Lubricate The Lock

Try lubricating the lock cylinder with a graphite-based lubricant or a silicone spray. Here’s how,

  • Step 1: First, gather your materials. You’ll need a can of lubricant spray and a small nozzle attachment for the can.
  • Step 2: Now spray a small amount of lubricant into the keyhole, aiming the nozzle towards the lock mechanism.
  • Step 3: After that, insert the key into the lock and turn it back and forth several times to distribute the lubricant throughout the lock mechanism.
  • Step 4: Next, use a rag or paper towel to wipe away any excess lubricant from the lock and surrounding areas.
  • Step 5: Finally, turn the key several times to make sure that the lock is working smoothly.

Replace The Key If It Is Worn Out

Check the key for any signs of damage, such as bent or missing teeth. If the key is damaged, you may need to have the key replaced.

If you have a warranty or need assistance with a Defiant lock, you can contact the company’s customer service department. They may be able to help you get a replacement key

Otherwise, many hardware stores have key-cutting services, so you can bring your lock to the store and have a new key made on the spot. Make sure to bring identification and proof of ownership of the lock.

Use A Lubricant To Loosen Any Debris Or Rust 

If the lock is still sticking after adjusting the latch, it might be because debris or rust has built up inside the mechanism. To fix this issue, you can use a lubricant to loosen the debris and help the mechanism work smoothly. Follow these steps:

  • Step 1: Apply a lubricant spray to the latch and bolt mechanism of the lock.
  • Step 2: Turn the key several times to distribute the lubricant evenly throughout the mechanism.
  • Step 3: If any excess lubricant exists, wipe it away with a cloth or paper towel.

Check If The Lock Is Properly Installed

If your Defiant electronic lock keypad is not working, the first thing you should check is whether it is properly installed and receiving power. Here are some steps to take:

Ensure that the wires are properly connected: Check that the wires are properly connected to the lock and that they are not loose or disconnected. Make sure that the wires are connected to the correct terminals on the lock.

Check the power source: Check that the lock is receiving power from the correct power source. If the lock is battery-operated, ensure that the batteries are fully charged and properly installed. If the lock is wired to an electrical source, check that the power supply is working correctly and that the lock is receiving power.

Replace The Defiant Lock Batteries

Most Defiant electronic locks typically require four AA alkaline batteries. However, the exact number of batteries required may vary depending on the specific model of the lock. It’s always important to check the lock’s manual or the label on the battery compartment to confirm the number and type of batteries required.

To replace the batteries in a Defiant lock, follow these steps:

  • Step 1: Locate the battery compartment. It is usually located on the back of the lock, near the bottom.
  • Step 2: Remove the battery cover by sliding it using your thumb or a screwdriver.
  • Step 3: Now remove the old batteries from the battery compartment.
  • Step 4: Insert fresh batteries into the battery compartment, making sure that they are inserted in the correct direction. The correct battery type and orientation should be indicated on the battery cover or the battery compartment.

Issue 4: Defiant Programming Code Not Working

Issue 4: Defiant Programming Code Not Working


The programming code for Defiant locks is a combination of numbers that is used to set up the lock and change its settings. The programming code is usually set by the lock owner during the initial setup process and can be changed later on if desired. 

Follow the given troubleshoots if your Defiant lock programming code is not working.

Ensure Entering The Correct Programming Code

When programming your Defiant lock, it’s important to ensure that you are entering the correct programming code. To do this, you should double-check the manual that came with your lock to ensure that you are entering the right code. Sometimes, programming codes may differ depending on the model or version of your lock. If you don’t have the manual, you can usually find it online by searching for the model number of your lock.

Ensure That The Lock Is In Programming Mode

Defiant locks have a programming button located on the inside of the lock to enter programming mode. This button is usually labeled “prog” or “program” and may be located on the back or bottom of the lock. Failure to enter the programming mode correctly may result in the programming code not working.

Check The Battery Level

Low battery levels can cause issues with the programming and operation of your Defiant lock. Therefore, it’s important to check the battery level and replace the batteries with fresh ones if needed. You can usually tell when the batteries are low because the lock will start to beep or flash a light.

Reset Your Defiant Lock

If all else fails, you can try resetting the lock to its default settings. Performing a factory reset will erase all existing codes and return the lock to its default settings. Once you have performed a factory reset, you can try programming the lock again. 

Here are the steps to reset your Defiant lock.

  • Step 1: Remove the battery pack from the back of the lock.
  • Step 2: Wait for a few minutes to allow the lock to power down completely.
  • Step 3: Reinsert the battery pack back into the lock. Ensure that the batteries are inserted in the correct orientation.
  • Step 4: Enter the lock’s default code, which is usually found in the lock’s manual or on the packaging.

Connect Both The Lock And Smartphone To The Same WiFi

To control your lock with a smartphone app, you need to ensure that your smartphone is connected to the same Wi-Fi network as the lock. If your lock is connected to a different network, it won’t be able to communicate with the app. 

Check If The Defiant Connect App Is Updated

Smartphone apps are frequently updated to fix bugs and add new features. If your app is outdated, it may not work properly with your lock. To update the app, go to the app store (Google Play or App Store) and search for the app. If an update is available, click the update button to download and install it.

Reset The Defiant Lock

If none of the above steps work, you can try resetting your lock to its default settings . Resetting your lock will erase all existing codes and return the lock to its original settings. 

To reset your lock, as mentioned in the previous section, remove the batteries and wait for a few minutes before inserting them back. Once inserted, enter the default programming code mentioned in the user manual.

  1. When I lock my door from the outside
    I cannot unlock it. The keypad won’t even light up to type in code. Instead it keeps locking.
    It’s brand new. If the door is open I can wave my hand over it and the dead bolt comes out. I can then enter the code and the dead bolt unlocks. But if I close the door and wave my hand to lock it I cannot unlock it since the keypad won’t come on.

    If I lock it from the inside – someone on the outside can successfully use the keypad to unlock the door.

    Safe at night. Locked out when when I come home from work
