94 w124 - Keyless entry

[jm124]

I wanted to get a keyless entry system installed. Went to a guy who deals with alarmsystems and audio equipment. He said that its already installed and i just need to buy the remote for $150. But i called MB and they said there is nokeyless entry option for the car.
can anyone confirm this?

Also there is no CD prewire in the trunk. I thought that all 94 w124's w/ M104 engine had a prewise

How do i take off the trim in the trunk near the hinges without breaking any clips?
