when I shut the car off, the security indicator light keeps blinking

What is your question?

Have a 2015 Mazda CX5. Today is the first time I noticed this light blinking when i turned the engine off. Looked it up in car manual but do not understand what it means. I have the correct key for the car

What makes this problem better or worse?

Light goes off when I start the car. Back on when I shut it off.

How long has your 2015 Mazda CX-5 had this problem?

Just today
