Mercury Grand Marquis Door Lock

The Door Lock system of Mercury Grand Marquis locks the cabin while allowing the driver to unlock all the doors. In early Grand Marquis sedans, a keyed latch with a simple rod-linked mechanism was applied, so that a rotation of the key or press of the interior knob would block the exterior handle. The later models of Mercury included a power operation as standard, which saw the fitment of an electric actuator to the latch. This operated on a driver door switch or the master panel, which allowed every Door Lock to move at once. By the mid-nineties, Grand Marquis drivers benefited from a keypad keyless entry that was mounted on the door skin, letting a sequence of coded presses cycle each Door Lock without a key. After this came the remote keyless fobs, which send a radio code to a receiver that snaps each Door Lock shut or open with a single button press. Now, many Mercury cars even automatically lock the doors when the drive gear is selected or a certain speed is reached. From one generation to another, the owners of Grand Marquis have gone from twisting a metal key to just hitting a push-button electronic signal. However, every system still uses the same latch-and-striker design that prevents the door from opening until the Door Lock disengages. This has ensured the safety of Mercury motorists from one trip to the next.
