How Do You Reset a Ring Contact Sensor?

Ring contact sensors are components of the Ring Alarm system, designed to alert the owner when doors or windows are opened or tampered with. Over time, you may experience technical difficulties or simply need to reconnect the sensor to a new device. In such cases, resetting the Ring contact sensor is a necessary step to ensure its proper functionality.

Resetting a Ring contact sensor differs depending on whether you have a first or second-generation model.

  • For the second-generation sensors, the process involves removing the cover, pressing and holding the reset button with the pinhole tool provided, or a paperclip.
  • The first-generation contact sensor follows a similar procedure, but may require holding the button for at least 10 seconds until the LED light turns red, indicating a successful reset.

Resetting the Ring Contact Sensor

In this section, we will discuss the process of resetting a Ring Contact Sensor, including factory reset, removal, and re-adding the device to your Ring system.

Factory Reset

To factory reset your Ring Contact Sensor (2nd Gen), follow these steps:

  1. Remove the cover of your Ring Contact Sensor.
  2. Press and hold the Reset button inside the contact sensor using the pinhole tool provided in the package or a paperclip.
  3. Hold the button for at least 10 seconds until the LED light turns red, indicating that the device has reset.

Note: For first generation Ring contact sensors, the process is almost identical. Just hold the button until the LED light turns red.

Troubleshooting Sensor Connectivity Issues


If your Ring Contact Sensor appears offline, try to reconnect it to the Ring app:

  1. Disarm your Ring Alarm System using the keypad and your User Code.
  2. Open the Ring app and click on the Menu icon.
  3. Choose Set Up a Device, then click on Security Devices.

If the sensor remains offline, you may need to perform a factory reset:

  1. Remove the cover of your Ring Contact Sensor.
  2. Using the pinhole tool or a paperclip, press and hold the Reset button.

Sensor Connection Issues

Connection issues may arise from interference or obstacles between the Contact Sensor and the Base Station. Ensure there are no thick walls, metal objects, or other devices that may cause interference in the communication path. You may need to rearrange the placement of your Contact Sensor and Base Station to maintain a strong connection.

Range Extender

A Range Extender can be utilized to improve the signal strength between the Contact Sensor and the Base Station. It amplifies the Z-Wave signal to help maintain a strong connection between the two devices while expanding the coverage area. To set up a Range Extender, follow these steps:

  1. Plug the Range Extender into a wall outlet.
  2. Add the Range Extender to your Ring Alarm system using the Ring app.
  3. Allow the Range Extender to connect and configure itself with the Contact Sensor and Base Station.

Z-Wave Technology

Z-Wave technology is a wireless communication protocol used by Ring Contact Sensors and other home automation devices to communicate with each other. Ensure that other Z-Wave devices nearby do not cause interference with the Contact Sensor’s connectivity. You may need to reduce the number of Z-Wave devices within close proximity, or move the Contact Sensor closer to the Base Station to establish a stable connection.

Battery and LED Indicator


The Ring Contact Sensor comes with a battery pre-installed. These batteries typically last for a long time, up to 2 years or more, depending on usage. However, if you notice a decrease in performance, it may be time to replace the battery. In some cases, the battery might need replacement due to low power or other issues.


When it’s time to replace the battery for your Ring Contact Sensor, make sure to use the correct type. The 2nd Generation Ring Contact Sensor uses a CR2032 battery, which is easily available in most stores or online. Remember to dispose of the used batteries properly according to local regulations.

LED Light

The Ring Contact Sensor features an LED light that helps you understand its status. The LED light indicates various states of the sensor, like opening or closing of doors and windows, disconnections, and successful connections. Additionally, the Contact Sensor will flash during the pairing process, indicating that it’s successfully connected to your Ring Alarm System.

Red Light

A red light on your Ring Contact Sensor may indicate a low battery or a connection issue. If the battery light shows a red color, it means the battery is running very low and requires replacement. Furthermore, a red light might also appear if there’s a disconnection or issue with the sensor’s communication with the Base Station. In such cases, it’s essential to check the Contact Sensor’s installation and ensure it’s within the range of the Base Station.

About Ring Contact Sensors


A sensor is a device that detects events, changes in the environment, or external stimuli and provides notifications or simple data output. Sensors perform a key role in various security measures, such as intrusion detection and alarm systems.

Contact Sensor

Contact sensors, also known as door sensors, window sensors, or magnetic sensors, detect the opening and closing of doors, windows, or other openings. They consist of two parts, a magnet and a sensor, which communicate wirelessly. When the two parts are separated, the alarm is triggered.

Ring Contact Sensor

Ring Contact Sensor is a component of Ring Alarm, a popular smart home security system. It helps monitor the opening and closing of doors, windows, or other entryways in a home or office.
