How Auto Locksmiths Cut and Program Car Keys on the Spot

But how do they do it? Let's break it down.

Step 1: Identifying the Vehicle Model and Key Type

The first step is to determine the kind of key you need. Modern vehicles have different types of keys, i.e. smart key, transponder, remote fob, and standard metal keys. No worries if you cannot figure this out, as the locksmith will find out.

Step 2: Cutting the Key

The auto locksmith will proceed to cut the new keys. This will require the use of a key-cutting machine, particularly in case of traditional car keys. Then, the locksmith inserts the original key or key code and the machine gives a duplicate using the grooves of the original key.

However, the process is more complex in newer vehicles that have transponder chips or smart keys. These keys have an inbuilt chip that links to the immobilization system on the car. So, to make keys with the precisely integrated chip and grooves needed by modern security systems, GreenPro Locksmith uses highly advanced key-cutting devices.

Step 3: Key Programming

Cutting the key is just half of the job. The next thing for remote key fobs or transponder chips is programming. This will enable the key to communicate with the vehicle's electronic system. The programming process requires a specific set of tools, with the majority of locksmiths always having them in their toolboxes..

For transponder keys, the locksmith in Marietta, GA makes use of a high-level programmer, which links directly to the onboard diagnostic port (OBD-II) of your vehicle. They enter the vehicle data into the immobilizer system and program the new key to the car. The chip needs to be linked to the car computer system so that the key will be recognized as a valid access device.

But for a remote fob and smart key, the radio frequency of the car needs to be matched with the key to activate the car engine when it is inserted or when a push-to-start button is pressed.

Step 4: Testing and Final Changes

This is the final process. Here, the locksmith tests the key to be sure if the lock and unlock works well and whether it is performing any other functions, such as trunk opening or remote start activation.

If any issue is detected, the locksmith will reprogram the key or make the adjustments needed so that the key will be fully compatible and work with your car system. This is a service that will be rendered on-site, and for this, you won't have to travel all the way to a dealership or locksmith shop.
