[henryd]

if the steering is locked have you tried rocking the steering wheel as you turn the key

[essexgent]

hi yes i have try'd that an still nothing the key refuses to turn the barrel i have even try'd a little bit of wd40 on key

[TheBoy]

I reckon you need to keep trying, removing and reinserting key. Once you have it turned to I, remove the barrel and service it.

[Marks DTM Calib]

Spray a bit of the (over rated) WD40 in to the barrel and leave for a few minutes

Insert and remove the key 10-20 times.

Try again

Oi! It has its uses. Its quite good for bringing plastics back to black

may have some fluff from your pocket in the barrell, try a long needle in the lock, bend the point a bit and push in and out of the barrell see if you can get it out.

I had a similar problem with mine. I resovled it by covering the key in graphite ( rub a pencil lead over fine sandpaper) insert, and withdraw the key several times. Good as gold now.

I had this problem with my old vectra twice  dont use wd40 as this makes all the sliders inside stick, give it a tap lighty with a small hammer if this dont work it means a new barrel the problem is if wont turn then you can not get barrel out call local locksmith they dont charge much mine was about £35 but he will drill it out which means new barrel cost £54,try what cleggy has said better than wd40

[essexgent]

thank you very much lads for all ur help an advice i will try all of these things

From experience, and having refurbished ours after this problem, I'd say just don't bother with the various lubrication ideas, or the hitting with a hammer idea.  Neither helped us.

The problem isn't friction, it's more one of fractional misalignment, or burrs caused by the tumblers hitting bits they shouldn't during previous attempts to turn the key when not fully in etc.
There's near-zero torque required to turn the key if everything's OK with the tumbler alignment, and the tumblers simply have to move when the key's inserted, there's no way they can 'stick'. 

The problem comes through wear on the key, wear on the tumblers' surfaces that touch the key, and the wear/collisions between the outside surfaces of the tumblers and the inside suface of the barrel.

Persist and it will turn, then you can get the guts out, then you can disassemble and refurbish as per the guide.

What are you all doing with your ignition barrels? There's 160 000 miles on my car, so you would expect some wear on the tumblers. But I've never had any problems with mine (touches wood as we speak/type), the same with my 170 000 mile Astra. The only problems I've ever had with either, is that the Astra woudn't give you the key when you turned the ignition off - but PTFE spray seems to have sorted it.
I'd say that lub WILL help. There are some very very tiny springs inside the barrel that lift each individual brass tumbler back to its rest position, if the grease in there has solidified, then the spring won't be able to return the tumbler to its start postion and may allow the tumbler to foul the key on removal/insertion.
Assuming you get the key to turn at some stage, I would remove the barrel & clean the whole thing up .... make sure you keep it all in order

had the same problem  kept trying and eventually turned ,dont risk using after having turned, I fitted a new barrel straight away.

i just had this problem 2 hours ago.. i used a brake cleaner spray and sprayed inside the ignition until no more black stuff came out. carefull to put some wipes just below the ignition not to damage anything. i inserted the key a few times and sprayed again and after i thought it was clean i left it for 15 minutes to dry, then sprayed some wd40 and turned the key on and off untill it started to work smooth.

i don't know if it is the best way to do it and how much it will last but at least you won't be stuck somewhere because you can't turn the key. i will give feedback tomorow if it needs lubricating again or not .
