Need Help!

Anyone have issue/problem with Toyota Corolla Altis (2009) starting engine problem immobilizer?

I bought this used car last year 2020.

I was given 2 keys.

One key comes with the remote (Black).

Another key no remote in Grey color.

I opened the remote cover to check the battery model & cover it back.

Then I cannot start the engine.

When I used the Grey color key, it can start the engine.

Any one knows how to disable the immobilizer or how to register the black key back?

You need to make another key with an RFID chip cloned from the original (grey).

There are a few shops that does that.

Yes, go to clone a new one.

I did it at a shop at Turf City, it was the cheapest. I asked a few.

The grey colour key is a "service" key.

Grey colour key cannot open or lock the car boot.

Only the black colour key can open, lock and unlock the car boot.

Grey colour key is meant to pass to the service advisor or car mechanic when you service your car.
