Motorcycle & Scooter Keys: reading the quote
Locksmith · Vaughan, Ontario

It starts the same way and adds one step. The broken piece is drawn out with tools made to grip it rather than push it deeper, and the ignition is then checked to see whether the break was a one-off or a sign the lock itself needs attention. A new key is generally cut from the two pieces or by decoding the lock, since a weakened copy could break again in the same spot.
Bringing multiple locks onto one key
Bringing the seat, fuel cap or a storage lock onto the ignition's key is extra work per lock rekeyed, separate from cutting the key itself, and is priced as its own line.
Time spent decoding a lock
Decoding a lock with no key at all, reading every wafer individually, takes longer than copying from an existing key, and that additional time is part of what the quote reflects.
Condition of the existing lock
A clean, well-maintained lock accepts a new key with little extra work. One affected by corrosion or grit may need cleaning or light service before a key can be tested reliably against it.
