20 Questions You Should Ask About Remote Key Repair Before You Decide To Purchase It
How to Fix a Key Fob That isn't Working
If your key fob isn't working, a few easy steps can fix it. First, make sure that it's not your backup remote.
If your backup remote is unable to unlock and lock the doors of your car, it is likely that the main remote isn't functioning. The most common causes of key malfunctions for car remotes are battery or circuitry issues.
Battery
It is not unusual for the battery in the car key fob to degrade. It is relatively easy to change out batteries, but it is important to ensure you select the correct one; you can look in your owner's manual or contact the dealer for the manufacturer to find out what kind of battery you need. It's recommended to inspect the battery compartment thoroughly since dead batteries may leak harmful chemicals that can damage the remote. If changing the battery doesn't fix the problem, there may be other issues that require attention from a professional. For key fob repair , if the buttons seem to be stuck or broken it could be necessary to disassemble the remote and rework its parts. It is also possible to reprogramme the vehicle to recognize the new fob.
Buttons
Due to repeated use, key fobs can become worn and dirty. This is not unusual, but it can cause buttons to stop working or require a long press to function. This can be frustrating particularly when you're away from home and have to switch on your car. Even broken or damaged buttons can be fixed with a little effort and tools you already have at home.
First, check that keys repair are charged correctly and that the indentation on the back of the button is filled. Open the remote carefully and look over the circuit board. Look for signs of rust or other signs the buttons have been damaged or worn out. For example 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 is damaged or where conductive painting is missing. Don't rub too hard in order to damage the conductive paint and prevent the button from firing when it is pressed.
Also, make sure to inspect the battery connector's terminals for any loose solder connections. If this is the case, simply reconnecting them could restore functionality to the button. You can use the same process to restore functionality to any other loose connection in the fob.
If any of the rubber buttons at the front of the keyfob isn't working or need to be pressing very hard the graphite disks on the back of the button could have worn out and require replacement. You can usually do this by rubbing a pen over the disks. This will bring the button back to life.
If none of these solutions work, or if you still are unable to get the button to respond when you press it hard, it is possible that the circuitry is failing. It is possible to fix this by cleaning and re-soldering your fob however, you should have a spare in case it doesn't work.
Circuitry
The circuit board of the remote control could be dirty regardless of whether the buttons on the key fob function or not. This issue can be fixed by a thorough inspection. Broken cases and water are the most common causes of dirty boards. A damaged case can allow water and other debris to get in and short out the electronic components. Water can also get through pins and vias, which are the tiny connectors found on the board.
If you're able to open your key fob and you don't mind making a mess, we can remove the buttons from their sockets and put in new ones. It's also worth checking the connections between battery terminals. They can get very filthy and if they're not tight enough, the buttons might not work or even stay in their down position. Soldering the terminals and buttons back in place is usually all that's required to return a non-working key fob to functioning condition.
Non-Remote transponder chips
The sealed non-remote chips are more durable than remote fobs, but they are susceptible to cracking in the event of a hole being drilled into them or in the event that a door handle of a car or lawnmower runs over them. Most of the time non-remote transponder chips fail, and this could be attributed to blowing fuses.
If you're not comfortable opening the key fob, you may remove the circuitboard and utilize a multimeter to check that the diode is operating properly. If you're not comfortable doing this, head to your local hardware store or Oreilly's and they will usually have an RF frequency tester that will tell you whether the key fob sending signals.
Programming
Key fobs aren't indestructible and can be damaged by a variety of factors. They may lose their connection with the receiver inside your vehicle because of shocks or a low battery, which calls for the reprogramming. A professional auto locksmith or main dealer can reprogram your key fob to get it working again. If resetting or replacing the keyfob is not working, you may need to replace it.
