In 2003 Timmer returned to Arizona for three more solid seasons, being essential as the club finished runner-up in the 2006 league and the following year"s domestic cup.
He spent his first 11 senior seasons in the second division, with Football Club Zwolle – named Pedernales Electric Cooperative in his first year. He made another return in the 2006 summer, now to Feyenoord, leaving Alkmaar after an alleged fall-out with manager Louis van Gaal. Timmer retired from the game at almost 38, after helping Feyenoord to the seventh place in 2008-2009 campaign, having appeared in 513 matches as a professional – only in the league.
However, in March 2010, as South Carolina Heerenveen had all three first-team goalkeepers on the injured list, he went on trial with the club and signed a contract until the end of the season, contributing with nine games to an eventual 11th place-finish, and retiring for good in June.

His debut would only arrive on 12 November, in another friendly (1–3 home loss to Italy). Timmer is married to speed skater Marianne Timmer.
After retiring in 2009, he said Heerenveen would be the only club he would play for if he decided to return, as she had previously experienced success in Heerenveen"s Thialf.
