Everything You Need to Know About Key Fob & Transponder Programming
Do replacement car keys come with a warranty?
Yes. Every key we cut and program comes with our workmanship guarantee. If the key fails due to our work, we'll fix it at no charge. The physical key blank and transponder chip carry their manufacturer's warranty as well. Our Greenville technicians carry all necessary equipment on-board.
Can you make a key from my VIN number?
Yes. With proper ownership verification, we can use your VIN to determine the correct key cut and transponder programming for your vehicle. This is how we create keys when you've lost all copies — no original key needed. This is one of our most requested services in the Greenville area.
Do you service hybrid and electric vehicle keys?
Yes, we program keys and fobs for most hybrid and electric vehicles including Tesla Model 3/Y key cards, Chevy Bolt, Toyota Prius, and Hyundai Ioniq.. EV key technology uses the same transponder principles as conventional vehicles.
My key turns hard in the ignition. What's wrong?
This usually indicates a worn ignition cylinder.. If ignored, it can leave you stranded when the key stops turning entirely.. We can repair or replace your ignition cylinder on-site.. Most repairs take about an hour.
Should I get a spare car key made?
Definitely. Getting a spare now is a highly recommended safety measure compared to what you'll experience during an emergency lockout. Plus, programming a spare is simpler and more straightforward when you have a working key to reference. We bring this expertise directly to your location in Greenville.

How Transponder Keys Work
