Keypads stopped working (1st Gen)

Recently, our keypads have required multiple entries for the base station to accept the code. It seemed to be getting worse over time. Today, we tried muliple times to enter the code and finally used the app to turn off the alarm. Also, the red connection light was on both keypads. One of the keypads is about 6 feet from the base station. After that, I couldn't get the keypad to arm or disarm the alarm, the red light was on. I called support and we went through quite a few troubleshooting steps including removing the keypad from the zwave network. Then we couldn't get the keypad reconnected. We then moved the base station to another room and the keypad connected. I was only able to get it to arm once and now it's in the same state. Both keypads work occasionally, but only after many tries and the red connection light displays. I've tried moving the base station to every room in the house along with the keypads without success. It was working great for 10 months and recently started to degrade. Is this an issue with the keypads?
