Why Your Hardware-Store Copy Won't Start the Car

Transponder car keys and a key programming tool
A small chip in the key head talks to the car's immobilizer.

Since the late 1990s, most cars have a small transponder chip in the head of the key. When you turn the ignition, the car checks that chip, and if it doesn't recognize it, the engine won't start (or starts and dies). That's why a plain metal copy from a hardware store may open the door but won't run the car.

What We Do

  • Cut the blade (standard or laser-cut)
  • Program a new chip to your car's immobilizer
  • Clone an existing chip where the vehicle allows it
  • Add spare keys
  • Replace keys when all are lost
  • Diagnose "security light" no-start problems

Signs of a Transponder Problem

A flashing security or key light on the dash, a car that cranks but won't fire, or an engine that starts and immediately shuts off can all point to a key the car no longer recognizes. Sometimes the chip is damaged, and sometimes the key just needs to be reprogrammed. We can test it on site.

Frequently Asked Questions

How do I know if my key has a chip?

If your car is from roughly 1998 or later, it very likely does, especially if the key has a thick plastic head. Tell us the year, make and model and we'll confirm.

Can you copy my chip key without the car present?

Some chips can be cloned from your existing key. Others must be programmed at the car. We'll tell you which applies to yours.
