It sounds like the buttons on your remote are bad, but we should run a CAN scan to see what comes up, you can get a CAN scanner from Amazon for about $30.00.
Here is a video to show you how:
Here is a scanner link:
Door lock control (Lock and unlock), back window control (Back window open) and panic control (Theft alarm and flash) is performed by remote control, without the ignition key inserted in the door key cylinder, using low power electrical waves emitted by a transmitter.
1. Normal Operation
When the lock SW on the transmitter is pressed, all the doors are locked.
When the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressed again within 3 seconds all the doors are unlocked.
2. Auto Lock Function
When the door is not actually opened within 30 seconds after the door has been unlocked by the unlock SW on the transmitter, all the doors are automatically locked. If any of the following conditions are detected, the wireless door lock does not function.
- Any door is opened.
- The ignition key is inserted into the ignition SW.
- When the lock detection SW of all the doors are locked.
3. Wireless Door Lock Stop Function
If any of the following conditions are detected, the wireless door lock does not function.
- When any door is open (Door courtesy SW on)
- The ignition key is inserted into the ignition SW (Unlock warning SW on)
- Ignition SW is on
- Ignition SW is on
4. Buzzer Sound Function
During lock operation, when the body ECU receives a lock signal from the door lock detection SW, the wireless door lock buzzer goes on once. During unlock operation, when the body ECU receives an unlock signal from the door lock detection SW, the wireless door lock buzzer goes on twice.
With any door open, when the body ECU receives a lock signal from the transmitter, the wireless door lock buzzer goes on for approx. 10 seconds. If the door is closed, or ignition SW is on, or if the unlock signal is received from the transmitter while the buzzer is on, the buzzer stops.
5. Visual Confirmation of Lock or Unlock
During lock operation, when the body ECU receives a lock signal from the door lock detection SW, the turn signal light is flashed once. During unlock operation, when the body ECU receives an unlock signal from the door lock detection SW, the turn signal light is flashed twice.
6. Remote Panic Operation
Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once, interior lights light up, and theft alarm and horn sounds and turn signal light, headlights and taillight flash. Then, the panic or the unlock button (Transmitter) is pushed once more, interior lights are turned off, sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.
7. Repeat Function
If the lock detection signal in response to the output signal is not received after the body ECU has output the lock signal, the lock signal is output again.
8. Buzzer Volume Control
The volume of the wireless door lock buzzer can be set among 5 steps by operating the transmitter, when the ignition SW is off, any door open, and the ignition key is not in the ignition key cylinder.
9. Back Window Control
When the ignition SW is off, the ignition key is not inserted into the ignition key cylinder, the back window can be opened by pressing the back window open SW of the transmitter for approximately 0.8 seconds. At that time, the wireless door lock buzzer beeps once.
10. Illuminated Entry Function
When the body ECU detects the unlock state after the unlock operation has been made, it turns on the lights, such as the ignition key cylinder light and interior light for approx. 15 seconds. If all the doors are locked during this operation, lighting is cancelled and the lights immediately fade out.
