The Ultimate Guide to Finding the Best Car Key Programming Service

When a digital key is placed into the ignition or brought within distance of a push-to-start vehicle, the car sends out a signal to the key. The key needs to react with a special digital "handshake." If the codes do not match, the car remains a fixed hunk of metal.

- Transponder Keys: These appear like standard metal secrets however have a plastic head consisting of a surprise chip.
