Keyless Entry for a 560SEL.
 

Is it even remotely possible to put a keyless entry system on a W126? I see a kit on ebay which claims to fit all MB's, and has flip remote-keys that look somewhat similar to the newer Smart Key used on late model MB's. How hard would that be to install on my 86 560, or is it an impossiblity. Both my 94 Cadillac and my 94 Lincoln Town Car have keyless entry systems, and I find them very convenient (especially the remote trunk release :) ).
Thanks, and God Bless,
Dave.

Dave,

Very possible and not that hard.

For a general overview of what's involved take a look at this link. Click on "Stereo/Alarm Updates" and browse down the page.

Depending on the kit you buy you need to modify your current key to fit the flip blade you purchase.
