SimpliSafe Smart Lock Won’t Unlock

If you are having issues unlocking your SimpliSafe Smart Lock, below are a few possible causes:

The SimpliSafe Smart Lock is far from the Base station.

When your SimpliSafe Smart Lock is far from your base station, it could lead to your Smart Lock not unlocking. 

Simply reducing the distance between the base station and the smart Lock or bringing them closer together can solve this issue.

Moreover,  physical barriers or other wireless devices may contribute to the issue. To address this, relocate the Base Station away from solid objects and temporarily deactivate any wireless devices causing interference.

Low Batteries 

If your SimpliSafe door lock won’t unlock, the problem might be that the batteries are weak. 

You will be promptly notified when your SimpliSafe Smart Lock batteries run low. If you already receive notifications through your SimpliSafe system on your smartphone or email, expect alerts regarding the low battery status through push notifications, emails, and text messages.

Furthermore, a slow blinking light on the Smart Lock and a message on your Keypad will indicate a low battery status under your alerts.

The Smart Lock is powered by four (4) AA Alkaline batteries, and the PIN Pad uses two (2) CR2450 Lithium Batteries. These batteries typically last between 8 to 12 months, depending on usage.

To change the batteries in your Smart Lock, follow these simple steps:

  1. Slide down the battery cover (located on the oval portion labeled “SimpliSafe”) to expose the batteries.
  2. Replace the old batteries with new ones.
  3. After replacing the batteries, slide the battery cover back up until it clicks into place.

Poor wifi connection 

Check your wifi strength to see if your SimpliSafe door lock still isn’t responding. 

A poor wifi signal can disrupt communication between the lock sensor and the base station, causing response issues. To tackle this, position your wifi router close to the base station, guaranteeing a smooth connection. 

With a good wifi setup, your SimpliSafe door lock should respond promptly to your every command.

Incomplete SimpliSafe Installation

Another reason your SimpliSafe Smart Lock isn’t unlocking is because you probably haven’t completed installation. This means specific steps in setting up your SimpliSafe Smart Lock haven’t been followed or completed. 

This might include pairing the Lock with the system, configuring access codes, or ensuring proper alignment and Calibration. The smart Lock might not function correctly without completing these steps, leading to issues like failure to unlock.

 Below is a step-by-step guide to wrap up the installation:

  1. Press the Menu button on the smart lock keypad and enter your Master PIN.
  2. Scroll to “Devices” using the right rocker on the Keypad.
  3. Select the device you want to delete by navigating with the right rocker or right arrow on the Keypad.
  4. Then, Scroll down to the bottom of the menu list and choose “Remove.”
  5. Press the off button to return to the Menu.
  6. After completing these steps, use your smart Lock to confirm that the SimpliSafe smart lock not responding error has been successfully resolved.

By completing the installation process, your SimpliSafe smart lock should respond promptly. 

SimpliSafe Door Lock Won’t Lock

The possible reasons your SimpliSafe Door Lock won’t unlock are the same reasons your door lock wouldn’t. Some of these reasons include:

  • The Lock is too far away from the base station
  • Low or drained batteries
  • Poor wifi connection or no internet access
  • Incomplete or improper lock installation

To solve these issues, follow the solutions and instructions in the “SimpliSafe Smart Lock Won’t Unlock” section above.

SimpliSafe Door Lock Pin Pad is Not Working

If your SimpliSafe Door Lock Pin Pad isn’t working, below are several reasons for this and how to fix it. 

  • Low batteries 

Your pin pad is probably not working because the batteries are low or depleted. 

A low battery affects your Lock pin pad because it relies on sufficient power to function correctly. When the battery level is low, the pin pad may not have enough energy to process your commands, leading to unresponsiveness.

Check them to see if they need replacement to ensure proper functionality.

  • Incorrect Pin Code:

 If you enter the wrong pin code, the lock pin pad will not recognize it as the correct authorization, preventing the desired action from being executed.

To resolve this issue, enter the correct PIN associated with your smart Lock to enable proper functioning.

Also, a PIN code entered incorrectly multiple times might lock the system.

  • Signal Interference:

Interference or a weak signal between the door lock and the SimpliSafe base station can lead to communication issues. To solve this issue, ensure the door lock is closer to your SimpliSafe base station 

  • Defective Hardware:

Sometimes, the pin pad or door Lock may have a hardware issue. Contacting SimpliSafe support can help diagnose and address any defective components.

SimpliSafe Warning Smart Lock Not Responding

If you encounter the “Smart Lock not responding” warning problem,  here are possible reasons and solutions:

  • The range between your Smart Lock and Base station :

They might struggle to connect if the Smart Lock is too far from the Base Station. Move the Base Station closer to reduce the distance.

Physical obstacles or wireless devices could also be the cause. Move the Base Station away from dense objects and deactivate wireless devices that are causing interference.

  • Your batteries need replacement:

Check to see if the batteries are weak; they may need replacement 

  • Your Lock may be Obstructed.

Check your door to see if something obstructs it from smoother locking and unlocking.

  • Your Smart Lock needs Recalibration

The Smart Lock’s accuracy might be affected; it only needs Calibration. You can Calibrate it using the steps outlined below. 

  • Press your Keypad’s Menu button and Input your Primary PIN.
  • Use the rocker to access the Devices menu and Choose “Lock” from the Menu.
  • Toggle and select “Recalibrate.”
  • Follow the Keypad prompt to manually turn the Lock to a locked position when prompted to “Close your Door” and press “Done.”
  • The Smart Lock will automatically turn three times during Calibration.
  • If the Calibration is successful, the Keypad will ask, “Check your Door. Is it Unlocked?” Select YES if the door is unlocked.
  • The Keypad will show “Congratulations.” Press OK to exit the calibration process.
  • Firmware Update:

Your Smart Lock may not respond because you use an outdated firmware version. If you are notified of a firmware update on your Keypad, install it as soon as possible to get your Smart Lock responding. 

