With access through the main door, just unscrew the inside faceplate to check out what's happening when the key rotates between lock/unlock. Fix/replace from there.

If it's not unlocking because the cylinder just keeps spinning and you have no other means of entry: might as well drill.

What's your favorite way to figure out an all-keys-lost situation? Lishi, ignition/cylinder pull, vin decode software...?
