I would try a different key, the Immobilizer on the Mercedes is reading the key and if your key is defective, they trying a different key may be your best options. Other options to try would be to Lock and Unlock the car with the Remote and then try and starting the car. If the above options do not work, then you are well past what you can do without the proper scanners and must bring it to the dealership and you will be in for a $500 - $2000 bill.

Sorry for the bad info

Sounds like a starter to me. Pull it and take it to parts house for bench test. Do not replace unless they say it is bad.

SOURCE: key stuck in ignition but it will turn, and

you most likely have a bad key switch cylinder assembly. you can try to spray wd40 solvent into the switch before you have the switch replaced,but sometimes it's a switch replacement that repairs the problem. have you inspected your ignition key to look for damage to the key itself? try a spare key to make sure it's the key,and not the key switch. you can also try turning the key while turning the steering wheel at the same time to get the key to work.sometimes the switch locks when parked in a bind,such as on a hill,or against a curb and so on. try this 1st before you have the ignition switch replaced. AAA auto club,if you're a member covers part of the replacement costs for a replacement switch also. you may have coverage through a cell phone more thing to try, if you have a tilt steering column,try to reposition the steering wheel to see if you can get the key to turn. remember never force it enough to break your key off into the switch! thank you for choosing!

Ignition relay or fuse could be the problem. When you turn the key to start do you hear a fuel pump kicking on and or do you have spark when you hot wire the starter (I know it's hard to check while trying to start it)? You can email me back and I might be able to pinpoint it more.

SOURCE: Windows won't go up our down power door locks

My first concern is that if these things are all just now happening at once, your battery may have become so weak, it's just unable to fulfill your request...

I would highly recommend checking all your fueses as well as any Maxi fuses under the hood, not just the fuses panels under the dash... If your'e lucky a fuse may be sitting tilted in the socket or simply burning out.

It could be helpful to know if anything has been done to alter teh cars wiring, such as a new stereo or speakers or amplifier being installed as it may have been done improperly. That is to say if this is a recent problem that has begun to happen, or each of these things have been going out for awhile...

I'm sure many will suggest you may have a short in your wiring... That may be true and can be a long tedious task to track down and isolate...

So, I strongly urge you to consider a NEW BATTERY. Clean Battery Cables, making sure there is no corrosion (That could cause all these things) And be sure to check all fuses. That means pulling them and visially inspecting them to make sure they are not burnt or broken.

On that note, I have replaced fuses that looked fine and the problems went away... Keep in mind how some if not many or even all of those are possibly 10 years old... They are a cheap fix... Even if you replaced each and everyone.

If you have a Keyfob that is not unlocking, locking arming the car whatever, Consider also changing the battery in it at a minimum of once a year. I think it is recommended every 6 months. But that is usually dependant on use.

If all the fuses are good and you have installed a new battery and these things are not working, you could be looking at the actual window lift motor going out and even the door lock switch burning out. Some things you can have tested and others are typically cheap enough to replace. But I would investigate looking into these, having them tested, prior to chasing a fantom wire short, which may or may not be present at all...

Even buying a second hand part at a U-pull it can be quicker, cheaper and easier verification process than chasing a short which may not be...

Good Luck to you and Happy Motoring...

My 2008 silverado won't start battery is charged

No, it isn't an ignition issue.

Check power to the starter motor solenoid.
If this is getting power when cranking, then the issue is with the starter motor solenoid or starter motor. Replace.

Car won't start, seems to have power, all lights working. when I turn the key nothing happens. this only happens sometimes

Could be a bad alternator.. It may not be holding charge. Or your starter could have failed.

Though I've had the same problem and it was a dead battery in my vehicle. Had enough power, but to keep the car on..

Dodge Grand Caravan won't start. Replaced ignition and starter tested fine but when I turn key and nothing happens

Check the neutral safety switch on the transmission. It should have three wires on the connector (if I remember correctly). There should be power on the Brown with yellow wire with the key in the crank position. If there is ground that wire and see if the van starts. If it does replace the switch. If it does not check the starter relay. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

2009 HHR won't start. Battery is good.

Is the security light on or blinking?If not then do you have power to the starter.You can check this with a test light.You should have power when you turn the key to start.The test light should light up.Should be the small wire.I believe it is purple in color.If the security light is on then you will have to get the codes to see what is causing the no start.Hope this helps.Good luck.
