Born in Aylesbury, England, Boyce started his career at the age of sixteen as an apprentice at Luton Town. He rose through the ranks and eventually established himself in the first team, and went on to make 185 league appearances for the club, scoring eight goals.
He joined Crystal Palace on a free transfer in 2004, where he played in the Premier League for the first time, but he and his teammates were unable to prevent the club from being relegated to the Championship. He spent two years at the club, making 69 league appearances and scoring one goal.
After Crystal Palace failed to gain promotion, Boyce returned to Premier League football in 2006, this time with Wigan Athletic after completing a move for a fee of £1 million, and was a key player during his first season when the club narrowly avoided relegation. He remained an active member of the first-team throughout his spell at Wigan, and is the club's Premier League appearance record holder. In May 2013, he captained Wigan Athletic to victory in the 2013 FA Cup Final in a 1–0 win over Manchester City. He last played for Blackpool in the 2015–16 League One season.
Boyce has also represented the Barbados national team, making his debut for the side in 2008.
Boyce was born on 24 September 1979 in Aylesbury, Buckinghamshire. He grew up in Elmhurst with his parents, Lucille and Melvin, and attended Quarrendon CE Secondary School, where he set athletics records. He began playing football for his local team Aylesbury United F.C. at the age of ten. He played as a striker for two years before being moved to his more familiar position in defence. Boyce was initially unhappy about being moved into his new position, but coach Steve Greenhalf believed Boyce could successfully become a professional footballer as a defender. From the age of twelve, Boyce attended the Luton School of Excellence, and in the summer of 1995 he became an apprentice at Luton Town.
Boyce spent three years playing for Luton's youth team, where he played alongside Gary Doherty and Matthew Upson. The team reached the semi-final of the FA Youth Cup in 1997. He signed professional terms with the club in 1998, and made his debut on 5 January 1999 in a 3–0 home defeat against Walsall in the Auto Windscreens Shield. He appeared once more later in the season, making his league debut in April 1999, in a 1–0 defeat against Lincoln City. At the start of the following season, he was regularly on the substitutes bench, but due to the poor form of first choice right-back Stuart Fraser he was given the opportunity to start the match at home against Chesterfield on Boxing Day. He kept his place in the starting lineup and played 30 times in the league during the season, and scored his first goal for the club in a 2–1 defeat against Bournemouth in February 2000. Boyce started the 2000–01 season in the centre of defence. New Luton manager Ricky Hill praised Boyce for his "tremendous" displays, and felt he deserved a call-up to the England under-21 squad. He played 42 times in the league, scoring three goals as Luton were relegated to the Third Division.
Boyce was a key figure in the following season for Luton as they gained promotion back into the Second Division, and he was rewarded with a new two-year contract. Despite strong competition for places, he continued playing regularly for Luton in the 2002–03 season, making 34 appearances in the league. During his final season with the club, he made 42 league appearances, scoring four goals, and his performances were recognised when he received the Players' Player, Supporters' Player and Internet Player of the Season awards. In the summer of 2004, he rejected a new contract with Luton and decided to leave the club after his existing contract expired.
Following a short trial, Boyce moved to Crystal Palace in July 2004 on a free transfer, signing a two-year deal with the club. He made his debut on 14 August 2004 in Palace's opening Premier League game against Norwich City, and quickly established himself as the club's first-choice right back, and played in almost every league game for the club until a foot injury in March 2005 ruled him out for the rest of the season. The incident occurred during a training session, shortly after Boyce had signed a new deal extending his contract until 2007. Palace were then relegated on the final day of the season after drawing in their match against Charlton Athletic. He returned to the starting line-up in the first game of the new season in the Championship against former club Luton Town. He was a near ever-present throughout the campaign, making 42 league appearances for the club, and scored what would be his only league goal during his time at Palace in a 2–0 win over Coventry City in November 2005. Palace missed out on promotion however, losing in the play-off semi-finals to Watford. Boyce had become a favourite with Palace fans and was voted Player of the Year in 2006.
With 12 months remaining on his current contract, Boyce rejected a new deal with Palace, stating his desire to return to the Premier League. Rather than letting him leave for free at the end of his contract per the Bosman ruling, Palace accepted an offer for Boyce from Wigan Athletic.
