Not only entertaining and informative, this just might be one of the most _important_ MBZ videos I've ever seen!

You fixed problems dealers can't and you present this issue in such an entertaining way & more importantly, educating the general public 👍. This proves again dealership can't solve anything even with their vast resources & access to internal MB records, sad. Glad people like you still exist, thank you SIR !🙏

Since buying a Mercedes Benz, this has become my favourite channel on youtube.

You are THE MAN. Thank you so very much for taking the time to share your wealth of knowledge. If only I had found your tutorials sooner, I would have cried ten thousand less frustrated tears.

Your videos have help me a lot I have the E350, S600 and my wife have the C300 we love the Mercedes Benz. My wife and I would always put our keys in the same cabinet drawer in the kitchen and when we walk into the garage the cars will wake up beep and lights flash even when the keys are in the drawer. The way I fix the issue was separating all the smart keys further away from the garage in different rooms now our cars rest easy

I love the way this video is set up, and the handshake thing, really helps you learn and understand way better. Ty so much.

So educational- thanks so much @MBZ Master. I am dealing with a dead battery right now & was absolutely puzzled. Great tips to get me on the right track once I charge and get my battery going again!

Thanks for your speedy response to my query about c250 auxiliary. Keep up the good work. 👍

Excellent, as always.

My 2018 C43 showed warning message “Stop Vehicle, Leave Engine Running” when I start it this morning after two weeks not driving. Will follow your instructions. Very helpful 👍 Thank you.

😂😂😂🔥🔥 I LOVE YOUR VIDEOS AND EXPLANATION. YOU’RE THE BEST. please don’t ever stop making videos.

Thank you so much for your tips on different things that we may not have known about our mercs! I now know a lot more about the different things that you have shown on your precious and valuable videos. Thank you so so much my friend 👌

your videos are so helpful and with a nice sense of humor. thank you!

This just one smart person! This is one you take a problem seriously and do not stop until you fix it. It also shows that hooking up testing devices without deep knowledge of the function does not fix car.

I love watching your videos. Great info. I wish I had bought a car from you.

Love this style of presentation!

Very educative. You are doing a great job, enlightening Mercedes Benz fans

This was so useful, I would never have guessed this was the problem! I just purchased a Merc A250e sedan and it has keyless go. Will definitely follow your guidelines.

You are very clever. Thank you for this information.

Sir I salute you with your wealth of knowledge on Mercedes it has helped me so much setting up my recently purchased 2018 C200 2 door coupe, love you humour too, keep up the good work!

Just got my first MBZ and just want to say THANK YOU!. you have helped me sooo much understanding my car better than the manual.

This is outstanding information. Thank you for sharing!

Awesome tips! Explains so much!

Brilliant video! You can’t believe how much I have spent on new batteries for a stored vehicle that I stopped driving 7 years ago, nickel battery retainer and all! This is surely the cause of the dead batteries..

Great info. I have a 2011 E 350 coupe. It is a totally under rated car. I bought it second hand and never got the dealer run down. This channel is very helpful. Thanks!

Thanks for the revealing information!! My first car equipped with Keyless is my actual GLK 350, in fact I came to this video because my batery died "for no reason" after 3 days of no use and this video was an eye oppener for me because I used to store my key pretty close; problem is being a 2013 GLK I can´t disable the Keyless Go by double click and I can't find any other way to dosable it.

THANK YOU!.

Excellent Information

Good to know! Thanks!

Thank you so much man I have a 2021 car and last weekend I took it out side the garage to wash and wax it but I forgot the stupid smartkey fob inside the car after 2 and a half hours detailing the car when I went to start it the battery already drained it's so frustrating especially when you take your car to be fixed and they all tell you that their is nothing wrong with your cars battery I needed a jump start that day.

Glad that I looked at this video before calling the dealership. I put my C 250 up for the winter. I went to start it and it's dead. I know what to do now. Thanks.

This is a very good video.

