The whole method is a shift from manual locking to the digital locking mechanism. For this, a lock mechanism, comprising of a digital keypad of numbers (sometimes alphabets and symbols also, depending upon the model) is used.

The system has batteries installed in it. These batteries are installed inside the case that lasts for enough long time. These batteries are used to provide the small supply of current to lock and unlock the bolt/latch in the door frame. The conduction of current (to open the bolt) is only possible when the correct code is entered. Thus, a wrong code: no conduction: no unlocking.

For added security, the option of changing the security code is also in the locks. This is a guide to tell you how to change code on an electronic door lock.

Step by step guide : how to change code on electronic door lock


First, you have to remove the lock from the door. Removing the lock means: you have to unscrew the whole lock apparatus from the door. The removing method is described in detail, in the manuals. You can refer to that, for more help in this.


The lock has two faces. One that has a keypad and the other that was attached to the door. You have to turn over the lock so that the back face is towards you (or the keypad face is downward). You will find some screws at the back of the lock apparatus. Use a screwdriver to unscrew those. There will be two: one at top and one at the bottom, or maybe one. Move the screwdriver anti-clockwise and remove the screws.


After unscrewing, you have to remove the backplate of your lock. The backplate comes out when you remove the screws. After removing the plate you will see different holes that are colored differently. They would be either in blue or in red color. Keep in mind that the red holes are coinciding with the conduction-code combination.


Now you have to take out your tweezers and put them inside each red hole. There will be some metal chips inside those holes. You have to remove those metal chips and place them aside, on a table.


You have the new lock code in your mind. You have to remove the blue chips from the holes (that are numbered) and remove them so that, they conform to the new code you are willing to put. You have to replace the blue-chip with red, one by one. The small chips have a short cut of square shape. You have to take care that this square cut is facing towards the outer part of the door lock.


Now, when you are done putting the red chips on your desired code combination. Fill the remaining holes with the blue chips. Also, cross-check if the red chips are precisely according to your code.


Put the cover back on lock and screw it again with the screwdriver.

Final step

The last step is to check your set-up lock code before putting it on the door. For this, you have to press the clear button on the lock front and then put the newly made code into it. It will un-lock it in an instant; after putting the new lock (If the code is correct).

What to do if the lock doesn’t unlock after entering the new lock?

It’s good that you have found this issue in time. You have to unscrew the backplate and confirm if the red chips are precisely placed over your desired combination or not. If not, arrange them accordingly. I hope this guide about how to change code on electronic door lock helps you to resolve this issue.
