What does this icon mean???

So I noticed that my car alarm isn't working properly so I checked out my car locks and I noticed that this icon is shown instead of the regular lock icon...

Can anyone tell me what this means?
Cheers.

Security Indicator Light
This indicator light starts flashing every 2 seconds when the ignition is switched from ON to ACC and the immobilizer system is armed. The light stops flashing when the ignition is switched ON with the correct ignition key.
At this time, the immobilizer system is disarmed and the light illuminates for about 3 seconds and then turns off. If the engine does not start with the correct ignition key, and the security indicator light keeps illuminating or flashing, the system may have a malfunction. Consult an Authorized Mazda Dealer.
