Mazda 3 Upgrade alarm

The Mazda 3 (Or Axela as it is called in Japan) was first released in 2003. All New Zealand models have a factory immobiliser but some of the early Generation 1 Japanese Axela (BK Shape) imports did not have any form of security.

With all Mazda 3 models adding an alarm to the work with the factory remote controls is possible.

I’ll start off with the GEN 2 (BL) model which is full CAN-BUS and really does need a decent CAN-BUS alarm if it is to be effective.

The 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. Therefor most aftermarket CAN-BUS alarms can be tricked into arming and disarming which is clearly not ideal.

The only CAN-BUS alarm I am currently aware of that protects against this is the Cobra AK4615. It is the only system I recommend for the BL Mazda 3/Axela if you wish to continue using the factory remote or smart key. The Cobra has that factory look and feel too so it’s simply the best choice. There is also the option to add a Cobra remote control which is far better value then the $300+ that Mazda normally ask for a single remote.

For those of you that don’t have any factory remote controls a Remote Upgrade Alarm or keyless entry system is recommended.

Here are some shots of how the Cobra AK4615 looks in the car:

Hooking the horn up along with the Siren up is easy with the AK4615 on the Mazda 3. Everything other then the Ultrasonic sensors and the LED are hidden.

The Cobra AK4615 also works with the original Gen 1 Mazda 3, but it is in PLIP mode rather then CAN-BUS. From a user point of view it still functions the same.

As the BK Model does not need a CAN-BUS alarm any OEM upgrade alarm can be made to work, as can a Remote Upgrade Alarm if you need an alarm with it’s own remote controls.

Below are some photos of a Gen 1 Mazda 3 installed with a Cobra:
