If your backup remote is unable to lock and unlock the doors of your car, then it is most likely that the primary remote isn't working. The most frequent causes of key malfunctions for car remotes are issues with the circuitry or battery.
Battery
The battery in a key fob can be worn out over time. It is simple to replace the battery. However, it is important that you choose the right type. You can consult your owner's guide or contact the manufacturer to find out the right type.

Buttons
Through repeated use, key fobs can wear out and become dirty. This is not uncommon however, it can cause buttons to cease working or require a very long press to function. This can be a hassle especially when you're away from your home and need to start your car. Fortunately, even worn out or damaged buttons can be fixed with a bit of time and a few materials you might already have in the house.
First, verify that the batteries have been correctly placed and that the indentation at the back of the button has been filled. Then, carefully open the remote and look at the circuit board. Examine for signs of rust or other signs that the buttons are worn out or damaged, like missing conductive paint. Use the Q-tip, dipped in alcohol to gently clean any membrane contacts that have worn or where conductive paint is missing. Be careful not to rub too hard, since this could cause damage to the conductive paint and stop the button from firing when it is it is pressed.
Examine the battery connector's terminals for loose solder connections. Soldering them back in place will allow the button to function again if this is the situation. The same method can be used to restore function to any other loose connections inside the fob.
In the end, if any of the rubber buttons on the front of the key fob aren't working or require a very long press to function, it is likely that the graphite disks on the back of the button are wearing out and require replacement. This is usually done by rubbing a pencil across the disks, which will bring the button back to life.
If none of this is helpful, or if the button does not respond to a hard press, then it may be that the circuit board itself has become damaged. It is possible to fix this by cleaning and re-soldering the button but you should also have a spare in case it doesn't work.
Circuitry
The circuit board inside the remote control could be dirty regardless of whether the buttons on the key fob function or not. A thorough examination is often enough to resolve this issue. Broken and damaged cases are the most frequent causes of dirty boards. A broken case allows water and other debris to get in and short out the electronics.

It's also worth checking the battery terminal connections. They can get very dirty and if they're loose the buttons may not work or may even remain in their down position. Soldering the terminals, and putting the button back into place is typically all that's needed to return the key fob that is not working to functioning condition.
Non-Remote Transponder Chips
The non-remote chips sealed in a sealed case are more durable than remote fobs, however they can be cracked if a hole is drilled in them, or in the event that a door handle of a car or lawnmower runs over them. The majority of non-remote transponder chip malfunctions can be blamed on blowing fuses.
If you're able to remove the sealed key fob and are able to bear the mess, you can take off the circuit board and examine the fuse with a multimeter for proper diode function. If you're not comfortable with this, go to your local Oreilly or hardware store and test their RF frequency tester. This will tell you whether the key fob sends an RF signal.
Programming
Key fobs are subject to a lot of abuse and aren't impervious to damage. They may lose their connection with the receiver in your vehicle due to shocks or low battery, which calls for changing the program. A professional auto locksmith or dealer can reprogram your key fob to get it back up and running. If resetting or replacing your keyfob does not work it may be necessary to replace it.
