Re: fas 6890

The 6880 I have is only very slightly oiled where the levers are. If you put something inside you have to ensure that is an oil which will NOT harden over time. You could look into the open lock and try to determine why it gets stuck. Maybe there is a reason which can be identified and removed.

Btw. what is the techical dfference between the 6880 and the 6890?

The 6890 is X Ray Proof.

Re: fas 6890

I read something like this, but the 6890 I have doesn't look like that. For this I would have expected the parts on the bolt side to be made from plastic, but they are not. I can't see any difference besides the two locks besides the sticker and I haven't heard of forged/manipulated locks. Also being x-ray proof is in Europe no reason to get a higher security rating.

Re: fas 6890

I do not have already control inside parts of 6890 to compare with to 6880.

Have you seen fe a lead shield between the lock case and levers ?
Levers are still brass manufactured ?

Re: fas 6890

No lead shield, still brass levers. My 6880 weighs 658g, the 6890 653g.

Re: fas 6890

6890 has an antipressure device to bind the bolt when pressure is applied to the levers to try to pick the lock.

Re: fas 6890

So I should disassemble both locks completely to find the difference?

Re: fas 6890

Yes if you want, they can be a bit of a pig to reassemble sometimes, put all the levers back in the unlocked/retracted bolt position to hold them in place during reassembly, and then reset them with a key back to the locked position afterwards.

Re: fas 6890

Since we're on the topic of FAS locks, I have a 6870 I've been pondering... I've read the FAS locks are impossible to pick without a buildup tool, but from looking at it I can't figure out why. Seems like it should be possible with a 2-in-1 tool or wires if you can modify it to fit around the warding at the very back. Am I missing something that would make fabricating a pick a waste of time?

Re: fas 6890

I would never say that something could not be picked a certain way, because there are some very skilled pickers about. The problem as I see it would be the tiny sized keyway and sometimes relatively long keys, so to me if using wires you would get a lot of flex/spring and lose a lot of feel, it is probably doable, but I wonder about how consistent and quick you could be doing it this way.

Re: fas 6890

Found the difference. Similar to the Hobbs' Protector lock. Neat. Is PIn & Cam still possible with this mechanism?

I reassembled the lock in the unprogrammed state. That way no key was necessary for closing.

Well, I have a 2-in-1 that I made for the 6804 that fits in the keyway... the tensioner will need to be modified to get all the way to the back with the warding, but it feels like the pick works to lift the levers, and the levers themselves are cut away enough on the opposite side to allow the pick to swing all the way around. The warding doesn't extend into the lever stack, so it seems like it should be possible. Have a long weekend coming up, so may experiment a bit and see what I can figure out.
The pick I made is long enough for 3" thick doors, and I have no real idea where these are generally used in the wild so don't know if it'd be long enough for field use or not (guessing not, by the length of the keys), but mostly just curious if it can be picked at all at this point.

Re: fas 6890

It is difficult to find the differences between the 68xx/69xx locks. What I found out is:

6580: Double bitted, key retaining, 8 levers, EN1300 Class A.
6804: Single bitted, key retaining, UL 437. Edit: 7 levers, mechanism like in deposit locks series 4110
6805: Single bitted, not key retaining, UL 437. Edit: 7 levers, mechanism like in deposit locks series 4110
6824: Double bitted, key retaining, UL 437. Edit: Perhaps 7 levers
Edit: 6825: Double bitted, not key retaining, Perhaps 7 levers, UL 437.
6860: Double bitted, key retaining, 8 levers, EN1300 Class A. Edit: + 1 back lever spacer
6870: Double bitted, UL 437. Edit: 9 levers, perhaps random lever orientation, key retaining
6880: Double bitted, key retaining, 9 levers, EN1300 Class B.
6890: Double bitted, key retaining, 9 levers, anti-compression, EN1300 Class C.
6980: As 6880, but with anti-x-ray?
6990: Double bitted, key retaining, 9 levers, anti-compression, anti-x-ray, EN1300 Class C.

There are photos of the 6860 at http://wiki.koksa.org/FAS_vds_Klasse1_verstellbar .
Edit: Photos of 6804: viewtopic.php?f=100&t=12009&p=110685#p110685 and pick viewtopic.php?f=39&t=12058&p=111347#p111347

I do know 6860, 6880, 6890, 6990, but I have never seen the others. I can guess that the 680x has all levers on one side. Otherwise I have no idea what the difference is, e.g. of the 6580/6824/6870 to the 6880.
