986 boxster central alarm issue

[r3v01u7i0n4ry]

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

Welcome to RennTech

Looks like you have an alarm fault.  As you have the Durametric, you should be able to read the last ten alarm faults stored in the DME, which will point you to the source.

That's what I've done. After clearing all the faults, I waited a day and then rechecked the listed faults. The only listed fault was alarm fault 47. I believe it has something to do with the drivers side door. I say this because earlier today I was seeing how the car reacted when attempting to lock it under different scenarios. When the driver's door is open and I attempt to lock it the cars alarm horn beeps once. When I shut the driver's door and open the passengers door and try to lock it the cars alarm horn beeps twice, and when both doors are shut when I try to lock it the car beeps twice.
