[s-cars] C4 chassis remote lock help

[Tom Mullane]

Larry, I just went through some of this with my 95.5 and my A6.  Got plenty
of replies here and was able to figure it out.
 
The 95.5 is different from the earlier cars - there is a different procedure
for programming the keys.  If you ask at Audi, tell them your car is a 1996
A6; it's just easier than trying to educate them.

This is well documented in the archives, but it's easier to just write them
out than to look them up:
1.Open the driver's door.
2.Take one key and turn on the ignition.
3.Close the driver's door.
4.Lock the car with a second key.
5.Push down both buttons of the remote and hold them.
6.The lights will flash and the car will unlock.
7.Open the driver's door.
8.Remove the key from the ignition.

If you are programming several remotes, I have had the best success by
programming them all at once:
When the first remote synchronizes and the doors unlock in step 6, return to
step 4 and program the second remote.

The first remote programmed will automagically be associated with seat
memory position 1, the second key with 2, etc.  In my case, this is fine for
the S6, for which my wife and I each have separate remotes, but for my A6 I
have one remote and do not want it associated with any seat positions; this
car is driven by 5 or 6 different people.  It is my guess that if you turn
the memory seat off while programming the fob, it will not associate.  I
have not had the time to figure this out on the A6, but I will post when I
do.

As for the key/lock problem, it's probably just lack of use and you have the
right plan of attack.  The trunk may be an exception.  If you are using the
valet key (a bit fatter than the regular key) you will not be able to get it
in.  The dealer can cut you a new key by the VIN of the car.  They will tell
you that they can't, because this was not available until 1996.  Show them
the key and ask them to try.  The "cheap" key is about 60 bucks.

Hello,

Looking for collective list wisdom on some lock issues on my
new to me 95.5 S6.

The remote locking (radio type, two button) had been working
with the car correctly until this past Friday where it simply failed
to lock the car. I locked the car manually (pushing the plungers,
didn't know about the power lock toggle on the driver's door
until later) and noted that the trunk did NOT lock, apparently
correct if I pushed plungers. I guess I expected things to work
like my 200Q (1.8 bar, H+R's, still for sale), so I was surprised
that pushing the driver's plunger didn't work the power locks. 
I assumed the remote's battery had failed, and had to wait until
after work to get a new one, once I got home to find out what
the battery was (2032 CR Lithium, in case anyone wants to know)
as there were no tools at work.

Later, upon getting home, I locked the car using the passenger's
plunger, trunk was open at the time. When I closed the trunk,
the alarm armed. It was then I noticed the first problem.

1.         Has anyone with a C4 car had great difficulty getting the key
            into the lock cylinders? Is this just a lack of use issue, or
a
            central lock issue (would be interesting if the car can
prevent
            the key being used if the alarm is set off. Super Security),
or 
            perhaps possible vandalism. I finally got the driver's and 
            passenger's doors locks to accept and turn with the key, but
            it took a lot of forcing, scraping with a pick and lube to
get
            things to work. I STILL can't get a key into the trunk past
            halfway. I have noted the storm flap over the key hole
doesn't
            appear to be there. I did scrape out some dried looking grey
            stuff, but the feeling of the key being blocked felt more 
            mechanical rather than dirt or worse still, super glue....   

            Note, the keys for this car are the internal cut kind.
2.        The second problem is, even with the new battery, the remote
           seems to have absolutely no effect. It doesn't activate the
locks,
           the alarm, nor do any lights flash in response. The alarm does

           arm now that I have the keys working to lock the car. 

Things I did to reset the remote:

1.        Totally disconnected the battery for close to ten minutes. No
effect.
2.        Taka M used VAG-COM to pull codes on the car. There apparently
                are either no codes w/rt the central locking, or there is
no way for
                VAG-COM to access central locking.
3.        I tried Fred Munro's procedure to resynch the alarm and the
remote.
                No effect, mostly because the remote seems to be doing
nothing. 
                (at least I think it's doing nothing).

Anyone have any ideas what to do next to:
        Activate the remote?
        Access the trunk lock?

TIA, sorry for the long post.
