HU66 Lock Picking Question (Audi A6 '00) - Seems to need Un-picking

[obdsystems]

Still practicing as ever - I've a lock here which picks in 4, 8, 1, 8 but 4 seems to need un-picking after initial slapping - otherwise can't continue to 2nd sequence.

This is only possible with the single lifter so what i'am i doing wrong ???
Any tips ???

Cheers

if having to back pick , you are overlifting the positions that you need to back pick , cant be anything else .

you either have too much tension thus need too much lift pressure resulting in overlifting , or your not controlling your picking pressure to only lift 1 x 1mm increment at a time.

Rapid question for you re a4 08+
my mate was trying to pick one for over 2 hrs without any luck, i have tried my other friend a4 08 plate and gave up after 15 minutes as it was just for training.
but an hour before i done ibiza 12 plate within 2 minutes.
are those a4's more difficult than others?

I have run into the same situation where I feel I have over picked one tumbler. In these cases I use an auto fill program to guess what the over lifted tumbler is. In other cases all tumblers are slappy nothing is over lifted but the cylinder does not turn. Again I use the auto fill in program for all the cuts to confirm its a legitimate code.

I have one BMW practice cylinder that is a bear to turn to the left even after all tumblers are picked, the clutching mechanism on it is extra stiff. Might be a similar problem with Audi, although I have not done Audi in the field.

No problems with audi , A4 or otherwise , ive done plenty of A4 including 14 plate , had a brand new A4 a few weeks ago at the audi delivery yard , i get alot there as delivery drivers are great at locking keys inside, had a 12 plate A5 yesterday and seem to get alot of A4 convertibles with keys in boot.

Alot of the vag problems come from the lock not being used , the lump of grease they put in at manufacture drys out and sets , this jams wafers out of position and holds them there , as does corroded locks and dry locks , meaning wafers sit out of position so are already overlifted , it also hampers feel on the slap you feel for , always flush out a lock and work with a rake to free up wafers .
i got called to an a4 convertible last month where they had a spare unprogrammed key that wouldnt open boot to retrieve main keys , after 15 minutes of flushing and raking the lock was as good as new and key working fine in boot again , everything was siezed and caked with dry grease .

ive been out to quite a few others have failed on , and 9 times out of 10 the dryed out grease is the issue , just a squirt of wd40 is rarely enough , a good flush out and work the wafers to get them moving is essential .

you will get the odd one with a bent wafer where some idiot has over raked it , the odd broken clutch unit , even the odd siezed lock , but on the whole a good flush out and rake cures many issues .
i had one that after flushing and raking , what was left of a spiders body came out on the rake , the body was overlifting .

its always something simple when one plays up , its only hard when you forget and dont run through flushing and the basics first , no vag lock is any harder than the next if everything is clean and lubricated and moving as it should be .

as with anything its all in the preperation , ive had some horrendous locks that worked like new after a good flush and work out on a rake , its the only thing i use an inner groove pick for is to work wafers after and during flushing out .

the older system 1 locks can be alot harder than the newer locks due to wear .

when ever ive looked at a lock someone has had trouble with it has always been something simple , from dry grease , corrosion , too much or too little tension and lack of lock knowledge , 9 times out of 10 its been dry grease or corrosion on vag.

your 12 plate was a newer lock , grease wont have set yet , 08 plate is now 6 years on and i doubt key was ever used in door , id bet it was dry grease or corrosion causing your issues , many say they flush out , but when you chat to them all they have done is spray up with lubricant , which is futile if the lock is full of dry grease and crap . plenty of flushing and use of a rake gently to get each wafer working properly , works wonders.
You will be surprised at the amount of crap that comes out when raking and flushing .

I'll find something useful to rake with - thanks Martin for advice.


Yeah no lock is equal - some definitely seem easier than others!!
With my lock I've found the twin lifter better given gentle pressure on initial picking. Seem to do every time now :)
