One variation may include a product comprising a stud assembly including a stud comprising a first metal and an insulator attached to the stud. Another variation may include a method comprising providing a stud assembly and an appliqu&#xe9;, wherein stud assembly comprises a stud comprising a first metal and an insulator attached to the stud, the appliqu&#xe9; comprising a second metal; attaching the appliqu&#xe9; to the stud assembly so that the insulator isolates the first metal from the second metal of the appliqu&#xe9;.

Insulated stud for attaching applique to metal body vehicle and methods of making and using the same

A door having a latch mechanism is provided. The door also includes a bracket, and a pawl having a first aperture. The pawl is rotatably attached to the bracket and is operatively connected to the latch. The door additionally includes a key-cylinder adapted to selectively lock and unlock the latch by rotating the pawl, and a shield having a second aperture. Furthermore, the door includes a component connected to the key-cylinder. The component is aligned with and extends through the first and second apertures without contact with the pawl or with the shield, and is configured to not impede the rotation of the pawl by the key-cylinder when the component is aligned with the first and second apertures. The component is also configured to detach the pawl from the bracket and limit the key-cylinder extraction, when the key-cylinder is forcibly manipulated thereby causing the component to contact the shield.

Anti-theft device for an access door

A vehicle door having an electronic unlatch system and a method of operation. The door includes an electronic key cylinder mounted to the door and includes a slot that receives a key; a switch engaging the key cylinder to detect when a key has been turned in the cylinder; and a door latch mounted to the door to selectively unlatch the door, with the door latch receiving a signal from the switch to unlatch the door. The door also includes a backup power supply mounted in the door and supplying electrical power to the door latch and switch, with the backup power supply receiving power from a vehicle electrical system to recharge the backup power supply.
