It is one thing to get locked out of your car by forgetting your keys, but it is another thing all together to get locked out by not replacing a door handle that is going bad until it break and leaves you stranded. Don't get stranded out of your C320 by replacing that failing handle before it breaks.

If you are going to be removing or replacing the backing plate on the door handle you will need to remove the door panel first. Please see our article on removing your front door panel. If you are just removing the handle you do not need to remove the door panel.

The front door handles on the Mercedes C320 are held in place by a single T20 Torx screw that screws into the part that holds the lock and the infrared sensor.

To remove the lock section you first pull back the weather strip on the inside of the door level with the handle revealing the access holes. Insert a T20 Torx driver and unscrew the screw going into the lock. You will have to do this by feel as you can not see inside the door. Make sure you use a proper T20 driver and not a bit on the end of a socket. If you use a bit and it falls off inside the door you will be removing the door panel to retrieve it.

With the screw loosened pull the lock out from the handle. Remove the infrared sensor plug. Take a moment to notice the "fin" on the end of the lock and look inside the door to see how it lines up with the lock/latch mechanism inside.

Pull the handle out and then towards the rear of the car to remove. When you are reinstalling the handle you will have to make sure the "L" shaped end goes behind the lever in the lock/latch assembly.

To remove the backing plate, remove the two gaskets and then the single T20 Torx on the front part of the handle.

You can now slip the backing plate down and out through the access panel on the inside of the door.

Installation is the reverse of removal.

Ray Comments: Hi once. You disconnect the cables for lock , do you need to program it or not

  Followup from the Pelican Staff: No. - Nick at Pelican Parts  
Steve Comments: Nick, thanks for following up. Turns out I didn't have the plastic piece where the lock engages and it presses the door switch so the car knows the car door is closed. Without the plastic piece, the car thinks the door is still open even when it is closed. My error and lesson learned.

Steve Comments: I replaced the driver side door on a 2002 Mercedes c320. The driver side door does not lock with the key remote, but does unlock if I press the lock down. The door handle works fine opening door from out side and opening door from the inside. All other doors lock and unlock no problem with key remote. I made sure to use the same infrared lock from the old door. Any help is appreciated.

  Followup from the Pelican Staff: You may have an issue with the new lock. You should check to see if the module is seeing the signal, confirm it on a scan tool with the working locks, for for similar signal from the faulty lock. If not present, it may be the new part. - Nick at Pelican Parts  
Glen hoz Comments: 2012 c250 right rear door, Opens from inside but not outside handle? I am trying to see when you pull handle how it opens door from outer pull handle. Not sure if actuator or handle itself is broken or maybe glass in actuator as once the door glass was broken. your site is awesome thank you!

me Comments: how do you reinsert the brace on the rear doors? I pulled one by force, but it doesn't go in. Any clues?

  Followup from the Pelican Staff: What vehicle are you working on? The support bar in the door? I believe they bolt in. If not, your may slide into a channel and lock into place with clips. - Nick at Pelican Parts  
Chris Comments: I owe you the coldest beer of your choice. This was paramount for me the other night on the 2002 C240. Saved me, thanks!
