Central locking fault?

[Guest]

Hopefully I've done something stupid with my new 993 and it hasn't started to fall to bits already!!
The light on the central locking botton on the console is constantly on when the ignition is on, and the passenger door cannot be opened from the outside at all.
The drivers door locks and unlocks via the alarm remote just fine.
All was well yesterday morning.
It's only a few days since an OPC gave the car a clean bill of health on a PPI, so hopefully it's me!!
Please advise.
Thanks
Andy

Hi Andy

You say the passenger door can't be opened from the outside at all. Is the pull trigger on the door handle operating normally, or has it lost its spring return? One problem is that after periods of inactivity, over time or even due to changes in atmosphere, the barrel that is operated by the pull trigger seizes up and sends the whole locking system haywire. Very easy to fix, although it is a door panel off job. I won't go into too much detail yet in case I'm thinking of the wrong problem, so if I'm on the right lines, let me know and I'll talk you through the fix.

Regards

Hi Oliver
Just tried the key. If the passenger door is unlocked with the key, then it can be opened from the outside. The handle seems fine. It then needs to be locked with the key again, the remote won't lock it (but does lock the drivers door).
Hope that helps!!

Different problem than the one I was thinking about. One possibility though is that the actuator could be stuffed or disconnected from the lock in some way; (the motor that operates the locking mechanism when it gets an impulse from the alarm). Other than that, possibly broken wiring or a faulty alarm control unit, although I'd think the latter to be fairly unlikely. Best bet may be a diagnosis from an alarm specialist, a Porsche specialist or an OPC, unless anyone else has any suggestions.

Hi Mate,

Having had a major problem with my central locking just 2 days ago may I suggest you check the connections and plugs on the alarm brain under the drivers seat. My car would lock then unlock immediately although the alarm set ok. Problem traced to the plug on the brain coming disconnected when the seat had been moved back & forward by my local garage after some routine work.

Hope this helps as a new alarm brain is around £400.00!!!
