Do you have to rekey the ignition switch?

Yes, rekeying the ignition switch may be necessary if you want to use a different key for your vehicle, especially after losing keys or if there's a security concern. This process involves changing the internal mechanism of the ignition switch to match a new key. It's typically done by a locksmith or a dealership. However, if you still have the original key and it functions properly, rekeying is not required.
