A vehicle body contains many openings apart from the vehicle doors. They include engine compartment hoods, hatch and tailgate openings, fuel doors, and battery access covers.

All of these openings have to be secured and may require a remote switch or lever to be activated. In some cases the activation is by cable, others may use electric or vacuum solenoids.
Some rear hatch openings have a hinged window incorporated, so the owner can have easy access without opening the entire door.
Engine compartment hoods may use single or double acting hinges. Their release may be located inside the passenger compartment, under the dash, in the glove compartment or on a doorjamb.

Some manufacturers are no longer fitting an engine compartment release to their vehicles. The hood can only be released by the manufacturers scan tool or by a service key fitted into a secluded opening on the vehicle body (usually behind a manufacturers badge). Before opening the engine hood on these vehicles, check the owner's manual, or the manufacturers manual, as unauthorized access may void any vehicle warranty.
