The award came for her involvement in the Haslemere Police Community Partnership.
However, despite being nervous beforehand, Mrs Keen said that she was calm when she spoke to the Queen.
"You are more worried when you are waiting to see her, that when you curtsey you might fall over," she said.
When being presented with the award, Mrs Keen said the Queen asked her about the PCP, and whether it was proving successful.
Mrs Keen has been involved in the PCP, which also serves Chiddingfold, Churt, Thursley and other surrounding villages, since it began nine years ago.
In her role as chairman she has served as a contact point between the police and the community.
"We hold public meetings as and when people require them," she said. "For example during the Beacon Hill arson problem, we were able to reassure residents by bringing the right police representatives to speak with them."
Nominated by the local police, Mrs Keen said that it was still a surprise when she learned she was actually to receive the honour.
"I was very surprised," she said. "I know that there are a lot of people in Haslemere who do more for the voluntary services than I do. Even to be nominated is an honour."
Her friends and family have been thrilled that a local person they know has become an MBE, but Mrs Keen insists the award will not change her. "I'll still be the same Jackie Keen I've always been," she said.
Mrs Keen has served on Haslemere Town Council for 18 years now and was mayor in 1995/6.
She said: "I'm the second longest-serving councillor after Ted Orchard. We say we're like the granny and grandad of Haslemere Council!"
