How do we unlock the doors if the car battery dies?


16.5 CX-5 Touring/2023 CX-9 Touring
Hey guys,

I've been thinking about this for a while but how do we open the car doors once the car battery dies? The CX-50 does not have a key built inside of the key fob and the doors do not have a key hole.

I didn't see anything in the owners manual about this as well aside from how to change out the key fob battery. Not sure if I missed anything but let me know your thoughts on this.

I challenge users to try the aux. key in the hole under the door handle. I tried as described in the instructions and it would not unlock it. I have no hand strength issues or injuries.
May need to try a pliers if I try it again, not much area to grasp the key.
