Step-by-Step Programming Instructions:

**Note:** The remote keyless entry system comes with 2 transmitters, each having 2 unique vehicle access codes programmed into the wireless door lock ECU.

**Modes of Registration (Programming the Remote):**
There are 4 registration modes:

1. **Add Mode:** Adds a transmitter (remote) without erasing existing transmitter codes. Four transmitter codes can be registered at one time. If the number of registered codes exceeds 4, previously registered codes are erased in order, starting with the first registered code.

2. **Rewrite Mode:** Erases all previously registered transmitter codes and reprograms new transmitters.

3. **Confirmation Mode:** Informs the user of the number of existing transmitter codes already programmed in the system.

4. **Prohibition Mode:** Erases all existing registered transmitter codes and cancels wireless door lock operation. Use this function if the transmitter is lost or stolen.

**Registration of Recognition Code:**

1. To begin programming, remove the key from the ignition switch. Ensure the driver’s door is open and unlocked, and all other doors are closed. Insert the key into the ignition switch and then remove it.

2. Complete the following steps in 40 seconds or less: press the door lock switch (the one that controls all the locks) to the LOCK position, and then within one second, press the door lock switch to the UNLOCK position. Repeat this procedure continuously until the door locks have been locked and unlocked 5 times. Close and then open the driver’s door.

3. Complete the following steps in 40 seconds or less: repeat the procedure in step 2, except for closing and opening the driver’s door. Insert the key into the ignition switch. To enter the desired mode, turn the ignition switch to the ON position and back to the LOCK position (one cycle) within one second, the specified number of times. See the Registration Mode Selection table below. Remove the key from the ignition switch. Registration of the confirmation code is complete after the door locks cycle. Be sure to continue as below.

**Registration Mode Selection:**
“`
Mode| No. Of Ignition Switch Cycles
———————————————-
Add | 1
Rewrite | 2
Confirmation | 3
Prohibition| 5
———————————————-
“`

4. If any mode other than the confirmation mode is selected, go to the next step. If confirmation mode was selected, the door locks will cycle 0-4 times depending on how many transmitter codes are stored in the ECU. For example, two stored codes equal 2 door lock/unlock cycles.

5. Complete the following steps in 40 seconds or less: If add mode, rewrite mode, or prohibition mode is selected, to confirm proper initiation, the door lock will automatically cycle one time for add mode (at the end of step 3), 2 times for rewrite mode, and 5 times for prohibition mode. Press the transmitter LOCK and UNLOCK buttons simultaneously for at least 1.5 seconds, and then within 3 seconds, press any transmitter button for at least one second.

6. If within 3 seconds, the door locks cycle one time, the new transmitter code has been successfully accepted. Go to the next step. If the door locks cycle 2 times, the new transmitter code was not accepted. To program an additional transmitter or to make a second attempt, return to step 5 within 40 seconds.

7. Registration of recognition codes is complete under any of the following conditions:
– Forty seconds have elapsed since the wireless door lock ECU has responded.
– Driver’s door is closed.
– Key is inserted into the ignition key cylinder.
– Four recognition codes are registered at one time.
