Rear hatch lock question:

I have a rear hatch lock that won't unlock anymore.

The electrical hatch release works fine, but the key turns and turns and turns...

I pulled it apart today. The arm of the lock that presses down on the white nylon plastic arm moves a little bit...but won't press down hard enough on the nylon to pop the hatch.

Q: My car has the alarm. Would the non-alarm part work? I would take the non-alarm part and simply bolt the alarm switch at the end onto it. That, or since I disabled the troublesome central locking on my car 10 years ago....simply leave it disconnected.

The correct part at 928Intl. is $450. The non-alarm is $150-

Thanx!

Norm........the rear hatch parts were updated and are available through 928srus.

They can fix you up as well as install details.

What he is selling is the white rubber "tub" that sits on the rear end of the car and receives the hatch tongue. That isn't what I need. My tongue won't move enough because the metal part behind it won't put enough force onto the part it is supposed to hit on.

[shut UP! I'm having a little fun with this as usual~]

It just spins in the hole....

Any ideas?

Normy,

Good to hear from you, your tongue, and your warped sense of humor again...

There have been several jury-rig solutions over the years. I'm not sure what is going on in your latch (I haven't looked at the latch workings in several years), but you can replace the white plastic latch. Cheap, and might help - they do wear.

Some folks have shimmed the metal tongue. One guy cut a strip from an oil bottle, bent it into a U, and slipped it over the tongue.

If the hole in the linkage is reamed out too much, perhaps installing a home-made bushing from small brass tubing would reduce the free-play enough to get a climax...

Wally: Battered but unbowed. Even quite shiny. And as profane as always, trust me-

I don't think the plastic part is the issue. I suspect the lock cylinder. The reason I suspect this is the fact that the key will turn and turn and turn in the same direction; Something metal has broken inside the cylinder. That's what happens in the door lock cylinders- The "pot metal" part breaks, and then it wont put force on the lock mechanism.

-The strange part is that it puts PARTIAL force on the plastic. But not enough.

What I think defines this problem is the fact that the key can turn at the same RPM as the crankshaft. Prior to this, my key in the hatch would turn, and then the hatch would pop open. It couldn't turn around and around and around. Something broke. But is this lock cylinder the same as the door locks? It makes sense to me from a production cost perspective for Porsche to have asked their parts supplier for the locks to supply the exact same lock cylinder and actuator tab for the hatch as the door locks. If this is the case, then a cheap door lock cylinder from one of the 928 vendors would solve this problem real quick.

-That stupid metal tab on the door lock cylinders! I swear I'm going to buy a metal lathe and some tools and make these out of billet steel some time!
