Programming a new key for your 2020 Alfa Romeo might seem like a straightforward task, especially if you’ve purchased a key fob online. However, as many owners discover, it’s not as simple as following generic instructions. Let’s delve into the complexities of programming an Alfa Romeo key and what you need to do it correctly.
The process for programming Alfa Romeo keys, particularly for models like your 2020, is more intricate than many DIY guides suggest. Unlike some vehicles where a simple sequence of steps can program a new key, Alfa Romeo utilizes a more secure system. Attempting to program a new key without the right tools and knowledge can lead to frustration and failure, as you may have already experienced.
To successfully program a key for your 2020 Alfa Romeo, you need to understand that it typically involves programming all keys simultaneously, not just the new one. This means you’ll need both your original key and the new key fob you intend to use. Furthermore, this procedure requires specific diagnostic tools and security credentials.
One of the essential tools for this process is MultiECUScan (MES). This software, popular among Alfa Romeo enthusiasts and technicians, allows for in-depth diagnostics and programming, including key programming. MES outlines the correct procedure for FOBIK (Frequency Operated Button Integrated Key) type keys used in many Alfa Romeo models.
According to MES instructions, programming keys involves the following crucial steps and considerations:
-
All Keys Must Be Programmed Together: When you initiate the key programming procedure, you must have all the keys you intend to use for the vehicle present and ready to be programmed. Any keys not programmed during this session will be disabled.
-
Security Code Requirement: A critical element for programming Alfa Romeo keys is the electronic key code specific to your vehicle. This security code is not readily available and is typically obtained from an official Alfa Romeo service or dealer. Attempting to guess or bypass this code is not advisable, as entering an incorrect code multiple times (even three times) can lead to a temporary lockout of the Body Computer for about 30 minutes.
-
MES Procedure Steps: The procedure within MES generally follows these steps:
- Initiate the Procedure: Start the key programming procedure within the MES software.
- Prepare FOBIK 1: The system will prompt you to prepare the first key (FOBIK 1). You then briefly press the “UNLOCK” button on the key fob once and wait for the system to recognize it. MES will confirm if the key recognition is successful.
- Prepare Subsequent FOBIKs: The system will then prompt you to insert and program FOBIK 2, FOBIK 3, and so on, for all the keys you want to program (up to 8 keys are supported). Repeat the “UNLOCK” button press for each key as prompted.
- Finalize and Store: Once all keys have been recognized, MES will store the data for all recognized keys into the Radio Frequency Hub module (RFH). It will display a status update, giving you a final chance to abort if needed.
- Test Keys: After the procedure is complete, disconnect the OBD cable, exit the vehicle, and test all programmed keys to ensure they function correctly for locking, unlocking, and starting the car.

Important Warnings and Notes from MES:
- Caution is Advised: MES explicitly warns users not to attempt this procedure without proper understanding, as incorrect execution can disable your car keys.
- Have All Keys Ready: The warning to “MAKE SURE YOU HAVE ALL KEYS” is emphasized because any keys not programmed in the same session will become unusable.
- Vehicle OFF: The procedure should be performed with the car turned OFF. Do not press the START button to turn the car ON or start the engine during the process.
- Simulation Mode: MES offers a simulation mode, which can be helpful to walk through the procedure and understand the steps without actually making changes.
If obtaining the security code from a dealer proves difficult or costly, there are alternative methods, although they often involve additional expense. For instance, tools like the Autel key programmer can sometimes retrieve the security key code. However, these professional-grade tools can be quite expensive, making them less practical for occasional use.
In conclusion, programming a key for your 2020 Alfa Romeo is not a simple DIY task. It requires specialized tools like MultiECUScan, the correct security code for your vehicle, and a careful approach to programming all your keys simultaneously. If you are not comfortable with these steps or obtaining the necessary tools and codes, it is recommended to seek assistance from a qualified Alfa Romeo technician or dealership to ensure the process is carried out correctly and without issues. Attempting to bypass security measures or using incorrect procedures can lead to complications and potentially immobilize your vehicle.
