Hi, just bought the 2005 CLK 320, it's equipped with keyless-go and I should be able to unlock the door just by pulling the outside door handle.

That doesn't work that way for me, is there any programming that I should do? Any suggestions will be appreciated. I read the manual, no luck.

Door handle that senses your hand is bad. Need to replace the door handle assuming the other door handles on the car work as expected. There is no coding specifically for what you asked for.

 

[m.e.g.]

No programming is required. Does the passenger door open by just pulling on it?

The ignition starts fine with the key in your pocket?

The engine starts fine, the other door will not open as well. Would both handles be bad?

It's possible that both are bad. On the W220 with keylessGO I've had to changed all of mine because of this problem I've the last 5 years. I'm relieved mine are bright silver as that's the only ones they sell pre painted.

 

[m.e.g.]

Since the ignition starts with the key in your pocket and neither doors open, seems the connection from keyless-go system to the door lock system is not working. You need the connection and wiring diagrams for the keyless-go system to troubleshoot the problem.

Noticed you stated you just bought your car. Can you take it back to the dealer and have them repair the keyless-go system?

yes just replaced 2001 e320 with this one but about going back to the dealer...
I have stopped buying from dealers many years ago and I'm not going back.

I'll do some more research about this problem, thanks though.

Do the lock buttons on the outside door handles work? If so, then the problem is with the sensor for your hand on the inside of the handle. If the lock buttons don't work, you may have problems with the antennas in the doors.

The lock buttons on both doors don't work, however I can open the trunk and the lock button on the trunk lid works too. Is the door antenna replacement DIY?

 

[rudeney]

Yes, if you can remove the interior door panel, you can replace the antenna. It is located inside the door, adhered to the sheet metal, between the stereo speakers. However, since both doors have the same problem, I find that a bit odd. There are also KeylessGo control modules located just under the "sail panel" speakers. I might start by checking the wiring harness to make sure everything is in place. If you need the antenna the part number is A2098200475. Note that with SDS, a tech can actually determine the real problem. Otherwise, you are just "throwing parts at the problem".

 

[m.e.g.]

SDS diagnostic is probably the most cost effective approach.

If, the Keyless-Go key was not correctly programed could cause this problem. As stated, both doors having the same problem at the same time is possible but not likely, really points to a problem common to both doors (something associated with central control module).

Seems to be Keyless-Go system is not communicating with door lock system.

Can the doors lock/unlock with the button on the key? This would seem to point to the antenna not receiving the signal or the key not sending the signal to the door lock system.

Keyless-Go key works fine and the trunk lid works but the doors would not unlock when approaching the car.

Rodney, I've got a Keyless Go problem too; posted here a month or so ago. Will be getting a new battery and diagnostics tomorrow (Tues. 4/07). What is SDS and where are the various modules? They sound a lot cheaper than an EIS. Thanks, Donn

Antenna's dont really go bad. Your keylessGo door handles need to be replaced if that's the only problem that you cant unlock either door with the keylessGO key in your pocket.

I responded to you problem on thread #3 on your link above.

SDS = Star Diagnosis, i.e. the official workshop diagnostic tool. It can test and actuate the various electronic modules in the car, including those that operate KeylessGo.
