Nissan cars with keyless entry will display key on dashboard display if battery of key runs out. Normally it can be resolved by replacing the battery. See video above.
Emergency Start: There is a way to start the car in case of emergency. If you don't have access to new battery then you can start the car by pressing the button with your key FOB. There is a sensor in your key below Nissan logo which should be kept near the Start-Stop button when pressing it. This should work even if there is no battery in the key. You can give it a try.
does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck
probably sensor for keyless entry,but would not advise u too get this from a junk yard as the sensors are vin specific,will put ur car into anti-theft mode then u will have to replace the body control computer,have a dealer order u a keyless entry sensor vin specific for ur car,these are usually under dash up top middle area its a little black box,will have to remove dash pad or dash to replace.
Step by Step Solution:
1. Check the battery in your Key Fob/Remote, Replace?
2. If after replacing battery and still does not work then may have lost programming, or bad keyless entry module.
3. May need to take to dealer to have programmed or keyless entry module replaced.
Key fobs have to be reprogrammed. something has knocked the coding off. Search the web for procedures to program fobs. It usually entails operating ignition a series of power lock sequences and the like. If that does not work you can take it to the dealer and they can recode it using the data from you cars computer, but that is extremely expensive.
Lock your car with the keyless entry.Push it twice.Then walk over to passenger side and un lock with key.Then put key in ignition and start the car..If that dont work lock the doors again with the keyless entry.Push lock twice and then push the unlock twice..that should start your car,Repost if you have no luck to consider different stratigies.
Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
