Defiant Keypad Not Responding:

If your Defiant Electronic Lock keypad suddenly stops responding, or won’t respond after installation, here are some troubleshooting tips to try:

Inspect the Batteries

If the batteries in your Defiant Lock are low or not installed properly, the keypad may not respond. If your lock develops this issue, start your troubleshooting by removing the batteries and putting them back in properly.

When reinstalling the batteries, ensure that the positive end of each battery is placed on the positive part of the terminals.

If the problem persists, the batteries might be low. Usually, your Defiant Lock will flash red consistently if the batteries are low. If you see these red flashes on your lock, get a new set of alkaline batteries and replace the old ones. Ensure you don’t use lithium/rechargeable batteries.

Note that you may not see the low battery warning on the lock if the batteries are faulty or so. So, replace the batteries in your lock even though you don’t get a low battery warning.

Is your Defiant Lock keypad now working after changing the batteries? If not, continue to the next step.

Check that the Cable is Well-Connected

Your Defiant Electronic Deadbolt has a cable that connects the exterior assembly to the interior assembly. If this cable is not connected properly to the port, your lock won’t work electronically.

Remove the battery cover from your lock. Then check to see if the cable is connected to the port firmly. If not, get it connected properly. If the cable is damaged, you may need to replace it.

Complete the Bolt Direction Determination Process

If your Defiant Electronic Deadbolt keypad isn’t responding after installation, chances are you didn’t complete the bolt direction determination process.

The bolt direction determination teaches the lock the orientation of your door (right or left-handed swing), so the keypad may not work if you don’t complete this step.

You can complete the bolt direction determination by resetting the lock and entering the default Master Code.

Here’s how to do this:

Go to the interior assembly of your lock and remove the battery cover. Then take out one battery.
You’ll see a black circle button near the bottom part of the battery compartment. That’s the SET button.
Press and hold the SET button. While still holding the SET button, put the battery back in.
Keep holding the SET button until you hear a long beep and a short beep.
Enter the default Master Code (123456) to complete the bolt direction determination process.

Now, try to operate the lock again to see if it works.

Note that you have to change the default Master Code to ensure security. You should also program new User Codes to be able to lock/unlock your door through the keypad.

Defiant Lock Won’t Lock or Unlock through the Keypad:

If you’re having this issue with your Defiant Electronic Lock, the first thing to do is to check that your User Code is correct. You can’t unlock the deadbolt through the keypad if the User Code you entered is incorrect.

Next, low battery power could also be the reason this is happening. If you’ve verified that you’re entering a correct User Code but the lock won’t unlock, replace the batteries to see if it fixes the problem. Also, ensure the cable is connected to the port firmly.

You may also experience this problem if you didn’t complete the bolt direction determination process after installing the lock. You can complete the bolt direction determination on your Defiant Lock by resetting the lock. See how to do this above.

Unable to Add User Codes or Change Master Code on Your Defiant Lock:

This could be happening because you’re entering an incorrect Master Code. As you probably know, you’ll need to enter the current Master Code of your lock to put the device in programming mode. If you don’t remember your Master Code, reset the lock and reprogram it with the default Master Code (123456).

Another reason for this issue is that you’re not completing the programming process within 10 seconds. The unit will time out if the programming exceeds 10 seconds. So, once you enter your Master Code, ensure that you complete the programming in 10 seconds.

More so, the lock won’t accept a new User Code if the capacity is full. You may need to delete an existing User Code, then try adding a new code again.

If you’re still unable to add/change the Master Code, reset your lock and reprogram it. See how to reset and reprogram your Defiant Electronic Lock.

Wrapping Up

For the most part, replacing the batteries in your Defiant Electronic Lock will help fix several issues (not locking/unlocking) you’re having with the lock

However, you may need to try other fixes like connecting the cable to the port tightly, completing the bolt direction determination process, and resetting the lock.
