Toyota Yaris Alarm Upgrade

Update 17/03/2017

The Yaris has just had another face-lift. Today I installed a Cobra AK4218 into one and discovered that it looks quite different from the previous version. I’ve now updated my notes to cover the updated specifications.

The AK4218 will work with all new models. GX, SX and ZR. I’ve yet to test the AK4615 but will update this space when I do.

The internals trim remains the same so all photos below remain accurate for the install.

Original Post from 2015…

The first new car to get an alarm installed this year is the Toyota Yaris (XP130) which I got to work on today.

The Yaris comes with keyless entry as standard so both the Cobra AK4218 Toyota alarm or Cobra AK4615 CAN-BUS alarm are the best systems to look consider if you want to retain the use of the factory remote. They also have a factory look and feel to them and are simply in a class of their own.

Here are some photos of what you’ll see after the install:

Cobra Ultrasonic Sensors are a perfect colour match

What if you own an older Yaris?

The Both the AK4218 and AK4615 also work in the XP130 Yaris (2010-2015) and the XP90 Yaris (2005-2010)

All three generations of Yaris come with a factory transponder immobiliser and remote keyless entry as standard.

None of them came with an alarm as a standard option.

    Nice neat job once again Obsessive!

    Really enjoy reading your blog posts on the good and the bad products.

    You simply can’t beat the Cobra 4615 in terms of reliability and quality.

    Keep up the good work!

    Hi Simon,

    It’s more involved then simply purchasing a remote and connecting some wires and is not the sort of job you can do without any skills and experience.
