The 2nd generation Mazda MPV comes with keyless entry and a factory immobiliser but lacks an alarm
Most other alarms I have tested on the MPV can be tricked into disarming without the remote and are simply not very effective.

The MPV CAN-BUS system is similar to most Nissan models in that a manual lock/unlock with the hazard lights active produces the same signal as a remote lock/unlock. The AK4615 is not vulnerable to this trick.
Here are some shots of how the Cobra AK4615 looks in the car:
The Cobra AK4615 also works with the original Gen 1 Mazda MPV (2000-2006) in PLIP mode.
Expect horn honk as standard.
