Lost My Key Fob for 2018 Nissan Altima? How to Program a New One

If you've misplaced or lost your key fob for your 2018 Nissan Altima, don't panic! This guide will walk you through the steps to program a new key fob. This process is relatively straightforward and doesn't require any special tools or advanced skills. Follow these steps, and you'll be back to your normal driving routine in no time.

Steps to Program a New Key Fob

The first thing you should do is locate your vehicle's manual, which is usually found in the glove compartment. It will have detailed instructions on the programming process. Follow these steps carefully:

Locate the Fuse Box: Find the fuse box, which is typically located under the dashboard on the driver's side. Refer to your vehicle's manual to find the exact location and size of your fuse box.

Unlock the Vehicle: Unlock the driver's door using the existing key fob if you have one. If not, you will need to enter the vehicle and locate the license plate or front license plate area. Look for the small insert that has the model number and VIN under it.

Start the Vehicle: After unlocking the door, start the engine. It will help your keyless entry system get into programming mode.

Check the Correct Battery Insertion: Ensure that the correct battery, usually 7.5V to 20V, is inserted into the back of the new key fob. The battery size should be specified in your manual.

Insert the Key Fob: Position the new key fob near the driver's side window in the driver's side door jamb area.

Program the FOB: Press and hold the unlock button on the new key fob until the lock and unlock backlight blinks three times. This is the sign that the new key fob has been successfully programmed.

Final Steps: Turn off the engine and remove the key fob from the driver's side. Put the battery back into the key fob, and you're all set!

Alternative Methods: Seeking Professional Services

While programming a new key fob yourself is a viable and cost-effective solution, it might not be the most convenient option for everyone. If you're not comfortable with the process, many car dealers and repair shops offer key fob programming services at a nominal fee. This way, you can ensure that the process is done correctly and efficiently.
