98 S420 remote programming
 

would someone please post the programming instruction for the 98 S420? this is the 3 button switch blade type key. I did not find anything on this forum. if memory serves right it was something like, hold one of the buttons then lock/unlock driver's door 3 times, then release ...... or something close to this. any assistance is appreciated.

this is a repost, from an earlier incorrect posting -
