Wonder if the car would start if the FOB is in the engine compartment or outside of the windshield.
Sounds like a test needs to be done.

All these folks trying to help and we get nothing back from Gmathison.
He posted on 11/16 twice and then left.
Why do we bother?

Someday someone will be pulling their hair out and search this problem and the interwebs will bring them to Mazdas247 where a collection of resources and ideas from the brilliant minds of M247's members are archived. Then they'll be able to solve their problem instead of returning to drinking or suicidal thoughts. We're saving lives here man!

lol.Tried a little test. Placed the FOB under the wiper on the drivers side to see if the car would detect the FOB. It did and the car started.
So it's possible the FOB is sitting outside under the wiper blade in that dark area at the bottom of the windshield.

I don't know about the MY of the OP but on my 2020 if the fob is left inside the vehicle for a certain period of time, the engine can't be started to avoid theft. An error message will appear if you try "Key not detected" or something similar and it happened to me before when I did the seasonal tire change. Possibly the fob could be in a bag, pouch, etc. that the OP carries with him every time he drives. For people with a medical condition that never leave without their Epipen or glucometer & insulin for example.Just to prove the fob is not in the torn lining of your coat, may I suggest, you take off all your clothes and leave them in the house and then test the car in your birthday suite. That will prove if the fob is hidding in your coat lining or pockets. What do you think? Let me know. Be creative.

There is something in the owner's manual concerning this very thing. I'm too lazy to get the manual out and look but the above jogged my memory. There's something in there about deactivating the fob if left in the car.

You're right! I didn't think of it this way at all.
Kinda gives me a warm fuzzy feeling inside. Oh wait, that was me spilling my coffee.
How and when would the car know when to deactivate the fob? Maybe if car not in motion for long time? But then, car only wakes up when two things happen: 1) you have the fob near by, AND you press the START button. So I fail to see why car would even try to deactivate fob. What benefit would that have?

Now you've done it! I'm going to have to dig out the owner's manual.

Key Suspend Function
If a key is left in the vehicle, the functions of the key left in the vehicle are temporarily suspended to prevent theft of the vehicle.
To restore the functions, press the unlock button on the functions-suspended key in the vehicle.

The car doesn't 'wake up' just by having the fob nearby. Some action has to take place for the fob to wake the car up. Either pressing the fob button or any of the action buttons on the car.
Same as in my 2020 manual so I suppose this applies to all MY and the two types of fob. No mention after how long but I estimate it could be between 15 minutes to an hour. It took me a little over an hour to do my seasonal tire change when I had the "Key not detected" message.
Not sure what you mean by wake up, but both of my cars "wake up" when I walk towards them with my fob in my hand, or pocket, or whatever. What they do is somewhat programmable. My Lexus for example, unfolds the outside mirrors and unlocks the doors for me. I just walk up to it and get in.

That sounds like a really bad feature. If I've parked my car with the mirrors folded in, it's intentional. I don't want it doing anything unless I affirmatively press a button. I'm thinking of a mirror running right into the pole in the garage, or other object.
You can download the pdf manual and search from phone. I deleted it as so big. Google it for copy.
