Door won't unlock with key
 

I am having a problem. I installed a new radio in my 2000 Boxster and it was functioning fine. I locked the door and when I came back the key doesn't unlock the car. Nothing happens. Does anybody have any idea what happened and how I get the car unlocked?

Sorry man, but correlation does not equal causation...unless you were in the door cavity.

I didn't know if this is an alarm/security issue dealing with the radio or if a wiring problem with the radio could have lock down the car.
