L460 Alarm from Engine Bay
 

Hi all, hoping for some guidance on this. Tonight my 2025 Range L460 with 4,200 miles suddenly triggered an alarm from what sounded like the engine bay. It was a loud, high pitched noise that sporadically went off for about 10 minutes (it would go for a minute, then quiet for about 15-20 seconds, and start up again). Ultimately it silenced on its own, but now neither of the key fobs are working and the Remote app is not communicating with the car. The car is sitting in my garage and it's late here so I do not want to manually unlock the driver door with the physical key to avoid triggering the anti theft alarm. But I just wanted to ask if anyone has any experience or has any idea as to what may have caused this. I intend to contact my service center but most times they are unable to do anything unless they can "replicate" the issue. It would be nice to let them know what to look for. Thanks in advance.
