Central locking weirdness and beeps

[Modded996]

My 996 ('02 C2) is becoming allergic to hot and humid weather. When the temperature is moderate, I don't seem to encounter any problems. Anyhow, so what tends to happen is that the central lock will activate and occasionally deactivate when I'm driving. If I attempt to turn it off, there's an 80% chance it will unlock, then lock and then beep twice. The other 20% of the time it will just do what its told (but with another 80% chance that it'll relock at some point). When I open either car door afterwards it will double beep. Also, if I attempt to use the key fob to lock the doors at that point it will lock unlock and double beep. The security light is blinking properly and there aren't any fault lights illuminated. Also, the armrest is securely closed. Having searched around online, I haven't run across the same exact issue, but I'm sure I'm not the only person to have had it. Does anyone know what is going on or have any ideas I can test? I'm thinking that I'll have to take it in otherwise. Thanks!

If you are getting two beeps when locking then there is an alarm fault.

You will need to read the alarm system faults with either the Durametric software, a PST2, or PIWIS tester and report the fault(s) back here. Everything else is just a guess without the alarm faults.
