good evening I have a car in the workshop Hyundai IX 20 14 petrol Year 2012 Engine code G4FA

The above-mentioned car broke down with a dead battery after replacing the battery with an M.M. ETS 62 R

Car won't start, Diagnosis in Immo System gives me Error P1678 (should be key not recognised)

and at start-up it only has a one-second cue on the motor and then it locks, i.e. the motor cannot turn

giving direct power on 50 of the motor the motor runs but the car still does not start.........

I think something happened to the immo or key code

Does anyone have any advice on this subject???????????

Thank you

Best Regards
