This is immobilizer key. If u want to know further there is small red light beside lcd on dashboard and check the trunk number plate chrome if there is a key hole then ur corolla is not immobilizer equipped it it is plain and doesn't have any hole then your corolla in immobilizer equipped. This confusion is bcz the immobilizer is launched in mid 2016 so that's why some corollas are equipped some are not the key that u r showing is thw indication of immobilizer bcz before the introduction of immobilizer this remote key is only available in 1.8 variants. Aftet that this key was available in Gli and altis 1.6 aswell and Grande got Jack Knife key
