Easy Ways to Program Remote Car Keys

Apart from driver comfort, convenience, and overall ride experience, technology has improved security systems in the automobile industry. There is a difference when compared with older systems and models. Now, you can remotely lock and unlock your car doors as well as operate other components such as cooling/heating systems, window lowering, folding the mirror, unlocking the trunk, and more.

Therefore, considering the numerous functions of the car remote, reprogramming or replacement should be a priority when it is defective. The best option is to consult a professional for key fob programming or visit the dealership.

However, we have provided simple procedures for those that want to take the DIY route.

Availability of a Correct Remote Key

Before starting the programming process, it is important to have a new remote that is compatible with your car.

If the new remote has compatibility issues, all your efforts will be in vain. You can purchase a new remote from an auto parts store or a dealership.

Programming a New Remote:

Step 1.

Locate the "Program" button in your car. This button is usually located under the steering wheel, in the glove compartment, or near the shift lever.

Step 2

Insert the key into the ignition and turn it to the "On" position. Then, press and hold the "Program" button until the car's warning lights start flashing.

Step 3

Release the "Program" button and then press the "Lock" button on the new remote. Wait for some seconds for the car's warning lights to flash. This indicates that the new remote has been successfully programmed.


Turn off the ignition and test the new remote to make sure it works properly. In case you want more spare keys for your friends and family members, then repeat the process for each additional remote you wish to program.

Replacing a Car Remote:

The above procedure can also be applied when replacing the car remote. However, you should only replace the remote when the buttons are worn, or the key is malfunctioning. If you are working on a budget, it is better to replace the battery. Here is a simple process:

  • Remove the battery cover by pressing the release button or prying it open with a flathead screwdriver.
  • Take out the old batteries and replace them with new ones.
  • Replace the battery cover and reattach the key ring.
  • Test the remote to make sure it works properly. Hopefully, your remote key will start functioning when the batteries are replaced. But you have to be careful to avoid further damage.

Consult a Professional for Car Key Replacement

Yes, programming and replacing a car remote can be a simple task if you have the right tools and know the correct steps. However, the security system of modern vehicles are complex and may require experience and advanced equipment. That is when you will always need the input of a reliable professional.
