What is this Emergency Key Card for?

[68c]

Found this cardboard Emergency Key Card in my paperwork, the reverse has a four digit PIN code and instructions to enter the code by turning on and off the ignition then counting LED blinks.
Our van is a 2001 Pilote G270 with a 2.8Hdi engine.
Any idea what system that is for? As far as I am aware we have no burglar alarm although there are what looks like two ultrasonic detectors set into the front coaming/dash board surround.
Do not want to play with it in case I end up not being able to start.

Looks like alarm / security override.

Delta Electronica make alarms for vehicles including motorcycles

Thanks all, so is it a Peugeot fitted thing or aftermarket? Or fitted by Pilote?

Peugeot..... Usually for the European Market I think as UK insurers don't approve.
We, in the UK, would normally have to contact your dealer with proof of ownership to get the code.
