What Causes a SimpliSafe Keypad to Not Work?

There are several reasons why your SimpliSafe Keypad might be having issues, some a little more complex than others. The potential causes for a SimpliSafe Keypad not working include the following;

  • Interference or Communication Issues

Your Keypad may be experiencing some interference, hindering communication between the Base Station and the Keypad. Also, some communication problems may arise due to obstacles or changes in the environment.

  • Battery Life

The Keypad usually needs new batteries every eight months. If it’s losing connection, it could be time to replace them as expected.

  • Environmental Changes

Being away for an extended period, having an FM radio, or using doors differently could disrupt communication. Environmental changes, like radio signals or infrequent door use, may also affect SimpliSafe system performance.

  • Thresholds for Communication

Consider reviewing how the system decides if a sensor is well-placed to communicate with the Base Station. Suppose the system is having difficulty recognizing when doors are closed. In that case, the system’s sensitivity settings might need adjustment or improvement.

  • Improper Installation

The Keypad may not even turn on if you didn’t set up everything correctly correctly.

  • Power Interruptions

After a power outage, battery-related issues may arise. Consider replacing the batteries with new ones.

  • Software Hiccups

If the base station’s software recently updated, the Keypad might act up. You’ll need to go through the setup process again.

  • Pairing or Connectivity Problems

Suppose the Keypad is not paired or the connection is lost. In that case, you must re-sync it with the base station to restore proper functionality.

Do note that the actual causes may vary, and professional assistance or further evaluation may be required for an accurate diagnosis.

SimpliSafe Keypad Not Working After Battery Change

If your SimpliSafe Keypad isn’t powering on after a battery change, don’t worry. Here’s a step-by-step guide to help you troubleshoot and resolve the issue.

The system should alert you when the Keypad has low batteries, giving you time to replace them.

Quick Steps for Powering On

  1. Slide the Keypad up and remove the back panel.
  2. Take out all four batteries.
  3. Wait at least 30 seconds to ensure the Keypad fully powers off.
  4. Insert four new AA batteries, preferably less than eight months old.
  5. Ensure correct battery installation with the negative side touching the springs.

Additional Troubleshooting

If the Keypad still doesn’t light up, try using a known pair of working AA batteries (e.g., from a remote control).

If it powers on with these batteries, replace the Keypad batteries with a new set.

But Suppose the Keypad doesn’t respond with known working batteries. In that case, there may be some hardware problem, and you may need to contact our support team for further assistance.
