I did a search and I found an '05 thread about someone getting there key stuck in their ignition and turned out he just had to shift the gear selector around to get it out. This was the closest thread I found to getting help, so I had to post:

I have an 87 N/A, and when I turn the car "off" and take the key out, it still runs. I had to put it in gear and stall to shut it off. There was an alarm on the car but it has been disabled and I removed the wiring as well, I also tried tapping the brake when I removed the key and it doesn't shut off, which is a feature of remote starters...since I wasn't sure if it was just an alarm on tere or an alarm/starter. What I want to know is what the problem could be, and if it can be fixed replacing the part where I insert the key. I can get my hands on another one, but, if this is what I have to do then could someone point me to where I can find a diy or step-by-step in removing this piece?

If worse comes to worse I know a mechanic I can get to check it out, but he isn't a supra expert like some people on here and furthermore I wanted to get it dones this weekend and he won't be able to come by this weekend.

Thanks for the help in advance everyone, if I made a mistake in posting please point it out, I've read the rules and tried to get familiar with them and am sure I'm not breaking any of them. Once again, Thanks! :1zhelp:

Well at least you searched first before posting so you should have some one on here that can help you. I don't know what the problem is unless it's in your ignition. I"ve heard that they go bad after a while and was told to keep mine from my front clip in case mine went bad. Have someone check that out. Good luck, and I wish I was more help........Jay

Has the aftermarket alarm been completely removed? Two other places where the disable wire for turbo timers and remote start systems are often located are the clutch starter switch and the e-brake switch.

It does sound like an ignition switch problem. Don't see that much in Toyota's, but Fords and Chevy's do that alot. As far as getting it out, I havent done one in a Supra yet, but I can check it out on my parts car tomarrow.... hopefully I remember....

Cuel: Thanks in advance if you could give me an idea cuz I don't really know what I'm doing with the ignition switch and I got as far as taking off the plastic around it only. I don't really mind calling the mechanic but learning how to do it and getting the experience is something I want too.

CRE/CryoSlash:As for the turbo timer, I'm still goin to check it out tomorrow even though the car is n/a, cuz the alarm that was in there may have had the function and a previous owner may have activated it not knowing what it was or simply by accident....although the car still stays on when I tap the brake. It seems like a silly idea even to me but hey, it's worth checking out when to test it, it's as simple as removing the key and waiting a few minutes.

If not, I don't look forward to doing the ignition switch replacement, (but I may anyhow).

In a somewhat related note ^: The door look cylinder's seem to be seized and the doors don't lock (the passenger side may) but I know for sure the driver's side doesn't. The guy I bought it off of said it wasn't a problem for him since he used a key fob to open and close it, which quite possibly the previous owner(s) may have did as well causing it to seize. So...when I change the door locks, I know I can get my hands on two doors with working locks, the matching ignition and I think trunk key hole as well, so if I use the locks from this set I'm gonna have to change the ignition switch anyways to avooid using two different keys....one to open the car and one to start...(ghetto).

Cryo: I live between bramalea/sandalwood and dixie/sandalwood. For easier reference I live near trinity commons mall, or about 10 minutes from bramalea city centre, I'm not sure if you're familiar with these malls or the area. I got some pics of the car how I got it on a camera, I haven't loaded on the computer yet and when I do (2morrow) I'll let you know and send em, jus pm me your e-mail and I'll send em there. Only things I changed on the car so far: (I hope I don't get too off topic :icon_conf )

Bent hood (with a kink) -> replaced with a good hood, also front upper bumper piece soon.
Interior had some miscellaneous grey pieces, changed them to burgundy to match the interior, seatbelts still left to change to burgundy.
Had leather seats, back and front, and 2 leather inserts, I put in 2 cloth ones.
Need to change the starter, probably 2morrow.
That's about it for now, f***ing rims ar cracked...but they have all wheel lock nuts, and nowhere has the lock nut remover in stock or on order, workin on getting those shit off. Trying some hex keys 2morrow, hoping on a 12mm to fit.
Also, I'm planning to make my supra look just like the one in your sig, which can I assume is yours? lol except maybe with the exception of the black lip. Looks nice and clean.

