Montoya started his professional career with Belgrano in the 2000 Apertura of the Primera División. He became a starter for Belgrano during the 2006 Clausura of the Primera B Nacional (second division), relegating Colombian international Robinson Zapata to the bench. Belgrano was promoted at the end of the season and Montoya played his first full season in the first division in the 2006–07. However, his team was relegated at the end of the season.
After Belgrano's relegation, Montoya stayed in the first division, being transferred to Vélez Sársfield. At first, he was a substitute for Sebastián Peratta, but became a starter from the 12th fixture onwards due to a knee injury suffered by Peratta. During the 2008 Apertura, Montoya was originally a starter, but was relegated by Marcelo Barovero by the end of the tournament. Subsequently, when Ricardo Gareca replaced Hugo Tocalli as the team's coach for the 2009 Clausura, Montoya regained his position as a starter. Vélez won the tournament and Montoya had the lowest goals-to-games ratio, therefore being awarded the Ubaldo Fillol Award.
