Magnetic keys They are less common and are used in some models. Mercury and Yamaha The premium segment: There is a magnet inside the plastic case that activates the sensor in the ignition lock, which is harder to forge, but they are sensitive to strong magnetic fields (such as near powerful speakers or electric motors). Important: Magnetic keys cannot be stored next to credit cards or hard drives, which can demagnetize both the key and the storage media.
The most modern motors (for example, Yamaha F300 V6 or Mercury Verado) equipped chip-keyThey work on the principle of car immobilizers: a chip inside the key sends a unique code to the engine control unit. Without the right code, the engine will not start even if you mechanically turn the key. These systems protect against theft, but create problems when lost - a duplicate can only be made from an official dealer with the presentation of documents for the engine.
How do you know what key your motor has? Notice the following:

⚠️ Attention: All alternative methods of starting can cause a malfunction of the electronic systems of the motor. After using such methods, be sure to contact the service for diagnostics.
