Losing your car key is a frustrating experience, and it happened to me shortly after purchasing my 2000 Vw Gti. Initially, having just one key didn’t seem like a big deal. Famous last words, right? A few weeks later, I found myself frantically searching everywhere for my misplaced key. The sinking feeling of realizing it was truly lost was quickly followed by the dread of potential replacement costs. Modern car keys, especially for vehicles like the 2000 VW GTI, are known to be electronically complex and expensive to replace.
My first instinct, like many, was to turn to Google for answers. Dealerships are the obvious solution, but the thought of towing my 2000 VW GTI and facing potentially high dealership charges was unappealing. I knew modern car keys weren’t simple metal blanks; they’re integrated with the car’s computer system to prevent theft. Programming is required, adding to the complexity and likely cost at a dealership.
Fortunately, online forums provided a more promising direction. I discovered a couple of websites that seemed to offer solutions for DIY key programming. After some research, TuneMyEuro.com emerged as the most helpful option. They stood out because they accepted proof of ownership via email – a copy of the car’s title, registration, and my driver’s license. This allowed them to cut a new key based on my 2000 VW GTI’s VIN number and, crucially, provide the necessary programming tool. This meant I could program the key myself, avoiding the dealership altogether.
What You Need and What It Costs
For a total of $140 (including $5 shipping), I purchased a replacement key and the programming tool. Losing the original key was undoubtedly a costly mistake, but at least I now had a spare and avoided potentially much higher dealership expenses for my 2000 VW GTI.
Understanding Key Programming: Immobilizer vs. Key Fob
It’s important to distinguish between two types of key programming for your 2000 VW GTI: immobilizer programming (for starting the car) and key fob programming (for remote locking/unlocking). This article focuses on immobilizer programming.
When you program the key immobilizer, you’re essentially teaching your 2000 VW GTI to recognize your new key, not the other way around. Each key contains a Radio-Frequency Identification (RFID) chip inside. Every time you insert the key into the ignition of your 2000 VW GTI, the car attempts to read this RFID chip. If the chip isn’t recognized, the immobilizer system prevents the engine from starting.

| Valet Key | Sidewinder Key (Key Fob) |
In my case, I opted for a basic valet key and skipped the key fob (sidewinder key) programming for my 2000 VW GTI. My original key fob was non-functional anyway. Programming the key fob requires additional software, typically VCDS (VAG-COM Diagnostic System). Links for key fob programming information are provided at the end of this guide if you’re interested in that functionality for your 2000 VW GTI.
Step-by-Step Guide to Programming Your 2000 VW GTI Key Immobilizer
Here’s how I successfully programmed the immobilizer for my 2000 VW GTI using the Vagtacho software and cable:
Step 1: Software Installation
Install the Vagtacho software on your laptop. This is usually a simple process of extracting the ZIP file to a folder on your desktop. A laptop is necessary because you’ll need to connect it to your 2000 VW GTI using the programming cable. A desktop PC won’t work for this.
Step 2: Launch the Vagtacho Program
Open the newly created folder and run “vagtacho.exe”. This will launch the Vagtacho programming software.
Step 3: Connect the Vagtacho Cable to Your Laptop
Plug the Vagtacho programming cable into a USB port on your laptop.
On my older Windows XP laptop, drivers were not required. However, depending on your operating system, driver installation might be necessary. I initially tried using a Windows 8 laptop, but it failed to recognize the Vagtacho cable. Windows 7 is also reported to be compatible. You’ll know the connection is partially successful when some of the buttons in the Vagtacho software become active (change from grey to black text).
Step 4: Connect to Your 2000 VW GTI via the OBD-II Port
Locate the OBD-II port in your 2000 VW GTI. It’s typically found under the dashboard on the driver’s side, near the steering wheel. Plug the other end of the Vagtacho cable into this port.
Step 5: Insert New Key and Turn Ignition On
Insert one of your new, unprogrammed keys into the ignition of your 2000 VW GTI and turn the ignition to the “on” position. You should see a warning light on the dashboard, often resembling a key or car symbol. This light indicates that the car doesn’t recognize the inserted key.
Step 6: Select ECU in Vagtacho Software
In the Vagtacho software, use the “Select ECU” dropdown menu. For my 2000 VW GTI, the “VDO Old K-Line…” option worked. If you select the wrong option, you’ll likely encounter an error in the next step. If this happens, simply try a different selection from the dropdown.
Step 7: Connect to the Selected ECU
Click the “Connect Selected ECU” button in the Vagtacho software. You should see text indicating that the software is attempting to connect to your 2000 VW GTI’s ECU (Engine Control Unit).
Step 8: Read the PIN Code
Once connected, press the “Read Pin” button. The software should display a 4-digit PIN code. Write this number down (e.g., “9821”). This PIN is crucial for the next step.
Step 9: Program the New Key
Click “Program New Key”. In the PIN code field, enter “0” followed by the 4-digit PIN you wrote down in the previous step (e.g., “09821”). Enter the number of keys you are programming in the “Number of keys” field. Check the “Erase Old Keys” box if desired (this will prevent old, lost keys from potentially starting the car). Leave the “Channel” option as default and click “OK”.
Step 10: Turn Ignition Off
When prompted by the software, turn the ignition off and remove the key from your 2000 VW GTI.
Step 11: Program Additional Keys (If Applicable)
If you have multiple keys to program, insert the next key into the ignition and turn it to the “on” position. Wait for approximately 5 seconds. Repeat this process for all remaining keys.
Step 12: Test and Start Your 2000 VW GTI!
Disconnect the Vagtacho cable from your 2000 VW GTI. Now, insert one of your newly programmed keys and attempt to start the car. If everything was successful, your 2000 VW GTI should start and continue running! Congratulations!