Very educational

Thank you! I just got a cert preowned 2022 GLB today, & was looking at various youtube channels for info. And your videos are so informative. This is my first keyless go car, & I always used leave my keys in my car when I got home. You saved me from dealing with what your friend went through. Question, how far away do my key fobs have to be from the car? We keep our spare fobs in the laundry room which is on the other side of the garage. However, our cars are about 8 ft, & 15 ft away from the cars. Thanks again!😊

So I've been having the EXACT same issue with my 2016 CLS 400, decided to come on KZread to see if I can find an explanation, stumbled across this video and EVERYTHING that was mentioned as the cause of my battery stalling after a few days of not driving was exactly what I was doing. Over night, I hang my key up by my back door and surprise, surprise my car is parked right outside my back door. It makes sense now. I'm definitely going to disable the keyless entry feature and keep my key as far as away from my back door as well. Hopefully this works!

Just remember, if your battery went down multiple times already, it may never recover and at this point may need to be replaced anyway. Try to keep your key away from a car for 2-3 days of not driving and see if it holds charge. If not, maybe it's too late to save it. But in the future, make sure to keep your SmartKey away from your car, so it won't happen again.

Thank you for the reminder to charge my battery

Genius!!!!!❤❤❤🎉

I always leave my key hanging in the house door lock at night ( inside obviously), while the car is parked outside, maybe 5 metres distance. The car battery never died, I never really gave it more than a day off, but I had to replace the key battery with a 12 month period. Might be unconnected but I going to move the keys at nite to the back of the house and use the disable function too. Great tip. Thanks

Love you... your FABULOUS !

Good information. I just bought my wife a newer car and the spare (aftermarket) key fob battery keeps dying within 4-5 days. Her OEM remote doesn't have this issue. I keep the aftermarket fob in the garage which is nearer to the car (although the car is parked outside). I'll move it back further in the house and see if the fob battery lasts longer.

Amazing video, my car battery was dying as well, also the battery in the fob was dying. This is my first keyless smart car Mazda 6,2017 and I was just leaving the keys in the car because I have a garage attached to the house. My battery is only a year old but my old battery was having this problem too, so like an idiot I bought a new car battery last year when I probably didn't need it. This keyless fob issue has given me so much problems, I was even thinking of trading the car in for a new one soon. 😆

Thanks for your explanation, I has mercedes 450 gls 2017. I learned a lot from your videos specially I can close my car windows with out starting my car. I impressed my children that I can do some voice magic ""Close the windows"".but they don't know i hold the key button. Thanks love from Connecticut USA 🇺🇸.

I am facing same problem with my Merc Benz 300 in Hong Kong and have struggled over last 4 months . I went to mechanic few times and asked him if I need to replace my battery but he always checked and said battery is healthy and good . And other problem was my smart key's battery running out quickly .I carry a jump start and have to use it twice each day .But now I know and will follow your advise .Thanks a ton to you 🙏

If you have to use the jumper twice a day, most likely the battery is already compromised to the point of no return, and needs to be replaced.

I don't think you can turn it off because it designed to light up the interior while the rear door is raised, but those lights will turn off automatically after a while - to preserve the battery. So, just put some black masking tape over those lights until they switch off automatically.

Thanks for video.good information.by the way i love Mercedes-Benz.🇸🇮🇸🇮🇸🇮👍👍👍😎😎😎😉😉😉

Never thought of it. 🙏

Great info. I am completely in love with keyless go. Never had a problem although sometimes it locks, unlocks, locks unlocks, when I am near with key in my pocket. Not felicitous when I'm handwashing the car. So annoying. I wouldn't give it up though. Completely spoiled with this great convenience. No more searching through my purse for several minutes then dumping out all on pavement locating my key while lurkers decide to shoot me or worse....!

When washing the car, just hit the lock button twice and you won't have that problem.

Double click the lock button, priceless, thank you.

