Question about Smart Cars & Trucks

1 Answer

Mercedes e320 2002 smart key stopped working all of a sudden. No red light on the keys when i press the button except when i press the unlock/lock button together for 5-10 seconds. Batteries are new. When i open the car manually, and put the car keys into the ignition, key does not turn and it just says "remove keys". Strangely the car headlight and interior lights work though so the batteries don't seem to be completely dead at least. Whats going on?

  • Reset your Mercedes-Benz key by placing the key in the ignition of your vehicle while the vehicle is turned off. Do not turn on the vehicle. Press a finger on the "lock" button of your key fob while the key is in the Mercedes' ignition.

  • Pull the key out of the ignition while continuing to hold the "lock" button down. Continue to hold the "lock" button for the duration of the key resetting process

  • Use another finger to push down on the "unlock" button five consecutive times. Keep holding down the "lock" button.

  • Release the "lock" button. This is the end of the resetting process for your Mercedes-Benz. Use your key fob to ensure it is properly working

    How can i reprogram a mercedes slk r170 key fob to my car


    If it is a new key or replacement only the dealer can do it. if it is one of the original keys that stopped working then place it in the ignition and press the lock button 5 times in about 5 seconds, then press and hold down the unlock button. Withdraw the key and try it.

    I have a 1999 E320 Mercedes and one of my key fobs stopped working so I replaced the batteries in it and when I prees the button now the red lite indicator comes on but nothing happens? My spare one is...


    IT WORKED!!!! The manual on my 99 ML430 to "Resynching Remote Key" was just written weird.

    It says "Turn the key in the ignition to 2nd position then back to 0. Press and hold the lock key for 15 seconds... now press the unlock key 5 times"... which I held down the lock button for 15 seconds, released it, then pressed the unlock key 5 times. NOTHING!

    The newer manuals say press and hold the lock key and press the unlock key 5 times (with the lock key still held down).

    So... it worked. Hope this helps!

    Mercedes 1999 c200 key fob


    Hello Haq!
    Could it be the key just needs re-coding? maybe you are worrying to much as £177 would be about right as that would need coding etc., Try phoning your local Merc dealer or take the key and V5 to them for coding (Hopefully)
    Good Luck!
