Title
MacBook Air 13” Retina Display Late 2018 Touch ID Sensor Replacement
Introduction
Use this guide to replace the Touch ID sensor in a 2018 MacBook Air.
'''Note that Touch ID will not function after replacing the Touch ID sensor.''' The MacBook’s original Touch ID sensor is uniquely paired to the T2 chip on the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement Touch ID sensor from another MacBook Air won’t work.
If you replace the Touch ID sensor, you must install a [product|IF188-142|paired logic board] to retain Touch ID functionality.

Conclusion
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
'''To reassemble your device, follow the above steps in reverse order.'''
Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
