    I appreciate you bro. My daughter dropped my keys to both cars clk430 and my bmw in a bowl of water. The bmw key worked as soon as I dried it off but the Mercedes key wouldn't open the door or strat on e I got it open. I replaced the batteries and that let me unlock it. It still wouldn't start so I did what you did in the video I took the key apart and cleaned all the water marks off and placed the folded paper in the and put it back. I tried to start it again and it worked. 3 hours later I was finally able to move my car. Thanks bro that video saved me time and money. You the man👌🏾

    Thanks for the video! I have the newer style key, with the chrome sides. Going off your solution, I opened up the key by sliding off the two chrome pieces and cutting through the glue joining the plastic, and put a rolled-up piece of paper above the IR sensor (little rectangle right above the panic button) to keep it pushed down. Seems to have happened from the key being dropped one too many times. 20 minutes saved me 400 bucks!

    Thanks man and I have a lucky find for you. I changed the battery in the key fob and still the key would not turn. Also the trunk release inside the car would not open the trunk so I thought the car battery was dead. New keyfob battery but the door lock buttons would not unlock or lock the doors. I crawled into the trunk by pulling down the seats in the car. I thought maybe there's a latch in the trunk I can pull, but I hit the trunk button on the keyfob while I was in the trunk and everything works now. My mechanic said there is a sensor in the trunk and by getting closer to this sensor the keyfob with a new battery was able to reset. Everything works as normal with no error codes. Time for a quick "Italian Tuneup" up to Malibu on the PCH. Hope this helps!!!!!!!!

My unlock button dint work after the first try. I took everything apart and observed that while removing the battery, i had expanded the metal brace that held them together. I adjusted them and voila! Everything worked perfectly.

      As an electrical engineer, when I looked at the key fob, I knew it utilized an infrared sensor.
      When I had the non-start issue, I immediately thought of “the average tv remote, not being directly pointed at the tv, and thus not being able to change the channel”.
      Thats how I realized, the key fob was not aligned due to the old worn out plastic housing.

      @@EdBoyle-w1z I have not experienced your 3rd symptom described…
      For me the issue was that the Infrared LED’s in the key and the vehicle tumbler would not align. And thus would not allow the key to be rotated at all in the ignition.
      I am not sure about your issue.
      If the key can be turned but the engine does not “turn-over”, you may want to look into investigating if your starter is on its way out.
      The “brushes” inside of the starter may be worn out…there are a few places that sell the brushes rebuild kit for around $10 USD, but you must have the starter removed from the engine before someone can install new “brushes” in the starter.
      you may as well just buy a new starter from www.rockauto.com and have the repair guy install it it.
      As the labor hours for rebuilding a starter with new brushes can cost even more than just buying a new starter (parts cost only).

      But the goal with this fix is to get the infrared beam led and receiver to line up between the key and the tumbler in the car.
      Keep trying with the paper method, and also try to gently/slowly wiggle the key to the side while trying to turn the key/car on.

    I don’t know how often this needs to be said. The batteries in the key fob play NO part in allowing the key to be turned or in starting the car. The fob is instead powered after insertion by an induction coil surrounding the key. The fob batteries are used only for locking and unlocking the car remotely. This is why you can use the emergency metal key to unlock the car and the key fob to then start the car even if there are no batteries in the fob.
    I expect the problem in this case is a dry joint in the soldering and stressing the board with the paper wedge makes the connection. I don’t think it has anything to do with the optical alignment of the IR transmitter and receiver.

    • @frugalfabrication
      @frugalfabrication  5 лет назад +1

      Thank you for explaining the batteries in the key have nothing to do with starting the car.
      Also, you may be right in the fact that there was a dry solder joint as well. In any case, the beauty of this is that you can fix your mercedes key fob with a piece of paper.
      This is An issue where if you went to a mercedes dealer to fix, you would be shelling out a substantial amount if money (~$500 to $1,000+ USD) to resolve.

      I really don’t understand your motivation for posting this nonsense video. It has no sound engineering basis and it’s ridiculous to pretend that stuffing a piece of paper into the key will fix all problems. It just happens to in this case. Far better to send the key off to someone who has some real talent and experience who can look closely at the soldered connections and make the necessary repairs. Take a look at the videos by NorthridgeFix. There’s a guy who understands what he’s doing and brings the tools and experience to the job to complete it successfully. .

      Mark Norton Ok, not everyone at any exact given point and time has the immediate ability to just send off keys to be copied, and go without their vehicle for however long it takes to
      1) have an electrical specialist get to their key in the order it was received.
      2) or leave their car wherever it may be stranded (as they have already known their key case is faulty, but have been dealing with it for quite some as they do not posses the $500 to just give to the mercedes stealership who rips them off making an ~$15 (near true circuitry value) key copy.
      3) need their vehicle up and running immediately as they may have work the next day or in the next few hours, and can’t afford to pay for and maintain the cost of a rental car for up to 2 weeks in order to send off the keys (as you so geniusly recommend) to a specialist who will need time to diagnose, and then send you the invoice for repair and await your approval to begin.
      I could go on listing more reasons, but I won’t.
      If you don’t like the vid, you can easily keep it moving to another youtube page.

      I Always do it this way with cars, because the negative battery terminal is grounded into the cars Chassis/body.
      Imagine if the negative terminal is still connected, and you are removing the positive terminal first, and as you are un-tightening the positive battery nut and you mistakenly make contact with the chassis...a nice big arc/spark will occur.
      Keep in mind this can damage sensitive sensors as well. So to avoid this, disconnect the negative terminal first always.

    After changing the batteries I was still having problems starting the car. I opened it back up and bent the metal that goes around the batteries inward so that it makes a better connection to the batteries. It started up right away with no problem after that but then it had some problems again. I discovered that pinching the fob so that the batteries make a connection while turning the key is the answer and it starts right away.

      If the key is literally broken (as in electrical circuit componnent...capacitor, resistor, etc) broke off, you may want to google or read through the comments (someone posted about a year ago) of an actual electrical circuit tech repair shop for the key. Take all plthe pieces that fell off to the tech and have him solder back on.
      If key is physically broken into several pieces, you are better off purchasing another key and having it programmed to your car. This is possible, but the specialist doing it will need the mercedes CGDI key programmer equipment.
      If you are not tech savy, find a specialist or someone to do it for you. They may charge youa around $350 USD (at best) to $400...It won’t be cheap, but usually will be cheaper than the dealership (dealership may want you to buy a whole new key and electrical lock tumbler set and install in your steering wheel....very expensive at mercedes.
