The site works, shows how to do it, but not what it takes for batteries. I have the newer style, and my older style is with the car at MB this week. I hope you are discussing the big boxy remote, it should have a 129...etc part# and was introduced in 91 for the SL and is the size of a zippo lighter with no key ring loop. When I got my 140 there was one of those in the owners manual and the dealer provided two more remotes half that size, which were a running replacement, their part# starts with 140.... etc. usually use the old one for valet/dealer. I have never replaced those in mine.
