🚗 Replacing and Reprogramming Acura Key Fobs: A Complete Guide

If you're facing issues with your old Acura key fob, or simply want to upgrade to a new one, you've come to the right place! In this article, we will walk you through the process of replacing your existing key fob with a new one and reprogramming it. With the help of clear instructions and step-by-step guidance, you'll be able to effortlessly complete this task. Before we dive into the practical steps, let's learn a bit more about the background and tools needed for the job.

Background

1. Issue with Old Key Fob: Are your key fob buttons worn out or faded? Maybe the electronic module is no longer functioning properly. Whatever the case may be, it's time for an upgrade.
2. Upgrading to a New Key Fob: You've decided to replace your old key fob and have purchased a Chinese replica of the plastic case. However, you've encountered some challenges during the transition. Don't worry, we'll guide you through the process and help you overcome any obstacles.

Tools Needed

Before we begin, let's make sure you have all the necessary tools to complete this job successfully. Here's what you'll need:

1. Small Phillips screwdriver
2. Sharp plastic or steel knife instrument

Make sure you have these tools handy before you proceed with the replacement and reprogramming process.

Migrating the Old Key to the New Key Fob

The first step involves transferring the old key to the new key fob. Let's get started by opening up the old key fob and removing the transmitter and battery.

1. Opening the Old Key Fob: Locate the screw holding the cover of the old key fob and remove it. Use a plastic tool to gently pry open the cover and pull it off.
2. Removing the Transmitter and Battery: Using a sharp tool, carefully pry the transmitter from the cover. You may notice a spot where it's easy to insert a prying tool and open the transmitter. Take out the battery if replacement is needed (CR1616).

Now that you have removed the necessary components from the old key fob, let's move on to the next step: removing the old key itself.

Disassembling the New Key Fob

To properly transfer the old key to the new key fob, we need to disassemble the new key fob. Follow the steps below:

1. Opening the New Key Fob: Using a plastic tool, open the new key fob in the same manner as the old one. Find a spot where it's easy to insert the prying tool and carefully open the transmitter.
2. Removing the Metal Piece and Spring: Once you have opened the new key fob, you'll notice a metal piece holding the key. Remove the two screws that secure the metal piece. Take note of the metal spring that sits behind the metal piece.

With the new key fob disassembled, we can now proceed to transfer the old key.

Transferring the Old Key to the New Key Fob

Now comes the exciting part – transferring the old key to the new key fob. Let's go step by step:

1. Inserting the Old Key: Carefully place the old key into the new key fob. Ensure that the bigger side of the key plastic base is on the left and that it clicks securely into place with the key extended.
2. Placing the Spring and Metal Part: Insert the metal spring into its socket on the left side of the key fob. The spring should sit firmly in the socket, with the straight part of the spring left free. Carefully position the metal part on top of the spring, approximately 90 degrees rotated from its original angle. Insert the free straight part of the spring into the designated hole. Finally, turn the metal part 90 degrees clockwise to align it with the screw holes and secure it in place.
3. Securing the Key in Place: Fold and unfold the key to ensure it clicks and locks securely. To do this, hold the metal part firmly with one hand and put in and tighten the screws with the other.

Congratulations! You have successfully transferred the old key to the new key fob. Now, let's proceed with the reassembly process.

Reassembling the Key Fob

It's time to put everything back together. Let's reassemble the key fob step by step:

1. Putting the Cover Back On: Attach the second part of the cover, ensuring it clicks into position and sits flush with the bottom part.
2. Reattaching the Transmitter: Put the first part of the cover back in place, following the same order as when you disassembled it. Click it into position firmly.
3. Tightening the Screws: Use your small Phillips screwdriver to secure the cover by tightening the screws.

With the key fob reassembled, it's time to move on to the next crucial step: programming the key fobs.

Programming the Key Fobs

Before you can use your newly replaced and reassembled key fob, you need to program it to work with your Acura. Here's a detailed guide on the programming process:

1. Step-by-Step Programming Process: Follow our step-by-step guide to successfully program your key fobs. This process includes turning the key in the ignition, clicking the unlock button, and confirming the programming by repeating certain steps.
2. Testing the Programmed Key Fobs: Once the programming process is complete, it's important to test all the buttons on all the programmed key fobs. Ensure that each key fob is functioning properly, including features like the power liftgate.

Congratulations! Your key fobs are now successfully programmed and ready to use. Now, let's explore some additional tricks you can do with your key fob.

Additional Tricks with the Key Fob

Aside from regular functionality, your Acura key fob has some hidden tricks up its sleeve. Let's discover them:

1. Disabling Driver Memory Feature: If you don't want the key fob to restore driver memory settings for each user, simply press and hold the lock and unlock buttons simultaneously until the red LED blinks.
2. Rolling Down Windows and Opening the Moonroof Remotely: Want to let in some fresh air before stepping into your car? Click the unlock button once and then press and hold it to open all the windows and the moonroof remotely. Unfortunately, closing all the windows remotely is not possible unless you modify your vehicle. However, you can achieve it by turning the key in the driver's door lock.
3. Closing Windows and the Moonroof Using the Key: Insert the key into the driver's door lock and turn it counterclockwise, release, and turn it counterclockwise again. Hold the key in this position to close all the windows and the moonroof.

With these additional tricks, your Acura key fob becomes even more versatile and convenient to use.
