Transponders may also be used by residents to enter their [[gated community|gated communities]].{{cn|date=May 2024}} 
However, having more than one transponder causes problems. If a resident's car with simple transponder is parked in the vicinity, any vehicle can come up to the automated gate, triggering the [[Identification friend or foe|gate interrogation signal]], which may get an acceptable response from the resident's car. Such units properly installed might involve [[beamforming]], unique transponders for each vehicle, or simply obliging vehicles to be stored away from the gate.{{cn|date=May 2024}}
