If the key fob still won't unlock your car or start it then try holding the fob closer to the ignition switch. The radio transmitter inside the key fob is able to send a signal to car's onboard receiver from only a short distance, however it's only effective in the event that a battery-powered remote is within close proximity to the ignition.

Circuit Board Damage
A damaged circuit board may impact the performance and integrity of the device. It can also cause problems with the performance of other components and parts within the device. There are several ways to repair a damaged circuit. These techniques can bring back the functionality of your device and make it look brand new.
First, examine the device to determine the cause of the issue. This is especially important in the event that you're trying to resolve a complicated circuit board. For instance, you need to be aware of any burn marks or other physical damages to the circuit board. Also, you should test for proper voltage at different points on the circuit board. This can be done using an oscilloscope or multimeter dependent on the complexity of the circuit board.
Faulty components are usually the reason for an unsound circuit board. This could be caused by a damaged transistor or diode. In certain instances the issue could be caused by an unrepaired trace path. Traces are made of copper or silver and are susceptible to being damaged by physical damage, extreme power surges or metallic dust contamination and normal wear and tear.
Before you attempt to repair a circuit board, it is important to make sure that you have the tools and equipment needed. This will ensure that the repair goes as smooth as it could be. It is recommended to have soldering tools as well as sandpaper and a desoldering device at hand. You should also protect yourself from electrostatic discharges which can damage circuit boards. To prevent ESD you can connect your workstation to the ground or use an antistatic wrist strap.
Finally, it is important to clean the circuit board before beginning the repair process. This will help prevent further damage and will reduce the chance of mistakes. To clean a circuit board you can use a swab which is saturated with isopropyl alcohol (IPA) or a flux remover pen. It is also important to ensure that the soldering pads are clean and free from contaminants.
Finally, you should remove the extra tape from the repaired area. This will avoid any further damage to the pads or tracks. You can also use a craft knife to carefully cut the extra tape. When trimming, you need to be cautious not to cut any of the pads or tracks on the circuit board.
Copies
A key fob, also known as a small electronic device, allows access to and control of the features of a car without the use of a physical key. These devices receive many abuses and are not impervious to destruction. There are a lot of parts that can malfunction or break. Luckily, most of these components are repairable. The most common cause of failure is the contacts on the battery terminals or buttons, however there are many other things that can fail.
Car key fobs communicate with the vehicle using radio frequency. They have unique tags that match the car. When they are pressed, they send the tag data to the vehicle, meaning it can open or unlock the door or start the motor. A car key fob is more useful than traditional keys that require being in the ignition to enable the features.
Sometimes, it can be a bit confusing when the car key fob starts acting up. Most key fob issues aren't serious and can be fixed at home. Changing the batteries or cleaning could be all that's required to solve the problem with your car key fob.

A new one could be more convenient than trying to figure out what is wrong with the current key fob and it is much more secure than not having the ability to operate your vehicle.
You can buy a replacement key fob from the dealer or auto locksmith, depending on the make and model of your vehicle. The dealer will also reprogram your new fob to work with your vehicle.
Certain car makers have apps that you can download to your smartphone that will allow you to open the doors and start the engine when you lose the key fob or isn't working. This is a good option for those who have spare keys and want to keep their vehicle's security while they are working on fixing the key fob.
