The process of changing the code for a smart lock may vary depending on the manufacturer and model of the lock, but generally the steps are similar. Here is a general guideline for changing the code for a smart lock:

1.Identify the type of smart lock you have and determine the instructions for changing the code. This information can usually be found in the user manual or on the manufacturer's website.

2.Access the smart lock control panel or keypad by inputting the current code or using the mobile app.

3.Look for the option to change the code or reset the lock.

4.Follow the prompts to enter the new code. Some smart locks require you to enter the old code first before entering the new one.

5.Once the new code has been entered, test the lock to ensure it is working properly with the new code.

6.If you encounter any issues or errors during the process, refer to the user manual or contact the manufacturer's customer support for assistance.

Remember to keep your new code secure and do not share it with unauthorized persons. Changing your code regularly can also help improve the security of your smart lock system.
