It does sounds like an intermittent issue with the keyless system.
When any of the components gets replaced, the vehicle needs to be programmed to accept the new components. Otherwise, it will not work. It can even trigger the anti-theft system and keep the vehicle from starting at all. Programming does require special equipment.
The problem with intermittent issues is they are hard to pinpoint. Even if you take it to the dealer and it does not duplicate the issue, they won't be able figure out which component is causing the issue.
The keyless module is located in the cargo area (I have attached diagram below for your reference)
It will be worth checking for any loose connection. However, you do not want to unplug the module as it can trigger the anti-theft system.
You might want to wait and see if this issue becomes frequent. As it is possible that for some interference the keyless system did not work and that might not happen again.
Let me know if you have any questions.
