Keyless entry. At least my 2013 does not have that and I do not recall seeing that as an option.
Would love to have just a keyfob in my pocket, walk up to the truck and simply open it without any other input at all.

The ability to shut the door chime off.
Raptor Chime Off
1. Parking brake set
2. Truck in park
3. Ignition switch in off position
4. Both seat belts unbuckled
5. Turn the ignition switch to the on position, DO NOT START THE ENGINE.
6. Wait until the safety belt warning light turns off. (approximately 1 minute).
7. Within 50 seconds buckle then unbuckle the seat belt 9 times, ending in the seat belt unbuckled. The restraint warning light, (airbag light) will turn on for three (3) seconds.
8. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
The restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation
It is reversible by doing the same steps as disabling.
