I hate to be cynical, especially with a group name like mine
but you might be better off studying electronic engineering and/or computer engineering.
More and more mechanical locks are being made overseas now it seems as costs are lower. The few companies who still manufacture in the west, probably have more mechanical engineers than they know what to do with. To get them to take you on, the competition level might be very high indeed.
With locks themselves seeming to be sliding towards electronic mechanisms, or computer-controlled access, that might be a more secure future if you are sure.
