TEEHO Door Lock Troubleshooting (Quick Fixes)

Are you experiencing problems with your TEEHO Door Lock, such as the deadbolt not locking/unlocking? In this tutorial, I will walk you through the process of TEEHO Door Lock Troubleshooting.

Whether you’re having trouble adding or deleting a User Code or you’ve misplaced your Master Code, I will help you fix the problem. So let’s get started.

Quick Tip: if you have any problems with your TEEHO Door Lock, replacing the batteries is a straightforward solution. If it doesn’t work, a factory reset may do the trick.

Continue reading for a thorough guide on the TEEHO Door Lock Troubleshooting process.

TEEHO Door Lock Troubleshooting Steps

1- Battery Inspection

If your TEEHO door lock is not functioning correctly (not locking or unlocking), the first step in repairing the problem is to check the batteries.

As you are presumably aware, the lock operates on battery power. If the batteries are not correctly installed on the correct connections or are low, your lock may not function.

So, start by ensuring that the batteries are correctly positioned. Remove them from the battery pack and re-insert them, making sure they’re polarized appropriately (+/-).

Now check to verify whether your lock is functioning properly. If not, your battery may be low.

Your TEEHO Door Lock displays a low battery signal (frequent red flashes). If the lock is now blinking red, the batteries are running low and should be changed.

However, in rare circumstances, your batteries might be the source of the problem, and your lock will not glow red. This occurs when the batteries are defective, incompatible with the lock, or poor.

So, even if you don’t see red flashes indicating that the batteries are low, change them to see whether the problem is resolved.

It should be noted that non-rechargeable alkaline batteries are best suited for the TEEHO electronic door lock. Avoid using lithium batteries, and don’t combine new and old batteries.

2- Door Handing Detection should be executed.

If your lock is still not working after correctly inserting or replacing the batteries, the next step is to perform door-handling detection.

The door handling detection procedure is critical to the lock’s electrical functionality. This technique is often completed during installation.

It allows the lock to learn whether the door is swinging right or left. If you fail to or incorrectly conduct this operation, you may have trouble locking/unlocking the door using user codes.

So, you’ll need to run the door-handling detection to see if it resolves the problem. Here’s how to do it:

  • Open your door and ensure it is unlocked.
  • Access the lock’s inner component and remove the battery cover. If you already have batteries inside, remove them.
  • Next, insert three batteries. Make sure to only use AA alkaline batteries.
  • Use a pin or the reset tool that came with your lock to push and hold the reset button. The reset button labeled RES is located underneath the battery compartment.
  • Continue pressing the reset button until you hear a lengthy beep. When you hear the beep, insert the final cell and keep pressing the reset button until you hear a lengthy beep and the latch bolt expands to learn the orientation of the door.
  • The door-handling detection procedure is now complete, which should address the issue.

3- Inspect the Connector Cable.

Another reason your TEEHO lock may fail is if the cable connecting the outside assembly to the inner assembly is not securely linked.

If you’re having keypad problems, it’s most likely because the cable isn’t connected properly.

To solve this, remove the battery cover from your lock and ensure that the wire is securely attached.

If the cable checks okay but your lock still does not function, proceed to the next step.

4- Do a factory reset.

Resetting your TEEHO keypad door lock can assist with a variety of difficulties, like the keypad not responding, missing Master Pin Code, User Code, and so on.

If other solutions fail, try resetting the lock to see if it works.

Follow the instructions below to factory reset your TEEHO Door Lock.

  • Keep the door open.
  • Open the battery cover to see the reset button. It is a black circular button labeled “RES.” 
  • Obtain a pin, paperclip, or the reset tool that comes with the lock. Press and hold the reset button using any of the tools indicated above.
  • While still holding the reset button, remove and replace one battery.
  • Hold the reset button for roughly 3 seconds until you hear a beep.
  • Your lock has now been reset, which should alleviate the issue you are experiencing.

It is important to note that resetting the lock would delete any user codes and other custom settings. As a result, you will need to re-program the lock.
