Dead Fob Battery

However, that's not always the solution to the issue, since you may also have a problem with the connection on one of the battery connector's terminals.
The car manufacturers are aware of the potential issue, and frequently include a mechanical key inside the fob to be used in such an emergency. It is accessible by pressing the small release button or latch that is located behind the fob. (Check car key remote repairs for further details). By pressing this button, you can open the fob to reveal a key that you can use to unlock the car.
You will also need to be nearer to your vehicle in order to lock and unlock it. The transmitter of the fob is depleted in power when the battery dies. This limits its range.
The replacement of the battery is simple and fairly inexpensive. Make sure you purchase the button cell battery (which looks like an incredibly small silver coin) for your fob and follow the user guide or video on how to remove the old battery. Then, simply replace the new battery in the same orientation that the previous one was inserted (the positive side should be facing upward towards the buttons). After reassembling the fob, test its start and lock functions as well as unlock/lock functions to be certain the new battery was placed correctly.
You can unlock some key fobs by looking for the latch, screw, or switch on the back and then prying the fob apart. You'll need the fob in order to work with your vehicle, so be careful not to harm it! If you're not confident making this change yourself it's also possible to take your key fob to an expert.

Fob Is Not Working
The first thing to do if your key fob isn't working is to replace the batteries. This is the fastest fix and will likely resolve the issue. If your fob still does not work after changing the battery, it could be caused by damage.
Damage can occur to your car key fob for a variety of reasons, such as physical trauma, water exposure or a corroded circuit board. These issues may prevent your key from sending a signal to the vehicle's receiver and prevent your car's doors and/or ignition from locking or turning on. It is possible that you will need to have a professional replace the fob if it's damaged.
Similarly, the buttons on your device could have become worn out with repeated use. The rubber may wear out and make the buttons less 'clicky' or springy. They also may stop registering your presses. You could try wiping the buttons down and adjusting them, but it is usually best to get the fob examined by a professional to make more extensive repairs.
Make sure that the battery you are using is exactly right for your fob. You can find a list online or in many hardware stores. Check the owner's manual or the engraving on the fob to find out more. If the battery is not the right fit it could be a problem transmitting strong signals or providing enough power to internal components.
In rare instances it could be the case that the problem is not with your key fob, but more with the vehicle's receiver or electronic components. You can test this by using a physical key to open the door and then trying to start your vehicle using the inductive backup system (if available). If the physical key you have not work or open your car, you should have an expert check the receiver and electronic components to make sure they're functioning properly.
Fob is damaged
A key fob contains many components that work together, and one failure can cause others to fail. When a key fob stops functioning, it's vital to determine whether there's an obvious cause like a cracked case or a malfunctioning internal component. It's also essential to examine other areas of the vehicle such as the lights and horn to determine whether they're functioning normally.
If the key fob is damaged, it's recommended to get a replacement from your dealer or an auto locksmith rather than trying to repair it. It could be necessary to reprogramme the fob to connect to your car. This is not something you can do at home, and requires special equipment.
The buttons on a key fob utilize contacts to transmit signals to the circuit board on the key fob however, they may wear out over time. This is more common if you drop the fob or leave it in a hot climate.
Over time, the internal wiring in a key fob can also get worn out. It can lead to the button not working when pressed, or only works when pressed very strongly. It could also result in the car not starting or unlocking when the fob is pressed.
Most fobs come with a plastic cover that can be opened and then cleaned with soap and water. This can bring a keyfob back to its original function. It's an excellent idea to clean it often to avoid dirt damaging the inside.
A damaged battery is usually the reason the key fob will not work or turn on. The majority of car dealers and mechanics can replace the battery in a short time. If you are comfortable with the installation then you can buy a new one at the big-box or a hardware store, and follow the instructions on YouTube or in your owner's guide.
The most likely scenario is that the key fob has internal damage, for example cracks within the case, tiny electronic components that aren't fully attached to the circuit board or bent or corroded contact points for batteries. If any of the above is the scenario, it's a great idea to talk to an auto locksmith or the dealer for a recommendation on a replacement and help to program it to your vehicle.
Fob Isn't Programming
Car key fobs are a convenient option that lets you unlock your car doors and start the engine. They can also cause frustration when they stop working or seem to work intermittently. In some cases, the problem may be as simple as replacing the battery however, in other instances it may require an even more complex repair. The first step is to determine the reason for why the fob isn't functioning properly.
The most frequent reason for a fob not working is that it doesn't recognize your vehicle. This happens if the connection between the remote and your car is broken. This connection can be reset without the need for costly key fob repair.
When the key fob is not sending a clear signal, other problems could occur. This can occur if the key is damaged or the battery is dead. In either situation, try to resync the key with your vehicle. You can do this by following the directions that come with the key fob. It's also an excellent idea to keep a spare key with you to utilize it in the event that your primary key isn't working.
It's possible that the fob doesn't receive a strong enough signal from the car. This could be due weak batteries in the car or interference from wireless devices or an antenna issue. You can test the fob and determine whether this is the cause by using an external tester. If the tester doesn't light up when any of the buttons are pressing, the battery may need to be replaced or the fob could be broken.
Another reason that the fob not sending an adequate signal is that the immobilizer system in your car is preventing it from doing so. This could happen if the fob's programming isn't correct to your vehicle, or in the event of a software issue.
If you're not able to resolve the issue, or it's not worth the effort of trying to repair the fob, then look into buying a replacement. Many online retailers offer affordable options and some can be delivered directly to your home.
