If the door lock of an old door in a rental apartment is not functional, you can try a few things to make it work. First, try lubricating the lock with a silicone-based lubricant to see if that helps it turn more smoothly. If that doesn't work, you may need to tighten or adjust the screws and hardware on the door to ensure that the lock is properly aligned. If these steps don't work, it's best to contact the landlord or property manager to have a professional locksmith come and repair or replace the lock. **

However, if you frequently have passengers or need easy access to the back seats, a four-door car may be more suitable. **
