As your trusted auto repair experts at keyfobprog.com, we’ve compiled a helpful guide based on common queries and solutions for VW key fob programming.
~~~~~~~~~~~ Changing the Key FOB Battery ~~~~~~~~~~~~~~~~~~~~~~~~~The first and simplest step for many key fob issues is battery replacement. For the 2010 VW CC key fob, you’ll typically need a CR2032 battery. If your key fob’s red LED indicator fails to light up when you press the buttons, a battery change is likely needed. Refer to online video tutorials for a visual guide on safely opening your fob and replacing the battery.
~~~~~~~~~~~~~~~~ The VW security system for Immobilsor 4 (IMMO 4) systems as found on Golf Mk5, Passat B5 onwards, etc) supply two key fobs that come part coded from the factory. When you go to the dealer with all your details, it's so the dealer can be sure you are the legal owner of that particular vehicle. The parts guy just orders the key from your chassis number, the order is sent to Germany and they part code a blank immobilsor chip to your chassis security details held in the German database. They also cut a physical key, known as the valet key, and attach it to the fob. The fob can take up to five days to arrive at the dealer in the UK. You then take your car into the dealership, its hooked up to their diagnostic machine and then the pairing of the key you ordered can begin. The techie logs into the car, then starts a key coding process. Techie enters their personal login details and the machine does the rest: it matches the part-coded key to the details that are stored on the database and then codes it to the vehicle system. There is no way independents or mobile security companies can code the key to the car's new or old keys.

Volkswagen’s security system, Immobilizer 4 (IMMO 4), commonly found in models like the 2010 VW CC, Golf Mk5, and Passat B6, utilizes key fobs that are pre-coded at the factory. When ordering a new key through a dealership, verification of ownership is crucial. The dealership orders the key based on your vehicle’s chassis number. This request is sent to Germany where a blank immobilizer chip is coded with your car’s unique security details from a central database. A physical valet key is also cut and attached to the fob.
The key fob delivery to the dealership can take several days. Once it arrives, you’ll need to bring your 2010 VW CC to the dealership for the final programming. Technicians use diagnostic equipment to pair the new key to your vehicle. This process involves logging into the car’s system and initiating a key coding sequence. The machine then automatically matches the part-coded key with the stored database details and codes it to your car’s specific system.
While dealerships typically handle this process, some independent services claim to offer key programming. However, for guaranteed compatibility and security, especially with the 2010 VW CC’s IMMO 4 system, dealership programming is often recommended.
If You Have One Good Key (not tried here!) ~~~~~~~~~~~~~~~~~~~~~Reprogramming with an Existing Working Key
If you have one working key for your 2010 VW CC and need to reprogram another fob (that has been previously paired with your car), a DIY method might be possible. This procedure is often mentioned for Passat models and could potentially work for the CC.
- Prepare the Driver’s Door: Locate the manual key slot cover on your driver’s side door handle. At the bottom of the cover, you’ll find a slot. Insert the valet key from your working fob into this slot. Pry downwards to remove the cover, revealing the keyhole.
- Ignition with Working Fob: Insert your working key fob into the ignition and turn it to the “on” position (just before starting the engine).
- Lock Door Manually: Using the manual key, lock the driver’s door from the outside.
- Program New Fob: Press any button on the key fob you are trying to program twice.
The system should now recognize and store the code from the new fob. Unlock the door with your manual key, remove the working fob from the ignition, and test the newly programmed fob. It’s important to note that this method is generally believed to only work for fobs that have been previously paired with your specific vehicle and will not work for fobs from other cars.
If you've Used the Wrong Fob
~~~~~~~~~~~~~~~~~~~~~~~~~ I own two '06 Passats. Inserted wrong fob into ignition to start it. Got error code and fob could not be removed. Called dealer and they said car would have to be towed to them. Checked the internet for help: 1) step on brake pedal. 2) depress automatic shifter knob on "T" handle twice. 3) when click is heard-remove fob... Broken Key to two Fresh Keys ~~~~~~~~~~~~~~~~~~~~~~~~~Dealing with an Incorrect Key Fob
Accidentally inserting the wrong key fob into your 2010 VW CC ignition can sometimes lead to issues where the fob gets stuck and an error message appears. If this happens, dealerships might advise towing the vehicle. However, there’s a reported trick that may help:
- Brake Pedal: Press and hold the brake pedal.
- Shifter Knob: Depress the automatic shifter knob on the “T” handle twice.
- Remove Fob: Listen for a click sound, and then attempt to remove the key fob.
This sequence has been reported to release a stuck key fob, potentially saving you a tow to the dealership.
B6 Partial RE-train using VCDS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ After a prolonged absence of battery cell voltage, the IMMO functions of a key may still work, it'll still start the engine. But you find you can't gain access to your car -- the locking or unlocking don't work -- even though the little red LED in the fob lights up after changing the battery (see above)
To re-train an IMMO-working keyfob to security system: VCDS -> Ch46 (central convenience) -> 10 (adaptation) Channel 0: value 0, Save (rests all remotes) Channel 1: value 2, Save Press Unlock on each remote for more than one second consecutively. My car did not show any signs of acknowledgement like Ross-Tech said it might. Close controller, done. Check operation of each remote for vehicle lock, unlock, and boot. And for vehicle start.VCDS Re-training for Remote Functions
In situations where your 2010 VW CC key fob’s immobilizer is still functioning (allowing you to start the engine) after a battery change, but the remote locking/unlocking features are not working, a VCDS (Vag-Com Diagnostic System) re-train might be necessary. This procedure is more advanced and requires a VCDS tool.
Steps for VCDS Re-train:
- Connect VCDS: Connect your VCDS tool to your VW CC’s diagnostic port.
- Central Convenience Module: Navigate to “Ch46 (central convenience)” within the VCDS software.
- Adaptation: Go to “10 (adaptation)”.
- Reset Remotes (Channel 0): In Channel 0, set the value to “0” and click “Save”. This resets all remote key pairings.
- Set Number of Remotes (Channel 1): In Channel 1, enter the number of keys you want to program (e.g., “2” for two keys) and click “Save”.
- Program Each Remote: Press the “Unlock” button on each key fob for more than one second consecutively. The car may not give any acknowledgment signal during this step.
- Close Controller: Close the controller function in VCDS.
- Test: Test the locking, unlocking, and trunk release functions of each key fob, as well as the vehicle start.
Using VCDS provides a more in-depth method to manage your 2010 Vw Cc Key Fob Programming, particularly for remote functions.
Conclusion
Programming a 2010 VW CC key fob can range from simple battery replacement to more complex procedures like dealer programming or VCDS re-training. For basic issues like battery changes or attempting to re-sync an existing key, DIY methods might suffice. However, for new keys or persistent problems, especially concerning the immobilizer system, professional dealership service or a qualified locksmith with VCDS expertise is recommended to ensure proper and secure key fob programming for your 2010 Volkswagen CC. Always prioritize security and consult your VW owner’s manual or a professional for specific guidance related to your vehicle.
