How to Program Your Universal Car Remote Model ASTU15: A Step-by-Step Guide

Lost your car remote or need to program a new universal car remote model ASTU15? Paying dealership prices to program a simple key fob can be frustrating. Luckily, for many Nissan and Infiniti models, and potentially your universal car remote model ASTU15, you can program it yourself at home, absolutely free. This guide will provide you with easy-to-follow, step-by-step directions to reprogram your key fob, saving you time and money. While the exact steps may vary slightly depending on your specific car model and remote, these instructions are based on the common procedures for Nissan and Infiniti vehicles, offering a helpful starting point for programming remotes, including potentially universal models like ASTU15.

Reprogramming Nissan and Infiniti Key Fobs: Step-by-Step Instructions

The following instructions are designed for various Nissan and Infiniti models. While we aim to cover a broad range, always consult your vehicle’s owner manual for the most accurate and model-specific instructions for your car and remote, especially if you are working with a universal car remote model ASTU15.

For Models: QX4, 1997-2001 Q45, I30, 1999-up G20

These steps are applicable to a range of older Nissan and Infiniti models. If your vehicle falls within these models and years, follow these instructions to reprogram your key fob.

1. Ensure All Doors Are Closed and Locked: Begin by making sure all doors of your Nissan or Infiniti vehicle are completely closed and securely locked. This is a crucial starting point for the programming sequence.

2. Ignition Key Cycling: This step involves quickly inserting and removing your key from the ignition cylinder. Insert and remove the key more than six times within a 10-second timeframe. It’s important to fully withdraw the key from the ignition cylinder each time. Successful completion of this step is usually indicated by the flashing of the hazard warning lamps.

3. Turn Ignition to “AAC” Position: After the hazard lights flash, insert the key back into the ignition cylinder and turn the ignition key switch to the “AAC” (Accessory) position. At this point, the vehicle’s system is ready to accept the new ID code from your remote, and any previously stored ID codes will be erased.

4. Press a Button on the New Remote: Take your new remote controller (or universal car remote model ASTU15 if applicable) and press any button on it once. If the programming is successful, the hazard warning lamps should flash again, confirming that the new remote’s ID code has been entered.

   This image displays a standard car remote control. Pressing a button on the remote is the key action that transmits the programming signal to the vehicle.

5. Additional Remote Programming (Optional): If you have more than one remote to program, you can program up to four remotes. To program additional remotes, release the door lock and then lock it again using the door lock/unlock switch located on the power window main switch. Repeat step 4 for each additional remote.

6. Final Steps: Remove the key from the ignition. Unlock the driver’s side door, open the driver’s side door, and then close the door. This completes the programming sequence.

Important Notes for Multiple Remotes:

• If you need to program more than two additional new remote controllers, repeat step 5 “Additional ID code entry” for each new remote controller.
• Entry of a maximum of four ID codes is allowed. Any attempt to enter more will be ignored by the system.

For Models: J30, 1994-1996 Q45, 1994-1996 G20

For slightly older Nissan and Infiniti models within the specified years, the programming procedure is a bit different. Follow these steps carefully if your vehicle falls into this category.

1. Close and Lock Doors: As with the previous method, start by ensuring all doors are closed and locked securely.
2. Unlock the Trunk via Door Switch: From the door switch, unlock the trunk. This is a specific step for these older models.
3. Ignition Key Cycling (Shorter Cycle): Insert and remove the key from the ignition cylinder six times within 10 seconds. Remember to fully withdraw the key each time. At this point, the system is ready to learn new remote codes, and previous codes are erased.
4. Manually Unlock and Lock Driver’s Door: Manually unlock and then lock the driver’s side door using the manual lock mechanism or switch.
5. Press Button on New Remote: Press any button on your new remote controller (or universal car remote model ASTU15). If you only have one remote, skip step 6.
6. Additional Remote Entry (Repeat Steps): For each additional remote you need to program, repeat steps 4 and 5.
7. Completion: The programming process is now complete.

Important Notes for Older Models:

• If you need to activate more than two additional new remote controllers, repeat step 6 “Additional ID code entry” for each new remote controller.
• Just like the newer models, entry of a maximum of four ID codes is allowed. Attempts to enter more will be ignored.

What About Programming a New Ignition Key with a Chip?

It’s important to note that programming a new ignition key that contains a chip (transponder key) is different from programming a keyless entry remote. Unfortunately, programming these chipped ignition keys yourself is generally not possible. This type of programming typically requires specialized equipment and access to the vehicle’s immobilizer system.

Dealer Programming Required: Programming a new ignition key with a chip usually requires a visit to a qualified dealership. Dealerships have the necessary Infiniti Computer, specialized programs, and security access (passwords) to program these keys correctly.

Save Money by Programming Your Remote at Home

By following these steps, you can potentially save yourself a significant amount of money by programming your key fob or universal car remote model ASTU15 at home, rather than paying for dealership services. Always double-check your vehicle’s owner manual for the most accurate instructions and remember that these steps are a helpful guide for many Nissan and Infiniti owners.
