Can a lost motorcycle key be duplicated?
2 Answers
Car keys can be duplicated. The 4S dealership can query the anti-theft password for key configuration from their database based on the vehicle owner's driving license and ID documents. After obtaining this password, the dealership requires the key blade code provided by the owner to cut a new metal key. The basic components of a remote key consist of the following two points: Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., containing an identification code storage circuit and amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency uses radio waves, sending a signal each time the transmission switch is pressed. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the vehicle's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation, where it is compared with the demodulator's identification code.
I've also experienced the frustration of losing my motorcycle key. That time, I parked by the roadside to buy something, and when I turned back, the key was gone. Getting a replacement key is definitely possible, but it depends on the bike type: If it's a traditional mechanical key, find a reliable locksmith, bring your vehicle registration and ID, and they can duplicate a new key on the spot using a key blank. It usually costs between tens to a little over a hundred yuan and takes about half an hour. However, for newer motorcycles with electronic anti-theft chips, you'll need to visit an authorized dealer. They use professional equipment to match the chip signal to prevent accidental starts. The cost can run into several hundred yuan, and you might have to wait an extra day. Don't worry about security—it's best to lock the bike or temporarily cut the power to prevent accidental riding. For daily convenience, I recommend keeping two keys in separate places—it saves a lot of hassle.
