I don't need (or want) a new remote key. I'd just like a separate key fob for the keyless entry. I have three non remote replacement keys that came with my purchase (2 masters and one valet) but no keyless entry. Is it possible to program a Taco or 4Runner key fob to control the keyless entry on my '99 LX? Has anyone tried this with any level of success? Thanks in advance for any and all help.
