Driver's door keyless not working

[4eva]

Hi guys, this morning I noticed the driver's door handle on my W211 E230 seems to be faulty.

 

I am unable to unlock the doors using keyless entry or lock it with the button on the door handle. However, locking and unlocking seems to be working fine on the passengers door.

 

Currently I have to unlock it using the passenger's door first before I can open my door and lock the car using the passenger's door lock button. 

 

Anyone can recommend me a place to get it fix or any solutions will be appreciated, thanks!

First thing I would suspect is fuse

I searched the net and it seems like a common issue for the W211 keyless go. Looks like the whole handle have to be replaced

 

Any affordable workshop recommendations that do the above repair hopefully?

Hey 4eva,

 

In my 4 years of ownership of the W211, I changed the door handle 4 times for the same problem.

 

2x front driver, 1x passenger, 1x rear right

 

The price varied between $190-230 per handle (with or without spray paint, depends on how you haggle).

Buy from Golden Link then get it sprayed paint at somewhere you trust is the cheapest way to go.

It only takes like 30 seconds to get it replaced if you have that long screw driver thingy.

Thanks bbwannabe for the detailed information! A bit reluctant to change but guess I'll take a look at Golden Link

goldenlink is selling at $270 per piece if i not wrong... have to spray by yourself... 

 

mine all is not working already... only using the key to lock and unlock.

This door handle you can order from Tye Soon Ltd with colour code (no need to spray paint) for $200 plus too.  Though I remember they sell the non painted handle for less .

Common prob, mine only driver and left rear passenger fully functional. front passenger can lock only. right rear sometime can lock only but most of the time dead. My guess is that water seepage into the handle causing oxidation/corrosion to the circuit board.

From the above www.keylessfix.eu webpage, Cost is €150. But dunno take how long? 

Anyway, I found a DIY solution from mbworld.  Boy,  this guy is a genius and gung-ho/daring enough to try and repair the handle. 

Me alone may have problem taking out the handle itself.  Lol

Probably it's the gonna be same way of repair as www.keylessfix.eu.

Let's see if I could attempt doing it. Currently 3 doors keyless lock/unlock are malfunctioned.

Is not gung-ho it's because labor is very expensive and parts is very cheap.some of  the owners in the western countries DIY to save cost.

 

For example changing motor mount and gearbox mount rack me up to 1.1k USD. 

but his write up is very good can try to do.
