Lost Your Only Motorcycle Key? What to Do Next

Quick answerIf you lost the only key to your motorcycle, a new one can almost always be made, but the route depends on whether your bike uses a plain metal key, a chipped transponder key, or a keyless fob. Gather photo ID, your registration or title, and the VIN, then call a motorcycle locksmith or your dealer. Hold off on a tow until you know whether the key can be made where the bike sits.

Are you sure it is gone?

Spend ten minutes on the obvious places before paying for a new key. Keys left in the seat lock, gas cap, top case or helmet lock are a classic. Check jacket and riding pant pockets, the tank bag, the ground where you parked, and the counter of the last place you stopped. If the key went missing along with something that shows where you live or park, such as a wallet or garage remote, treat it as possibly stolen and plan to change the locks, not just add a key.

What kind of key does your bike use?

The key type sets the price and who can help. Older and many entry-level bikes use a plain metal key, which a locksmith can cut from the key code or from one of the bike's locks. Many newer street bikes add a transponder chip in the key head that the immobilizer must recognize, so the new key also has to be programmed. Do not assume a late-model bike has one, though: plenty of US-market models, including many Kawasakis and Suzukis, still use a plain key. Many touring and premium models use a keyless fob, which often means the dealer is involved.

Clues that you have a chipped key: a thick plastic key head, a security light on the dash that blinks after you switch off, or an immobilizer section in the owner's manual. Our immobilizer guide lists the system names by make.

What to gather before you call

California law requires a locksmith to record your ID and the bike's details before originating a key, so expect these questions. If your registration is locked under the seat, say so when you call. Our proof of ownership guide explains how that is handled.

Photo ID, such as a driver's license or state ID card
Registration or title in your name, or purchase paperwork if you just bought the bike
The VIN, found on the frame at the steering head and on your registration
Year, make and model
Any key code tag, code card, master key or security PIN that came with the bike
Where the bike is parked: garage, parking lot or roadside

Locksmith, dealer, or both?

A mobile motorcycle locksmith comes to the bike, which saves a tow when every key is gone. For plain metal keys and many transponder systems, the key can be cut and programmed on the spot. Some systems, especially factory smart fobs and certain European immobilizers, need the dealer's own software or replacement parts. Ask either one for a total price that covers cutting, programming and travel before you agree, and check whether your insurance or roadside plan includes locksmith service.

On a typical locksmith visit, we check your ID and paperwork, identify the lock and key system, work out the cuts from the key code or one of the bike's locks, cut the key, program it if the bike has a chip, and test it in every lock. You sign a work order. If your bike turns out to need dealer-only parts, you should hear that before any work starts.

After you have a key again

Get at least two working keys made in the same visit. The second costs far less now than another all-keys-lost job later. If the old key could be in someone else's hands, ask about erasing it from the immobilizer memory where the system allows, or rekeying the ignition and locks on a bike without a chip. Photograph the new key code tag and store it somewhere other than the bike.

Quick questions

Can I ride the bike to a shop without a key?

No. Without a working key, or a working fob or PIN on keyless models, the bike will not start and the steering may stay locked. It has to be towed unless the key is made where the bike sits, which is the main reason riders call a mobile locksmith first.

Will my old key still work if I find it later?

Usually, yes, unless the old key was erased from the immobilizer or the locks were rekeyed during the replacement. If you find it and it still works, keep it at home as your spare.

What if the ignition was damaged in a theft attempt?

The ignition usually has to be repaired or replaced first, and the new keys are then made to match it. A locksmith can tell you which is needed after seeing the damage.
