Car Immobilizer Repair in NJ

Keep Your Vehicle Secure, Start-Ready & Theft-Protected

Your car’s immobilizer system is a key anti-theft feature designed to prevent unauthorized starting of the engine. When this system fails, even a valid key may not start the car—leaving you stranded or frustrated. Whether caused by a faulty transponder chip, damaged wiring, or a failed control unit, immobilizer issues need expert attention. At Three Brothers Auto Repair Service, we offer professional car immobilizer repair across NJ to get you back on the road safely and securely.

Signs Your Immobilizer Needs Repair

• Car won’t start, even though the battery and starter are fine

• Key symbol flashing or staying lit on the dashboard

• “Key not recognized” or similar warning messages

• Engine cranks but doesn’t fire

• Inconsistent start behavior with the same key

• Need to use backup or manual override repeatedly

If you experience these problems, your immobilizer may be blocking ignition due to a communication failure between the key and vehicle ECU.
