Autel IM508 add 2018 to 2021 Subaru smart keys OK

Autel MaxiIM IM508 new test by Steve Sze
2018 to 2021 Subaru smart keys success. Just reset smart box. Wait 15 minutes and success. You can use used keys also!! Best to remove this relay so the stinking horn honking doesn't drive you crazy!!
Need to add.i am in USA and these are USA cars and keys. Tried both aftermarket and factory keys to program up to the car.
Is it safe to assume you are asking, will this AKL? Answer to that question is a big YES. You also only need to program 1 key, key can also be used one. Key can also be a aftermarket one, key can also be programmed to 1 or 100 cars. One key can be a fleet key.
