Ring Alarm
Contact Sensor (Gen 2) stuck on open
Hi, my contact sensor is stuck on open. It all started with the sensor triggering my alarm while it was armed. I thought my home was being broken into, police were also dispatched. Upon inspection nothing was physically wrong with the window or the sensor and my window was closed. I looked online to see if I could find any solution and followed multiple steps to remove the device, factory reset, and add it back to my base but it continues to say the window is “open”. I even tried replacing the batteries to no avail. Yesterday the sensor kept toggling between open and closed and freaked me out when I heard my base chirping like crazy. For some background info, this particular sensor is located toward the back of my home but I have a range extender. There are also multiple sensors located in the same area that have not given me this problem. The sensor is a little over a year old now. Any help or suggests is much appreciated.

My outdoor contact sensor also stopped registering if the gate it was attached to was opened or closed, and just constantly showed in "open" status in my Ring app. It worked fine for just over a year (of course the warranty is only for a year, but the batteries are rated to last up to 5 years, go figure) If I took the main sensor with the batteries off it's mount on the gate, the app would change the status and now indicate the sensor is in a "Tampered" state, which told me that the sensor was still communicating with the base station. Since the ring sensors work together with their respective magnetic "triggers," to function, I surmised that the "switch" inside the sensor (part with the batteries) itself was faulty. I held the sensor and pushed the tamper button so the app would show the sensor was no longer in Tamper status, and put the magnetic trigger right against the sensor and nothing happened, the app still showed the sensor in open status. SO, I got a small round magnet I had laying around from another project and placed it right against the sensor and slid it up and down and sure enough the app suddenly would indicate the change from open to closed state, depending on where the magnet was placed on the sensor. So I held the sensor next to my ear and slid the magnet around on it until I could hear a faint click inside the sensor which was the internal switch inside the sensor being activated and thus triggering the app to change status from open to closed. So the problem is that the magnetic "trigger" that the sensor comes with is no longer strong enough to activate the switch inside the sensor itself. The small round magnet only worked when I placed it right next to the sensor itself and that was impractical since the magnet would HAVE to be attached to the magnetic trigger itself to work. So I found a larger more powerful magnet, which I had removed from an old computer disk hard drive and stuck it to the magnetic trigger, which since they are BOTH magnets, they will stick together as long as you don't have the poles reversed! Speaking of which, the magnet will NOT stick to the very center of the magnetic trigger, it will attach just off center, but that's fine because if placed directly in the center, it won't activate the switch in the sensor. So with the stronger magnet now stuck to the trigger magnet, I attached both the trigger and sensor back on their original mounts on the gate, and the sensor now works just as before. SO, just buy some cheap strong magnets from Amazon or local big box hardware store and experiment with where you place them, which will be off center, on the trigger magnet, stack them on top of each other if needed to increase magnetic strength, or ask one your younger family members to give you an old hard drive magnet that one of them is sure to have or can get their hands on, and problem solved!

Hi @Jvysun. You've covered most of the typical troubleshooting steps I would have suggested for this situation. One more thing I would suggest is taking a different Contact Sensor and putting it on the same window this Sensor is on. If the new Contact Sensor doesn't exhibit the same issues, then it would be isolated to the original Sensor. If that's the case, please give our support team a call at one of the numbers available [here](https://support.ring.com/hc/en-us/articles/213608406) so they can determine the best resolution.
