Locked my key in the trunk...

[EIP11]

So today after a 3 hour long drive I began to take my suitcases out of the trunk of my car, however being the attentive person that I am I closed the trunk lid with the keys still inside and all of the door locked. My closest spare key is 3 hours away, I've done some research on the forum and apparently I can get into my car if I remove the trim around the license plate lights and pull a lever? However I'm not very clear on how to do it without risking breaking the trim. Therefore can anyone give me more information on how to properly do this?

Thanks,
Elvis
