Hi, wish I could help, I'm stuck with exactly the same problem. Have you had any luck yet? Thought it would be easy but looks like I'm gonna have to call a pro in unless someone on here can help? Cheers.

I hope that's not a Cane Toad.

The IR remote lock and unlock inputs to the central module are both positive trigger. To double-lock the car, you pulse both simultaneously: most people use a couple diodes. I believe you will find your central module, either a central locking module (ZVM) or a central electronics module (ZKE), behind the glovebox.
