Door lock/unlock problem

[thom4782]

Them double beep means there is a fault in the locking system. My guess is the electronic lock part has broken. There are a few other mechanical parts involved that connect the handles to the locking mechanism, but they seem less likely because neither handle works. Other than taking the door apart, you would need a diagnostic computer to read the fault codes to narrow the cause down further.

Do only porsche dealers have the diagnostic computers, or would my local garage's diagnostic computer work with the locking system on the porsche?

A local repair shop that works on Porsches should have a diagnostic computer. Durametric makes a cable that works with a laptop and its almost as powerful as the Porsche computer. Autologic also make a diagnostic computer. If the local shop has one of these, you're in luck
