How to Repair a Key Fob
If you're unable to get your key fob to start the car, it may be time to go to an automotive repair shop. Before you go to an automotive service it is important to first verify some things.
The most obvious reason your key fob isn't working is that it has a dead battery. Fortunately, most key fobs are powered by standard 3V button cell batteries that are easily available at the majority of stores.
Dead Battery
The battery inside your key fob is responsible for the remote functions, which allow you to open or unlock your car's trunk, tailgate, or start the engine. The battery in your car key fob will eventually go out of service, just like any other battery. If this happens, it will cause havoc to your day and disrupt your schedule.
Fortunately, you don't need to wait for your key fob to fail before you can replace the battery. The process is simple enough to do it at home without needing to hire a mechanic, which is something to consider when it comes time to replace your key fob's batteries.
First, look for a slot along the seam that divides top and bottom. Use a coin or flathead screwdriver to insert into this notch and gently pry open the fob's halves. Once the fob is opened remove the battery that was in it. Replace it with a new one. You can snap the two halves of the fob together after you've inserted the new battery. Then test it. If the key fob still won't unlock your car or start it, try holding the fob closer to the ignition switch. The radio transmitter in the key fob is able to send a signal to car's onboard receiver from a short distance, but it's only effective if there's a battery-powered remote near the ignition.
It may not seem likely that your key fob will require a new battery but it's better to be prepared rather than wait for it to happen at the worst time. By learning how to replace the car key fob's battery, you can regain the remote functions that make your Chevy so wonderful to drive around Normal and Decatur.

Damaged Circuit Board
A damaged circuit board may affect the integrity and performance of the device. It can also affect the performance of other components or parts within the device. There are several ways to repair damaged circuits. These methods will restore your device's functionality and make it look brand new.
First, examine the device to determine the cause of the damage. This is especially crucial when you're trying to solve a difficult circuit board. For instance, you must keep track of any burn marks or other physical damage to the circuit board. Additionally, you should examine the voltage at various locations on the circuit board. This can be done using an oscilloscope or multimeter dependent on the complexity of the circuit board.
The faulty component is usually the cause of an unsound circuit board. This could be due to a defective transistor or diode. In other cases, the problem is caused by the trace pathway being damaged. Traces are made from silver or copper and are susceptible to damage due to physical damage, power surges, contamination by metallic dust and normal wear and tear.
You should make sure that you have the right tools and materials before you attempt to repair the board. This will help ensure that the repair is as easy as it can be. You should have soldering tools, sandpaper and a desoldering device at the go. It is also crucial to protect yourself from electrostatic discharge, which can damage the circuit board.

It is also important to clean the board before beginning the repair. This will stop further damage and will reduce the chance of the chance of errors. Clean the board with the swab which is soaked in Isopropyl (IPA) alcohol or a flux removal pen. In addition, you must make sure that the soldering pad is clean and free of any contaminants.

You can also use a craft knife carefully trim the extra tape. When trimming, you need to ensure that you don't cut any of the pads or tracks on the circuit board.

There are many parts that may fail or break. The majority of these components are repairable. Contacts to the battery terminal and buttons are the most frequently encountered failure point however, there are many other issues that could happen.
Car key fobs communicate with the vehicle using radio frequency. They have distinct tags on them that match the car, and when pressed they relay the information from the tag to the vehicle so it can open or lock the door, or start the engine. A car key fob is more useful than traditional keys that need to be in the ignition to enable the features.
