Before starting the process, make sure you have:
- Your current .cer file (Public Certificate) and .key file (Private Key).

### Renew an expired e.firma
You can renew your e.firma online if it expired less than one year ago, using the[SAT ID](https://satid.sat.gob.mx/),[CERTIFICA](https://portalsat.plataforma.sat.gob.mx/certifica/), and[CertiSAT Web](https://aplicacionesc.mat.sat.gob.mx/certisat/) tools.
Example: If your e.firma expired on October 5, 2025, you can renew it online until October 5, 2026, at 11:59 p.m. If it expired more than a year ago,[you'll need to schedule an appointment to apply for it again in person at an SAT office](https://guia.mifiel.com/efirma-como-tramitar?hsLang=es-mx&__hstc=45788219.05511574b32b71759628b3f867f95714.1784321536825.1784321536825.1784321536825.1&__hssc=45788219.1.1784321536825&__hsfp=d0efb20c80462fcee91bdbff6b085bc1).
