Key Identification and Usage
The lock cylinder keyway is designed so that other model keys will not enter a current model lock cylinder. A single key is used for all locks on the vehicle.
The key identification is obtained from the four-character key code stamped on the knockout portion of the key head. Knock the plugs out of the key head after code numbers have been recorded. The code list, available to owners of key cutting equipment from equipment suppliers, determines the lock combinations from the code numbers.
Lock Cylinder Tumbler Operation
All lock tumblers are shaped alike with the exception of the notched position on one side. As the key is inserted into the lock cylinder, the tumblers are lowered to the correct height so that notches on each tumbler are at the same level. When the notches on all six tumblers line up, two small springs push the side bar into the notches, allowing the cylinder to turn in the cylinder bore. Five types of tumblers are used in making the lock combinations, and each is coded and stamped with a number between 1 and 5.
Scheme 1
Scheme 2
| CAUTION | To help avoid personal injury, always use jack stands when you are working on or under any vehicle that is supported only by a jack. |
| CAUTION | To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed. |
Note. When you are jacking or lifting a vehicle at the frame side rails or other prescribed lift points, be certain that the lift pads do not contact the catalytic converter, the brake pipes or the fuel lines. If such contact occurs, vehicle damage or unsatisfactory vehicle performance may result.
Before beginning any lifting procedure, be sure the vehicle is on a clean, hard, level surface. Be sure all the lifting equipment meets weight standards and is in good working order. Be sure all the vehicle loads are equally distributed and secure. If the vehicle is only being supported at the frame side rails, make sure the lifting equipment does not put too much stress on or weaken the frame side rails (1).
If using any other hoisting methods than those called out, take special care not to damage the fuel tanks, the exhaust system or the underbody.
Scheme 3
| IMPORTANT | The front hoist pads must not contact the rocker panels, the front fenders, the floor pan, or the stone guard moldings. Remove the jacking covers from the rocker panels if necessary. |
Position the frame contact front hoist pads as follows
- Under the front frame rail reinforcement.
- The long sides of the pads, if applicable parallel to the frame rails.
Scheme 4
| IMPORTANT | The rear hoist pads must not contact the rocker panels, the rear fenders, the floor pan, or the stone guard moldings. Remove the jacking covers from the rocker panels if necessary. |
Position the frame contact rear hoist pads as follows
- Under the rear frame rail at the rear axle cradle mount flange.
