If buttons are broken or stuck for instance it could be necessary to take the remote apart and rework each component. You can also try reprogramming the vehicle to recognize the new remote.
Buttons
Through frequent use, key fobs may become worn and dirty. It is not unusual for buttons to stop functioning, or require a long push to make them work. This can be frustrating, especially when you are away from home and have to start your car. Even malfunctioning or worn-out buttons can be fixed with a bit of time and materials you already have at home.
First, make sure the batteries are properly charged and that the indentation on the back of the button is filled. Open the remote carefully and examine the circuit board. Examine for signs of rust or other indications that the buttons have been worn or damaged. For example there could be conductive paint missing. Use a Q-tip dipped into alcohol to gently clean any membrane contact that has worn out or where conductive painting is missing. Don't rub too hard as this can damage the conductive paint and prevent the button from firing when it is pressed.
Check the battery connector terminals for loose solder connections. Soldering them back to their original position will allow the button to function again If this is the case. The same method can be used to restore function to any loose connections in the fob.
If any of the rubber buttons on the front of the keyfob isn't working or need to be pressed extremely hard the graphite disks at the back of the button may have worn out and will need to replaced. You can do this by rubbing a pen over the disks. This should bring the button to life.

Non-Remote Transponder Chips
The non-remote chips sealed in a sealed case are more durable than remote fobs. However, they are susceptible to cracking if a hole is drilled in them, or if a car door handle or lawnmowers plows over them. Most of the time non-remote transponder chip malfunctions could be attributed to a blown fuse.

A professional auto locksmith or a dealer in the main can reprogram the key fob and get it back working again. If, in the unlikely event that resetting or repairing your key fob doesn't work, it could be time to replace it entirely.
