No, Your Rav4 just like mine has absolutely no security system installed. No alarm will sound if doors are opened after locked, nothing. Has a panic button, but that is not an alarm like any other brand of car. The engine immobilizer just means they need your key FOB or a cloned copy is needed to start the engine. If you read all the packages available for every trim model 2021 it does not include the option for an alarm. Most dealers will try to sell you a GPS transponder (KARR short for crap), but it is not an actual security system. Some more honest ones will install actual alarms systems that do not screw up the Toyota passive key-less entry and remote start.
