However, regardless of whether I connect the door lock trigger to 85 and the power to the 86 or vice versa when I hit the fob button to send the signal, nothing happens.
Tested the remote system (i.e. lock/unlock triggers) with a test light and pushing the button completes the circuit, looks like that's working fine.
I'm probably being a numpty and missing something, so I got my mate (who used to do sound/alarm system installs for a living) to have a poke at it for me, he came up with the same thing.
The only thing I can think is that the Relay is the wrong type (Normally Open vs Normally Closed?), or is cactus.
Am I missing something?

The relay has to be a "changeover" type relay. Most are changeover,
but if you have the other type with 2 output contacts then it will
not work.
The changeover relays have a normally open contact AND a normally
closed. Its the normally closed contact that you're using in this
scenario.
I will also PM you my details.
