^ Rotate the ignition lock cylinder while the key is inserted to insure that the correct code is read in all positions.

^ If code is correct in all positions. proceed to step 4.

^ If the code shows "E" or is erratic in some positions. Obtain a spare key or make a replacement key.) See Key Duplication Procedure. Read the code again while rotating the ignition lock cylinder with the spare replacement key. A correct code in all position indicates that the original key was defective. An incorrect code indicates a defective lock cylinder. Replace defective lock cylinder.
