The keys are double sided and reversible. The master key and valet key contain transponders that are read by the theft deterrent system when the keys are used in the ignition. The keys have 10 cut positions (1) with 4 different depths (2).

The keys that are furnished with the vehicle are:

The key code can be obtained from the 4-digit number on the key tag that accompanies the original master and valet keys. The 4-digit key code cross references to the cut and tumbler sequence. The keys have 10 key cut positions (1) and 4 key cut depths (2). Key cut positions are numbered 1-10, counting from the head of the key to the tip. The key cut depths are 1-4, cut depth number 1 is the deepest cut. The key transponder (3) in the master and valet key must be programmed to the vehicle. Refer to appropriate service procedure for programing the keys to the vehicle.

1. Cut a blank key to the proper depth and sequence of each of the tumbler positions.
2. Inspect the mechanical operation of the key in the lock cylinders in the doors, the ignition switch, the rear compartment lid and any storage compartments:

With each side of the key pointing up inside the lock, inspect the operation of the lock in both directions.

•	Turn the key both directions in each lock cylinder.

•	Turn the key with each side of the key pointing upward in each lock cylinder.

3. If replacing a master or valet key, program the key transponder to the vehicle.

Each of the four cut depths on the key has corresponding tumblers (sometimes referred to as plates or wafers). The tumbler depth number is stamped on the tumblers for identification. The IP storage compartment lock cylinder also require a retainer tumbler. The retainer tumbler is not moved by the key, its function is to retain the IP storage compartment lock cylinder in the lock assembly.

The ignition lock cylinder uses only seven of the ten cut positions, 3 through 9. The tumbler positions are staggered from side to side, four on one side and three on the other.

1. Hold the cylinder (7) so that the side with four tumbler spring wells is facing up.
2. Insert tumbler springs (5) into the four spring wells.
3. The first tumbler to be loaded will be the 3rd key cut position (the 3rd number in the key code). Install the first tumbler (4) in the slot nearest the front of the lock cylinder, this is the side into which the key would be inserted.
4. Install the three remaining tumblers on this side of the lock cylinder, key cut positions 5, 7 and 9.
5. Snap the tumblers into place with light hand pressure.
6. Check for correct loading of the tumblers (4) by inserting the key into cylinder (7). All of the tumblers should be flush with the lock cylinder.

12. Inspect for correct loading of the tumblers (4) by inserting the key into cylinder (7). All of the tumblers should be flush with the lock cylinder.
13. Lightly lubricate the tumbler (4) surfaces using the provided lubrication.
14. With the key inserted into the housing, align the retaining bar with the groove on the inside diameter of the cylinder housing. This groove extends through to the back of the lock housing (6).
15. Lifting the flat spring and button, install the cylinder (7) into the cylinder housing (6). The retainer bar snaps into place when the cylinder (7) is fully seated.

The door lock cylinder only uses seven of the ten cut positions, 3 through 9. The tumbler positions are staggered from side to side (4 on one side and 3 on the other). The left and right door lock cylinders are identical. The lock pawl determines which side of the vehicle the lock cylinder is on.
