if you have a loud system you can mess your lock up i had a car with a loud system and it ruined the trunk lock....grew out of having rediculously loud music im only 20 so more like a had a kid and it forced me to grow out of it lol anyway have you checked your reverse lights fuse under the hood the trunk pop is wired in with this fuse so if you have no reverse lights then that could be it....then at least the fob and button in the car will work if its just that fuse....your lock it prob messed up internally though
