Audi A3 Replacement Key

Friday, 24 June, 2022
 

When your Audi key fob stops working, it's more than just an inconvenience — it disrupts your day. It could be a dead battery, physical damage, or simply misplacing the device, which can be frustrating. So, how do you replace the Audi key fob?  This comprehensive guide will walk you through the process of replacing your Audi key fob so you can quickly regain access to your vehicle.

Understanding Audi Key Fob Technology

Audi key fobs, particularly the Audi Advanced Key system, utilize a combination of proximity detection, keyless entry, and personalized settings. Here's how it works:

  • Proximity detection: When you approach your vehicle, the Audi key fob communicates with the sensors to activate the keyless entry system. This lets the vehicle recognize the fob.
  • Keyless entry: When you hold the door handle, the car's sensors detect the fob and unlock the doors automatically. 
  • Authentication: Upon activation, the key fob sends a unique authentication code to the vehicle's onboard computer. This adds a layer of security, as no other key fob can unlock or start the vehicle.

Step-By-Step Process for Audi Key Fob Battery Replacement

In many cases, a malfunctioning Audi key fob can be resolved by simply replacing the battery. Follow these steps to change the battery in your key fob.

Identify Your Audi Key Type

Find out  which type of key fob you have, since different models need different battery types. Most newer models and smart keyless entry systems use CR2032 batteries, while older models use CR1620. 

Locate the Release Button

Gather tools such as a small flathead screwdriver or a coin to open the key fob. Most Audi key fobs have a small release button on the back side that allows you to access the internal battery compartment. 

Access the Battery Compartment

Press the key release button to remove the metal key blade if you have a smart keyless entry system. Look for a small notch where the metal key was located and use your screwdriver to gently pry open the fob. For flip key fobs, you need to flip open the metal key using the release button. Use a flathead screwdriver to carefully pry apart the two halves of the fob, starting from the notch near the metal key.

Remove the Depleted Battery

Once you have access to the battery compartment, take out the old battery. Note the orientation of the positive and negative terminals to replace the battery.

Insert the New Battery

Place the new battery into the housing, and make sure that the positive and negative terminals are aligned correctly. The positive side should face down for a CR2032 battery. 

Reassemble the Key Fob

Snap the two halves of the key fob casing back together, making sure that all components are securely in place. You may have to reinsert the metal key blade into its compartment.

Test Your Key Fob

Press the buttons on your key fob to verify that it is working properly. If the issue persists, you may need to consider a full key fob replacement.

Options for Obtaining a Replacement Key Fob for Your Audi

When a battery replacement doesn't solve the problem, or if your key fob is lost or damaged beyond repair, you'll need to obtain a replacement. There are several options available:

  • Audi dealership: The most straightforward way to replace your Audi key fob is to visit Audi Mission Viejo. Our technicians use the necessary equipment to program a new key fob specifically for your vehicle.
  • Online options: Online retailers offer a wide selection of key fobs, which would still need to be programmed by a professional. However, there is a risk of receiving counterfeit or incompatible products when purchasing online.

Avoiding Common Mistakes When Replacing Your Audi Key Fob

Here are some considerations when replacing your Audi key fob:

Verifying Compatibility

Always confirm that the replacement key fob is compatible with your specific Audi model and year before making a purchase.

Understanding Key Fob Replacement Costs

Many dealerships charge $400 to $800 for key fob replacement, including programming fees. You may be tempted to consider aftermarket options that cost $20 to $50. It's important to remember that they often come with risks, such as incompatibility or failure to program correctly.

Choosing the Right Service Provider

Choose a certified technician who is familiar with your specific Audi model. Most Audi keys are paired to the vehicle identification number at the factory, so they need to be programmed by a dealership.  

Using High-Quality Batteries

When replacing the battery in your key fob, opt for a premium, long-lasting option from a reputable brand to minimize the risk of future issues.

FAQ and Troubleshooting Common Issues With Audi Key Fobs

Here are some FAQ you may have:

Can I Program a New Audi Key Fob Myself?

While it's possible to program a new key fob yourself, the process can be complex and requires specialized equipment. It's recommended to have a professional handle the programming.

How Much Does It Cost To Replace an Audi Key Fob?

The cost of replacing an Audi key fob can vary depending on your vehicle model, year, and the source of the replacement. Dealerships typically charge the most, while online retailers and independent locksmiths may offer more affordable options. On average, expect to pay between $200 and $500 for a replacement key fob.

What Should I Do if My Audi Key Fob Is Not Detected?

If your Audi isn't detecting your key fob, first check the battery and replace it if necessary. If the issue persists, see that the key fob is within range of your vehicle and that there are no obstructions interfering with the signal. If the problem continues, you may need to have the key fob reprogrammed or replaced.