On 1 August 2006, Boyce was signed by Wigan Athletic on a four-year deal for an initial fee of £1 million. He was initially signed as a replacement on the right side of defence for Pascal Chimbonda, but was often deployed as a centre back. He made his debut for the club on 19 August 2006 in a Premier League match against Newcastle United. He made 34 league appearances during the season, helping the club avoid relegation, which was confirmed on the final day of the season in a 2–1 win against Sheffield United. His performances earned him praise from Wigan supporters, and he narrowly missed out on the club's Player of the Year award.
At the start of the 2007–08 season, following the signing of Mario Melchiot as the club's new first choice right-back, Boyce found his first team opportunities more limited. However, after a poor start to the season by Wigan, he returned to the starting line-up, which saw an upturn in results, and the club once again avoided relegation. He made 25 league appearances during the season, most of which came during the second half of the season.
On 15 November 2008, he was sent off for the first time in his career in a 2–2 draw against Newcastle United, after receiving a second yellow card. Replays showed that the decision was harsh, and Wigan manager Steve Bruce called for rule changes to allow clubs to appeal against yellow cards, and also to introduce video technology. Two weeks later, on 29 November 2008, he scored his first goal for Wigan, a header from the edge of the area in a 2–1 win against West Bromwich Albion. He finished the 2008–09 season with 27 appearances.
In July 2009, he signed a new contract at Wigan, keeping him at the club until 2012. The 2009–10 season was a frustrating one for Boyce. Under new manager Roberto Martínez, he was initially part of the starting line-up, but after being replaced by new signing Gary Caldwell in January, his playing time became more limited. He played 24 times in the league, scoring three goals — the most he had scored in a season since leaving Luton.
Boyce was back in the starting line-up at the beginning of the 2010–11 season, but suffered an injury against Bolton Wanderers in October 2010. He was initially expected to recover in two weeks, but was sidelined for considerably longer after aggravating the injury in training. He returned to the side on 8 January 2011 in the 3–2 FA Cup victory against Hull City. He appeared 22 times in the league, and started in the final game of the season against Stoke City, making a goal line clearance in the first half to keep the score level. Wigan went on to win the game 1–0, securing Premier League survival on the last day of the season for a second time. Boyce was the only Wigan player to play in both the Stoke game and the match against Sheffield United in 2007.
In August 2011, Boyce signed a new two-year contract at the club. On 25 February 2012, he made his 146th Premier League appearance in a 0–0 draw against Aston Villa, making him the club's record holder for most appearances in the Premier League. On 21 April, he scored his fifth league goal for Wigan in a 2–1 away defeat to Fulham. On 9 May, Boyce was given the outstanding achievement award at Wigan's end of season awards. He followed this up on 13 May, the final match of the season, by scoring two goals against Wolves, including a spectacular volley from outside the penalty box.
In May 2013 he captained Wigan to win the FA Cup over Manchester City and jointly lifted the cup with non playing club captain Gary Caldwell. In March 2014, he was once again instrumental in captaining Wigan to an upset over Manchester City, this time in the 2014 FA Cup Quarterfinals.
In August 2015, Boyce ended a 9-year stay at Wigan and joined Blackpool on a free transfer. He was then released by Blackpool following their relegation from League One.
Though born in England, Boyce was also eligible to play for the Barbados national team through his parents Melvin and Lucille, who were both born in Barbados. Boyce earned his first international call-up on 20 March 2008, aged 28, stating that "The appeal is to play international football. I consider myself a Barbadian and I feel it's the right thing to do to play for my country. I am really looking forward to it." He made his debut for Barbados in a 2010 FIFA World Cup qualifier against Dominica on 26 March 2008, in a 1–0 win which advanced Barbados to the second round of qualifying. His other appearance for Barbados that year came on 22 June in a 1–0 defeat against United States. Boyce was called up again for the 2014 World Cup qualifiers and captained the squad in a 2–0 loss to Guyana in Bridgetown. He was recalled to the team in 2014 and captained the squad during the 2014 Caribbean Cup qualification. He scored his first international goal in the 4–1 win over Bonaire that qualified them for the next round.
