Thank you for your inquiry regarding the Optex® Wireless Indoor_Outdoor Sensor Transmitters - 18162. Unfortunately, we are not able to guarantee that the sensor that we carry will work with another sensor that was purchased previously from another vendor. I would suggest that you replace the receiver as well to be sure they will work together. Please let us know if we can assist further. Thank you and have a great day!
