92 300se Infrared Keyless Entry

[92300SE]

This is a follow up on my initial question(3 days ago),about
buying a used keyless entry remote for my 300SE W140,I
recently purchased with 3 master keys... and no remote.
I purchased a used remote from ebay,for 7$...after receiving it
today,I replaced the 4 battery pack and it seems to be operational,CANNOT be synchronized with my key,it will not work.
Receiver in the door and the remote are good(if I turn the key
in the door the light red/green will start flashing,if I press
the remote button while light is flashing,it will stop for a second,
so,it received the signal,does not open or close the doors...,
fuse in the trunk is fine.There is another fuse someplace else,
maybe under the hood?