Anyways, 3:09 and I should get some rest, I wanna get up early, head out and do some stuff, and work on the car a bit before I lose the light. Take it easy guys and thanks for the help. I'd love to figure out if there was a way to fix the issue without removing the ignition even though I may have to replace it anyways, so I guess now it comes down to if anyone could give me kind of a diy write up to remove it so I can replace it, or point me to one. I'm gonna google it a bit before I sleep. Later guys.

If it just keeps running for a certain period and that period of time is consistent it's probably not the ignition. Also, keep in mind that while the previous owner may have activated a shutdown timer in the alarm or added a turbo timer to the car doesn't they wired it properly, they may not have connected the disable line.

That's a good point, they may have installed/had it installed incorrectly. Thanks.

Sorry, forgot to take my camera today. Just put it in my car so I'll remember tomarrow. The ignition switch that I'm talking about isn't the part the key goes in, but the electric part behind it (on most cars its seperate). It should have a connector from the harness under the dash plugged into it. Usually, it gets corroded inside over time. It's the part that would need to be replaced.
Really hate to disagree with you CRE, but this sounds alot like an ignition switch problem. I'd double check the after market alarm, and make sure you got everything out, and got all the ignition wires reinstalled correctly... just in case.

I didnt bother to test it (alarm) because I'm gonna change the ignition, the part where the key goes in and I'm not sure but according to you maybe the part you mentioed, behind it. I need to find out what I'm doung first, I wanna learn how to do this get familar wit my supra and stuff like that, I aint letting this baby go!

The only regret I'm going to have is....well, I wont have enough right away to paint the car and it may have some different colored exterior parts (i.e. hatch and hood, maybe more) and driving the supra like that is gonna make not jus me but the car look bad.

P.S. I got some free lowering springs, two of which I installed and is taking longer than expected, nothing out of the odinary occurring, jus having issues aligning the shock mounts properly and the bottom bolt with the bushing, so it's taking time. So right now the back of the car is lowered and front is stock height, lol.

Shit I write long posts, of pure nothing, fuck Imma go watch some tv or some other shit. I'll be on later...browse around

P.S.S if anyone with some adavanced expertise with regards to the mk3 supra has any helpful beginner info that isn't commonly known that may help me in the future... u know, just some hints or tips, I'd appreciate em.

Cuel, I don't think we're disagreeing. I think he should check the ignition. I merely added that if it's staying on for the exact amount of time, every time, it's unlikely it's the ignition. I've been through what you're referring to and seen it on other people vehicles. It's definitely a possibility, but I've never seen one that caused the car to continue running for a precise period of time, every time... all the cases I've seen (only 5, I'm sure you've seen more) were far more random than that.

If I'm wrong that's cool, you're the professional mechanic, not me.




EDIT: Guyana00, Are you aware of the online Toyota Service Manual (TSRM) and Toyota Electrical & Wiring Diagrams (TEWD)?

I seem to be missing where he said it stays on a specific amount of time? I thought it just stayed on till he stalled it... that's why I think its the switch. It is rare that I see this in a Toyota, but it does happen. Lol, and I don't call myself a professional, I'm still learning... :)

I stated that qualifier in my post:

CRE said:

Just trying to make sure all the bases are covered, he never did say if that was the case and I never said that it's absolutely not the ignition switch. I only gave him a means of determining what to check first.

Oh, and he said if he waits a few minutes it turns off.

No sweat, the best are ALWAYS "still learning". ;)

It's all good, I could have been clearer.

Yeah, the switch isn't hard to pull, unlike some cars I've owned.

Cuel, you get a chance to upload the pics to ur pc yet? if you dont wanna post here you could e-mail it to me although I'm sure everyone would love a write-up. You could even post it in this forum as a new thread, may get moved to tech-tips or stickied somewhere. Thanks btw.

CRE, yes thanks, I'm aware of the online TSRM and I just recently found out how to use the diagnosis box to read codes from the engine light. I'll see what it tells me, if it tells me anything. I'm aware of the TSRM like I said but as a matter of fact I'm new to it so I'm not very familiar with it at all. Thanks.

Take it easy guys.

It's pretty easy once you have the covers off. On the back of the ignition, you'll see a white plastic piece with wires going to it(its the ignition switch). Trace those back to the black connector, and unplug it. There's one screw on the bottom of the switch holding it to the tumbler. Undo that screw, and you got it. There's another wire taped to the switch harness. It goes up to the side of the tumbler assembly. Just cut the tape and leave that one where it is. Pretty easy really.
