Mercedes 2007-2008 C300 crank but don't start easy fix

When your car crank but doesn't start, the problem might be the ship in your key is not communicating with the car to make it start. This problem might be because of:
a low battery which needs to be changed
bad electric circuit in the key due to water our humidity
Solution put the key in place and click the open button on the key and start the car and it might start as when u push the button while starting it you communicate with the car and the chip is recognized

This actually worked. My mom’s C300 sat for weeks because no one could figure out what was wrong. The car fired up right up when I tried this. Thank you!

Wow! I have a 2008 manual trans c300- with a beat up key fob! Car wouldn't crank this morning, I tried this after watching the video, and it cranked right up! Thank you! Time for a new fob!

It even worked with Mercedes C 250 2013 . Thank you life saver

[@icarti2x146]

Yea bro this actually worked fr fr my 2009 c300 has been sitting for 4 weeks because it needed a new fuel pump n and a new pump module after the fix my car ran fine but the day after my car didn’t turn on, I was done but I came across this video and saved me from getting stranded and walking home

[@nikolaigordon5961]

Worked on my 2004 clk, unbelievable saved me getting recovered at work. Thank you

[@sandraani9755]

Thank you so much for the helpful tips. Watched several videos on fixing this problem nor worked until I tried your tip!Thank God I found your video which did the trick on one trial., hence prompting me to cancel towing my car to a mechanic

[@Bbynessb]

YESSSSSS! I watched so many videos & they all seemed so complicated, most of them seemed like they were for mechanics or men who know about cars and have all the tools lol I watched your video and ran out to see if it worked and IT DID! Thank u so much for posting videos like this!

You saved our day thanks it worked

My R350 will crank but wont start. I tried this method and seemed like the current was stronger but still didn't start. I just changed the battery on my started and will try this again later. Hopefully my car will start 🙏🏼. Video was helpful though. Thx

Hi, for this exact same vehicle I have a major issue 1 : after doing an online programing of the ecu and front and rear sam , it suddenly says hood sensor no com and back seat rest latch code comes on ( previously before the online programing no such issue and even the car hood doesn't seem to have Been equipped with any sensor for hood warning for my 2009 w204 ) 2: I try to activate the teach in drive authorization and when it gets to the part when it says start engine and allow to idle for 30secs , the Benz won't start until I turn the key(ignition) back off and try to start it again before the engine will start which at this time the process fails , I'm using the launch immo elite , also launch pad vii and topdon phoenix plus , yet no success, please I really need your help

[@dques]

Cool video!! Thanks 🙏 My daughter and I had cranking, but no starting last night on her 2000 s500 for like fifteen minutes. Hopefully this trick will get me out of a bind if it happens again. Do you have a video on how to change the batteries on the key?

[@do-iturself]

tomorrow will make a video how to change the battery on these keys... for my car i ordered a new one as when i changed the battery the range of the remote key became short.

[@dques]

@@do-iturself I will look forward to the video. Unfortunately this is not the problem this time as the car stalled out while reversing into my parking spot. I was able to push it the rest of the way, but then it just cranked trying to start it. I don’t know if it’s that crankshaft position sensor; that doesn’t seem like something that would make it stall out. Thanks for your video.

[@do-iturself]

@@dques yes if crankshaft sensor got bad car wont start.

[@godspowergodwin2537]

@@dques hello Were u able to fix your car, if yes please how did you get it done?

[@stanceworks7995]

car was working fine, stopped at shop and when I got back in it did not want to start. Key turns, lights are all working. But car wont start. Tow truck says battery is showing that it is fine with the voltage. I tried this trick but did not work for me. As I turned the key I pushed the lock button and turning at same time but did not work for me. I don't know what else it could be as the car was working just fine 10min ago

[@unknownuser6548]

is it basically the lock button that I am pushing?
