Cant lock hatch 2021 mazda 3
 

Just bought a 2021 Mazda 3 Preferred. It only came with one key fob which does not have a hatch button on it. I also did not find a hatch unlock under the dash. When I lock the car with the key fob, the hatch does not lock. I found a lock button in the hatch lid but it didn't seem to do anything either. Still going through online user manual (ugh) so I may be missing something simple.

Another question, can the 3 button and 4 button key fobs work on my car?
