I would venture to say yes if they were installed/replaced at the same time. They generally transmit a low-pulse-frequency. It's not the car calling out to the keys every few seconds, but the FOB calling out (transmitting) to the receiver antennas located in the doors and possible roof to activate the sensors. They have to transmit every few seconds because as smart as they are, they don't know when you're next to the car trying to open it.
Wiki:
"The smart key allows the driver to keep the key fob in their pocket when unlocking, locking and starting the vehicle. The key is identified via one of several antennas in the car's bodywork and a radio pulse generator in the key housing"
Edit: If you press the buttons on one more than the other (ex. the other FOB sits in a jar in the kitchen) and have replaced one battery in the one you use the most with buttons, you can just hit a time that both run low at a close time frame. One by calling out to the car, the other calling out and having it's buttons pushed (replacing more, but just hitting the same timing as the first).
