So over the weekend, I added a dynamat trunk kit to my car and used the expandable foam on my car. While i now have no more rattles, and my system sounds alot better, I can't open my trunk. I am guessing some of the foam got into the lock and its closed it up. I can put my key in the keyhole and turn it, but it dosent do anything. Pressing the button in the center counsole, while it used to be a "clicking" sound, now is just a "knocking" sound. I have tried lifting up with all my strength, nothing. I am deciding on to drill a hole where my license plate it and hoping I can see whats wrong. Does anyone else have any other ideas? Would a locksmith have any ideas?
