What You’ll Need
Before we get started, make sure you have the following items:
- A blank transponder key suitable for your Fiat Punto
- A working key that is already coded to your car
- An OBD2 scanner or a similar tool
Step 1: Retrieve the Key Code
Begin by locating and recording your car’s key code. It’s typically found in your car’s documentation or on a metal tag attached to the keys when you purchased the vehicle. If you can’t find it, you may need to contact your Fiat dealership for assistance.
Step 2: Access the Immobilizer System
Plug your OBD2 scanner into the car’s OBD2 port, usually located under the dashboard. Power it on and follow the instructions specific to your scanner model to access the immobilizer system. This system is responsible for authorizing your car’s keys.
Step 3: Program the New Key
With the immobilizer system accessed, select the option to add or program a new key. Follow the prompts on your scanner’s screen to initiate the programming sequence.
Step 4: Enter the Key Code
When prompted, enter the key code you retrieved in Step 1 using the scanner’s keypad or on-screen keyboard.
Step 5: Program the Key
Insert the working key (coded to your car) into the ignition and turn it to the “On” position without cranking the engine. Wait for the scanner to confirm the presence of the working key.
Step 6: Swap Keys
Remove the working key from the ignition and immediately replace it with the new key (blank transponder key). Again, wait for the scanner to confirm the presence of the new key.
Step 7: Test the New Key
Take out the new key from the ignition and attempt to start the car using the new key only. If everything was done correctly, your Fiat Punto should start up without any issues. Congratulations, you’ve successfully coded your new key!
Coding a Fiat Punto key may seem daunting at first, but with the right tools and our step-by-step guide, it’s definitely doable. Remember to take your time, follow the instructions carefully, and consult your car’s manual or a professional if you encounter any problems. Now, go ahead and enjoy the convenience and peace of mind that comes with having a spare key for your Fiat Punto!
