Help identifying aftermarket immobiliser

[Tony351]

I recently purchased a 2020 Transit Custom from British Car Auctions (via relative, but this is a keeper).
The van has an aftermarket immobiliser fitted that I want to remove as I'm concerned if it goes wrong, I'll be stuck.
I've searched the internet but no luck trying to identify it from the transponder (piccies below) , so hoping someone on here may recognise it, this may then help me locate the immobiliser.
I've had half the dash apart but no luck finding it. I've tried contacting previous owner, but no response as yet.

Any help would be appreciated.

Doesn’t look like a modern immobiliser fob, more a door/access fob to me.

I know, except when you press it a small green light illuminates.

When I take it away from the van it will not start until I place the fob back in the van.

I may be going mad and all this is a coincidence, but it is testing!

Just tried again, no fob near van will not start, fob in van will start. Do not need to press fob.
