Micro SD card slot jammed

We use GoPros often on our snorkel trips, and have found that after about a year, the micro SD card slots start malfunctioning. There is usually a very satisfying click that your can hear and feel when you've successfully input a micro SD card into the GoPro Hero 3 Silver.

When the mechanism wears down, the click doesn't happen, and the heart breaks into tiny little pieces. You can't get the micro SD card out easily-- it feels like whatever spring mechanism is in the device has simply worn out.

How do we fix this? There's got to be a relatively simple way.
