Hot ignition and key

Sometimes when I turn my car off and remove the key it's hot to the touch; so is the ignition itself. It's not from sitting in the sun. Electrical problem??

Yes, it sounds like an electrical problem to me. Hope it doesn't get too hot and melt something.

M 1988 Ford F-150 truck wont start. I just get a single faint click noise from the starter area plus when I turn the key to the run position the cables and solenoid get extremely hot.


My thought is why the cables get so hot when you just turn the key to run. It makes me think you may have a short. The cable you said might be touching the header can you get a piece of rubber or plastic between the possible connection. I have had cables be bad before I do not remember them being hot but if enough broke wires were arcing in the cable I guess it could cause the cable to be hot but I only see that when you try to crank the truck.

Bypassing ignition


You take the hot wire to the ignition switch and twist it together with the run wire out of the switch-then ignition is on, just as if the key were turned to on. Then take the start wire that goes out of the switch and touch it to the hot wire to make the starter work. Soon as engine is started, remove the start wire from hot wire and tuck it out of the way. When you want it off, untwist the hot wire and the run wire.
If you cannot hot wire it like this, check if there is a security system that has immobilized the car. I don't know if a '92 had a security system.

The engine in my 1984 firebird wont stop turning over after key release


If you are talking about engine cranking, then you should check for free operation of the starter motor solenoid. This is situated on the top/side of the motor and it\'s job is to engage the starter motor only when the ignition key is turned to the crank position. It is plausible that the solenoid has become corroded, or fused in the closed circuit position.
To check to see if this is the case, remove and clean the starter motor solenoid, and test it\'s operation while off the car.


If you are talking about continuous running, not cranking, then you will best use an endoscope and insert it into the engine\'s cylinders to view the innards. You are looking for a build up of carbon on either the valves, valve stems (when in the open position), pistons, and cylinder head. Also check the condition of the spark plugs for a build up of carbon.
Carbon is a byproduct of combustion, and can build up on some internal engine surfaces. This can cause a number of issues when running. The carbon becomes red hot and can retain it\'s temperature for a long period of time. When you turn off the engine in a carburetor vehicle, then air and fuel can still be drawn into the engine while its momentum winds down. However as the red hot carbon in the cylinders is hot enough to ignite the fuel and air mixture, the engine still runs, still turns and continues to suck in more air and fuel mixture, and continues to operate.
It may operate quite roughly and eventually stall out, as the fuel/air mixture isn\'t as efficiently burned when ignited by hot spots, and the hot spots may eventually cool enough to fail as an ignition source.


These two above examples are perhaps a couple of the most common reasons for an engine continuing to run after the ignition key has been turned to the off position, or has even been removed from the lock/barrel.
The only final reason for the engine managing to keep running after the key has been removed, is a faulty ignition lock/barrel mechanism.

My son was playing radio , now my keys are stuck in the ignition and all the power system is shut off. i started the car by jump start but all the power system is not working and the keys are still stuck...


When the PASS-Key® III system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems.

I suggest check in this link the 2007 SAAB 9-7X - Owners Manual, section THEFT and PASSLOCK SYSTEMS (page 90 and next).

Keep us updated.

Looking for instructions to bypass, remove,disable the passlock anti theft system in my 1998 gmc safari, so I can start and run the darn thing.


Your problem may be a bad ignition lock switch it is a common problem usually caused by worn ignition keys. I would get a new key and see if that don't solve your problem. If that don't work then you need to replace the lock itself they have a security feature built in them that won't allow the car to start unless the proper key is installed (sometimes a new key works) this prevent thieves from taking your car by using a screwdriver or by hot wiring ...This security feature is in the lock itself not in the key GM did put it in the key but not for your vehicle

Key hot when removed form the ignition


I purchased a 2010 Corolla in Jul\t 2009. For two months, several times, the key was hot when I removed it from the ignition. I was told it was due to the Immobilizer chip in the handle. I'm concerned as it happened again in Sept 2010. and if it does this periodically I feel in time it could cause a dangerous problem as cars have caught fire due to ignition problems. What response did you get from your dealer or how did you sove your problem??

Wire on ignition switch is hot to touch. will not


Possible ignition switch is not able to carry over 12 volts to starter solenoid on the wall. Measure using voltmeter, power coming in to small wire on starter solenoid. Should read battery voltage. If not, ignition switch may be shorting out.

96 NISSAN MAXIMA SHUTS OFF UPON DECELLERATION OR WHEN STOPPED


Check to see if the floor on the passanger side is wet. If so, than your A/C drain clogged up and your ECM/computer got flodded by water causing all sorts of funky stuff happening. Right next to the gas pedal is a small cover attached to the computer. It has a clip in it. Remove the clip and tug on the cover. Look at the top of the computer to see if its rusted up. Remove the other side cover also, which is on passanger side floor next to your left foot(if you sitting in passenger seat). and check other side of ECM/computer. Check the ECM for rust on top.
If ALL of that looks OK, than I would replace the switch,(since you are telling me that the key got VERY hot) that is mounted on the back of the ignition cylinder. Its a white round switch that failes after a while especially car beeing 1996, just think about how many times that ignition has been turned ON/OFF since 1996. The mechanism in the switch failes, causing starting issues and funky electrical issues.
Does the car have a remote starter installed?? Or didi it have one in the past?? I have seen companies that install them cause some damage to the harnesses on the switch that is mounted to the back of the igniton cylinder. They use "scotch locks" to connect the remote starter and after a while the connection corrode and cause problems too.
Anyways, check the computer for rust first. Than I would install that switch on back of the igniton. You can buy the switch seperately. You dont need the whole ignition assembly/switch only. Switch is pretty cheap (approx $50 ?). Try that and post results. I would feel pretty good about the switch beeing faulty. I have ssen them fail in the past and that's where your power comes into for the starter circuit.(key getting HOT, switch shorting out, making the key hot and starting the car without the key)
