"The bypass unit is 3545333, bottom right of the following photo."


@Tydoggroyal is this making sense?
I have the fob you have pictured. I had an aftermarket central locking which I removed and installed Volvo 850 Security Theft Lock MODULE 850 Pn 3545654 oem. So I need to remove the Starter circuit (bottom right) what do I replace it with?

Does the dash Red LED work with the setup you currently have?

I don't think you need but replacing the starter circuit with the red alarm relay works for me.

I think this is the wrong FOB the ebay listed will work.

The 2 button fobs are the same as mine

I don't have the red light on the top of the dash working .
The red light worked on the old aftermarket Australian module
The red anti-theft relay is that under the steering column ?
.

Yes.

I would say you have the starter circuit in there.

Get the alarm relay VOLVO 9128903 and the 3545653 fob there are a few on eBay. It will then work
I purchase the fob that you posted on ebay. Will track down a relay now.
