I think your problem is that you think by just throwing some technology together you have struck gold. I think you haven't. And you attitude is a problem. No, the word doesn't owe you anything for this "bright" idea. Because it isn't that bright. At best it it a technology study. When GSM was new it was very popular among students here to do projects remote controlling something via GSM. It has worn off in recent years. I see nothing more than yet another technology study.
Some things you apparently haven't thought through:
The lifetime of a USB stick connector and matching socket at your lock is horrible, compared to the lifetime of a conventional key.
Door locks, door peepholes etc. are build to electrical and mechanical standards. Different standards, depending where you are and what the door is for. Which standards do you adhere to? Did it even occur to you that door locks around the world are different?
How is your PCB with antenna supposed to fit into a door (yes, most modern doors have their electronics inside the door) or at the door? In fact I don't see that you have thought through the whole mechanical side of things.
And what happens when the power or the network fails?
And I don't think you have thought through the whole electrical interoperation, e.g. with existing intercom systems, existing electrical bolts, existing electronic peepholes and cameras, existing electrical doorbells. Just a PCB and some three letter buzzwords like GSM and USB aren't enough.
