Only allowed cells to be filled by double clicking for current time and date

Hi,
I am working on creating a file to track in time and out time of employees.
Based on the previous posts here, I am able to write a VBA that will allow the user to double click the cells to show current time and date.
However, I would like to make sure that nobody can cheat their time by change the time manually on the spreadsheet.
Is there any VBA that is able to locked the cells that only the double click features allowed in the cells?

Thank you in advance!!

The attached is as similar project. In this project, the following macro prevents the users from altering their time :

Perhaps by examining this code you can transpose similar to your macro.

Thanks!
I actually have the vba already for double clicking (see below), How can I incorporate the locked with password so that nobody can enter the time manually?

I am unable to enter the time manually in the attached workbook.

If you did it by key entry .. how ?

Logit,
I do not have a lot of experience in VBA.
The one you attached work fine, but I inherited a file that somebody created, hence I would like to incorporate the lock with password option to the existing vba attached above.

Thank you

See the comments to the right of the code lines for Columns K & L. K & L is where the staff will double-click (for this example) to enter their time. The columns can be changed
in the code to any columns you desire. #11 is Col K ... #12 is Col L (counting from the letter A which is #1).

There is a way you can leave these two columns as is (double click only) and password protect all the other columns. Refer to this resource :

Also, for your purposes, the macro code below the above lines of code can be deleted from the project. They don't do anything for your purposes.

Let me know if you need anything else.

This is great! thank you!

You are welcome.

Cheers
