There are a few reasons why your keypad door lock may not be working:

One of the most common reasons why keypad door locks stop working is because the batteries are low. If your keypad door lock uses batteries, be sure to check them regularly and replace them as needed. Usually, keypad door locks will have a low battery indicator that will let you know when it’s time to replace the batteries. 

Most keypad door locks use four AA or AAA alkaline batteries, so you should be able to find them at your local grocery store.

To replace the batteries, open the door and look for the battery compartment. Once you’ve found it, replace the old batteries with more recent ones. In case these steps don’t work, let’s perform another troubleshooting step.

2. Misaligned keypad 

You may have an issue with your keypad not aligning with the deadbolt if it’s not working. This usually happens when you install the lock yourself and don’t align the keypad properly.

Look at the back of the keypad when you open the door to fix this. There should be two screws that you can loosen to adjust the keypad. Once you’ve loosened the screws, try operating the keypad again to see if it works.

3. Dirty or wet keypad 

Occasionally, the keypad is unresponsive or not working properly because dirt and water can disrupt the electrical connections. In such a case, you’ll need to clean the keypad with a dry cloth or compressed air before trying to use it again.

To clean the keypad, use a soft cloth and some rubbing alcohol. Gently wipe down the keypad until it’s clean. Then try operating the lock again to see if it works.

4. Defective keypad 

Although it’s not common, there are times when the keypad itself is defective. You can replace the keypad by yourself if it is defective. However, if you’re not comfortable replacing the keypad yourself, you can always contact a locksmith to do it for you.

Step 1: Open the door and look at the back of the keypad. You will see a small hole with a tiny screw in the center.

Step 2: Tighten the screw using a Phillips screwdriver.

Step 3: Close the door and test the lock. It should work now.

The good news is that it’s not difficult to fix. Simply follow these steps:

Step 1: Remove the batteries from the keypad door lock.

Step 2: Use a Phillips screwdriver to remove the screws from the backplate.

Step 3: Take out the circuit board and examine it for any visible damage.

Step 4: If the circuit board is damaged, you will need to replace it. You can do this by contacting the manufacturer of your keypad door lock.

If the keypad on your door lock is unresponsive, it may be because it’s frozen. This usually happens in cold weather when the moisture in the air condenses and freezes on the keypad.

To get rid of the frozen keypads, you can use a hairdryer to melt the ice. Once the ice is melted, wipe the keypad with a dry cloth to remove any moisture.

Some keypad door locks come with a deadlock mode that disables the keypad when it’s not being used for a certain period. This is usually done to conserve battery power.

If your keypad door lock is in deadlock mode, you’ll need to enter a code to activate it. Once the keypad is activated, you should be able to use it as normal.

This usually happens when the sensors get dirty or there’s debris build-up. To resolve it, simply remove any objects that may be blocking the sensor and try again. You can also clean the sensors with a dry cloth or compressed air. 

12. Faulty Battery Compartment 

The battery compartment of your keypad door lock may be damaged if it is not working. Battery damage usually occurs when batteries are not inserted properly or the compartment is damaged.

Identify the battery compartment by opening the door. Try putting the batteries back in if this does not work. If everything else fails, you may always hire a locksmith to do it for you.
