Best OBD2 Scanners for Key Programming (Actually Worth Buying)
Published: July 20, 2025 · Last updated: April 16, 2026
If you need to add new key, create key from scratch (“all keys lost”) or perform other key service procedure, you will need right OBD2 scanner. It must have key-programming features and support your car model.
I earn from qualifying purchases and sometimes get tools for free (full disclosure). It never affects my scoring.
Quick recommendations for key work
Warning: To sucesfuly perform key programming, you must have a tool that supports your car model. I recommend contacting XTool support with car model or VIN number to confirm which of their key programmers will do the job.
