The parts inside the ignition can be corroding. Solution Spray some WD-40 in there if that doesn't work you may need a new ignition. Keys can wear down and cause this problem, you may want to try a new key before replacing the ignition switch.
Both cars should have same kind of engine: either 4 cylinder or 6 cylinder.
Your ignition key may be too worn down, the car dealership can probably make you a new one. Another cause may be worn lock cylinder parts (springs, etc.) or there could be dirt/sand in the cylinder.
There is likely a crack in the engine block.
Many Camry models have so called daylight headlights.
Something you might try is turning the steering wheel slightly before turning the key. The locking mechanism that keeps the wheel from turning if the ignition is off sometimes puts pressure on the cylinder so that the key won't turn, and pulling the wheel to one direction or the other may help relieve that pressure.
So it would seem. If the ignition is in the column it may also be jammed by the steering wheel lock. Try turning the steering wheel and holding it while turning the ignition key.
There are multiple reasons. One of them is a bad power steering pump. Then, steering system. But it's better to start from joins.
You can replace a four-cylinder Toyota Camry engine with a six-cylinder engine. You will need to purchase a motor mount adapter kit. There will be an extensive amount of work.
I would have the ignition itself replaced. These go out all the time and will leave you stranded. Get a new ignition keyed to your current key and you won't have to do programming. A locksmith can do this for you. Do it soon though before it stops turning.
If the cigarette lighter would normally work without turning on the ignition, yes.
Not quite sure what you mean, sometimes the lock tumbler that you put the key in and turn is called an ignition lock cylinder, if not that, I've no clue what you're talking about? Perhaps you could use it in a sentence or be a little more descriptive. If you reverse the words to Cylinder ignition, that would be when the fuel mixture is ignited by the spark plug.
If you have a 4cylinder not alot. But if you have a 6 then you can cry the blues like me. A least $1300 dollars.
