Ignition Lock or Shift Lock

2019 Silverado Custom.  When turning off the engine, my ignition key will not come out of the lock cylinder, more often than not.  I have removed the cylinder and cleaned and lubricated it.  It works perfectly while held in my hand.  Upon installation it still hangs up.  Today I discovered that once it is free to come out, it is fine until the engine is started and the vehicle has been put into gear.  Then when turned off it can be cycled to the removal position, but won't actually come out.

 

After much experimenting, I found that if I turned the key toward start, to the point where it pops out a bit, and then back to remove, it will come out.

 

Any help would be appreciated.  I am leaning toward it being related to the auto transmission shifter, but I don't know what I'm looking for, and can't find any late model info anywhere.  Wiggling the shift arm, or the steering wheel has no effect at all.

 

Thanks in advance.

I would think it's the steering lock that is causing the issue. I don't believe you can turn it if it is not in park or neutral. I know I've had several vehicles that if the steering is in the right spot it locks and won't let the key release. I've had to pull hard on one side or the other to release the pressure for the key to fully release.

Thanks for commenting.

 

I've tried all the usual stuff.  The reason I think it is related to the steering lock is this.  Once it is free and comes out, it will do it over and over again.  It's not until the engine is started, and put into gear, then put into park, that it happens.  I can't find any information on what/where/how the locking mechanism works.  If it is a function of the lock cylinder, then buying a new one should fix it.  But I'd hate to spend around $140 for a new one, and it not be the problem.

Hi Don

I am running into the same problem with the key not turning all the way back to pull out the key. What was the cause. Thanks

Hi Joe.

It is a bit unresolved, only because my friend won't make the time for me to finish up the project.  There is a locking module in the steering column that senses when the vehicle is in Park and releases the key.  Otherwise it's stuck.  I unplugged it, and now he can take the key out while driving down the road.  LOL  He's a bit tight about money, so I didn't want to spend the money on the part, without putting a meter on the disconnected line to determine if it was actually getting power or losing power when the shifter is in park.  I didn't think of it at the time.  I'd hate to replace it, which is easy, without making sure it wasn't a problem further down the the line.  I have attached the parts diagram from Chevy.  As I recall it is part number 9.

Having the exact issue you described with a 2021 chevy trail boss.  what part did you unplug off part # 9? I have been to the chevy dealer 3 time with no resolve.  I would love to try to unhook this to try.

 

Thank you

If yours is the same as mine(2022 Chevy 3500) then it's the very front of the cylinder housing. Right by where you'd put the key in. Its a 2 wire. Once that's removed, they key will come out regardless of what position the shifter is in. Good luck.

Had the same issue with my 2021 Silverado Custom. Replaced the part number 84990323, about $70 on Amazon, and it fixed it. It’s the ignition and start switch housing. I let it run for a minute and replicated the issue and started pulling apart and reconnecting wire connectors one by one and that one released the key. Hope this helps!

Thanks for the reply. I was planning to get that and just try since it’s cheap but haven’t had time. I just ordered one and will try that out!

It did not fix mine. Still have to let the truck sit for about 5 mins before it will let the key out.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      2027 GMC Sierra: Official Discussion

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
