10 Signs To Watch For To Get A New Remote Key Repair

How to Fix a Key fob key repair That isn't Working

If your key fob doesn't work, you can fix it with a few simple steps. The first step is to be sure it's not the backup remote.

If the backup is able to lock and unlock your car doors it is most likely an issue with the main remote. Most car remote key failures result from circuitry or battery problems.

Battery

The battery in the key fob could get worn out over the course of time. It is relatively easy to replace batteries, but it is essential to ensure that you choose the correct type and you can consult your owner's manual, or contact the dealer of the manufacturer to determine the type of battery you need. It is also important to inspect the battery compartment, since dead batteries can leak toxic chemicals that could damage the remote. If replacing the batteries doesn't solve the problem, it may be that there are other issues that require professional attention. For instance, if the buttons appear stuck or broken It may be necessary to disassemble the remote and rebuild its components. You can also try reprogramming the vehicle to recognize the new key car repair fob.

Buttons

Through frequent use, key fobs could get dirty and worn. It is not unusual for buttons to cease working, or to require a long push to make them work. This can be frustrating especially when you're away from home and have to turn on your car key repairs. Even broken or damaged buttons can be fixed with a bit of time and tools you already have at home.

First, make sure that the batteries are correctly installed and that the indentation on the back of the button has been filled. Then, carefully open the remote and inspect the circuit board. Look for signs of corrosion or other indications that buttons are worn out or damaged, such as missing paint that is conductive. Use the Q-tip, dipped in alcohol, gently clean any membrane contacts that have become damaged or where conductive paint is missing. Avoid rubbing too hard, since this could cause damage to the conductive painting and prevent the button firing when pressed.

Check the battery connector terminals carefully for any loose solder connections. Soldering them back to their original position can restore the button's functionality If this is the case. The same process can be used to restore function to any loose connections within the fob.

In the end, if any of the buttons made of rubber on the front of the key fob stop working or require a very difficult press to function, it is likely that the graphite disks that are on the back of the button are wearing down and need to be replaced. It is usually done by rubbing a pencil over the disks. This should bring the button back to life.

If all of this doesn't help or if the button does not respond to a firm press It could be the case that the circuit board itself has become damaged. This can be fixed by a quick clean, and refitting, but it's ideal to have a spare fob in case this method does not work for you.

Circuitry

The circuit board in your remote control could be dirty regardless of whether the buttons on the key fob work or not. A thorough examination is usually enough to fix this problem. Water and broken cases are the most common causes of dirty boards. A broken case can let water and other debris into the circuit board, causing it to short out. Water can also eat away at pins and connectors that are small on the board called via's.

If you're handy enough to open up your key fob and aren't afraid of some mess, we can remove the solder from the buttons and solder new ones in their place. It's also worth checking the connections between the battery terminals. They can become very dirty and if they're loose, the buttons might not work or even stick in their down position. Soldering the terminals and buttons to their proper positions is usually enough to bring a non-working fob back to working.

Non-Remote transponder chips

Sealed non-remote transponder chips are much more durable than remote fobs that have them but they can be damaged by a hole that is drilled into them or run over by a lawnmowers blade or car door handle. Fuse failures are usually the cause of non-remote chip failures.

If you are not comfortable opening the key fob, take the circuit board off and use a multimeter to verify that the diode is operating properly. If you're not comfortable with this, go to your local Oreilly or hardware store and test their RF frequency tester. This will tell you whether the key fob sends an RF signal.

Programming

Key fobs are not indestructible and can be damaged by a variety of factors. They may lose their connection with the receiver inside your vehicle due to shocks or low battery, which calls for reprogramming. A professional auto locksmith or main dealer can reprogram your key fob to get it functioning again. If resetting or replacing the keyfob is not working, you may need to replace it.
