Key Light Help

HELP MY CAR WONT START AND I'VE GOT A BLINKING LIGHT ON MY DASH!!!

Common Causes

 

If all else fails, you can count on the Pros @ Mr. Key Pro to get you back on the road in no time!

The transponder chip in the key may be damaged or not programmed to the vehicle.
If using a new or duplicate key, it may need to be programmed.

If your car uses a push-to-start system, a weak key fob battery may prevent the immobilizer from detecting the key.

The immobilizer antenna (ring around the ignition) may be malfunctioning.
A communication issue between the key and ECU can trigger the warning light.

Damaged wiring between the immobilizer system and ECU can cause a failure.

Poorly installed or malfunctioning aftermarket security systems can interfere with the immobilizer.

A software glitch or hardware failure in the vehicle's ECU or BCM can cause the immobilizer to malfunction.

What can I do to try and fix this myself?

Here's what you can do!

If you’ve ever encountered an Immobilizer light on your dashboard, and your car wont start, there’s a few things you can do to try and diagnose the issue.

If available, use a different key to determine if the issue is key-related.

If using a push-to-start system, change the battery in the fob. 

Try flipping the battery around the other direction as it may have been installed backwards.

 

  • Exit the vehicle and lock/unlock the doors with the key fob.
  • Insert the key into the ignition and turn it to the "ON" position for a few minutes.
  • Remove the key and try starting the car again.9 

A weak car battery can sometimes cause immobilizer failures.

If you've made it this far, then your probably still facing the same immobilizer issue
