What cause the vehicle not to start or not turn off?

Question

Vehicle was fitted with Fortin Evo-All THAR NIS4(includes THarness) with RF-ALL. 11 months later, the vehicle will not start and will not turn off with "Smart Key error" and "Key not found". Vehicle towed to the dealership and determined that the  remote starter was causing the ground and preventing the car to start. Issue was resolve by disconnecting the remote starter. Should I try to reconnect again and risk of repeating the no start issue?
