door sensor

We have 4 door sensors and one of the doors sensors requires a new battery every 3 months while the other last for years.  Can we replace this door sensor?

@user_xdubd7 Thank you for making us aware you're noticing issues with the battery life on this particular sensor. We can look into troubleshooting this device before you commit to purchasing a new one if you'd like. Have you tried resetting the door sensor? Is this door used more than the other entryways to your home?

Thanks for your comment, user_xq8rih. I'm sorry to hear you're experiencing a similar issue. I'd be happy to help troubleshoot. Can you let us know whether the sensor is showing as open all the time, closed all the time, or if it's not reporting any status changes at all when the door is opened and closed? Also, have you noticed any low-battery alerts for the sensor, or have there been any recent changes near the door that may have affected the sensor's alignment?
