Anybody know any Vauxhall Technicians?

Common issue with the ignition. When you remove the key the radio stays on and when you open the door you get a beeping to remind you the key is still in the ignition, when it's not.
Most threads report the barrel being the issue. I've removed the barrel, cleaned it up as people suggest especially the part at the bottom that moves to determine if the key is in or not.
I would expect when you remove the barrel for the beeping to stop though as the plunger at the bottom of the barrel housing is free to release, which it does. I've used a screwdriver to move the plunger in the housing up and down but this has no effect.
The other thing that could be at fault is the CIM, but I've found no further information on that.
So there are three possible faults
1. Barrel (I think this is OK)
2. Barrel Housing (My thought, but no way of testing further)
3. CIM faulty.
Now I returned from holiday and reconnected the battery today (only way to prevent boot from being opened) and had a further play and the problem was intermittent for a bit but now back to being faulty.
Any help greatly received.

I take it thats its an Astra G or H then ?
Cim modules are very common for throwing up all kinds of unusual faults..
But in this situation it sounds like the microswitch at the bottom of the barrel maybe at fault..This could be built into the CIM,depends on what model and year your car is..
If the car is put onto Tech 2 and sub section of "body" is selected then key position and status can be tracked...Also any CIM module faults will be recorded.

Well looks like mine is the CIM. Changed te barrel housing and problem is still there.
I then played about with the one i removed and found that pins 2 and 5 have continuity when the plunger is pressed down.
So to me that rules out the barrel and housing.
Probably not of any interest but you never know who might find it useful.
Right, I have fixed mine for nothing. Somebody posted on another forum something which at the time I couldn't work out. I was on my way to order a new barrel today but wanted to re check this. Luckily I had a screwdriver with me so could remove the cowl and used my watch pin to release the barrel.
By removing the key by just 5mm (be careful otherwise you can knacker the barrel) I could push the white plunger, but it was a little stiff. Having pressed the plunger in the housing I was guessing it didn't have the power to move it.
So I got home and really gave it a good clean up but no joy.
Then I realized what the person in the other post meant. So I got a 2mm drill and again pulled out the key by 5mm and using a cordless drill and slow speed removed some of the material from the hole in the end of the barrel. After re assembly the plunger moved freely and now it works perfectly. Only a few seconds are required, the drill already just fitted in the hole, so you really are only just tickiling it.
One thing I can also confirm is that if you remove the barrel with the battery connected the bleeping noise will continue, so there is obviously something else the switch at the bottom is working with.
