Techniques of Reprogramming Keys

Reprogramming keys can differ substantially based on the make and design of the vehicle. Below are the most typical methods for reprogramming car keys:

Method

Description

Onboard Programming

Some cars enable key reprogramming via the ignition switch without special tools.

Diagnostic Tool

Expert mechanics frequently use diagnostic tools to interface with the vehicle's ECU.

Transponder Chip

Vehicles geared up with transponder keys need unique programming of the key's chip.

Key Programmer Device

Specialized devices are readily available for purchase that can reprogram different types of keys.

Onboard Programming

Onboard programming includes following a series of steps with the vehicle's ignition system. Although not relevant for all models, the process generally follows these actions:

  1. Insert the initial key into the ignition and turn it to the 'On' position (do not begin the engine).
  2. After a few seconds, turn the key back to the 'Off' position.
  3. Repeat this treatment within a specific variety of seconds (check the owner's handbook for exact details).

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

FAQ: Reprogramming Keys for Cars
