Car Key Simulator is an Android app developed by Wolfie Apps that allows you to prank your friends by simulating a car key. The app is available in the Games category and is licensed as a full version.

The app comes with several features that make the prank realistic. You can make car alarm sounds and pretend to unlock a real car with the app when using it with the real car key (hidden). When you press a button on the car key, the LED light changes from green to red to signal that the car key is working and it emits radio waves. The app also comes with vibrations and screen shake effects that can be turned off if desired.

You can share the app with your friends via e-mail, SMS, Twitter, or Facebook. You can also keep your finger on the button to hear the alarm sound continuously. The app contains advertisements to allow the developer to continue creating fun apps for you.

Please note that this app is only for entertainment purposes, and you should not use it to actually try to unlock a car. If you have any questions or suggestions, you can contact the developer via e-mail.
