This is completely new stuff to me. I've got a 2003 Element I just purchased that has lost function of the door tumblers (common problem) so the keys don't lock/unlock the doors. The seller included a remote starter that he said I could wire up to act as a key-less entry. I know that if I were to wire it all up with the remote-start function, I would need to install and program a by-pass module. I don't need that and would rather avoid the cost for this beater. Is it possible to just wire it up enough to have it function as a key-less entry system? The car already has working actuators from power locks.

The system is a Prostart CT-3371

Any advice would be appreciated.
