Andersen began his career with Danish club AB Copenhagen and became the youngest goalkeeper to play in Danish senior football. He joined Reading on a two-and-a-half-year contract on 26 January 2007, having played seven times for AB.
He returned to Reading having played three times for Torquay during his one month on loan and looked set to remain with Reading for the remainder of the season. However, he joined Rushden & Diamonds on a seven-day emergency loan on 15 April 2008, making his Rushden debut in a 2–1 win at home to Torquay. He also played in the defeats against Exeter City and Oxford United before returning to Reading.
In December 2008, he was again signed on an emergency loan, this time for Brentford, whose first-choice keeper Ben Hamer, also borrowed from Reading, was suspended. He was named MOTM and Team of the week for his performance in this one game.
On 20th September 2014, he made his full debut for the club in a 1-0 defeat away to Sheffield Wednesday since arriving in 2007. 
Bristol Rovers (loan)
On 1 September 2009, deadline day, Andersen was signed on loan by Bristol Rovers until 1 January. He made his debut against Millwall which Bristol Rovers won 2–0, keeping a clean sheet, and went on to play in all eighteen of The Pirates' league games during his initial four-month spell. Shortly before the deal expired, it was extended for a further four weeks, Rovers wanting to keep him until the end of the season, but managerless Reading wanted to appoint a new boss before committing him to a longer term move.
At the end of January, Andersen finally extended his loan spell until the end of the season, as Reading appointed caretaker boss Brian McDermott on a permanent basis. On 20 March, Andersen played against two other on-loan Reading players Scott Davies and Alex McCarthy. He kept a clean sheet from that game which ended 3–0 to Bristol Rovers. On 5 April, he saved a penalty from Milton Keynes Dons' Jermaine Easter as Rovers won 1–0, keeping another clean sheet this penalty save was his first ever one.
By the time his loan spell in Bristol had finished, Andersen had played 39 League games for The Pirates. He was awarded the League One side's Young Player of the Year trophy, and was also ranked third in the overall Player of the Year poll.
On 2 August 2010, Bristol Rovers re-signed him as they cancelled the loan of West Brom goalkeeper Luke Daniels because of a back injury.
Andersen finished his loan spell with Bristol Rovers on 5 January 2011.
On 17 August, Andersen joined Portsmouth on loan for one month. He made his debut in an Npower League 1 game against Bournemouth, the game ended in a 1–1 draw. Andersen's loan was extended for another month on 18 September and again extended in October. Andersen's loan came to an end and he returned to Reading following Portsmouth's 2–3 defeat to Leyton Orient on 20 November 2012.
After signing for Reading, Andersen played three games for the Danish national under-19 and under-20 teams during 2007. He made his debut for the Denmark national under-21 football team in February 2009, replacing Jonas Lössl at half-time. While on loan at Bristol Rovers, Andersen re-entered the under-21s for an October 2009 friendly against Georgia, but served as back-up for Lössl. He replaced Lössl for the Under-21 games in November 2009 and March 2010, playing a total of three under-21 national team games. In May 2010, he joined the under-21 team for a series of unofficial games at the international 2010 Toulon Tournament. He made four appearances as Denmark finished runners-up, and was named goalkeeper of the tournament.
