If the backup remote is able to lock and unlock your car key and repair door, then there's a likely issue with the primary remote. Most problems with car remote keys are caused by circuitry or battery problems.

Battery

It is not uncommon to find a battery on the key fob for cars to degrade. It is simple to replace batteries. However it is crucial that you choose the right type. You can check your owner's guide or contact the manufacturer to determine the right type. It is recommended to examine the battery compartment with care because dead batteries can leak caustic chemicals that can harm the remote. If changing the batteries does not solve the problem, it may be that there are other issues that require attention by a professional. For instance, if the buttons seem to be stuck or damaged it could be necessary to disassemble the remote and rework its parts. It is also possible to reprogramme the vehicle to recognize the new remote.

Buttons

Through repeated use, key fobs may become worn and dirty. It is not unusual for buttons to cease functioning, or require a hard press to get them working. This can be frustrating, especially when you are away from your home and need to start your car.

First, make sure that the batteries are correctly inserted and that the indentation on the back of the button has been filled. Then, carefully open up the remote and inspect the circuit board. Look for signs of corrosion or other indications that the buttons are worn out or damaged, like missing paint that is conductive. Then, using a Q-tip dipped in alcohol to gently clean any membrane contacts that have damaged or where conductive paint is missing. Avoid rubbing too hard, as this can erode the conductive paint and stop the button firing when the button is pressed.

Also, make sure to inspect the battery connector's terminals to ensure a loose solder connection. If this is the case, soldering them back in place could restore functionality to the button. The same method can be used to restore function to any other loose connections within the fob.

If any of the rubber buttons on the front of the keyfob aren't working or need to be pressing very hard the graphite disks at the back of the button could have worn out and need to replaced. This can usually be done by rubbing a pencil on the disks. This should bring the button back to its original state.

If none of this is useful or if the button doesn't respond to a hard push It could be that the circuit board has become damaged. It is possible to fix this by a quick clean and replacing the solder, but it is best to have an extra fob available in the event this method doesn't work for you.

It's also worth checking the connections between the battery terminals. They can become extremely dirty and if they're loose the buttons might not work or may even remain in their down position. Soldering terminals and buttons back to their original positions is often enough to bring a non-working fob to working.

Non-Remote Transponder Chips

The non-remote chips that are sealed are more durable than their remote fobs. However, they are susceptible to breaking if a hole is drilled into them or when a door handle for a car key remote repair or lawnmowers is pushed over them. Failures of the fuse are typically to blame for non-remote chip failures.

If you're not confident opening the key fob, you can take the circuit board off and use a multimeter to verify that the diode is operating correctly. If you're not confident doing this, head to your local hardware store or Oreilly's, and they'll usually have a RFID frequency tester that can determine if the key fob is sending signals.

Programming
