How to Change Existing Names in "The Sims 2"by Contributing WriterUpdated September 22, 2017
With Sims 2, it's annoying to realize you've made a typo in the entry box. Or, you may decide the name you've chosen for your Sim was a bad choice. Particularly for first names, it can be a pain. You can change existing names in the program. After all, a name is all your Sims have.
Go to the the main neighborhood screen. Press Control, Shift and "c" simultaneously. A text box should appear in the upper left-hand corner.
Type "BoolProp Testingcheatsenabled true" into the box (without quotation marks) and press Enter.
Select the lot where the Sim whose name you would like to change lives. Once the game is in play, click on the Sim while pressing shift. Make sure this is the active Sim by noting the box around his picture on the left.
Look for the option "spawn" from the listed items, and click. Afterward, click on "Tombstone of L&D." A tombstone should then appear.
Click on the tombstone and press "rename sim," and type in the new name. To bring the game back to normal, as in take off the cheat mode, re-enter the cheat code in Step 2 but with "false" in place of "true."
Be sure to enter the "BoolProp..." cheat correctly as it is case-sensitive. If it does not immediately work, lowercase the "p" and try again.
Use caution while using cheats, as these can potentially damage the game if used very frequently.
