Does a 1998 Chrysler sebring key have chip?

No, 1998 Chrysler Sebrings did not have keys with transponder chips (immobilizer systems) as standard equipment. While some higher-end models or optional packages *might* have included them, it wasn't a standard feature for that year and model. Therefore, you should assume your 1998 Chrysler Sebring key does *not* have a chip unless you have specific documentation stating otherwise.
