11 Methods To Redesign Completely Your Remote Key Repair
How to Fix a Key Fob That isn't Working

If your key fob does not work then you can fix it by following some simple steps. First, make sure that it's not your backup remote.

If your backup remote can unlock and lock the doors of your car, it is likely that the main remote isn't working. The most common causes for key problems with your car remote are issues with the circuitry or battery.

Battery

It is not unusual for the battery in the key fob for cars to wear out. It is quite simple to replace a battery, although it is crucial to ensure you select the correct one and you can consult your owner's manual or contact the dealer for the manufacturer to determine the type of battery you need. key repair near me is also important to inspect the battery compartment, since dead batteries can leak caustic chemicals that can harm the remote. If changing the batteries doesn't solve the issue, it may be that there are other issues that require professional attention. If the buttons are broken or stuck for instance, it may be necessary take the remote apart and rework each component. You can also try reprogramming the vehicle to recognize the new device.

Buttons

Due to frequent use, key fobs could wear out and become dirty. This is not uncommon, but it can cause buttons to stop functioning or require a hard press for them to function. This can be very frustrating, especially if you are away from home and you need to start your vehicle. Even broken or damaged buttons are often fixable with a little effort and tools you already have at home.

First, make sure that the batteries are correctly placed and that the indentation at the back of the button is filled. Open the remote carefully and look over the circuit board. Check for signs of rust or other signs the buttons have been damaged or worn. For example, conductive paint may be missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that is worn-out or has conductive paint missing. Do not rub too vigorously as this can damage the conductive paint, and block the button from firing when it is pressed.

Also, make sure to inspect the battery connector terminals for a loose solder connection. Soldering them back to their original position 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 within the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob stop functioning or require a difficult press to function it is likely the graphite disks that are on the back of the button are wearing down and require replacement. You can do this by rubbing a pen over the disks. This should bring the button 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 has failed. It is possible to fix this by cleaning and re-soldering the fob however, you should have an extra in case it does not work.

Circuitry

The circuit board in the remote control could be dirty, regardless of whether the buttons on the key fob are working or not. A very thorough inspection is often enough to resolve this problem. The most frequent causes of dirty circuit boards are water and damaged cases. A damaged case could allow water and other debris to get into the circuit board, causing it to short out. Water can also destroy pins and small connectors on the board, which are known as via's.

If you're able to open your key fob, and you're not afraid of making a mess, we can take off the buttons and then solder new ones in their place. It's also worth looking at the battery terminal connections. If they are loose, the buttons may not function or get stuck in their down position. Soldering the terminals back to their proper positions is usually enough to bring a non-working fob back to working.

Non-Remote transponder chips

The non-remote chips that are sealed are more durable than remote fobs, but they can be cracked in the event of a hole being drilled into them or if a car door handle or lawnmower runs over them. Most of the time, non-remote transponder chip malfunctions can be attributed to an exploded fuse.


If you are not comfortable opening the key fob, you may take the circuit board off and use a multimeter to determine if the diode is working properly. If you're not confident doing this, visit your local hardware store or Oreilly's, and they will usually have an RF frequency tester that will tell you whether the key fob is sending signals.

Programming

Key fobs are not indestructible and are susceptible to being damaged by a lot of things. They can break their connection with the receiver in your vehicle because of shocks or a low-battery, which requires changing the program. A professional auto locksmith or a main dealer will be able to reprogram your key fob and get it functioning again. In the rarer case that resetting and repairing your key fob doesn't work it could be the time to replace it entirely.
