Garage Door sensor acting up

After years of use one of my garage doors sensor is not working properly, I though it was just and old battery so I went ahead and replaced the battery but that didn’t fixed it, just yesterday it gave me two false alarms.
I need a Technician to come out here to check and repair or replace the sensor as needed.
Would you be able to help me with this matter?

suretyDIY is a DIY monitoring service. suretyDIY users perform maintenance on their own systems, and we would be happy to assist with remote troubleshooting.

However, it looks like this may be related to an old suretyCAM installed system. I will have our customer service email with information.
