NATS2 removal

Hi,

Was told to join on here for my car.

We have an Auto S14a, but the immobiliser is playing up.

We were going to replace everything, but then seen that you offer a NATS2 removal.

There are posts online that state if you remove it the EML will come on?

Can you confirm if this is the case?

If I got a Stage 1a chip as well, would this prevent any EML?

Thanks
