 0f 1.05 did not allow the module to see the data signal and the Fortin Tech recommended the 1.06 and that solved the programing issue. The module programs exactly as it is suppose to and the vehical starts and runs great but after an hr or so it does not start and i have to do the reprogram and it works great the after a hr or so it does the same thing reprogram and it works great but the time cycle is the same reprogram works wait an hr and wont start reprogram and works and so on and so on.
