Keyless Go...."Engine Start" button isn't working....any ideas?
I just came back from a 600 miles trip and my "engine start" button is no longer in working condition. I have keyless go. I can open and lock the door fine without pressing the lock/unlock button on my key. However, I cant start the car by pushing the "engine start" button. Does anyone have any idea why my "engine start" button is not working? BTW, the car starts fine if I do it in the traditional way.
Thank you!!!
Thank you!!!

My foot is set on the brake. I check the manual and it says that the battery might be low. They recommended that after a few tries and the car doesn't start still then I need to take it in to the "stealership".
I do not get the message "key is not recognized".
Anyone else have any idea to why it is not working? Thanks a bunch!!!

If you're not getting that message, I think maybe a switch related to the engine start button may be malfunctioning? I wish I knew how the circuit for the keyless go worked, then it would be pretty simple to figure out where the fault lies.

I occasionally get in the car and my keyless go doesn't work right off the bat, but I get a error on the display saying key not recognized. I think the battery in my fob is dying, which could also explain why sometimes the keyless go entry to the car doesn't always work on the first try.

Take a small flathead screwdriver and pry the button off the shifter. Comes off easily. Then take a couple inches of electrical wire and connect the contacts on the shifter. If it starts, your knob is acting up. If it doesnt and you get no error messages on the dash you probably have a broken wire in the shifter module. theres a DIY on it here

Engine start button doesn’t work
I have an E class 350 2009 AMG Sports Package. I wonder if there is a way to program/activate the start engine feature? The button is located on my stick shift. I have keyless go in my car but I’m only able to open the rear right door with the key in my pocket the other doors won’t operate the same. Does anyone know anything about this issue?

Your door handle issue is a common one and you'll need to replace the door handles. I'd pull the shifter knob off and check for any broken wires. There's a retaining ring thing that needs to be turned 90° IIRC before the knob will come off. If that's not it then it could be a bad button. If the car has the stop/start button on the shifter it's already programmed for it (providing someone didn't just stick that shift knob on it).
