Doors not unlocking/central alarm fault
 

I have a 2000 986 boxster with the issue that whenever I try to use the key fob lock/unlock function you hear the car lock then it sounds like it attempts to lock again followed by the alarm horn sounding twice. From this state the only way to unlock the car is to use the key manually on the driver's side and the passenger side has to be unlocked from inside by using the door handle twice. I recently purchased a durametric and the alarm fault code it gives is 47. Anyone know what this code means and what do to begin troubleshooting this problem and get my car back to where it will unlock with the remote key fob? Thanks guys

It's a door lock assy. Left or right.
