A vehicle entry/tire pressure monitoring system for a vehicle includes an ECU, LF antennas mounted on the vehicle and being in communication with the ECU, and tire sensors mounted in, on or adjacent respective tires of the vehicle. Each LF antenna is configured to transmit an LF tire sensor wake up field and a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle tire sensor. Each tire sensor includes a two-axis receiver antenna and an RF transmitter configured to transmit an RF signal. Each two-axis receiver antenna is configured such that a first axis of the two-axis antenna is configured to detect a respective LF field transmitted by one of the LF antennas and a second axis of the two-axis antenna is configured to detect a respective LF field transmitted by another of the LF antennas.
