But if you know how to reset the GMC Sierra ignition key, you won’t have to worry about doing that many times.
To start with, you need to unplug the headlights and the engine. You can do that by either pulling off the plug of the primary connection or pulling off the terminal on the battery. Next, you need to pull off the ground wire from the negative battery terminal. Once you have these two done, you can then move on to the ignition switch. This can be tricky because some vehicles have a different kind of switch from the others, so make sure that you know how to reset the light by knowing which button needs to be undone.
If it is a generic switch, you need to unhook it from the positive terminal. On the other hand, if it is a special kind of switch, such as a GMC Sierra ignition key, you need to remove the switch’s cover. After that, you need to unscrew the head of the screw from the shaft. Now you can take out the key itself. You should be able to see the switch housing and the wires going to it.
Now you can see where the wire is attached. You can now separate the three wires connected to the switch, namely black, red, and blue. You can then go ahead and remove the cover of the button.

Once you have done this, you need to remove the switch’s cover and then the plastic cover on the bulb.
Once you are done, it is time to remove the screws and remove the light bulb. What you need to do is to place the bulb back and screw the cover back. You should do this procedure slowly.
