Toyota details that change the job
The most useful details are year, model, trim if known, ignition style, and whether you have any working key. Push-button-start vehicles and keyed-ignition vehicles are usually different conversations.
When a spare saves trouble
If you have one working Toyota key, adding a spare is usually easier than handling an all-keys-lost situation later. A cracked shell, weak buttons, or intermittent starting are good reasons to ask before the key fully fails.
