How to Fix repair broken car key That isn't Working
If your key fob doesn't work then you can fix it by following just a few steps. The first step is to be sure that it's not the backup remote.
If remote car key repair near me can lock and unlock the doors of your car, it is likely that the primary remote isn't functioning. The majority of car remote key malfunctions are caused by battery or circuitry problems.
Battery
The battery in the key fob may be worn out over time. It is fairly easy to change out the battery, however it is essential to make sure that you choose the correct type and you can consult your owner's manual, or contact the dealer for the manufacturer to determine the type of battery you require. It is also crucial to check the battery compartment, since dead batteries can leak toxic chemicals that could damage the remote. If changing the battery doesn't fix the problem there could be other issues that require professional attention. If buttons are broken or stuck, for example it might be necessary to remove the remote and rebuild each component. You could also try reprogramming the vehicle to recognize the new remote.
Buttons
Due to frequent use, key fobs can wear out and become dirty. It is not unusual for buttons to stop working, or to require a long press to get them working. This can be very frustrating especially if you're away from home and you need to start your car. Even malfunctioning or worn-out buttons can be fixed with a bit of time and tools you already have at home.
First, ensure that the batteries are up correctly and that the indentation on the back of the button is filled. Then, carefully open up the remote and examine the circuit board. Check for evidence of rust, or other signs the buttons are damaged or worn. For instance the paint that conducts electricity could be missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that has become worn out or where conductive paint is missing. Do not rub too vigorously, as this could erode the conductive paint and prevent 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 in place can restore the button's functionality in the event that this is the case. The same method 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 functioning or require a long press to function, it is likely that the graphite disks on the back of the button are deteriorating and need to be replaced. This can be done by rubbing a pencil over 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 firm press It could be that the circuit board is damaged. It is possible to fix the issue by cleaning and re-soldering the fob but you should also have an extra in case it doesn't work.
Circuitry
Whether or not the keys fob buttons are functioning the circuit board that is inside your remote may be dirty. This problem can be resolved through a thorough examination. The most common causes for dirty circuit boards are water and damaged cases. A damaged case can let water and other debris into the circuit board, which can cause it to short out. Water can also damage pins and connectors that are small on the board, which are known as via's.
If you are handy enough to open your key fob, and you don't mind making some mess, we can remove the buttons from their sockets and put in new ones. It's also worth looking at the battery terminal connections. If they're loose, the buttons might not function or get stuck in their down position. Soldering terminals and buttons back to their proper positions is usually enough to restore a non-working fob back to working.
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 into them or when a door handle for a car or lawnmowers is pushed over them. Most of the time non-remote transponder chip malfunctions could be attributed to a blown fuse.
If you're able to open up a sealed non-remote key fob and are willing to put up with the mess, you can remove the circuit board and test the fuse using a multimeter for proper diode function. If you're unsure about doing this, go to your local hardware store or Oreilly's, and they will usually have an RFID frequency tester that can tell you whether the key fob is sending a signal.
Programming
Key fobs aren't indestructible and are susceptible to damage through a variety of causes. They can break their connection with the receiver in your vehicle because of shocks or a low battery, which calls for changing the program. A professional auto locksmith or a dealer in the main can reprogram your keyfob and get it functioning again. If resetting or repairing the keyfob is not working, you may need to replace it.
