Touch Id Not Working After Logic Board Change Using Paired Sensor Macbook Air 13 Retina Display 2020

Chosen Solution

Hi, I replaced my girlfriends MacBook Air logic board and Touch ID sensor using a spare air I bought off eBay. This spare MacBook Air had a cracked screen is fully original. I’ve moved across the logic board and everything is working fine except TouchID won’t work. I’ve moved across the sensor from the one I bought off eBay, but still no joy. Can anyone advise next steps? Cheers

Ouch! It’s possible the original owner killed the system via iCloud FindMy services given you bought a damaged system. I’m surprised you didn’t first swap out the display to checkout your purchase first. You’ll need to contact the seller.
