Defiant Lock Troubleshooting: Problems and How to Fix

Last Updated on May 2, 2024 by Vincent Zhu

Defiant locks are among the best-sold keypad deadbolt door locks in Home Depot. They are popular due to their ease of use and flexibility. However, they can sometimes have some issues. Here are some common problems and solutions if you have a Defiant lock.

In this article, we will discuss Defiant Lock troubleshooting so that you can best diagnose any issues with your locks and get them working again quickly and efficiently!

If your Defiant smart lock is not working, it might be time to troubleshoot the problem. The following are some common Defiant lock problems and their solutions:

The Defiant lock keypad is not working or responding.

Defiant lock Keypad not working or responding

  • If the keypad is not responding to your input, it may be because the batteries in your lock have run out of power. Replace them with fresh ones and see if that helps fix your issue.
  • Does the keypad light up when pressed? If it doesn’t, there may be an issue with the lock’s power supply or wiring. Also, make sure that any wires are securely connected.
  • Make sure the batteries are installed properly.
  • If the battery indicator keeps flashing, the batteries are getting low. Please replace them with four new batteries for the best performance (alkaline batteries only ).
  • Ensure the cable is well-connected to the port and was not damaged during installation.
  • Please ensure the lock has been set up and complete the bolt direction determination.

Defiant lock can not lock/unlock by the keypad.

If you can not lock or unlock your Defiant lock with the keypad, please try the following:

  • Make sure you have entered the correct User Code.
  • The battery is low if the battery indicator light keeps flashing. Please replace them with four new batteries.
  • Make sure the cable is firmly connected.
  • Check the cable for any damage that may have occurred during installation.
  • Make sure the batteries are properly installed. (Alkaline batteries only)
  • Check the strike plate to ensure it is properly aligned and clear so the bolt can freely move in the hole.

The Defiant lock can not be reset.

If the indicator light keeps flashing, please ensure the battery is not low. If it is, please replace it with four new batteries and factory reset it again.

If you’re having trouble getting your Defiant to lock to turn sometimes but not others when you press its buttons:

  • Try cleaning its sensors with rubbing alcohol and a cotton swab; sometimes, dirt buildup can get between them and cause this problem.
  • The lock won’t lock/unlock – If you’re having trouble locking your door after entering a code or using a key, there may be something wrong with either of these components. Try replacing them if necessary; otherwise, check for obstructions in their paths and remove them if possible (for example, doorknobs).
  • Unplug the power cord from the wall and remove the batteries from your keypad. This will prevent any potential damage to your lock as you work on it.
  • Take off all of the screws on each side of your door jambs and lift out both jamb covers so that you can access all sides of your door frame.
  • Use an Allen wrench or screwdriver to remove both strike plates from their holes in your doorframe’s top and bottom corners. Once removed, check for damage, such as loose screws or stripped threads inside of them (which would require replacement).
  • Reinstall new strike plates if necessary before replacing both jamb’s covers onto their hinges; remember not to tighten them too much so they stay secure but not too loose and fall off easily!

The Defiant lock Keeps beeping.

  • If your Defiant lock keeps beeping, the most likely cause is that you’ve used the wrong user code. Now, you can try to change the code on your lock.
  • It’s probably because the battery is low. Try removing and replacing the batteries to see if that solves the problem.
  • The door doesn’t unlock properly.

The Defiant lock is not opening.

If your Defiant lock is not opening, it’s likely because the battery is dead. To fix this problem:

  • Replace the battery: Replace the old batteries with new ones.
  • Reset your device: If you’ve already replaced the batteries but are still having difficulties unlocking your door, try resetting your device by pressing both buttons for 5 seconds until they stop blinking (this will turn off all functions of both devices). Once complete, try unlocking again using either button on either side of both devices.

The Defiant lock can not add a delete user code.

The Defiant lock can not add a delete user codes

  • Please ensure the programming process is completed in 10 seconds; otherwise, the lock will time out.
  • Please ensure the user code in your Defiant lock is not full.
