Following closely—this could be the fix I need for my 2012 Toyota Harrier.

Thanks! This could save me a trip to the dealership for my 2012 Toyota Harrier.

Appreciate any advice—my 2012 Toyota Harrier won’t recognize the key.

I have the same 2012 Toyota Harrier and I'm also trying to find the key code.

This is gold. I’ve been locked out of my 2012 Toyota Harrier for days.

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
