Battery

It is not uncommon to find a battery on a key fob for cars to degrade. It is easy to replace batteries. However, it is important that you choose the right kind. You can consult your owner's manual or call the manufacturer to inquire about the right type. It is also essential to examine the battery compartment as batteries that are not working properly can release caustic chemicals which can damage the remote. If changing the batteries doesn't solve the issue it could be that there are other issues that require professional attention. If buttons are damaged or stuck for instance, it may be necessary take the remote apart and rework each component. You could also try reprogramming the vehicle to recognize the new key fob.

Buttons

Key fobs may become dirty and worn out from frequent use. It is not uncommon to have buttons stop working, or to require a hefty push to make them work. This can be a huge hassle especially if you're away from home and you need to start your car. Fortunately, even worn-out or malfunctioning buttons can often be fixed with a little time and a few materials you have in the house.

First, check that the batteries are charged correctly and that the indentation on the back of the button is filled. Take the remote apart and inspect the circuit board. Look for signs of rust or other indications that the buttons are damaged or worn. For example there could be conductive paint missing. Utilizing a Q-tip that has been dipped in alcohol, gently clean any membrane contacts that have worn or where conductive paint is missing. Do not rub too vigorously as this can damage the conductive paint and stop the button from firing when you press it.

Also, make sure to inspect the battery connector's terminals to ensure a loose solder connection. Soldering them back into place will allow the button to function again If this is the situation. You can follow the same method to restore functionality to any other loose connection in the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob stop working or require a long press to function it is likely that the graphite disks at the back of the button are wearing down and need to be replaced. This can usually be done by rubbing a pencil on the disks, which will bring the button back to life.

If none of these solutions work, or if you still not be able to get the button respond when pressed hard, it could be that the circuitry is failing. This can sometimes be repaired by a quick clean, and re-soldering, but it is best to have an extra fob in case this method doesn't work for you.

Circuitry

Whether or not the keys fob buttons are functioning, the circuit board inside the remote could be dirty. This problem can be resolved through a thorough examination. The most frequent causes of dirty circuit boards are water and damaged cases. A damaged case can allow water and other debris to enter and short out the electronics. Water can also get through pins and vias, which are the tiny connectors that are found on the board.

If you are handy enough to open your key fob, and aren't afraid of making some mess, we can take the buttons out of their sockets and solder in new ones. It's also worth looking at the battery terminal connections. 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 proper positions is usually enough to bring a non-working fob back to working.

Non-Remote transponder chips

Sealed non-remote transponder chips are more durable than the remote fobs that have them but they can be damaged by a hole that is drilled into them or run over by a lawnmower or car door handle. Most of the time, non-remote transponder chip failures can be blamed on blowing fuses.

If you are not comfortable opening the key fob, remove the circuitboard and utilize a multimeter to determine if the diode is working properly. If you're unsure about doing this, visit your local hardware store or Oreilly's and they usually have a radio frequency tester that can tell you whether the key fob sending a signal.

Programming

Key fobs are not indestructible and are susceptible to damage by a variety of factors. They can break their connection with the receiver in your vehicle due to shocks or low-battery, which requires the reprogramming. A professional auto locksmith or main dealer can reprogram the keyfob to get it functioning again. If resetting or fixing your key fob fails it may be necessary to replace it.
