Remote Key Fob Repair
Modern vehicles come with remote controls that can be used to lock, unlock, and start the vehicle. Like any high-tech piece of equipment, there can be problems.
Usually these are very simple to fix. It is as easy as resetting the device which you should be able to do by following the instructions for resetting in your owner's manual.
Check the Battery
The remote control is powered by the battery inside the key fob. The battery is a small component that is inexpensive and needs to be replaced regularly to maintain the functionality of the key fob. There are a variety of reasons your key fob may not be functioning properly, besides the battery. This could be due to physical damage, exposure to water or internal component failure. Whatever the reason, if your key fob's sensor is not responding, it's time to replace its battery.
First, ensure that you have the correct size battery. The majority of modern key fobs are powered by a three-volt CR2032, which is easily available in a wide range of stores. The majority of these batteries are stamped with the size on one of the edges of the fob. A quick search for the name of your vehicle's brand should help you locate the specific type of battery it takes.
Take your key fob apart carefully and remove the existing battery. Take a photo of the inside of your fob to ensure that you put it back in the correct way. This simple step can save you from buying an entirely new fob if you make an error when making it back together.
Certain key fobs also come with a mechanical backup key known as an emergency blade. It's located inside the key fob and permits you to open the driver's side door in case the remote control isn't working. To access the blade of the key, you must locate the notch in the middle of your fob. The notch is typically covered by the plastic casing of the fob.

Most modern key fobs have a voltmeter built into their casings, however you can also purchase a multimeter for a few dollars at most hardware stores. Generally, the battery should be reading 3.0 volts or more. If it is below that level, it could indicate a battery in its final stages and must be replaced immediately.
Check the Buttons

They can cease working after some time, especially if they are used often or if they have been subjected to physical abuse. Fortunately, the majority of times it's easy to determine and repair a problem with a remote key fob, and changing the battery is often all that is required.
Modern car key fobs include several buttons that can perform various functions. For example, they can unlock and lock the doors and activate the panic button, and open the trunk. When a button on the fob is hit, it sends a radio code to a receiver inside the vehicle. Some fobs also come with a button that will start the engine, which can be particularly useful in cold winter mornings and hot summer days.
The buttons on a key fob reset by simply snapping it off and ensuring whether they're not damaged or stuck. Key fobs aren't made to be removed, but the battery connectors on a key fob can be loose as time passes. Soldering is a method to connect the button contacts to the circuit board if they have been disconnected. This will allow the fob to function again.
If a fob is damaged or dropped, the buttons may be damaged, misaligned, or out of alignment. These types of problems are typically more difficult to repair on your own but can usually be addressed by a local auto shop that has the right equipment and experience.

The resultant moisture can cause destruction on the electronic components inside, causing numerous malfunctions. The good news is that a key fob can often be saved from the brink of death by drying out thoroughly and following a few easy steps.
