TEEHO Door Lock Troubleshooting

Are you facing some issues with your TEEHO Door Lock, such as the deadbolt not locking/unlocking? In this post, I’ll guide you through the steps to troubleshoot your TEEHO electronic door lock.

Whether you’re having challenges adding/deleting a User Code, or you lost your Master Code, you can resolve the issues with the steps I’m going to provide here. So, let’s get started.

In short, if you experience any undesirable operation in your TEEHO Door Lock, a quick way to resolve the issue is to replace the batteries. If that doesn’t help, performing a factory reset might do the trick.

Inspect the Batteries

If your TEEHO door lock is not working properly (not locking/unlocking), the first step to take in resolving the issue is to check the batteries.

As you probably know, the lock runs on battery power. If the batteries are not properly placed on the right terminals, or if they are low, your lock may not work.

So, start by checking if the batteries are properly placed. Remove them from the battery pack and insert them back in—ensuring they are placed correctly, following the battery polarity (+/–).

Now check to see if your lock works properly. If not, your battery might be low.

Your TEEHO Door Lock has a low battery indicator (frequent red flashes). If the lock is currently blinking red, the batteries are actually low and need to be replaced.

But in some cases, your batteries might be the cause of the problem, and your lock won’t blink red. This happens when the batteries are bad—not compatible with the lock, or substandard.

So even though you don’t see red flashes to show the batteries are low, replace them with new ones to see if that resolves the problem.

Note that the ideal batteries for the TEEHO electronic door lock are non-rechargeable, alkaline batteries. Do not use lithium batteries and avoid mixing new batteries with old ones.

Perform the Door Handing Detection

If your lock is still not working after inserting the batteries properly or getting new batteries, the next thing you want to do is perform the door handing detection.

The door handing detection process is crucial to the lock’s electronic operation. This process is usually done during installation.

It helps the lock to learn the orientation of the door—whether it’s a right or left-handed swing door. If you fail to perform this process or don’t perform it correctly, you may have issues locking/unlocking the door through user codes.

So, you’ll need to perform the door handing detection to see if it fixes the issue. Here is how to do that:

Open your door and make sure it’s unlocked.
Go to the interior assembly of the lock and open the battery cover. If you already have batteries inside, take them out.
Next, insert three batteries. Make sure you’re only using AA alkaline batteries.
Using a pin or the reset tool that came with your lock, press and hold the reset button. You’ll find the reset button below the battery compartment—labeled RES.
Keep holding the reset button until you hear a long beep. Once you hear the beep, insert the last battery and continue holding the reset button until you hear a long beep and latch bolt extend to learn the orientation of the door.
Now the door handing detection process is complete—and that should resolve the issue.

Is your TEEHO Door Lock still not working properly? Continue to the next step.

Check the Connector Cable

Another reason your TEEHO lock may malfunction is if the cable that connects the exterior assembly to the interior assembly is not tightly connected.

If you’re experiencing keypad issues, it’s most likely because the cable is not properly connected.

To fix this, remove the battery cover from your lock and check that the cable is tightly connected. See the image below.

If the cable checks out and your lock is still not working, continue to the next step.

Perform a Factory Reset

Resetting your TEEHO keypad deadbolt can help resolve several issues, such as keypad not responding, lost Master Pin Code, User Code, etc.

If other fixes couldn’t help, try resetting the lock to see if it helps.

Follow these steps to factory reset your TEEHO Door Lock:

Keep your door open.
Open the battery cover to find the reset button. It’s a black circle button labeled “RES.”
Get a pin or paper clip, or the reset tool that came with the lock. Next, press and hold the reset button using any of the tools mentioned.
While still holding the reset button, remove one battery and put it back in.
Keep holding the reset button (for about 3 seconds) until you hear a beep.
Now your lock is reset, and this should resolve the issue you’re having with the lock.

Note that resetting the lock will remove all user codes and other custom settings in the lock. So, you’ll need to program the lock again.

Wrapping Up

So that’s how to troubleshoot your TEEHO Door Lock. If you’re experiencing programming issues, such as not being able to add or delete a User Pin Code, make sure you’re completing the steps within 10 seconds.

More so, if you’re entering a new user code, do not enter a forward, backward, or repeat number sequence. Use completely different numbers to make a code and make sure it’s not containing an existing code sequence.

I hope this post was able to help you troubleshoot your Teeho electronic lock.
