Several of his students became cathedral organists and professors. He played the organ in the local parish age 9. From 1969 to 2003, Lehrndorfer also worked in the position of organist at the Munich cathedral Frauenkirche.
A particular focus of his artistic activity is organ improvisation.
In 2001, he played the premiere of Harald Genzmer"s Concerto for organ and edited it for publication by Schott Music. He composed mostly works for organ, such as variations on the carol "O du fröhliche", and sacred music
Lehrndorfer designed several major organs, including in 1980 the new organ of the Tegernsee Abbey with 33 stops, three manuals, a pedalboard and mechanical wind chest, made by Georg Jann. In the summer of 2008, on his 80th birthday, former students organized a major concert series in the Frauenkirche.
In honor of Theobald Schrems, Lehrndorfer composed the Missa in memoriam Theobald Schrems for four-part male choir.
He died in Munich.
A choir of former members of the Regensburger Domspatzen premiered the work on 9 November 2008 in the Regensburg Cathedral.
