Trunk doesn't lock!
 

I noticed that when I lock my doors, my trunk doesn't lock. I tried locking it manually with my key, but when I stick the key in, it's not letting me lock the trunk (it's not letting me turn it to the left or right). I made sure to see if my key works with my doors & it did.

Anyone experience this before?

Fuse?
Vacuum line to pump issue?
The actual lock broken?

Any help will be appreciated

Thanks!
