# Trying to increase amperage of Arduino Uno digital pin (20mA) to control a cabinet lock that is rated at 12v / 2A

I am trying to use my Arduino Uno to send power from one of its digital pins to a cabinet lock, the cabinet lock is "fail-secure," so you send power to it to unlock it, and it is locked when in GND state. I purchased these, but being new to electronics, when I bought them, I failed to realize that I would need to increase amperage as well as voltage to make the lock function.

Alas, I had this lying around. I know it works with DC motors, but I was wondering if I could use it to increase the current for the lock. I'm trying to understand the specs - in some places I see that it can produce 600mA, in others I see 1.2A or 2A. If it can produce 1.2A from 5V, I think maybe that would open the lock (I don't know the minimum amperage that would open the lock). The specs seem to be for two models, I have the L293D.

So my overarching question is, can I connect the Arduino Uno digital pin to the L293D and then run the output from that to the DC boost module I got (amazon link above), and then run the output from the DC boost module to the lock...with enough amperage to open it?

Here are some pictures of what I have (I am still awaiting the DC boosters in the mail):
