Born in Caen, Dikamona started his career in 1997 with local youth side Caen Nord, where he spent two years before the club folded due to financial reasons. He then moved on to US Guérinière where he spent a couple of years, also frequently playing against the youth teams of SM Caen. It was in one of these games that he was spotted by scout Gilles Deshors and invited to play for the SM Caen youth side, signing for the club in 2001. He progressed through the various youth sides and was promoted to the reserve side in 2008 at the age of eighteen. He spent two seasons playing for the reserve side but was not offered a professional contract with the club after a dispute with the owners. He spent time on trial at Lille OSC and was offered a one-year contract, but signed for Ligue 2 side Le Havre AC after they offered him a three-year deal. In his first season with the club he drifted between the first team and reserve side, making his professional debut in February 2011 in a 1–0 win over Clermont Foot, replacing Mody Traoré as a substitute. In October 2011, he received a request to join Football League One side Sheffield Wednesday on trial. Sheffield Wednesday were keen on completing a deal, however a fee could not be agreed and Dikamona returned to France. In the winter break he returned to England with Football League Championship club Nottingham Forest on a one-week trial, however again a deal could not be agreed. On his return he spent the remainder of the season with the reserve side. The following season, he was close to signing for Championnat National side US Boulogne on loan but the clubs could not agree a split in wages. In November 2012 he joined Championnat National side Fréjus Saint-Raphaël on loan until the end of the season. He became a first team regular for the side that challenged for promotion to Ligue 2, but missed out on the final day to CA Bastia having only needed a point to secure promotion. Following the completion of his loan Dikamona was released by Le Havre and became a free agent. He later signed for CFA 2 side CS Sedan Ardennes on a free transfer, who had recently been demoted from Ligue 2. He was a first team regular making nineteen appearances and scoring three goals as the side finished in second place, gaining promotion to the CFA. He had the option to stay for another season with Sedan, however, he moved up a division to Championnat National side Poiré-sur-Vie. He was a regular for the first half of the season but then picked up a thigh injury which ruled him out for the majority of the remaining campaign. At the end of the season Poiré-sur-Vie were demoted due to financial reasons and Dikamona chose to leave the club and went to train with the UNFP. Due to his agent living in London, he earned himself a trial at League One side Oldham Athletic. A deal could again not be agreed and he joined Football League Two side Dagenham & Redbridge in August 2015 on trial for a friendly match against Crystal Palace. He impressed manager Wayne Burnett with his performance and signed a one-year contract with the option of a further year. He made his debut a week later in the 4–1 away defeat to Charlton Athletic in the Football League Cup. In May 2016 as his contract expired, he was released along with eleven players as Dagenham were relegated to the National League. In July 2016, after spending a week on trial at the club, he signed for Ligue 2 side Bourg-Péronnas on a two-year contract. On 15 July 2017, Greek Super League club Platanias officially announced the signing of Dikamona on a two-year contract following his release from Bourg-Péronnas. After a spell with Israeli club Bnei Sakhnin, Dikamona signed a one-year contract with Scottish Premiership club Heart of Midlothian in September 2018. He extended his contract by another year in March 2019. Dikamona left Hearts in March 2020.
