# Best key programming scan tools for home use Source: https://codeandclear.com/best/best-key-programming-tool Publisher: Code & Clear. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://codeandclear.com/how-we-pick Key and fob programming is the area where scan tool listings promise the most and vary the most. Whether a tool can add a key to your car depends on the make, model, year and immobilizer system. Some newer cars also need a security credential before any tool will do the job. A tool that programs keys on one car may do nothing on the next. This guide compares five listings that name key programming, key fob kits or immobilizer support. We compare what each listing actually states about key functions, what is in the box, any account or credential requirement the listing mentions, and the update terms. Several listings describe their key functions only in broad terms, and we say so. Before you buy any tool here, check the listing's vehicle coverage list for key programming on your exact car. If you cannot confirm it, a locksmith or dealer may be the safer path. ## Picks ### 1.
