The electronic lockers are part of a transition from the one-locker-per-person system to a Smart-card key system where lockers will be made available on a first-come first-serve basis.
"We're always looking for innovative ways to use technology to provide environmentally friendly choices and this is one of those ways," said VTA spokeswoman Jennie Loft.
Of the 500 existing lockers at light rail and Caltrain stations, Park and Ride lots and transit centers, 61 have been upgraded and an additional 35 will be complete by the end of June, Loft said.
Loft said there has been greater demand for the lockers since the retrofitting, especially at light rail stations.
"They are more efficient for our riders who are using bicycles, because when they're assigned a card key they can visually see a locker that is available," Loft said.
The electronic lockers cost $20 and are available at four locations in San Jose, including River Oaks Park and Ride Lot, Branham Light Rail Station, Tamien Light Rail Station and Ohlone Chynoweth Light Rail Station.
The Winchester Light Rail Station/Transit Center in Campbell offers the new lockers, as well as the Great Mall Main Street Light Rail Station/Transit Center in Milpitas.
The upgrading of the lockers was funded by the 1996 Measure B Program.
