Mitsubishi Lancer Alarm Options:
The final incarnation of Mitsubishi Lancer ran from 2007 until it ceased production in 2017. It came with a key-less entry and immobiliser as standard.
Note that the Japanese import models were branded as a Mitsubishi Galant Fortic, but are effectively the same car.
With the exception of late the model EVO X, the Lancer did not come with an alarm, therefore, I highly recommend the Cobra AK4615 CAN-BUS upgrade alarm if you want to beef up the security. The AK4615 works flawlessly with the factory remote and has the option of an ADR card if you want to protect against key-less theft!

Smart Key
If you have a keyless ignition I recommend adding an ADR card to the Cobra AK4615 to protect against OBDII hacking and Relay attacks.

Window Closure and Mirror fold comes as standard
The Lancer comes with remote mirror fold and window closure which can be activated with an extended 2nd press of the factory remote control. The Video below shows how the alarm works as well as the window closure in action:
Here are some photos of what the alarm looks like installed:
