How to Program Your Universal Car Remote: A Step-by-Step Guide (Model ASTU15 and Similar)

Lost your car remote or need to program a new universal car remote like the ASTU15? Paying dealership prices for a simple programming procedure can be frustrating. Luckily, for many vehicles, including some Nissan and Infiniti models, you can program your keyless entry remote yourself, often for free. This guide will walk you through the process, providing instructions based on common methods and models, and help you understand how these steps can apply to programming universal remotes like the ASTU15.

While specific instructions can vary slightly depending on your car’s make, model, and year, as well as the specific universal remote you are using, the underlying principles are often similar. Let’s explore two common methods used for Nissan and Infiniti vehicles, which can provide a foundation for understanding how to program your universal car remote.

Method 1: Ignition Key Cycling (For QX4, 1997-2001 Q45, I30, 1999-up G20)

This method involves using your ignition key to enter programming mode. Here’s how to do it:

1. Ensure all doors are closed and locked. This is a crucial first step for initiating the programming sequence.
2. Insert and remove the key from the ignition cylinder rapidly. Do this more than six times within 10 seconds. It’s important to fully withdraw the key each time. If done correctly, the hazard warning lamps will flash, indicating you’ve entered programming mode.
3. Insert the key into the ignition and turn it to the “AAC” (Accessory) position. At this point, the system is ready to learn the new remote ID code. Any previously programmed remote codes are usually erased at this stage for security.
4. Press any button on your new remote controller once. After pressing a button, the hazard warning lamps should flash again, confirming that the remote’s signal has been received and programmed.
5. For additional remotes (optional): If you are programming more than one remote, unlock and then lock the doors again using the power door lock/unlock switch located on the main power window switch.
6. Remove the key from the ignition.
7. Unlock the driver’s side door, open it, and then close it. This completes the programming sequence.

Important Notes for Method 1:

• You can program up to four remote controllers using this method. Attempts to program more will be ignored.
• If you have additional remotes to program, repeat step 5 for each new remote.

Method 2: Trunk and Door Switch Method (For J30, 1994-1996 Q45, 1994-1996 G20)

This method utilizes the trunk switch in combination with ignition key cycling.

1. Close and lock all doors. Start by ensuring all doors of your vehicle are securely closed and locked.
2. Unlock the trunk using the door switch. Locate the trunk release switch, usually found on the driver’s side door panel, and unlock the trunk.
3. Insert and remove the key from the ignition cylinder six times within 10 seconds. Similar to Method 1, fully remove the key each time. This action puts the system into programming mode.
4. Manually unlock and lock the driver’s side door. Use the manual lock switch on the driver’s side door to unlock and then lock the door.
5. Push any button on the new remote controller once. Pressing a button on the remote transmits its ID code to the vehicle.
6. For additional remotes (optional): To program more remotes, repeat steps 4 and 5.
7. Complete the process. The programming is now complete.

Important Notes for Method 2:

• Like Method 1, this method also allows you to program up to four remote controllers.
• Repeat step 6 for each additional remote you need to program.

Programming Universal Car Remotes Like ASTU15

While the above methods are specific to certain Nissan and Infiniti models, the general approach can be similar for programming universal car remotes like the ASTU15. Universal remotes are designed to work with a wide range of vehicles. Here’s how the process usually works:

1. Identify your vehicle’s programming method. Check your vehicle’s owner’s manual or search online for “[your car make model year] remote programming instructions”. This will help you determine if your car uses a method similar to the Nissan/Infiniti examples above, or if it requires a different procedure.
2. Enter programming mode on your vehicle. This often involves key cycling, pressing specific pedals in a sequence, or using the ignition switch in a particular way. Refer to your vehicle-specific instructions.
3. Activate the programming function on your ASTU15 universal remote. Universal remotes typically have a “program” button or a sequence of button presses to initiate learning mode. Consult the ASTU15 remote’s manual for precise instructions.
4. Synchronize the remote with your vehicle. Once both your car and the universal remote are in programming mode, you may need to press a button on the remote to transmit its signal and synchronize it with your car’s receiver. This might involve pressing the lock or unlock button on the ASTU15 remote.
5. Test the remote. After completing the steps, test all buttons on your ASTU15 remote to ensure they are functioning correctly with your vehicle’s locks, trunk release, and other remote-controlled features.

Troubleshooting Tips:

• Hazard lights not flashing: If the hazard lights don’t flash when you cycle the key, you may not be performing the steps quickly enough or correctly. Try again, ensuring you fully remove the key each time and complete the cycles within the specified timeframe.
• Remote not responding: Double-check the battery in your universal remote. Ensure you are pressing the buttons correctly and within range of the vehicle. If programming fails repeatedly, there might be an issue with the remote itself or your vehicle’s receiver.
• Consult manuals: Always refer to your vehicle’s owner’s manual and the manual that came with your universal car remote model ASTU15 for the most accurate and specific instructions.

Programming your universal car remote can save you money and provide the convenience of keyless entry. By understanding the general processes and following the specific instructions for your vehicle and remote, you can often complete this task yourself successfully. Remember to always double-check your vehicle and remote manuals for the most accurate procedures.
