Techniques of Reprogramming Keys
Reprogramming Car Key keys can vary considerably based on the make and model of the vehicle. Below are the most typical techniques for reprogramming car keys:
MethodDescriptionOnboard ProgrammingSome vehicles permit key reprogramming via the ignition switch without unique tools.Diagnostic ToolExpert mechanics typically use diagnostic tools to interface with the vehicle's ECU.Transponder ChipVehicles equipped with transponder keys require special programming of the key's chip.Key Programmer DeviceSpecialized devices are available for purchase that can reprogram various types of keys.Onboard Programming
Onboard programming includes following a series of steps with the vehicle's ignition system. Although not appropriate for all designs, the procedure normally follows these actions:
Insert the initial key into the ignition and turn it to the 'On' position (do not begin the engine).After a few seconds, turn the key back to the 'Off' position.Repeat this treatment within a particular variety of seconds (examine the owner's handbook for precise details).Turn the vehicle to the 'On' position once again with the brand-new key you want to program. The security light will flash to show the new key has actually been accepted.Diagnostic Tool Method
For more complicated reprogramming, it may be essential to use a diagnostic tool, especially for more recent cars. This is often done by an automotive technician. The actions normally involve:
Connecting the diagnostic tool to the vehicle's OBD-II port.Selecting the choice for key programming.Following on-screen directions to input brand-new key information into the vehicle's ECU.FREQUENTLY ASKED QUESTION: Reprogramming Keys for CarsQ1: Can I reprogram my car keys myself?
