Cernunnos Posted September 7, 2020 Report Share Posted September 7, 2020 1 hour ago, StockBottom said: Many of these digital locks are driven by solenoid to open or close the lock and thus a reasonably strong magnetic would be able to move the solenoid as well and thus defeat the lock with faster time than you need time to pick a mechanical lock. Digital locks still needs a lot of work to increase their security levels to sufficiently match the mechanical ones but that does not mean mechanical locks are always secure either but they take more effort the learn to pick rather than simply using a relatively strong magnetic to a solenoid and pop goes the lock.
