In Rogue One, prior to the Battle of Scarif, the Rebel infiltration unit led by Jyn Erso used a stolen cargo shuttle to land on the planet. K-2SO assumed the clearance code of the shuttle might have been logged as overdue by the Empire, but nevertheless the team decided to proceed.
Bodhi: Cargo shuttle SW-0608 requesting a landing pad.
Gate Officer: Cargo shuttle SW-0608, you're not listed on the arrival schedule.
Bodhi: Acknowledged, Gate Control. We were rerouted from Eadu flight station. Transmitting clearance code now.
Here, during the following short period of silence, Jyn revealed the Kyber crystal necklace she had gotten from her mother, held to it, closed her eyes, and apparently meditated for a moment. Then, the gate officer let the ship pass the shield gate.
Gate Officer: Cargo shuttle, SW-0608, you are cleared for entry.
Did Jyn use the Force to manipulate the gate officer to let them pass through? Did she use the necklace somehow as a link to the Force? Could she have done it without the crystal?
Interestingly, when the necklace was given to Jyn by her mother, she said:
Lyra: Trust the Force.
...Or was the access code just valid?
