If you believe a small bug in your system is keeping the keyboard lights off, rebooting the Macbook might solve the issue. When your Macbook is turned on, but you are out, the keyboard lights do not work until you come back and begin using your Macbook for yourself. This option allows the computer to save extra power by turning off the keyboard lights while the system is idle.
Beyond this, the options to customize keyboard brightness, as well as setting up a timer for automatic turning on/off the keyboard light, are like the cherry on top. The Macbook lets you set an option to have the system automatically adjust keyboard brightness (increase/decrease) depending on what ambient light is around. Typically, on a MacBook, you will either use F5, F6, or F7 keys to increase/decrease keyboard brightness. Another way of doing this is pressing the Brightness key on your keyboard to increase, and the Dimming Brightness key to decrease.
If you want the backlighting turned up all the way, just keep pressing the decrease key. The first thing you need to do is hit the FN+Spacebar key to toggle backlighting ON or OFF.
Look around your keyboard at any keys at the top of the keyboard that can activate the backlight. If it is already configured in the system, you will have to hold down the Fn key on the keyboard in order to take advantage of built-in controls to the backlighting of F5 and F6 keys. You can easily manually control your MacBooks keyboard backlight via the system preferences, and in order to adjust your lighting settings, you can use the F5 and F6 keys.
To summarize, keep bright light away from your camera area, and your MacBooks keyboards backlight lights will come back on. To enable automatic turning on and off of your keyboards backlight, select the next checkbox for Adjusting the keyboards brightness when there is less light. Then uncheck the box next to Auto-illuminate your keyboard in low light.
If you are having issues with the brightness of your keyboard, you may wish to turn off Adjustment and manage the brightness manually. Although these two options do help to save your battery, it may get pretty annoying while working in a dark room, etc. So, if you are facing keyboard lights do not work issue with your Macbook, you may want to turn off these options and manage brightness by yourself.
If your Mac laptop has backlit keyboard, then you may adjust the level of backlighting while using the Mac in low-light conditions, or you may turn the backlighting off. Now, you must manually adjust backlighting levels with F5 and F6 keys on the keyboard, which becomes the only way you affect the lighting. Since backlighting uses a very small amount of the LEDs energy for lighting, it does not really impact the battery life a lot when the brightness is set at a sensible level or lower, which is why a lot of people prefer the backlit keyboard to show up at all times, even when the lighting situations do not require it.
This might seem a little paradoxical, but turning the controls off gives you complete manual control of the backlit keys, allowing you to set a brightness level that you want to be using the whole time, and that stays consistent whether external lighting conditions affect the sensors or not. By turning off auto-backlighting, it gives full control of backlighting, and you can quickly adjust or set a desired brightness you would like to use. Sometimes sensitivity issues can be solved by using the #3 solution offered below, but the other solution is simply using manual control of the backlights, and turning off auto brightness adjustments.
Sometimes, just tweaking your MacBooks position is not enough, and I have had experiences with some especially stubborn Mac keyboards, where the backlight just did not respond well to outside lighting conditions. Sometimes, a backlit keyboard on a Mac laptop just does not work, seemingly for no obvious reason…and even trying to manually control backlighting using the hotkeys suggests that either that functionality is broken, or that it is turned off. Sometimes, a keyboards backlight may become stuck or become unusable, and the backlight turns off and back on again when the MacBook is restarted.
There is a feature Apple has that involves turning off your devices keyboards backlight from Macbook Air automatically when it is getting too much light, in order to not waste your battery needlessly. This means your MacBook will turn on and off its backlight automatically. In certain situations, direct lighting, bright lights, sunlight, or glare may shine directly at the light sensors in your MacBook Pro or MacBook Air, and when that happens, the lights indicators and controls lock. The Mac uses the camera light sensor to determine how the keyboard and display backlights should be adjusted, if you have these set to Auto, so shining bright lights at the camera should reveal changes to backlight levels.
First, if you have the system set to auto-illuminate your keyboards backlights (which you can do from the System PreferencesKeyboard), check that it is working correctly by shining a bright light at the systems iSight camera, located on top of your display. The easiest way to test that keyboard backlighting is working is to try to turn up the brightness on the backlight, which is usually done by pressing and holding down the Mac notebooks F6 key. Your keyboard likely has buttons for configuring backlighting and its brightness. Backlighting implementations on keyboards varies, but Apple laptops generally feature one LED per key, meaning the brightness is consistent throughout your keyboard.
By default, your MacBook is set to adjust keyboard brightness automatically as light intensity changes. The Keyboard brightness option is a tool that allows you to adjust brightness automatically on MacBook. You will now only be controlling the brightness on the Macbook Airs device keyboard with two keys (F5 and F6).
You can click on the Brightness Reduce buttons multiple times consecutively, in order to completely disable backlighting on the keyboard keys from your devices Macbook Air. If you are facing an early timeout with backlighting, you will have to modify settings in Windows Keyboard properties. Since the best place to start is the most basic of fixes, you will want to manually adjust your keyboards brightness first. For some of you, turning the settings off may be all that matters, particularly if you are using the MacBook to take classes, working in a coffee shop, using an external keyboard, or watching a movie without an available power socket.
Where is the keyboard light sensor on a MacBook Pro?
Select Low-light keyboard brightness adjustment. Make sure this area is not covered if using the automatic adjust option because the light sensor is close to the camera on the top of the MacBook. This technique can also be used to enable the illumination to turn off when some time has passed since you last used the computer.

Where is the light sensor on a MacBook Pro?
To the right of the camera is the sensor, which is 1/2 inch. After pointing the display directly at a bright light, I opened the Display system preference menu by clicking on the Display icon. Moving a small object along the screen’s top caused the brightness to change.
