IMMOBILIZER & KEY DIAGNOSTICS

Key Not Working? Immobilizer Problems?

Modern vehicles rely on electronic immobilizer systems, transponder keys, smart keys, and remote key fobs to authorize starting the engine. When these systems stop communicating correctly, your vehicle may not recognize the key or allow it to start.

CarKey+ specializes in diagnosing automotive key, immobilizer, and remote programming issues. We identify whether the problem is the key, key fob, immobilizer system, or programming—then provide the correct solution on-site.
