Drove car 5 days ago no problem. Now I push start button and nothing happens. I but in fob and it slides out still not starting

There's an antenna for the transponder receiver built into the key surround on the 9-5, it could have had a knock or be faulty.

On the 9-5 if the transponder stops working and you get a key not accepted message then you can override it by pushing the unlock button on the key remote with the ignition turned to on and it should let you start the car.

Check and see if the battery is charged. It may be that something electrical was left on and your battery is drained.

Looks like you need it reprogrammed but to do that you'll need a dealer, call a Jeep service dept and ask them what to do.

Nissan been having some problem with key FOB, they don't wont to acknowledge it cause it will turn into a RECALL expensive fix for them.

It may be corrosion; If you hear a louder "click" it may be the contact on the starter solenoid down on the starter. If this is a recent development, this is a likely cause.

it is less likely but still remotely possible the push button itself has corrosion issues, or there is enough debris to insulate the contacts electically.

Does the red light on the remote light up when you push any of the button
if no, replace remote
if yes, then try repograming the remote to the car again.
-Have remotes' ready. if you have two then fob#1 and fob#2 (doesn't matter which one is #1 or #2)
-each step has to be done within 5 sec or it will not work, but don't do it super fast.
1.turn key just to the "on" position (not starting) and push "lock button " on fob#1 once and release
2.turn key off
3.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
4.turn key off
5.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
6turn key off
7.turn key just to the "on" position (not starting) and push "lock button " on fob#1 twice (if you only have one fob, then stop here and go to step 8)and push the "lock button" on fob#2 twice.
8.turn key off and remove key from ignition.
if you did it right, remotes' should work again.
good luck

First thing, does the red light on the remote light up when you push any of the button
if no, then replace battery inside remote
if yes, then try repograming the remote to the car again.
-Have both remote ready. fob#1 and fob#2 (doesn't matter which one is #1 or #2)
-each step has to be done within 5 sec or it will not work, but don't do it super fast.
1.turn key just to the "on" position (not starting) and push "lock button " on fob#1 once and release
2.turn key off
3.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
4.turn key off
5.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
6turn key off
7.turn key just to the "on" position (not starting) and push "lock button " on fob#1 twice (if you only have one fob, then stop here and go to step 7)and push the "lock button" on fob#2 twice.

Sounds like the neutral safety switch is going bad. Next time it does this to you with the engine off and the selector in neutral pop the clutch by pushing it down all the way then letting your foot slide off to the side so it's pops up and then see if you can start it. If this works you need to adjust the clutch and or replace the neutral safety switch on the transmission.

You need to remove the battery cables and clean the connections with a wire battery terminal cleaning tool. Then start the car and check the voltage at the battery with a multimeter. It should be between 13.5-16 volts. Any less and the alternator is defective. If this all checks out and you are 100% sure nothing is on drawing power then the battery more than likely has a dead cell. Remove the battery and take it to your parts store and have it tested. You will probably need a new battery.

I had this same exact problem in a family member's Saturn. If you are opening the door with the key and not using the key FOB to unlock the doors, then the security system will not allow you to start the car. You will notice when this happens that the dome light will blink and you'll hear the relay in the BCM clicking.

In order to stop the security system from doing this: Make sure the car is locked with the key fob by hitting the lock button. Then hit the unlock button on the key fob once and then once again (I do it out of habit). Then open the driver side door, put the key in and it should start no problem.
