Although new cars have car fobs, now and again, you should use the conventional way to open the auto entryways so you can see if the locks work properly.
This sounds minor, yet, it works!
Many people just use their auto car fob to begin their auto, and forget to use the key but when the battery of the car fob expires they use the key and break there key because the key was never used and became brittle. Use a spare key replacement or a duplicate.
