Key removed, but V70XC thinks key is still in ignition

Post by Ringo » Fri Nov 17, 2017 12:46 pm

I've been having issues with my 1999 v70 XC and the ignition. I see a lot of forum posts about the key being stuck in the ignition and the solution being that the shiftlock overide button next the the shifter is stuck in (in the ON position). In my case, the key comes out of the ignition but the car acts like the key is still in the ignition. I have generously sprayed silicone into the ignition slot and worked the key in and out etc. I also opened up the center console and pulled the shiftlock overide button out and cleaned it well and lubed it with silicone so it and the cable beneath will slide freely. Pulling that button made the shifter lock, where before it would move freely when the key was off and removed.

However, my troubles persist. Currently I am able to freely turn the ignition key backwards, past the 0 stop on the ignition immobilizer ring. I can turn it in a complete 360. The ignition functions fine to turn the car to ON and crank and start.

I can also remove the key from the ignition but the car seems to behave as though the key is still in the slot such as:
1) With key in ignition or without the key, when I open the driver door, the door chime sounds until the door is closed.
2) I cannot use the "lock all doors" buttons- the doors lock and then automatically unlock immediately.
3) My key fob buttons will not work at all (it worked perfectly fine before).
4) The only way to lock the doors is with the key, from outside the drivers door.

I live in a city and park on the street so the key fob is a big convenience when I have my dogs on leashes and don't want to stand in the traffic lane unlocking the driver door with the key.

Any thoughts?

I would suspect the electrical portion of the switch is toast. Easy to replace once the plastic is removed from the steering column.

That's a relatively easy job to pull off. There is 2-3 torx underneath the steering wheel that need to be removed. Once those are out the plastic separates into two halves. Pull the steering wheel towards you as far as the travel will go and they should come out. The ignition switch comes out with two bolts. The replacement bolts on mine were longer than the original ones. Check for your chassis number as I believe there is a possibility of two different ignition switches used on our year. One uses round pin connectors similar to the older models, where as the newer style uses flat blades.

Thanks folks.
So is this where the ignition senses if a key has been inserted? Do you think replacing this electrical portion affect the key rotating 360 deg. (backwards) in the ignition?

I am all for easy fixes and the new ignition switch for my chassis # is part 9447804 for about $60. Is there a way to test the old part to see if it is the problem?

1. Yes, when you look at the electrical portion of the switch there is a pin in the center that is depressed when the key is inserted. If this becomes lodged in, it will act as if a key is always in the ignition. Look at the 2nd picture at this link for what I'm talking about. http://www.rockauto.com/en/moreinfo.php ... 26&jsn=388

2. I doubt it, it is only plastic and copper/brass - with enough effort, it can be chewed up. My belief is the mechanical locking portion handles this and wears away after some years.

Make sure to verify your chassis number. There is two switches possible - they aren't compatible with one another.

Thanks wizechatmgr, I appreciate you for taking the time to explain about the pin in the center. And I see a video by Robert DIY that shows how to replace one in an 850. In my case the key works great for starting it and I've never had the stuck key problems many people have described. It's *just* that it is not sensing that the key has been removed.

One more question for you...as I am trying to keep costs extra low, would dislodging and/or lubing that pin be a sensible fix for the near future?

The problem is you have to pull the steering column apart to really get to it to do that. Whatever you do, don't use graphite - it is electrically conductive...

If you have the $$$ to do it, I'd just replace it, since it is already sticking, it will be sticking again soon. Figure it is at least 19 years old, tens of thousands of key on/off cycles. In my case, it was somewhere around 33k key on/off cycles according to VIDA. If you choose to get a used one, make sure you get the machine screws that hold it in.

PM me your chassis number, I have an old one that has been disassembled and put back together that may have a bit more life in it than your existing one.

Remember, the electrical portion of the switch has nothing to do with the key. It is on the left side of the steering column. Replacing the keyed lock is a different problem.

My problem is in the sensing of the key, are you saying this won't work?

The electrical portion is attached to the back of the ignition key portion and has a plastic connector that slots into the electrical part. The sensor is in the other piece the key fits into. That is a much more challenging part to swap out. The antenna ring around where you insert the key is what senses the key chip. Normally when that fails the antenna ring will prevent the car running, not allow the engine to stay running. I would suggest the issue is the electrical portion having a short in it and is not related to the key at all. You could clean the antenna ring contacts with contact cleaner, but resist trying to remove it as it has a flimsy clip on the front of the ring that holds it in place and that can break off. If that happens it will still work.
