How to program a car key

Automotive technology has changed significantly over the last 30 years. The car locking/unlocking system and security are areas where the most notable changes have taken place. Today's cars are equipped with computer technology, which enhances your car's protection. However, they require chip-integrated keys that must be programmed into your vehicle. This system is an excellent way to deter car thieves. Yet, where there is a plus, there is sometimes, unfortunately, a minus as well. Because of this new technology, getting back into your car can be more time-consuming and challenging, even for a professional locksmith. Without the microchip, the car won’t start. Plus, the key programming process may be unfamiliar to people who have never dealt with something similar before.

In this article, we will answer the key questions about car key programming to help you understand your options when your key stops working.

Start with the Basics: Check Your Key Fob Battery

Before learning how to program a car key, it’s important to check whether a simple battery replacement can resolve the issue. In many cases, a non-functioning electronic key fob does not need to be reprogrammed or replaced completely. So, before spending a fortune on a new key fob, check if a simple battery replacement resolves the issue.

First, open the key fob and find a tiny "key" embedded in the seam of the device. Once located, pull out the key and use it to carefully pry the case open. Take your time to avoid damaging the case. Once opened, you will see the circuit board inside. Carefully remove it to reveal the battery at the bottom.

Most key fobs use a small clock battery, which can be found at most home improvement stores. These batteries typically cost just a few dollars, so it’s a good idea to replace the old one with a fresh battery before considering replacing the entire fob.

Can I Program My Own Car Key By Myself

Some vehicles allow you to program your own key or key fob, and programming instructions are often included in the vehicle service manual. Note that many vehicles enable you to program the remote part of the key (to open the doors or trunk) but not the key itself. Thus, you will be able to open the doors/trunk, but the car will not start until the key is connected to the car's computer for programming.

However, as a rule, you might not reprogram a car key yourself. Very few models allow this, and it often depends on the country and the manufacturer. While this may seem unpleasant, it also prevents other people from reprogramming the key and stealing your car. So, don’t be upset that your car doesn't allow you to do that. As you can see, it may be best not to risk reprogramming the key yourself but to have it done professionally.

For those vehicles that do allow DIY programming, here’s a step-by-step outline:

1. Insert the Original Key: Insert the already-programmed key into the ignition and turn it to the "On" position without starting the engine. Leave it in the "On" position for a few seconds.

2. Remove the Original Key: Turn off the ignition and remove the original key within the time frame specified in your vehicle’s manual.

3. Insert the New Key: Insert the new key into the ignition and turn it to the "On" position. Some vehicles require you to press specific buttons on the key fob, such as "Lock" or "Unlock," during this step.

4. Cycle Through Programming Mode: Follow any additional steps outlined in your manual, like cycling the ignition Off/On a certain number of times or pressing buttons on the fob in a specific sequence.

5. Complete Programming: Leave the new key in the "On" position for the time specified in your manual.

6. Test the Key and Fob: Turn off the car and test both the ignition and the remote functions of the new key to make sure the process is successful.

Where to Get Help with Car Key Programming

You can visit a certified dealer of your car manufacturer or key programming locksmith, i.e., an automotive locksmith, for help with key programming. Both of them are perfectly capable of providing you with a new key, programming it, or repairing the old one.

Locksmiths that program car keys use the vehicle identification number (VIN) to make sure you get the right key. The VIN number can be found on most official documents, including the vehicle's title, registration, and insurance cards. You may also find it by looking through the windshield on the right side of the dashboard.

When to Call an Automotive Locksmith?

Programming a key fob is often not a straightforward task. Most modern vehicles require specialized tools and software to connect the key fob to the car’s computer system.
