Which is better for a 2015 GMC Terrain?

Both fit a key-start 2015 Terrain. The Fortin EVO-GMT1 is cheaper and uses your factory key. The Start-X kit gives you a separate remote with 3,000 ft range for $199.00.

Is the Start-X kit worth the extra money?

Only if long range matters to you. You pay about $123 more than the Fortin for a dedicated fob and 3,000 ft range instead of factory key range.

Do I need to give up my factory key with the Fortin?

No. The Fortin starts the car with your existing flip-key remote using 3X LOCK, so there is no extra fob.

Will either kit work on a push-button-start Terrain?

No. The Fortin is for select flip-key GM vehicles and the Start-X kit is for key-start 2010-2017 Equinox and Terrain.

Which one is easier to install?

Both are plug-and-play with a vehicle-specific harness. The Fortin adds on-board LEDs for programming and diagnostics, which helps if something goes wrong.

Does the Fortin add security features?

Yes. It includes an alarm system and doorlock interface along with the remote start, which the Start-X kit does not list.
