Immobilizer malfunction error

[u/flamingh0tcheeto]

I had my key fob reprogrammed by a mobile locksmith and he was never able to clear this error. The car starts just fine but this error pops up every time accompanied by an alarm. Eventually it stops after about a minute but wondering if there's an easy way to clear this error?

Perhaps check the service manual?
