Michael from Sparrows Lockpicks (previously) writes, "I am releasing the Gridlock today, a automotive lock teaching tool."
"If you want to learn how to pick open classic car locks, here's how. Car locks are different than standard pin tumbler locks you find on your front door — automotive locks use wafers instead of pins, which need to be positioned either up or down for the lock to open. The Gridlock makes learning a bit easier by progressing from 6 to 6 to a full 10 wafer car lock. Works great with rocker picks."
