The double honk horn sound is activated whenever you close the door of your vehicle while the engine is still running. Some drivers find this annoying so they disable this feature on their vehicle. 

The Keyless Entry feature, on the other hand, allows drivers to enter their vehicles without using any key for as long as they carry their keyfobs with them. The built-in system automatically detects that the keyfob is within range and it will unlock the vehicle as soon as the front door handle is pulled. 

These two features can be unlocked using FORScan. Here's a list of the known Ford As-Built data modifications on Double Honk and Keyless Entry functions that you can unlock with FORScan:
