Question about 2007 Mercedes-Benz CLS500
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

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 also.one 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 fixya.com!

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.

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...
