>> Thieves can bust into them, as California surfers have learned >> California surfers say they're "under attack" by car thieves—and warn that anyone else using a lock box is vulnerable. Surfers often use lock boxes to hide their car keys while surfing at beaches in San Francisco. The problem, as the San Francisco Chronicle reports, is that lock boxes can be broken into in about 10 seconds using a simple tool, as demonstrated in numerous YouTube videos. "I wish I'd known before how insecure these things are," a surfer whose car was stolen from China Beach tells the Chronicle. "You're basically advertising to thieves, 'Here's my key; go ahead take it.'" Motor vehicle thefts were up 49.5% from April 1 to Nov. 15 in the city's Taraval and Richmond police districts—which include Ocean Beach and China Beach, respectively—compared to the same period in 2019, per the Chronicle.
