If you find yourself stranded with a dead Volkswagen key fob, don’t panic! Replacing the battery is a simple and straightforward process that can be accomplished in just a few minutes. With the right tools and a little bit of know-how, you can have your key fob up and running again in no time.
The first step is to gather the necessary tools. You will need a small Phillips head screwdriver, a new CR2032 battery, and a soft cloth. Once you have your tools, you can begin the process of replacing the battery. Start by removing the key blade from the fob. This is typically done by pressing a small button on the side of the fob and pulling the blade out. Once the blade is removed, you will see a small screw on the back of the fob. Use the screwdriver to remove the screw and then carefully open the fob.
Once the fob is open, you will see the battery. Use the soft cloth to gently pry the battery out of its holder. Be careful not to damage the battery or the fob. Once the old battery is removed, insert the new battery into the holder. Make sure that the positive (+) side of the battery is facing up. Once the new battery is in place, close the fob and replace the screw. Finally, reinsert the key blade and you’re all set! Your Volkswagen key fob should now be working properly.
Locate the Key Battery Compartment
The location of the key battery compartment can vary depending on the specific model of Volkswagen you have. However, in general, it is typically found in one of the following places:
- Inside the key fob itself, usually accessible by pressing a small button or lever to release the battery compartment.
- Within the key blade, which is the metal part of the key that inserts into the ignition. The battery compartment may be concealed by a small cover or screw.
- In some models, the key battery compartment may be located inside the vehicle’s dashboard or center console. Refer to your vehicle’s owner’s manual for specific instructions.
To locate the key battery compartment accurately, it is recommended to consult your vehicle’s owner’s manual or refer to online resources specific to your Volkswagen model.
Identify the type of key you have. Volkswagen has two main types of keys: traditional metal keys and keyless entry fobs. Traditional metal keys do not require a battery, while keyless entry fobs do.
If you have a traditional metal key, skip to Step 3. If you have a keyless entry fob, proceed to Step 2.
Locate the key fob. The key fob is usually a small, plastic device that contains the keyless entry transmitter and the battery. It may be attached to your keychain or stored in your vehicle.
Locate the battery compartment. The battery compartment is usually located on the back or bottom of the key fob. It may be covered by a small door or flap.
Use a small screwdriver or your fingernail to pry open the battery compartment. Be careful not to damage the compartment or the battery.
Remove the old battery. The old battery will be a small, coin-shaped battery. It may be held in place by a small clip or spring.
Insert the new battery. The positive (+) side of the battery should face up.
Close the battery compartment. Make sure the compartment is closed securely so that the battery does not fall out.
Test the key fob. Press the buttons on the key fob to make sure that it is working properly. If the key fob is not working, check the battery to make sure that it is installed correctly.
Remove the Old Battery
1. Locate the small switch on the side of the key fob. It is usually located at the bottom or top of the fob, depending on the model.
2. Slide the switch to the unlock position. The key blade will pop out slightly.
3. Gently pull the key blade all the way out of the fob.
4. Flip the key fob over and locate the battery cover. It is usually located on the back of the fob, near the top.
5. Use a small flathead screwdriver or a key to pry open the battery cover.
6. Remove the old battery from the fob. It is usually held in place by a metal clip.
| Volkswagen Key Fob Battery Sizes |
|---|
| CR2025 |
| CR2032 |
| CR1632 |
7. Inspect the battery contacts and clean them with a cotton swab dipped in rubbing alcohol if they are corroded.
Insert the New Battery Correctly
Inserting the new battery correctly is crucial to ensure the key functions properly. Follow these precise steps to ensure a secure battery replacement:
- Align the Battery: Carefully align the positive (+) and negative (-) terminals of the new battery with the corresponding markings on the key. The positive terminal is typically marked with a “plus” sign (+), while the negative terminal is unmarked.
- Insert the Battery: Gently slide the new battery into the key, making sure it’s fully seated and fits snugly. Do not force the battery into the key.
- Check Polarity: After inserting the battery, press any button on the key. If the key does not respond, remove the battery and check if the polarity is correct. Ensure that the positive terminal (+ side) of the battery is facing outward towards the metal contacts in the key.
Pro Tip: To extend the life of the key battery, avoid exposing the key to extreme temperatures or moisture. Additionally, switch to a keyless entry system or key fob to reduce wear and tear on the physical key.
| Battery Type | Shape | Voltage |
|---|---|---|
| CR2032 | Coin-shaped | 3V |
| CR2025 | Coin-shaped | 3V |
| CR1620 | Button-shaped | 3V |
Test the Key Fob
Before diving into the process of changing the key fob battery, it’s essential to verify that the battery is indeed the source of your issues. To do this, perform these quick tests:
Check if the key fob is working at a closer distance
Move closer to your car while pressing the buttons on the key fob. If the car responds when you’re within a shorter range, it may indicate a weak battery.
Try a spare key
If you have a spare key fob, try using that to unlock and start your car. If the spare key works flawlessly, it further confirms the battery issue with your primary key fob.
Observe the key fob’s LED light
Some Volkswagen key fobs have an LED light that indicates when a button is pressed. If the light is dim or doesn’t illuminate at all, it’s a strong indication of a low battery.
Identify any signs of physical damage
Inspect the key fob for any cracks, dents, or water damage. If you find any physical damage, it may have compromised the battery or other components, necessitating professional attention.
Replace the Battery Cover
Once you have successfully removed the key blade, it’s time to replace the battery cover. Here are the detailed steps you need to follow:
5. Replace the Battery Cover
5.1 Insert the Key Blade
Carefully insert the key blade back into its designated slot on the top of the key fob. Ensure that it aligns properly and slides in smoothly.
5.2 Align the Battery Cover
Take the battery cover and align it with the corresponding slot on the back of the key fob. Make sure that the edges of the cover match up with the grooves on the key fob.
5.3 Secure the Battery Cover
Apply gentle pressure to snap the battery cover into place. You should hear a clicking sound indicating that the cover is securely locked.
5.4 Double-Check Fit
Once the battery cover is in position, try to wiggle or twist it slightly. If it doesn’t move or feels loose, it means the cover is correctly secured.
5.5 Test the Key
To ensure that the battery replacement was successful, press any button on the key fob. If the buttons work properly and the key fob functions as expected, you have successfully replaced the battery.
| Step | Action |
|---|---|
| 5.1 | Insert the key blade |
| 5.2 | Align the battery cover |
| 5.3 | Secure the battery cover |
| 5.4 | Double-check fit |
| 5.5 | Test the key |
Ensure Proper Key Functioning
To ensure the Volkswagen key functions properly, it’s essential to regularly replace the battery. A discharged battery can cause intermittent or complete failure of the key’s functions, including locking/unlocking doors, starting the vehicle, and activating the panic alarm.
6. Replace the Battery and Reassemble the Key
Once the key is disassembled and the old battery is removed, it’s time to replace it with a new one. Here’s a detailed guide:
- Insert the New Battery: Carefully slide the new battery into the designated compartment inside the key fob. Ensure the positive (+) terminal of the battery faces upwards.
- Secure the Battery: Use a small screwdriver or tweezers to gently push down the metal contact point onto the negative (-) terminal of the battery.
- Reassemble the Key Fob: Align the two halves of the key fob and press them together firmly until they snap closed. Make sure all components are securely in place.
- Test the Key: Insert the key into the vehicle’s ignition or use it to unlock and lock doors. Verify that all functions are operating smoothly.
