Master Key System in San Mateo, CA

Master Key System in San Mateo should be simple: one call, a fast arrival, and a job done properly. That is how Bay Area Lock And Key works every day, serving San Mateo homes, businesses and drivers with mobile, on-site service.

A master key system lets one key open many doors while each individual key opens only its own — so a manager or owner carries a single master while staff access only their areas. We design and install master, grand-master and sub-master systems for businesses, apartment buildings and institutions, mapping keys to your exact access needs.
