Hello

yea, im another one, my keyless aint working. I tryed to search lot of threads here, even for 211, but i didnt found any good answer for my kind of problem with this crap. I have 2009 CLS550. Both my front doors doesnt lock and unlock. Drivers side, and passenger side front doors. Locking buttons and unlocking buttons dont work. Car is at 80 000miles atm. Door handles are in perfect condition. I dont think this is problem with door handles. I think it might be module. Or maybe wires? Does any one had this kind of problem with keyless?
Also one thing, previous owner split some suggary lemonade onto driver door panel. That caused very sticky window opening buttons which im about to change (just got new button panel). So im curious if i find something on that keyless module. But even if i do, and that module will be damaged, i think every door have its own module or not? I did find in some service manual that each of rear doors have its own module, same as trunk and start button. I didnt find anything about front doors tho. But im pretty sure there will be separate module for each front door too.

If anyone had similar problem with more then one door and both lock/unlock not working, pls let me know. I would love to have some shortcut with this... thanks!

For precaution check f22 & f33 @ interior fuse panel (driver side dash), pull front door linings to check modules, and revisit door handles. All fine, need to have someone pull fault codes using MB diagnostics.
