Bike keys look simple. Some are. Others carry a chip, and some newer bikes use a keyless fob. Here is how to sort out a lost or broken motorcycle key without trailering the bike to a dealer.

Plain Keys on Older Bikes

Many older bikes and scooters use a plain key. A locksmith can often cut one from the code stamped on the lock or on a small tag that came with the bike, or by reading the lock itself. The ignition, fuel cap and seat or helmet lock may share one key or use several, so tell the tech which locks you need.

Chip Keys on Newer Bikes

Many bikes from the 2000s on, including models from Honda, Yamaha, Kawasaki, Suzuki, BMW, Ducati and Triumph, have an immobilizer. That means a chip key, like a car. Some brands use a red master key to program new keys. If you have the red key, keep it somewhere safe and never ride with it. Losing it can turn a cheap job into a costly one.

Keyless Fobs

Many newer Harley-Davidson models use a hands-free fob instead of a key to start. If the fob dies or is lost, you can usually still start the bike with a personal PIN you set up in the system. Set one now if you have not. If you lose the fob, a Harley dealer is often the easiest path to a new one.

Getting It Done

• Ask the locksmith if they do motorcycles, and your exact make, model and year. Not every car locksmith does.
• Bring ID and the title or registration.
• If the bike is somewhere it cannot sit, a mobile tech saves you a trailer rental.
