Key Fob Repair Service
Key fobs take a beating. Depending on how they're kept and how often they're knocked around, their buttons may get stuck or damaged.
Most key fob issues are easy to fix. However, some issues are more serious and will require professional help. Locksmiths can be a huge help in these instances.
Dead Fob Battery
Car key fobs are pretty intelligent however, that doesn't mean they don't occasionally find themselves in the "not responding" zone. It's time to replace your battery if this happens. But that doesn't always solve the issue, as you may also have an issue with one of the battery connector's terminals.
The car manufacturers are aware of the potential problem, and they often add a second mechanical key inside the fob to be used in such an emergency. You can access it by finding the small release button or latch on the back of the fob. (Check the user manual for more details). Pressing this can allow you to unlock the fob and access an actual key that you can use to unlock your car.
Another sign that your fob's battery is dying is that you need to be closer to the car to open and lock it than before. The transmitter of the fob loses power when its battery dies. This limits its range.
It is relatively easy to replace the battery. Make sure you purchase the button cell battery (which appears to be like an incredibly small silver coin) for your fob and follow the user's guideline or video instructions on how to take out the old one. Then, simply replace the new battery in the same way that the old one was inserted (the positive side should face upwards towards the buttons). Test the lock/unlock and start functions of the fob after reassembling it. Make sure the new battery is installed correctly.
You can open some key fobs by locating the latch, screw, or switch at the back and prying the fob off. The fob will need to work with your vehicle, so make sure not to harm it! If you're not comfortable doing this yourself then you can take your fob to a professional. Many auto shops will swap the battery of a fob at a minimal cost as it's an everyday repair service. Some dealers will even complete the task for free based on the model and year of your vehicle.

In very rare cases it could be that the problem is not with your key fob but rather the vehicle's receiver or electronic components. If you have an inductive backup system, you can test it by opening the door using an actual key and start the car with the inductive backup (if it is available). If the physical key you have isn't able to open or start your vehicle then a mechanic should inspect the electronic components and receiver of your vehicle to determine if they are functioning correctly.
Fob Damaged

The internal wiring of a key fob may also become worn out over time. This could lead to the button not working when it's pressed, or only functioning when it's press extremely hard. It could also result in the vehicle not being able to start or unlock when the fob has been used.

Fob isn't programming.
Car key fobs are a convenient convenience that allows you to unlock your car's doors and begin the engine. They can also be a source of frustration when they stop working or seem to be working intermittently. In some instances, the issue can be solved by replacing the battery. However, in other cases, it might require a more complicated repair. The first step is to figure out the reason for the fob not functioning properly.
One of the most frequent causes of a malfunctioning fob is that it has stopped recognizing your vehicle. This can happen when the connection between your remote and your car is damaged. This connection can be reset without the need for an expensive key fob repair.
If the key fob not sending a clear signal, other issues could be experienced. This could happen if the key has been damaged or the battery is not functioning properly. In any case, attempt to reconnect the key with your vehicle. You can do this by following the directions included with the key fob. It's also a good idea to carry an extra key, so that you can use it in the event that your primary key isn't working.
It's also possible that the fob isn't getting a strong enough signal from the car. This could be caused by an insufficient car battery, interference from wireless devices, or an antenna issue. By using a remote tester you can test the fob to determine if it's the problem. If the tester does not light up when you press any of the buttons, it may be a sign that the battery has to be replaced or that the fob is broken.
Another possible reason for the fob not sending a strong enough signal is that the immobilizer system in your car is blocking it. This can happen if the fob's programming isn't correct to your vehicle, or if there is a software problem.
If you can't fix the fob, or it's not worth the effort to repair it, you should buy a new one. You can find low-cost options from numerous online retailers and some can even be delivered to your doorstep.
