I have a 1996 C280, the problem is with the keyless entry. You have to be within 3 feet or less for it to work and sometimes it does not work at all. I have a S500 which works from 25 feet and a gs300 which works from 30 ft. I have replaced the bats and no difference. Is there anything else I can try? (daughters car)

That is why they went away from the Ir signal and went to the Rf signal.

Sorry,

Is there any solution that you have found ?

Didn't the car come with two key/transmitters? Do you get the same result from the other one if you have it? My car also has sensors on the windshield side of the rear-view mirror and on the trunk lid. Do you get the same results there? If the poorest results are the driver's door, maybe that's a bad sensor.

I would explain it to you daughter that this is the way the "feature" works. The system was designed to work only on line-of-sight so that no one could intercept your code (unless you pointed it directly at them). With fresh batteries, mine works from about ten feet away. Ask her point the fob directly at the door handle from about ten feet away and give that a try.

Hi,
My 1996 C280 works the same. Have to be within 2-3' for the the keyless entry to work.
By the way.. Does anyone know how I can turn off the green/red lights on the rear mirror? I don't know what I did but now they both blink when I press the button to open or close the doors.

Thank you,
Melinda

Check the remote battery then try resetting the remote. Instructions are in the owners manual.

Hello,
I have disconnected the battery, followed instructions"as per manual" and still I have this challenge of dual blinking lights on the rear view mirror. Any suggestions?

Thank You,
Melinda

When mine blinks red & green at the same time I know it's time to replace the battery in the remote.
