How do I renew my BC Services Card for seniors?

Could you please elaborate on the process of renewing a BC Services Card for seniors? Is there a specific form that needs to be filled out? Are there any documents that are required to be submitted along with the renewal application? Additionally, is there a deadline for renewing the card, and if so, what happens if it's not renewed on time? Lastly, is the renewal process done online or is it necessary to visit a physical location? I'm looking for a comprehensive guide on how to renew my BC Services Card as a senior. Thank you.
