[@atomattic1]

If you change this fuse or it is ok and you still do not have communication with smart key and will not start. Try putting 12V to that fuse directly. If all works ok after that, you have a shorted wire to that fuse. One common problem connection that goes to the back of the car. It is beneath the carpet on front passenger side where this fuse gets its power. Lift carpet from passenger floor all the way to front of front passenger seat. Its not where all the connections are where module is at fire wall. it is roughly 8" back from there, and to the right center of the seat. About 6 wires connect there. Its a thick gauge red wire connection that powers that fuse. That usually has the problem lays. Good luck Keep in mind, not all W220's have this right side fuse box. I believe, is on 2004 and up.

Do you have your car battery connected to a float charger? If yes, disconnect before pressing any remote buttons. Also, leave car unlocked when float charging. I'm not sure what else could cause the fuse to pop. For sure there's a short somewhere that's causing that. Make sure that fuse is snug in the housing to prevent arching.

Hi, I have a Mercedes B250. The key fob stopped working and wouldn’t unlock the doors. I use the manual key inside the key fob to unlock the door and was luckily able to start the car with the key fob itself. After I got home I tried the key fob again to lock the door and unlock it and it worked. I’m afraid that this is going to happen again. I don’t know what the issue is. The car started so I can’t be the fuse. Does anybody have a similar experience and have a solution to share? Would very much appreciate it. I hate car problems!

[@PeterZafra]

Have you tried changing the batteries? If not, try that first and then if it still does it, then your key fob might need to be reprogrammed

[@James-akaRhino]

Yeah eventually I had to get a new key fob and they reprogrammed it. somehow those things wear out over time. cost me $180 4 years ago.

[@CapelloFamous]

how did you get into the car? my car is locked and I am looking for the best way to unlock the car so I can change the fuse.

[@hr.linnas5329]

Take the emergency key from your main key, and unlock the driver door.

[@capitalrealestategroup6426]

@@hr.linnas5329 same issue here but the key won’t unlock the drivers door? 🙃

Guys please help I have a Mercedes Benz c200 w203 2004 the key does not turn in the ignition at all. I can only lock the car use the remote (key) but can't lock it. I don't have the spare key to test. I checked fuses they all are fine. Any advise in the area would help a lot. Thanks

[@PeterZafra]

Try cleaning the key fob out. This could help. Sometimes lint could block the infrared sensor and prevent communication with the computer. Cheers. kzbin.info/www/bejne/ZouQiqKFZcSIqac

Thanks for the information I am having the same problem 👍👍

[@KH_KTV]

I had same problem, I still can’t fixed, buttery is good and the key also good but car no power at all

[@PeterZafra]

Double check fuses. Most of the time it's the problem. Check battery on keyfob and make sure keyfob is clean with no lint inside covering sensor

[@elizabeth5288]

Do u know how could I fix it

[@PeterZafra]

I personally haven't worked on a c230 but it definitely won't hurt to try this procedure.

[@wilkinsbrito5168]

passin' joe errrrrrrrrrr lol I saw what you did there.

[@popevids1942]

Everyone video ppl skip over how they opened their car.

[@PeterZafra]

Mine didn't have the issue of not being able to open the car. Mine was not starting due to the blockage. Cheers

[@jasonhitch660]

It’s a Mercedes. Never that easy! It’s a piece of shit! My wagon is garbage. Close on junk yard if it doesn’t run by tomorrow

[@PeterZafra]

I agree but i still love my euro trash

Bla, Bla,Bla this video should have been 60 seconds.

[@sanchoclos1963]

I have a 2006 s350 the key does not lock or unlock the doors and trunk does not turn the switch, the fuses are fine, what else can I check

[@PeterZafra]

Make sure the battery is fresh in the keyfob. If it's good, then your keys might need to get re programmed

[@James-akaRhino]

My fob was acting up. I changed out the batteries. 2005 S500. Took it to the shop. They had to get new fob and reprogram. $180. 4 years ago.
