This eternal question is one that doesn't have a simple answer. It is technically possible to switch a remote starter to another vehicle; but be sure to prepare yourself for a whole load of hassle along the way. Here's a list of some complications which may arise below. Interface: The technical workings of a modern car are advanced yet also incredibly specific. A vehicle interface is a piece of hardware that connects to the car's control area network and is why modern cars are so advanced. However, not many vehicles have the same interface to prevent car thief. If your vehicles don't take the same interface, you'll have to buy a new remote car starter. Warranty: When it comes to any remote car starter, having the correct warranty is a top concern. It's very rare that remote starter manufacturers will warrant more than one vehicle; removing the starter from one vehicle and installing it into another essentially makes the initial warranty null and void. Check your remote car starter's warranty before taking any risks. Money, Money, Money: You may think that investing in switching a remote car starter from one car to another is a bold and cost-effective move. However, the additional charges will have you sprinting to your nearest hardware store. As well as paying to have the system removed, you're paying to have it reinstalled with a number of potential complications which could easily arise - waiting to rob you of even more money. All in all, we'd recommend steering clear of this misery and treating your new vehicle to a contemporary system with fewer potential complications.
