Please choose the correct ending to complete the given sentence: Philosophy and Religion: [header] How to lock your car and why [title] Check the operator's manual. [step] All cars have manual methods of locking and unlocking the doors, but nowadays, the vast majority also have automatic locks. Check the vehicle's instruction manual to determine which locking mechanisms your car has.

Ending1: [substeps] To identify the required mechanisms, the trunk is usually located next to the engine below the rear fender at the bottom corner. Some vehicles now have automatic locks on the trunk as well. Ending2: [substeps] If you don't have a manual, call the police. You may have trouble learning to unlock the car yourself. Ending3: [substeps] If you do not have the operator's manual, check inside the car to look for automatic lock buttons. Cars that do not have internal automatic locks probably don't have external automatic locks, either. Ending4: [substeps] If the manual does not give specific information about how to get in and out of your vehicle, call a repair store or ask a mechanic before attempting to unlock your vehicle. If the manual was lost, but has been stored in someone else's car (such as a vehicle you own), contact your local mechanic.
