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)

hi you can do this but you will have to have a key that does not have a remote/fob on it ( basically just go get one cut cheaply ) then to reprogram keys/key fob's first using the key without fob, turn ignition on ( do not turn over, just to position 2) then lock drivers door with other key ( do not use fob, just the key itself with fob now complete the following within 30 seconds within 5 seconds( of locking the car) press the unlock button on the first key once ( this programs that key as key memory1) the indicators should flash once to indicate signal received wait 5 seconds then press unlock on key fob vehicle should then unlock meaning key fob has been programmed and programming ended open door turn ignition off , and that's it, it should work if you have more than 1 key with fob, do the same as above but instead of pressing unlock once, you do it twice, if third key 3 x if fourth key 4 x etc etc,

I had that happen too and found out that if you hold the unlock button down on your FOB for about 4-5 seconds then it will roll down the front windows. It's actually a feature, not a problem. You may have accidentally mashed something up against the FOB while it was in your pocket and you were within range of the car. That's what I did. Freaked me out the first time I walked out in the driveway and both front windows were down and I know I didn't leave them open.

If it is a 2003 model year vehicle follow this procedure. If it doesn't work, you may have the wrong fob which happens all the time.

Sit in vehicle and close all doors.
COMPLETELY insert and remove ignition key more than six times within 10 seconds.
Hazard lights should flash twice.
Turn ignition to ACC position
Press and hold any button on the new key fob hazard lights will flash twice
For a second key fob using the master lock switch, lock and unlock the doors then hold down any button on the second remote until the hazard lamps flash twice.
Then you are done open the door to exit the programming mode.
If the lamps didn't flash when holding down the key fob make sure you have the right key fob, they are different for each car.
