My smart key is not working. i opened the door with the key part located inside the fob. is there a way to start the car with this key part? i do not see a key hole

The key blade is to open drivers door and glove box only, you did not specifie what model and year of car you have. on most smart key Nissans there should be a port to put the fob in if fob battery is dead

Check for one of the door-open switches to be misadjusted. If the door ajar lamp is lit, the remote locking system will not work. Also check that a second key-fob is not inside the car. The smart locking system will not allow you to accidentally lock the key fob inside the car and will cycle the lock back to the unlocked position immediately if the fob is sensed by the inside-the-car sensor(s).

Key fob is the Smart Key with 3 buttons and no external key for 9-3 from 2003 on.

It does have a blade-type key inside to use to open door in case of remote - central locking system not working.

May be keyfob needs reprogramming.

Keyfob remote reprogramming is not very difficult but on some cases it can be done by dealer service tools.

If the remote s faulty then key fob will not get programmed.

Insert the key in ignition. Turn the key to on position, and cycle the key three times off-on-off-on-off-on. Then with the key fob remote select your remote and then try to operate the vehicle with remote.

These are just the basic procedure, but sometimes it will not help.

On that case dealer is the only option.

Inside the key fob are contacts that get dirty, both the electric side and the push button side, carefully clean them both.

can you manually unlock the lock and open the door?? Is it more than one door or just one specific door? If its just one door, yourcactuator inside the door may be bad or you have a wire issue. If its all the doors, more than likely you blew a fuse or a relay(id say fuse)

i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.

To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.

It looks like you have the "Smart Key" (a small rectangular box) that does not look like a traditional key.
What you also have is a dead battery inside the Smart Key.
Look closely at the box; there is a little button on the side. Press it. This will release a small hidden key. After you remove the small key, use a small flat blade screwdriver to pry the case of the box open at the slot provided. Take the unit to a store that sells miniature batteries, and have it replaced. You will NOT have to reprogram it after the battery is changed. The life span of the miniature batteries is roughly 20 months, less if exposed to RFI, like sitting on a TV, a monitor, or other electrical device. The Smart key TRANSMITS all of the time, even when you do not press the buttons. This is why the battery only lasts 18-20 months. Let me know if this fixes your issue..
