Thanks for the video! I have a 1999 S320; the key blade fell out of the fob so I ended up getting a new fob from ebay, replaced swapped the chip over to the new key, and now gonna get the new key blade cut. Thanks for the info on the circuit board and chip!!

this is a update i just opened the fob back up and checked all connections and they were all fine, so i check the batteries one by one they were fine. are you ready for this together the batteries were not making contact my problem ended up being the battery lost connections some how between each other i rubbed them against each other firmly and boom the batteries made contact now remote is working go figure😊.
