2001 Tahoe 4x4 Lt

My keyfob broke so I cannot open my tahoe with key without alarm going off. I have a spare remote to another Truck I had which was the same year and model. I tried programming new keyfob but I cannot get it to work. Am I doing the correct steps?

 

1. Hold unlock button and move key on-off on-off and let go of button.

2. I hear and see doors lock and unlock.

3. I hold together the lock and unlock buttons on keyfob at the same time for about 45sec but no response.

While I am doing these steps my alarm is going off. Any suggestions appreciated.

Almost. First, start the truck with the key, this should disable the alarm. Then follow these steps.

Close all the vehicle doors.

Insert the ignition key into the ignition lock cylinder.

Press and hold the door unlock switch.

While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.

Release the door unlock switch. The doors will lock and unlock to confirm the program mode.

Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.

Repeat the previous step to program up to four transmitters.

Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.

Operate the transmitter functions in order to verify correct system operation.

HTH.

Tried that but still will not program keyfob. Any other suggestions. Alarm was working fine, its just the keyfob that broke. Plastic case broke and a solder joint for battery holder broke. Tried two other spare keyfobs but will not program either.
