The key has an RFC chip in it, the battery shouldn’t have any effect on it’s ability to start. Same reason why a “Mickey Mouse” key will start and run the car as well.
Just for grins, try the remote at each door and the trunk in the dark. I say that because my 1997 SL500 fob won’t work in the daylight, but will in the dark. I can only assume that something has weakened the fob (this is with brand new batteries) or the system isn’t as sensitive as it used to be. -D > On Aug 9, 2019, at 4:11 PM, Floyd Thursby via Mercedes > <mercedes@okiebenz.com> wrote: > > Last week I thought I had locked the SL with the IR remote that shines at > receivers on the doors and trunk.
