How to Fix a Key Fob That isn't Working

If your key fob isn't functioning, a few easy steps can fix it. The first step is to make sure that it's not the backup remote.

If your backup remote cannot lock key repair near me and unlock the doors of your vehicle, it is likely that the main remote is not working. The most frequent causes of key problems with your car remote are issues with the circuitry or battery.

Battery

It is not unusual to find a battery on a car mobile key fob repair lock repair near me (published on husum-donaldson-2.federatedjournals.com) key fob to degrade. It is fairly easy to change out the battery, however it is essential to ensure that you choose the correct type; you can look in your owner's manual, or contact the manufacturer's dealer to find out what kind of battery you require. It is recommended to examine the battery compartment carefully since dead batteries may release caustic chemicals that could damage the remote. If replacing the batteries doesn't solve the issue it could be because there are other issues that require attention from a professional. If the buttons are stuck or broken, for example, it may be necessary disassemble the remote and rework each component. You can also try reprogramming the vehicle to recognize the new remote.

Buttons

Through frequent use, key fobs may get dirty and worn. This is not unusual, but it can cause buttons to stop functioning or require a long press to work. This can be very frustrating, especially when you are away from your home and you need to start your car. Even broken or damaged buttons are often fixable with a bit of time and tools you already have at home.

First, ensure that the batteries are properly charged and that the indentation on the back of the button is filled. Then, carefully open up the remote and inspect the circuit board. Check for signs of corrosion or other indications that buttons are worn out or damaged, like missing paint that is conductive. Then, using the Q-tip, dipped in alcohol, gently clean any membrane contacts that have damaged or where conductive paint is missing. Don't rub too hard as this can damage the conductive paint and stop the button from firing when it is pressed.

Examine the battery connector's terminals for loose solder connections. Soldering them back to their original position will restore the button's functionality if this is the situation. The same method can be used to restore function to any other loose connections within the fob.

If any of the rubber buttons located at the front of the keyfob aren't working or need to be pressed extremely hard the graphite disks on the back of the button could have worn out and need to replaced. This can be done by rubbing a pencil across the disks, which will bring the button back to life.

If none of these solutions work or you cannot get the button to respond when pressed hard, it could be that the circuitry is failing. This can be fixed by a quick clean, and replacing the solder, but it is recommended to have an additional fob on hand in the event that this method does not work for you.

Circuitry

The circuit board inside the remote control could be dirty, regardless of whether the buttons on the key fob function or not. The issue can be solved by a thorough inspection. Broken and damaged cases are the most common causes of dirty boards. A damaged case can allow water and other debris to pass through and short circuit the electronics. Water can also get through pins and vias, which are tiny connectors found on the board.

If you're handy enough to remove your key car repair fob and don't mind some mess, we can remove the solder from the buttons and then solder new ones in their place. It's also worth examining the battery terminal connections. If they're loose, the buttons may not function or get stuck in their down position. Soldering the terminals, and putting the button back in their place is generally all it takes to restore a non-working key fob to working order.

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 if a car door handle or lawnmowers plows over them. The majority of non-remote transponder chip failures could be attributed to blowing fuses.

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

Programming

Key fobs aren't indestructible and can be damaged by a variety of factors. They can lose their pairing to the car's receiver due to shock or low battery, which calls for the reprogramming. A professional auto locksmith or a main dealer can reprogram your key fob to get it functioning again. If resetting or fixing your key fob fails, you may need to replace it.
