Auto iso and key flashing

[J.davis]

Auto iso and key flashing on the back screen.
I can't find a reference in the manual for this.
Anybody got an idea for a D7000?
TIA

A quick answer without looking too far John is that the key symbol flashes when you have pressed the "key" lock button on the camera which protects other files from being deleted or overwritten. I think the same happens when the SD card "lock tab" is engaged.
I don't know any connection with that and auto iso but if the problem persists, check the camera settings and then do a factory reset.

Thanks for the hasty reply Andrew.
The second card had the lock tab at halfway, so camera thought it was locked.
I think the auto iso flash is associated with the shooting mode, but not to sure yet.
