Programming Keyless Entry Fob

[SlyPerez]

The one I was using in the back says:
1L2T-15K601-AA
FCC ID: CWTWB1U322
CAN: 1788 102 354

The one I bought:
2L2T-15K601-BA
FCC ID: CWTWB1U331
CAN: 1788 104 575

I did exactly as you said, nothing happened.

A couple of sites I looked at imply that those two remotes are no necessarily compatible. I'm not sure if/why that would prevent you from being able to program the original one that used to work.

Have you tried programming each one separately to see if they both work individually? Go through the process but only program the remote that you know used to work. If that works fine, then go through the process for the "new" remote and see if it works. If the original will program and work, but the new one will not, then you probably can decide the new one is not compatible and reprogram just the original again.

FWIW, it appears the first digits of the Ford part number are most significant. I checked three remotes I have sitting around here and the first 4 digits are the only ones that are different.
1998 Taurus SHO -> 2S4T-15K601-AA
2000 Mountaineer -> F8DB...
2002 Lincoln LS -> 2S4T...

Hey SlyPerez I have been currrently having the exact same problem with programing my keyless remotes with the exact same car and exact same two remote codes. I have tried entering or program mode various time and nothing occurs when I press the button on the remotes. did you ever fix or resolve this problem
