PMU-16 integration with remote control module

PMU
1

I’m using a pair of PMU-16s (and dual bridges for windows and lock control) on a show car project. I’d like to be able to provide a remote fob to lock and unlock the vehicle. It seems a 3 button setup could work: 1 button to latch pin 7 of the PMU to turn that on. Then 2 more buttons to lock and unlock the vehicle. I’ve found a bunch of “security” products that do all kinds of things with big antennas and the like, but I’m looking for a small module to provide control inputs to the PMU.

Can anybody recommend something that can support this use case?

Maybe something like this, I have used a 2 channel version, works well

Yes, that’s what I’m looking for. I’ll see if I can get it here in the US.
