Program The Key Fob

Programming the key fob of your Nissan Altima is a straightforward process that you can do yourself without needing a trip to the dealer.

Press Lock And Unlock Buttons

Start by holding your key fob close to the vehicle. Press the lockbutton and then the unlockbutton on the fob repeatedly, about five times in total.

Wait For Confirmation Signals

After pressing the buttons, watch and listen carefully for confirmation signals from your Nissan Altima. The car will usually flash its hazard lights or beep its horn to indicate it has accepted the key fob.

If the doors don’t lock or unlock, try standing closer to your vehicle. Sometimes, distance affects the signal strength. Also, confirm the battery in your key fob is fresh—old batteries often cause weak signals.

Start The Engine

Now, test the push start feature using your key fob. With your foot on the brake, press the start button on your Altima. The engine should turn on without needing the physical key inserted.

If the engine doesn’t start, verify that your key fob is inside the car and near the push start button. You might also want to check if the key fob battery is strong enough to send the start signal. Troubleshooting this step early can prevent getting stranded later.
