Keyless Entry Transmitter Removal, Installation, and Test

NOTE:
If the doors do not lock or unlock with the transmitter, check the LED on the transmitter by pressing the lock or unlock button. If the LED does not come on, replace the transmitter battery.
If the doors unlock or lock with the transmitter, but the LED on the transmitter does not come on, the LED is faulty; replace the transmitter.
If any door is open, you cannot lock the doors with the transmitter.
If you unlocked the doors with the transmitter, but do not open any of the doors within 30 seconds, the doors relock automatically.
The doors will only lock or unlock with the transmitter if the ignition key is inserted in the ignition key cylinder.

Without HDS

1. Transmitter - Test
1.
Open the keyless transmitter and check for water damage.
If you find any water damage, replace the transmitter and register the new transmitter.
If there is no water damage, go to step 2.
2.
Replace the transmitter battery (A) with a new one (CR1620), and try to lock and unlock the doors with the transmitter by pressing the lock or unlock button at least 10 times:
If the doors lock and unlock, the transmitter is OK.
If the transmitter does not work after replacing the transmitter battery, verify that the correction battery was installed and the polarity is correct.
If the doors do not lock and unlock, go to step 3.
3.
Reprogram and register the transmitter, then try to lock and unlock the doors.
If the doors lock and unlock, the transmitter is OK.
If the doors do not lock and unlock, substitute a known-good transmitter, register it and recheck. If still not operating, replace the immobilizer-keyless control unit.

NOTE: The transmitter does not need to be programmed to the vehicle for this test.
If DIFFERENT KEYLESS ENTRY TRANSMITTER CODE WAS RECEIVED is indicated, replace the transmitter and, do the transmitter registration.
If KEYLESS ENTRY TRANSMITTER CODE WAS NOT RECEIVED is indicated, the immobilizer-keyless control unit is faulty, replace it and do the transmitter registration.
NOTE: The transmitter is combined with the immobilizer transponder, so when the transponder is registered by the HDS, the transmitter programming is completed automatically.
