Hyundai i20 2013. Battery 6months old and tested good. New key programed. ECU replaced about a year ago.
Car does not start on ocassions until i fiddle with the key in the ignition little.
When ignition is on switch the imobiliser light is off car will not crank or anything. After a bit of fiddling and removing the key and put it back in then imobiliser light turns on and car starts normally.
I got a new key and got it programed and same problem. On occasions. Got a mechanic to check the car battery and its good.
N.b this happens only at times.
