How do you reprogram the key remote of 01' ml55
1. put key into ignition and turn to position 2
2. remove key and press+hold the lock button
3. while holding down the lock button press the unlock button 5 times
4. release all buttons
5. press either the lock or unlock button to finalize the programmning
Thanks for the info.
I did exactly what you instructed and it locked the doors but it wont work after that. None of the buttons operate. Is there another step after programming?
Thanks
The first time I did it I was not holding the lock button while pressiung the unlock button five times.
If you are doing the procedure correctly and it does not work right, then you might have to take a trip to the dare I say it.......dealership gasp!
Sucks, but it might need to go there so they can program through the Star Diag. ... If you are good friends with your advisor or bring him some doughnuts or something they might do it for free.. I have heard some dealerships actually charge for it...
Sorry I could not have been more help...

I did exactly as listed in the instructions....and now it works perfectly.
Thanks everyone for sharing your info.
