Prince Andrew reportedly got into a scrape after his Range Rover was damaged in his attempt to get through the gates to his Windsor home and avoid a 1.5km detour.
When the automatic sensors did not work, he tried to force the gates open by ramming the £80,000 ($168,230) vehicle into them, according to The Sun.
The metal gates guard the entrance to Windsor Great Park, where the 56-year-old lives in the Royal Lodge, the former residence of the Queen Mother. He was given the Lodge by the Queen in 2003.
The park is said to have been left with a bill running into the thousands to repair the damage.
Buckingham Palace declined to comment on the incident, and refused to say who would have to pay for the repairs to the car and gate.
