I am selling the original keyless entry system that was installed on my
1999 Sonata GLS (Clifford supplied system). It would probably work with
the 2000-2001 as well (as they are all virtually the same vehicles). It
comes with 2 remotes (1 is brand new, only used to program it) the keyless
module, and the wire harness (to plug and go with no soldering or wire
tapping needed)... You can get install and programming instructions from
HMA webtech2000. The only thing I am not including is: Peizo speaker.
