Explanation:

A major victory was won by the Akalis in the Keys Affair’ in October 1921. The Government made an effort to keep possession of the keys of the Toshakhana of the Golden Temple.The Akalis immediately reacted, and organized massive protest meetings; tens of Akali jathas reached Amritsar immediately. The SGPC advised Sikhs to join the hartal on the day of the arrival of the Prince of Wales in India. The Government retaliated by arresting the prominent, militant nationalist leaders of the SGPC like Baba Kharak Singh and Master Tara Singh. But, instead of
dying down, the movement began to spread to the remotest rural areas and the army. The Non-Cooperation Movement was at its height in the rest of the country. The Government once again decided not to confront Sikhs on a religious issue. It released all those arrested in the ‘Keys Affair’ and surrendered the keys of the Toshakhana to Baba Kharak Singh, head of the SGPC in 1921.
