10 Quick Tips About Remote Key Repair

How to Fix a Key Fob That isn't Working
If your key fob won't work, you can fix it by following some simple steps. The first step is to be sure that it's not your backup remote.
If the backup remote is able to lock and unlock your car doors then there's a likely issue with the main remote. Most problems with car remote keys are caused by circuitry or battery problems.
Battery
The battery inside the key fob could wear out over time. It is fairly easy to replace a battery, although it is crucial 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 also crucial to examine the battery compartment, as batteries that are not working properly can release caustic chemicals that can harm the remote. If replacing the battery does not fix the issue, there may be other issues requiring professional attention. For example, if buttons appear 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 device.
Buttons
Through frequent use, key fobs may wear out and become dirty. This is not atypical, but it can cause buttons to stop working or require a very hard press for them to function. This can be a hassle especially when you're away from your home and have to switch on your car. Fortunately, even worn out or malfunctioning buttons can often be fixed with just a bit of time and some of the materials you might already have in the house.
First, make sure the batteries are charged correctly and that the indentation on the back of the button is filled. Then, carefully remove the remote and inspect the circuit board. Look for signs of corrosion or other signs that the buttons are worn out or damaged, such as missing the conductive paint. Use a Q-tip dipped into 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 block the button from firing when you press it.
Check the battery connector terminals for loose solder connections. If this is the case, simply reconnecting them could restore function to the button. You can apply the same process to restore functionality to any other loose connection within the fob.
Finally, if any of the buttons made of rubber on the front of the key fob have stopped functioning or require a difficult press to function, it is likely that the graphite disks on the back of the button are deteriorating and need to be replaced. It is usually done by rubbing a pen over the disks. This should bring the button to life.
If none of this is helpful, or if the button still does not respond to a hard push It could be because the circuit board itself has become damaged. This can sometimes be repaired with a quick clean and replacing the solder, but it is best to have an extra fob on hand in the event that this method does not work for you.
Circuitry
The circuit board in your remote control may be dirty, regardless of whether the buttons on the key fob work or not. The issue can be solved through a thorough examination. The most common causes of dirty circuit boards is water and damaged cases. how to repair car key lock broken case can allow water and other debris into the circuit board, causing it to short. Water can also get through pins and vias, which are small connectors found on the board.
If you are handy enough to open your key fob, and don't mind making a mess, we can remove the buttons from their sockets and solder in new ones. It's also worth checking the connections between battery terminals. They can get very dirty and if they're loose the buttons might not function or even stick in their down position. Soldering terminals and buttons back to their proper positions is usually enough to bring a non-working fob 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 in them or in the event that a door handle of a car or lawnmowers is pushed over them. The failure of the fuse is usually to blame for non-remote chips failures.
If you're not comfortable opening the key fob, you can remove the circuitboard and utilize a multimeter to check that the diode is working correctly. If you're not sure with this, go to your local Oreilly or hardware store and utilize their RF frequency tester. This will inform you whether the key fob sends an RF signal.
Programming
Key fobs are subject to many abuses and aren't completely indestructible. They can lose their pairing with the receiver inside your vehicle due to shocks or a low battery, requiring the reprogramming. A professional auto locksmith or dealer can reprogram your key fob and get it functioning again. If, in the unlikely event that resetting or repairing your key fob fails it may be time to replace it all over again.
