After grocery shopping and walking our shopping cart to the car, I remote(key fob) started the car(Altima in sig) from the store exit. It started fine and I could see the lights flash. As I got closer to the car, I remote popped the trunk and it opened so I could load the groceries. Once loaded and shopping cart put in the parking lot cart corral, I remote unlocked my doors for my wife & I to get in running car. NOTHING! The door didn't unlock. So I did it again from the key fob and again, NOTHING!
I did however use the outer door handle buttons to enter the car and get in. All is well and I pressed the brake pedal & push button start to finalize my entry and then drove off and went home. OK? Are you with me so far?
One we got home and unloaded our groceries into the house(being about 5:30 pm), I locked up the car for the night with the key fob. NOTHING! It didn't lock the car. However I could walk up to the car, key fob in hand, and press the buttons on the door handles and all was well/locked up for the night.
The next morning, knowing my issue from the night before and using my key fob, I tried to unlock my car. NOTHING!
None of my key fob buttons worked including the RED emergency button. However, my extra set that my wife keeps, worked just fine.
I could still get in my car(carrying my key fob) and start the engine. As long as I kept the key fob with me, all was well except that none of the fob buttons worked.
Yesterday I got into my car and went to press the start button and got the dash banner stating NO KEY DETECTED. Well, I know that I have to hold the fob to the start button to gain communication. I did so and got the communication "BEEP" and proceeded to start the engine.
Now once again, my key fob buttons all work and everything is well and back to normal. However, I did try this procedure(holding the fob to the start button) when my fob buttons WERE NOT working but it didn't gain communication. Apparently, the key fob battery has to be low enough for the NO KEY DETECTED banner in the dash to appear, in order to gain communication.
I did remove the fob battery last week when this first happened and tested it(3.05v) and it was fine. What I needed to do was, keep the battery out of the key fob - go into the car - and show the fob to the start button to regain communication. Live & Learn!
