What You'll Learn
Identify the correct battery type
To identify the correct battery type for your Golf key, you must first determine the model of your Volkswagen and the year it was manufactured.
If your Volkswagen key fob resembles a simple Volkswagen car key, you likely need a CR1632 battery. On the other hand, if your Volkswagen model is from 1999 or newer, your key fob may resemble a small pod with buttons on one side and a retractable emergency key. In this case, you will most likely need a CR2032 battery.
It is important to note that not all Volkswagen batteries are the same, and you should always check the type of your old battery and replace it with the same size. The CR2032 battery, for instance, is circular and resembles a small disc.
Once you have identified the correct battery type, you can proceed to replace the battery in your Golf key.

Open the key fob
To open the key fob, start by removing the emergency key. Hold the button on your Volkswagen key fob until the emergency key pops out. If your VW key fob doesn't have an emergency key, skip this step.
Now, grasp the fob firmly in your hand or attach it to a small metal key ring that you can hold on your index finger. This will make it easier to handle the fob as you pry it open.
Next, locate the seam that connects the lid and the base of the fob. Use your fingernail or a flat-head screwdriver to gently create a small gap between the lid and the base. Be careful not to scratch the fob's surface.
Once you have created a small gap, you can use the flat-head screwdriver to gently pry the two halves of the fob apart. Insert the screwdriver into the gap and gently apply force to separate the lid and the base.
Your key fob is now open, and you can proceed to remove the old battery and insert a new one, making sure to match the battery polarity (+/-).

Remove the old battery
To remove the old battery from your Golf key fob, start by opening the key fob. If your Golf key fob has a retractable emergency key, press the metal button to flip open the key. If not, hold the button on your key fob until the emergency key pops out.
Once the key fob is open, locate the battery panel. On some models, the battery panel is right beneath the Volkswagen logo. Use a small flat-blade screwdriver or another thin, blunt tool to pry out the battery panel. Insert the tool into the slot next to the battery and apply gentle force to lift the panel out. Be careful not to damage the plastic casing or any other components.
With the battery panel removed, you can now access the old battery. Use your screwdriver or tool to gently pry the old battery out of its slot. Take care not to touch or damage any other electronic components inside the key fob. Set the old battery aside, making sure to dispose of it properly and recycle it if possible.
Before inserting the new battery, take a moment to clean the metal contacts inside the key fob. Use a soft, dry cloth to gently wipe away any dust or residue. This step will help ensure a good connection between the new battery and the contacts.

Insert the new battery
To insert the new battery, place it in the slot with the positive side facing downward. The positive side is indicated by a + symbol. Ensure the new battery is snapped into place securely.
If your VW is an older model, you may need a CR1632 battery. Most new models made after 1999 use a fob that looks like a small pod with buttons on one side and a retractable emergency key. For these models, you will most likely need a CR2032 battery. These are circular batteries that look like small discs.
If you are unsure about the type of battery your key fob requires, check the old battery and replace it with a new one of the same size. These little batteries are known for not being good quality, so if your key fob still doesn't work after inserting a new battery, try another one.
Once the new battery is in place, close the remote case tightly to hold everything in place.

Test the new battery
Once you've inserted the new battery, it's important to test it to ensure it's working properly. Here are some detailed steps to help you test the new battery in your Golf key fob:
- Close the key fob tightly: After inserting the new battery, make sure to snap the battery panel back into place securely. This ensures that the battery is held firmly in position and establishes a good connection with the contacts.
- Test the locking and unlocking functions: Try locking and unlocking your car using the key fob. Press the lock and unlock buttons and observe if the car responds as expected. This is a basic functionality test to ensure the new battery is working.
- Check the remote start function: If your Golf key fob has a remote start feature, test it by trying to start your vehicle remotely. Press the remote start button and listen for the engine to turn over. If the vehicle starts, it indicates that the new battery is functioning correctly.
- Verify the key fob range: Move away from your vehicle and test the key fob at different distances. Observe whether the key fob can lock and unlock the car from a distance. This test helps you determine if the new battery has restored the key fob's range.
- Compare with a known working key fob: If possible, compare the performance of your key fob with that of another known working Golf key fob. This can help you identify any potential issues with the new battery or the key fob itself.
- Seek professional assistance if needed: In case your Golf key fob still doesn't work after replacing the battery, consider seeking professional assistance. Sometimes, the issue may lie with the key fob itself or other electrical components. A professional can diagnose and resolve any underlying issues correctly.
By following these steps, you can thoroughly test the new battery in your Golf key fob and ensure that it's functioning as intended. Remember to pay attention to any unusual behaviour or inconsistencies during the testing process, as it may indicate the need for further troubleshooting or professional intervention.
