1. Connecting the diagnostic tool to the vehicle's OBD-II port.
2. Selecting the choice for key programming.
3. Following on-screen instructions to input brand-new key details into the vehicle's ECU.

FAQ: Reprogramming Keys for Cars

Q1: Can I reprogram my car keys myself?

A1: Yes, depending on the make and model of your vehicle, some cars enable for onboard programming that you can perform yourself. Nevertheless, for many more recent designs, using expert services or diagnostic tools may be necessary.

Q2: How much does it cost to reprogram a car key?
