Battery

It is not uncommon for the battery in the key fob for cars to wear out. It is relatively easy to change out batteries, but it is important to ensure that you select the correct one that you can refer to your owner's manual, or contact the manufacturer's dealer to find out what kind of battery you need. It's also a good idea to inspect the battery compartment with care, as dead batteries sometimes leak harmful chemicals that can harm the remote. If replacing the batteries doesn't solve the problem, it may be that there are other issues that require professional attention. If buttons are damaged or stuck, for example, it may be necessary take the remote apart and rework each component. You can also try reprogramming the vehicle to recognize the new key fob.

Buttons

Through repeated use, key fobs may wear out and become dirty. This is not uncommon however it can cause buttons to cease working or require a very difficult press to get them to work. This can be a hassle particularly when you're away from home and need to turn on your car. Fortunately, even worn-out or broken buttons can usually be fixed with just a bit of time and some of the materials you might already have in the home.

First, make sure that the batteries have been correctly placed and that the indentation at the back of the button is filled. Open the remote carefully and examine the circuit board. Check for signs of rust or other signs the buttons are damaged or worn. For example the paint that conducts electricity could be missing. Utilizing a Q-tip dipped in alcohol, gently clean any membrane contacts that have damaged or have conductive paint missing. Avoid rubbing too hard, since this could cause damage to the conductive paint and stop the button firing when the button is pressed.

Also, be sure to check the battery connector's terminals to ensure a loose solder connection. Soldering them back to their original position will restore the button's functionality If this is the situation. The same procedure can be used to restore functionality to any other loose connections within the fob.


In the end, if any of the buttons made of rubber that are on the front of the key fob stop working or require a very long press to function it is likely that the graphite disks on the back of the button are wearing down and require replacement. This can usually be done by rubbing a pencil across the disks. This should bring the button back to its original state.

If all of this doesn't help or if the button still does not respond to a firm press, then it may be because the circuit board has become damaged. This can sometimes be repaired by a quick clean and re-soldering, but it is ideal to have a spare fob in case this method does not work for you.

Circuitry

They can get very dirty and if they're loose the buttons might not work or even stick in their down position. Soldering the terminals and buttons into place is usually enough to bring a non-working fob to working.

Non-Remote transponder chips

Sealed non-remote transponder chip are more durable than remote fobs that have them however they are still susceptible to being broken by a hole being drilled into them or run over by a lawnmowers blade or car door handle. Fuse failures are usually the cause of non-remote chip failures.

If you're handy enough to remove a sealed non-remote key fob and are willing to put up with the mess, you can easily remove the circuit board and test the fuse using an instrument to verify diode function. If you're not comfortable with this, you can go to your local Oreilly or hardware store and test their RF frequency tester. This will let you know whether the key fob is sending signals.

Programming

Key fobs take a lot of abuse and aren't impervious to damage. They can break their connection with the receiver in your vehicle due to shocks or a low battery, requiring the reprogramming. A professional auto locksmith, or the main dealer can reprogram the keyfob to get it working again. In the event that resetting or repairing your key fob isn't working, it could be time to replace it completely.
