so after sitting down for an hour and playing, i figured out what "key" combination works for my new key. i got the ignition lock, and a door lock done so far. but, as i was finishing getting the pins in...... (gurrrrr), what should i use to lube the locks? the stock "grease" was choked with grime. is graphite still the best idea?



Quack,

I've been very happy with a little wiping of silicon dielectric grease in both sets that I've keyed.

thats not a bad idea..

Any grease will only attract dirt, debris, dust etc. to stick to the grease turning it to the choking grime you found on the old ones. Graphite is the prefered lube.

Is there a preferred method to clean the locks of said grime?

The silicon grease works perfectly, no mess on key. just a very thin coating of the parts inside the lock is all it takes.

WSM doesn't appear to be too high on graphite as it is conductive.

Not sure what the Porsche recommended material consists of, see tech brief for all models, below

I have had success in the past by dismantling the door locks
as far as possible then boiling the parts in water in a small pan.
This melts off out dried out oil/ grease together with the dirt.
Used the same method to clean the innards of old mechanical
speedos and rev counters.
Locks are best lubricated with dry graphite powder applied by
a puffer. I haven't been able to source this lately so I have used
dry teflon lubricant from a bike shop( Finish Line Dry Teflon Plus).

Anything oil/ grease based will just attract and hold dirt
and should never be used..

For cleaning I blew brake cleaner through the assembly, then disassembled and re-keyed. Before installation I sprayed a bit of Tri-Flow aerosol into each end of the cylinder.

Good alternate recommentations!
Locks like graphite, not Alarm locks, though.

ZERO luck locating the Porsche grease 999-917-751-00 listed in the Technical Service Bulletin Group 5 Number 8501.

Try this stuff called Superzilla. It does a lot of thing from penetrating fluid to lubricant. It does work better than the know penetrating big guys. Used on ‘85 for door lock, as well as ignition and all work smoothly now. Nice smell and No petroleum products, just plant base formula.
Amazon sells it, or buy directly from them. Takes grease out of clothes too!

That is because it got superseded by part# 000-043-305-02.

It's under $20 from anyone including the dealer.

Thanks. I have seen that new part number listing.

The description for the old part number, 999-917-751-00, is: "Jelly Type Door Lock Grease", with zero mention of anything regarding low temperatures.

The description for the superseded number, 000-043-305-02, is; "Universal Low Temperature Grease", identifying the temperature characteristics and zero mention of the lock application.

It raises questions w/ me that these two products (part numbers) are different.

Not a huge impetus for me to rush out for the new P/N for a vehicle operated in tropical climate.

The other number Porsche gives for a door lock grease is 00004330627.

This is a spray type grease and has a similar price ~$20.

This one is more for the lock tumblers while the one posted above in the TSB is more for the door lock assembly itself.

Basically use the spray if it feels gummed up and is hard to get the key in, and use the grease if it is hard to turn.

Either way, they should both help a sticky lock. Just don't use graphite powder as it is conductive and will mess with the alarm contacts at the back of the lock.

I have used Wurth HHS-K aerosol grease on all the locks, keys etc. It comes out of the can a thin liquid, then congeals. Tiny amount is all that is needed. And, as such the dust/grime accumulation is minimal.
