Blue key Two Button

The Blue Key with Two Buttons, identified by Maserati Part Number 980001801, is more than just a simple key; it’s a sophisticated electronic device that serves as your primary interface with your Maserati 4200 GT’s security and access systems. This distinctive blue key fob combines the traditional mechanical key blade with modern remote control functionality, embodying the blend of classic design and contemporary technology found in your Italian grand tourer.

At its core, this key performs several vital functions:

• Remote Entry and Security: The two integrated buttons allow for convenient remote locking and unlocking of all vehicle doors. Pressing the lock button secures the vehicle and arms the alarm system, providing peace of mind. The unlock button disarms the alarm and grants access.
• Immobilizer Functionality: Crucially, inside the key fob is a small transponder chip. When the key is inserted into the ignition barrel, this chip communicates wirelessly with the vehicle’s immobilizer system. Only if the unique code from the transponder matches the vehicle’s pre-programmed data will the Engine Control Unit (ECU) allow the engine to start. This passive anti-theft feature is a significant deterrent against unauthorized vehicle use.
• Mechanical Access: The physical key blade, which must be cut to match your vehicle’s locks, provides traditional mechanical access to the doors and ignition in case of remote battery failure or electronic issues.

Given its constant use and exposure to daily wear, key fobs can experience various issues. Common problems include wear or damage to the buttons, a drained internal battery (affecting remote functions), or even damage to the transponder chip or remote circuit board from drops or moisture exposure. When purchasing a new key, it’s critical to understand that it typically arrives un-programmed.

Important Note on Programming: For a new Maserati 4200 key (Part Number 980001801) to function correctly, both its remote entry features and its immobilizer transponder must be programmed to your specific vehicle. This process usually requires specialized diagnostic equipment and software, typically available at an authorized Maserati dealership or a highly qualified automotive locksmith. Without proper programming, the key will not unlock the doors remotely, nor will it allow the engine to start due to the active immobilizer system.

Replacing a lost, damaged, or non-functional key ensures full access and security for your Maserati 4200 GT, maintaining the convenience and sophisticated protection designed into your vehicle.
