At the top of this page, click on the "Home" tab.

On the right hand side of the page (in blue letters), click on "Do It Yourself".

The second sub-heading is "Chassis".

Halfway down the "Chassis" sub-heading is an excellent article entitled, "W124 Keyless Entry Install". (it's exactly what you're looking for)

Actually, all those DIY articles should be considered assigned reading for any MercedesShop member -- they're fantastic, and an excellent resource.

Good luck,

Jeff Pierce
