remote woes 1997 W210

[briandownunda]

My remote stopped working on my 1997 E300D.....the car starts fine but the remote will not unlock the doors. I have tried replacing the batteries, reprogramming (per the manual), all to no avail.

Is it possible that something has happened to the remote system on the receiver side? ( I have 2 remotes, and both of them have just stopped working)

Also, does anyone have a link to the procedure for disassembly and replacing of the key in the remote FOB?

Thanks in advance!
