Vehicle coverage and appointment preparation
For a faster estimate, send the year, exact model, push-button start status, whether any key still works, your city, and photos of the dashboard and existing key.
The Toyota Sienna may use different key systems across different years. Older models may use a transponder chip key or remote head key, while newer models may use a smart proximity key with push-button start. Before quoting, we confirm the year, trim, ignition type and whether any working key is available.
| Situation | Recommended approach |
|---|---|
| Need a spare key | Make it while one key still works when possible. |
| All keys lost | Verify ownership, decode/cut key and program when supported. |
| Remote not working | Check battery, shell, button condition and programming. |
| Smart key lost | Confirm push-start system and correct proximity key type. |
Many models can be serviced on site, but exact support depends on year, system and available parts.
Call first. Mobile service may avoid towing when the vehicle system is supported.
Text the year, model, photos of the dashboard/ignition and whether it is push-start or turn-key.