SimpliSafe Smart Lock Jammed

If your SimpliSafe Smart Lock is jammed, the issue might be that it was miscalibrated. To fix the problem, you just have to recalibrate the Lock. 

Follow these steps to recalibrate using the Keypad:

  • Press the Keypad’s Menu button and Input your Primary PIN.
  • Access the Devices menu and Choose “Lock“.
  • Select “Recalibrate.”
  • Follow the Keypad prompt to manually turn the Lock to a locked position when prompted to “Close your Door” and press “Done.”
  • The Smart Lock will automatically turn three times during Calibration.
  • If the Calibration is successful, the Keypad will ask, “Check your Door. Is it Unlocked?” Select YES if the door is unlocked.
  • The Keypad will show “Congratulations.” Press OK to exit the calibration process.

Suppose your SimpliSafe Smart Lock is still jammed after Recalibration. In that case, you may need to contact customer support, as there may be some serious internal issues. 

SimpliSafe Smart Lock Won’t Connect after battery change. 

If your SimpliSafe Smart Lock doesn’t connect after a battery change, you should reset your SimpliSafe.

Here is how to do that. 

  • Unplug the base station.
  •  Use a screwdriver to open the battery cover at the bottom.
  • Take out one battery and wait 10–15 seconds.
  • Put the battery back and close the cover.
  •  Plug in the base station and wait for a minute or two.
  • Then, arm your system to check if it’s connecting now. 

SimpliSafe Smart Lock Won’t Connect

If your SimpliSafe smart lock is struggling to connect, consider the following: 

  • Wifi Connection: 

Confirm that the Lock is paired with your home’s wifi.

To do that, Open the SimpliSafe app (Android or iOS), tap “My Home,” and check the Lock’s status under “Lock” in the panel. Ensure it’s connected.

  • Keypad Batteries

Check your Keypad’s batteries. If it’s unresponsive, low batteries might be the issue. Replace them with fresh ones and retest.

  • Power Light Verification:

If the power light on your Lock is off, unplug it and plug the batteries back in to ensure they are receiving power.

  • Loose Wires

Check the device for any loose wires or connections. If found, use pliers or a screwdriver to tighten them securely.

If issues persist, contact SimpliSafe Support for further assistance.

SimpliSafe Smart Lock Not Calibrating

If your SimpliSafe Smart Lock isn’t calibrating, here are a few reasons why: 

  • Low Batteries

When the batteries are running low, your Lock might not function well during Calibration because low battery levels can affect how the lock moves.

  To check the battery: 

  1.  Open the front cover and press the Test button.
  2.  If the center light blinks slowly, your smart Lock’s battery is low. 
  3. Replace it right away and try calibrating it again.
  • You may be holding the Keypad far from the Smart Lock. 

This is another reason your SimpliSafe Smart Lock may not be calibrating. To ensure Calibration works, keep the main Keypad close to the Lock.

 Hold the Keypad next to the Lock for the best results while doing the Calibration.

 This proximity helps establish a strong connection between the main Keypad and the Lock, ensuring accurate calibration results.

  • Your Lock is obstructed. 

When something blocks the Smart Lock, it can’t determine its correct position during Calibration. The calibration process needs the Lock to move smoothly, and if there’s something in the way, like a door or frame, it can’t do that properly. So, removing any blockages helps the Lock find its proper position.

 Use a drill or something sharp to make the hole a little bigger. This helps the smart Lock move more quickly.

If the Lock is sticky because of dirt or rust, spraying WD40 can clean it up. This makes the Lock’s mechanisms work much smoother.

However, if the old Lock is too worn out, consider getting a new locking part for your smart Lock. This could solve the problem and make your smart lock work.

  • Outdated SimpliSafe Firmware 

You should check for software updates if your SimpliSafe Smart Lock isn’t calibrating. 

When the firmware is outdated, it may not have the latest instructions or improvements needed for accurate Calibration. 

Therefore, keeping the firmware current is crucial for accurate calibration results.

Before you check for firmware updates, ensure your smart hub is connected to wifi to download the latest updates and that your devices have enough battery power. 

Then, you might notice a gear icon on the Keypad, signaling a software update. Click it and follow the prompts to update your hub’s software.

Once that’s done, check for a firmware update for the hub. Open the SimpliSafe app near the Lock, and it should let you know if there’s a firmware update for the Smart Lock. If there is, follow the prompts to install the latest firmware.

SimpliSafe Change Door Lock Code

To change your SimpliSafe door lock code, follow these simple steps:

  • First, access the SimpliSafe system through the Keypad or mobile app, 
  •  Enter your current PIN code to access system settings.
  •  Navigate to the section related to door lock settings.
  •  Follow on-screen instructions to change the pin code.
  • Then,  Confirm the changes to set the new door lock code. 

SimpliSafe Smart Lock Blinking White

If your smart Lock keeps blinking, here are some things you should consider:

  •  Battery Check

Firstly, check the battery. If there’s a slow blinking light, it could mean the batteries in your Smart Lock are bad and need replacement. 

  • Wifi Connection

If your SimpliSafe Smart Lock blinks white, it could also mean your device has lost the connection. 

Reconnect and make sure there’s no interference from nearby devices. 

  • Check for Updates

 If the issue persists, check for and install any pending updates using the App Store or Google Play Store app on your mobile device.

If problems persist, consider a factory reset as a last resort 

To perform a factory reset, press and hold the reset button on your Smart Lock for at least 10 seconds. This action will reset the Lock to its default settings.
