Ignition lock problem

Suddenly the key will not turn in the ignition lock of my 1997 Disco
TDI. The key goes in freely but refuses to turn, same result with the
key I normally use and the less used spare. Anyone have any ideas?

Inside the barrel of the lock are several small "cylinders". When you push
the key in, these are pushed upwards by an amount proportional to the
corrugation in the key. If the lock gets contaminated, the cylinders, which
are spring loaded, may stick and not slide into the correct position. The
key can only be turned when all these cylinders are in the correct
position. That's the best explanation I can give.

The solution is to soak the lock in WD40 or Plus Gas -- and pray. You could
also apply a little gentle heat (or, better, heat the key) and work the key
backwards and forwards until things become unstuck.

If you attempt to turn the key by force, you will only make matters worse
and could break the key.

It sounds like the barrel has fallen to bits, or possibly the electrical
switch had broken up and janned it. It could also be the steering lock
has jammed - wiggling the steering column may free it up if it's the
latter.

Walk around to the back of the car and carefully check the
registration on the numberpate against the V5 certificate for your
car.

If different, then the car you are trying to start is not yours, and
may have been left on your drive by a passing thief who has made of
with your vehicle, but could come back later to retieve his own car.

or just spray it with lots of fine oil, (though not WD40 which
eventually dries out and goes sticky) seems to be the usual advice.
Graphite powder has also been recommended in the past.

You have tried wiggling the steering wheel at the same times as trying
to turn the key haven't you? If the tyres are holding the steering
against the steering lock you can't turn the key until you release the
pressure...

Oh, have this egg. B-)

No it's not the steering lock. I know what that feels like. And I don't
think the steering lock is actually clicked into engagement because I
left the wheels pointing off centre when I parked. It's almost as if
it's the wrong key, but it isn't.

Thanks for that suggestion. I don't like the idea of using oil. Do you
know where I can get graphite powder?

Not uncommon, sadly.

You either need a new lock (Richard will tell you the prices) or take
yours to a locksmith (a proper one) who may be able to clean and
rebuild it for about 20.

Meantime, it's easy to remove the lock and use the key to turn the
electrical switch (which just plugs on the end of the lock barrel).

I did mine twice, before surrendering to a new lock.

Re: Ignition lock problem

Hello sounds as if one of the pins in the ignition barrel has got stuck so
it would act as if the wrong key was being used, hopr you get it sorted

Fairy Nuff. B-)

If the steering wheel is within 15 degrees or so of the click position
it's easy to move it when climbing in/out/moving around such that it
does click. The wheels don't have to be straight, I've not played with
mine to see if the wheel has to be the right way up or if the lock
will click in at 90 or 180 degrees etc... But no matter a waggle will
free it so it does appear to be a lock failure, tried a few gentle
taps? Might free the stuck pin(s).
