Owners of 2013 Chevy Equinox vehicles may comment on an intermittent no-crank issue. The design of the key and fob is to have the key extended straight out of the fob. If the key is not in the fully locked-open position at the fob, and the head of the key is angled down, the engine will not crank.
This may simply be caused by the customer contacting the fob release button while inserting the key into the ignition.
If the engine will not crank, remove the key and make sure it is fully extended. Reinsert the key into the ignition in the extended straight-out position. This condition can set DTC B3055 (no transponder or modulation) in history. Clear the code from history.
