your vedio was really helpful but my fuse was absolutely fine but had become loose so just fixed it properly and the lock worked just fine !! Many thanks !! you saved me a trip to the garage !
God bless you brother!! Just got a Mercedes a week ago and this morning had this problem. Wouldn't start. Key wasn't being detected. Found the blown fuse. Replaced it. Back on the road. Hallelujah!! Thank you
I did replace the fuse, but as soon as i put it in, it burns. Amy ideas?
I have a 2005 C230 so same thing is happening to me booth remotes only work when I put the IR at the door handle sensor so I watched your video and effectively the number 8th 7.5 fuse was blown so I replaced it but it keeps blowing the fuse what this could cause it?
haven't done anything to the car everything still oem?
I just replaced the remote battery last month. Last week I started noticing the key doesnt work randomly but when i took out the batteries and put them back in it worked. Today I came home from work, pulled out the key, and tried locking the door, it wouldnt work. Had no problem starting the car when i left work or any other issue. The red light on battery works anytime I click a button. Please help. Car: 2005 C230 Sedan @easysteps
I've looked all over U-Tube trying to find a video on how to remove the 2005 Push to Start shifter. everything works just fine on my clk 500. except for the push to start shifter.
Help please…
My w211 is having the same problem, but it also won't start the car. I replaced both the keyfob and car battery, but no fix. The keyfob light blinks when pressing the buttons, and the cars lights and stereo works fine. I checked the fuse box in the trunk, but none of the fuses are bad or blow. My 8th fuse was actually a 30A fuse, the 9th, however, was 7.5A – neither looked bad.
Any thoughts?
was your car starting up when the doors wouldn't opening or close up
if this will fix my problem tomorrow I will celebrate it
I have this issue.. The second I replace the fuse, it blows…
What if this only occurs intermittently and usually only when it's below freezing outside.
once I open doors with blade key I can start engine with no issues. Or if I press the buttons 10x it eventually opens
Can anyone tell me how the keyless go works? My key fob works perfectly (unlocks, locks, opens trunk, etc.) but I never was able to figure out how keyless go works. Since I got it from the dealer, this has never worked. The way I understand it, I should be able to just walk up to my Benz with keys in my pocket and just be able to push the button on the door handle and it should unlock my doors? Anyone else have this problem? I drive a 2011 C300 Sport.
Any info would be great. Thanks!
I have a 2010 E-350 Coupe with two key fobs. My everyday key fob dropped & stopped working; it wouldn't do anything at all … other than blink red. I've replaced with a new battery and still no action. My secondary key fob works just fine without any issue.
Thanks!
Outstanding dude,it fixed my problem,for months the damn thing would not lock/unlock the…had to go very close to the door sensors but even then I had to use the key most of the times.We all know how hard it is to get that skinny key out and turn it….nightmare. I went to the dealer and considered buying a new key,thinking the one I have must be faulty…you made my day,thank you.
i have a problem of my w211 in close distances open the car in the large distances not open what should i do
hey nice vid, i got a w211 i can start the engine without key but car's doors won't unlock excepted the rear left door or trunk, Windows doesnt open or close nor the wings mirrors, any idea? thx
I can't open the fuse box.
I have a problem with my C200 2016+ that the car just can not find the keys. But, if i put the key in front of menu button at the center of the dashboard, the key is found and everithing works ok… Do you know what can i do to fix this problem ? If i take of the button and insert the key, everithing works perfetly… Can you help me ?
Thanks..Went to the exact same and you helped me Greatly!..Keep it up!
One of my key fobs works, the other doesn't. Tried replacing battery. The one still doesn't work, but the other ones does so it can't be the fuse or the vehicle receiver. What next?
I can't find the fuse panel in the trunk. They have one under the hood on the left side. Is that it? 2006 SLK. Thanks
I have the same problem. I unlocked the car with the keys then I tried to start the car it wouldn't start even though the key was turing all the way. Can you tel if the problem is the fuse?
when this happened to you did you that the remote wasn't working did the car turn on
But when I click the key fob, the car is not responding to it and I cannot start the car.
