My original alarm no longer works--for what reason, I have no idea. To get to the point, I called the closest Benz servicer and they told me 100 just for looking @ it + any needed parts + labor. So I think I'm going to opt for the cheaper approach of going to a professional installer. Right off the bat, he said he could install a system, but due to the *vacuum*, the keyless entry function would not work... So, I took it to another guy. He immediately said the vacuum would pose no problem. Is the second guy *****ing me?

I would like to have keyless entry + an alarm, but not with the colossal price attached to it.
