1. Close all the doors and insert the key into the ignition.
2. Turn the key off then on repeatedly until the door locks cycle. End with the key turned on.
3. Press the lock or unlock button on the key fob. If the doors lock (or unlock), the key fob is programmed.

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.

Hey Lisa,
You are going to have to take the car and the key fobs to the dealership .
They will need all of the fobs , as they are all going to need to be reprogramed at once ;
The fob on an 07 Pontiac only can be programed using a diagnostic scan tool .
They will connect the scan tool to the vehicle.
Turn key to on position.
Select 1 body,
then select special functions
then select program key fob,
select the number of key fobs you want programed.
Press and hold the lock and unlock key simultaneously for about 15 seconds until the power locks cycle to confirm the remote is programed.

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 have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