My first car with keyless GO was a W220 S500

Fascinating...and absolutely logical. I never experienced this but should have realized it. We don't keep our keys close to the car but sometimes don't drive a car for days...weeks...sometimes even months (usually winter months). That's when a CTEK battery tender comes in handy. Anyways, a quick question...what if you don't lock the car? My cars are always garaged. Would leaving them locked or unlocked be better when it comes to battery drain? Or would it not make a difference? My first smart key (KEYLESS-GO) was with a W220 S-500 at which time, iirc, it was an option. Since then, it has gone more mainstream and KEYLESS-GO has become, at least with my experience with S-Classes, pretty much standard. That includes my W221s and W222 as well as the W223s and EQS that I test drove last week.

Your car is always looking for a key, whether it's locked, unlocked, or even when you start and drive it, your car always communicates with your key. The only way to stop the communication is to double-click on the Smartkey's LOCK button, as I showed in the video. That disables the Keyless Go, until you use it again.

Can you make a video on how to turn off the SOS service light on a 2017 GLC300

A 2006 S350 was my first car with keyless go.

You are right that in MB it disable the keyless go on the remote control to stop talking with the car, but the car is still searching for the key when it is near and on. You can check it if you disable the keyless go with one key, but if you bring from far the second one that is on before you get near the car, when you get close to the car the will open without pressing anything. So you are disabling the remote, but not the car.So if you will park in a big parking lot, the car would still search for an active key near by. It is true that if the only key around is disabled it will not drain the battery, since no other key is around.

Correct, but the drainage of looking for a key is extremely minimal, comparing to the battery drainage of when the connection with the key is established.

If you double-click the lock button, because it will disable the KeylessGo, so your car will stop looking for a key. Note, it doesn't drain a lot of battery, but it will accumulate the drainage toll over time, or if you don't drive your car every day.

Brilliant. My app tells me continually that my battery is down on my amg after a few days. I also put my keys into a faraday pouch!

Try to disable the Keyless Go feature completely, as I showed, and see if the problem persists. If it does, - then the problem is not caused by your SmartKey.

Thanks for the good advice! One question: how to turn keyless go back on (MB GLB)?

That is the reason why my battery keeps draining and draining again and again thank you very very much for this info.I had the same situation cuz I keep the smart key in my car.I hope this works,if this works you would be like an angel to me.

Now I know why I have had to replace my smart key battery so often for my 2019 Mercedes GLC300. I never would have figured this out...

Easiest think to do is put your key fob in aluminum foil…..It acts as a quick and dirty faraday cage and works very well….you just have to remember to do it…. 😊

@MBZMaster

Жыл бұрын

It's not easier than to press the LOCK button twice (if you have Mercedes), but the foil will also work.

Omg this happened to me. Dealership thought I was crazy. Especially with the pandemic. This never used to happen before. I think we replaced 4 batteries in a year

Very educational thank you so much. Question: if I keep the spare smart key near the car but wrap it in aluminum foil, does it prevent the key to communicate with the car battery?

@MBZMaster

2 жыл бұрын

Yes, but that would be too much of a hassle. Much easier is to hit lock button on the SmartKey twice (if you have MB) - that would disable the Keyless Go until you use the key again. Or just keep it 10 -15 ft. away from your car.

I just replaced my 11 year old OEM Varta with a Silver Dynamic Varta. The star-stop works again. The glow plugs heat faster. Hopefully it sees 11 years too.

Since 2019 Mercedes has equipped the Keyless Go controller with a movement sensor. When you lay your controller on a desk, a shelf or into a drawer it will fall asleep. No more checking, no more sending, no more hand-shake. This was done mainly to prevent theft through copying the controller-signal with special devices outside the house near your car while you sleep at home with your keys in the kitchen-drawer. But when he (was it Steve?) opens the drawer frequently to pick up some other items or to lay them back the key will wake up each time. Drawer? Bad idea! Put it on your desktop in your home-office or into a box. I have my controller on a shelf with significant distance to my house-door and even further distance to my car.

@MBZMaster

That's true. Latest MB Smart Keys fall asleep if not used, but the problem is they are very sensitive to even slight movements, like wind, drawer movements, floor shaking etc... so I still recommend to keep them at the distance from the car.
