how to make proximity-activated locks except for ultrasonic sensors

Hey guys, any ideas on how to make proximity-activated locks except for ultrasonic sensors? We're trying to make a lock that is activated based on the signal distance of a receiver to the transmitter.

LiDAR if you to have a longer range, or RFID if tap based are some things I can think of. Now that you've specified it to be based on Tx/Rx distance, check out BLE beacon based usage. You can use RSSI values t translate to distance in meters and set a threshold point for door lock/unlock.
