Clear Help for Automotive Locksmith
Modern car keys can contain a metal blade, transponder chip, remote board, proximity system, or several of those parts in one housing. A correctly cut blade may open the door but fail to start the engine until its chip is programmed to the immobilizer.
Before dispatch, gather the VIN, registration, photo identification, year, make, model, and key style if possible. That information helps identify the correct key blank and programming path. It also allows the locksmith to flag models that need special codes, modules, or dealer involvement.
