A few months ago p_web posted a key for his coupe with the trunk release button..is this available for the coupes? And regarding the 217 and 221 issue..how can i get this 221 keys to increase the distance for the remote....is theis free ...or better yet i want the trunk release..is this free?

thanks

 

follow thses simple steps

1 take key out of pocket

2 put key in microwave

3 enter 30 second

4 hit start

5 be careful ti watch key so that it doesnt melt. When it starts to melt or smoke immediatly take out.

6 take remote to dealership and say it mysteriously stopped working

use at your own risk

 

thanks for the advise...i tried that it didnt work so i just crashed it with the hammer i will see the dealer tomorrow and have them explain to me what happened. But seriuously what is going on about this key issues?

 

Did you do that on your own??

 

no

 

hahaha too funny

 

Remember there is only seven infrared keys for a Mercedes an no more. Try not to go through them all. If you do the dealer charges $$$$ to reprogram a Mercedes to seven new keys.

 

I believe it is not as easy as reprogramming the car. I think the ignition switch must be replaced.

 

Does your remote work at all from a long distance, say 20 feet?

Do BOTH keys work from 20 feet?

Do both keys work fine (for ALL functions, trunk etc) when right next to the door and pointed directly at the sensor?

If you answered
No
No
Yes

then the RF section of your CAR is probably out.

Your friendly MB dealer will have to dismantle the headliner and replace a RF amplifier in the area near the rear window.


BTW I don't think the 221 key has any better range, I think the 217 key sometimes simply doesn't work.

 

They do not replace the ignition switch, they replace the computer controlling the infrared key system. I think it is terrible that the customer cannot control thier own key system without having the dealership dictate the key control. On the other hand, I truly enjoy a Mercedes and I can overlook that small problem. Other auto manuf. have transponders that can be programed by a locksmith with the right equipment.

 

does anybody owns a coupe that has a trunk release button on their keys? cause i called up two dealership and they say that coupes and wagons only gets the lock and unlock...i rerally want to know cause that will be a good feature to have

 

i think that might be true. the C320 Wagon loaner i got from the dealer only has lock and unlock feature on the key.

 

I test drove a 2002 coupe that had a 3 button key and a 2003 that had a 2 button key. I don't know why and i didn't think it was a big enough deal to ask. I don't see why they would need a seperate trunk release button as long as it opens...

 

Where did you test drive it?

 

In Pennsylvania...

 

On the 2002 C230K, that were sold brand new, came with only two buttons, the replacement transmitter comes with three buttons. The third button does unlock the trunk, the trunk is set up for the third button release from the factory

 

Its interesting you say that because I brought my car in for the 217 bad key and a problem with am radio reception at the same time. They gave me 2 new 221 keys and replaced the amp in the headliner over the rear hatch. I wonder if they would have just replced the amp in the rear window if it would have obviated the need for key replacement?

(Not that I'm complaining, because I have the trunk release and more am and fm stations than I knew existed.)

 

RF seemed to be "out" on keys (actually the car), worked fine for IR line-of-sight.

1) I had keys replaced to newest version, no joy.
2) 1 month later, RF amp replaced in rear (yes it affects the radio too, but that is more difficult to quantify). After amp replaced, system is flawless.

So probably amp and not the keys.
