How to Replace an Ignition Switch on a Nissan Sentra GXEby Zyon Silket
The ignition switch on the Nissan Sentra GXE is on the right side of the steering column. It is easy to locate because you place the ignition key into it every time you turn on your vehicle. The lock cylinder goes right through the ignition switch. When you turn the key on, the ignition switch sends an electrical signal from the battery to the starter motor. If the vehicle fails to start, replacing the ignition switch could resolve the issue.
Remove the screws that hold the upper and lower steering column shrouds together using a Phillips screwdriver. Remove both pieces from the Nissan's steering column.
Unplug the wiring harness from the ignition switch. The wiring harness has a lock on each end of the harness. To release the lock, pull up on the tabs.
Remove the screws that secure the ignition switch to the steering column. The screws have tamper-proof Torx heads on them. You can get a screwdriver to remove these screws from most automotive part stores.
Place the ignition switch on a workbench. Insert the ignition key into the lock cylinder and turn it one click clockwise.
Locate the metal spring pin on the bottom of the ignition switch. Push the pin into the switch and pull the lock cylinder halfway out of the ignition switch. Turn the key to the "Off" position and pull the lock cylinder out of the ignition switch.
Place the lock cylinder into the new ignition switch. It will only go in halfway.
Place the ignition key into the lock cylinder, turn it one click clockwise, push in on the metal spring pin and slide the lock cylinder all the way into the ignition switch. This locks the lock cylinder in place.
Secure the ignition switch to the steering column using the tamper-proof screws and the Torx screwdriver.
Plug the wiring harness back into the ignition switch and push down on the locking tabs.
Place the upper and lower shrouds onto the steering column and secure them using the Phillips screwdriver.
