How to Repair a Car Key Fob
Your key fob is likely to be tossed around a lot. This can cause its buttons to become stuck or broken. If you need to, give it a good cleaning and replace the battery.
Most cars are powered by the coin-style battery available at big box stores, home improvement retailers and pharmacies. However certain models require specialized programming equipment that only dealers have.
Dead Battery
The car key fob makes it easier to start your car and even get it into. But what happens when you press the button a few times and your car isn't responding? The most common reason for this is the battery is dead. Fortunately, the battery is simple to replace. You can purchase replacements at auto parts stores and supermarkets as well as home improvement centers.
Other features that are available on the key fob might not work. This could be due to an issue with the mechanical system, an electrical problem or even a programming error within the car's receiver. In these instances it's best to call a professional.
The majority of manufacturers include a mechanical slot on the fob that can be used in case of dead cells. In most instances, a cover is put on the handle of the fob in order to cover the key slot. The physical key can be put into the slot which allows you to unlock your door and start your car. Make sure to insert the key fob after you have started the vehicle!
If you have a Ford with SYNC Connect, you can start the car with the key fob. The majority of SYNC Connect equipped Ford vehicles have an alternative "E-blade" in the cupholder. This key can be used to press the starter button in the event that your key fob isn't able to start the vehicle. For the best use of this feature, ensure that the battery is fully charged. You can also refer to the owner's manual to find out how to use it.
If key fob repairs continues to have issues after replacing the battery on your key fob, you may need to contact a locksmith or your dealer to get the fob or battery repaired. In some instances the key fob could be programmed to your car by replacing the battery at the dealership or at certain Interstate All Battery Center locations. This will only work so long as the antennas and circuit board are not damaged.
Damaged Buttons
The buttons on your car key fob are likely to endure a lot of wear and tear over the course of their lives. They're susceptible to droppings and also are frequently being carried around in purses and pockets. This could cause internal components to get damaged or loose, which will cause them to not respond to your pressing. This issue can be solved by a few simple steps, but you might be required to speak with a locksmith.
Apart from batteries that are dead, the most common reason a car key fob will not work is because it needs new batteries. These little coins-shaped batteries are relatively inexpensive, and it's not difficult to find them at large-box stores or hardware stores. You can also look up videos on YouTube and in your owner's manual which describe how to replace the battery on your key fob.
It is important to know that some keyfobs require specific steps to enter the appropriate programming mode for changing the batteries. In these cases, you'll need to consult your owner's manual and/or an auto locksmith that is reputable to ensure that you're following the proper procedure.
If the battery is not working, leaving your key fob in extreme temperatures could cause it to stop functioning. In this case you'll have to talk to an automotive locksmith or your dealer for a replacement fob.
If your key fob's buttons remain unresponsive, it could be that the contacts inside are worn out. These contacts are rubber-like and coated with an electricity-conducting film, but they can start to wear out over time due to repeated use. You can repair this by taking the key fob apart and placing a piece of metallic tape over the worn-out contacts.
It's important to remember that certain key fobs can be extremely difficult to open and can't be opened safely without specialized equipment only available at a dealership. If you attempt to open it with a screwdriver or another tool it's likely that you'll damage the internal circuit board and end up with an expensive repair bill than you might have otherwise needed.
Circuit Board Issues
The circuit board could be the reason for your key fob's not working as well as it did too. The circuit board is an electronic chip that's inside the case. It sends signals to the car that tell it if you want to lock the doors, open the trunk, or turn off the ignition. If the circuit board has been damaged, the key fob will not be able to send these signals.
If you're a tech expert you can fix a damaged circuitboard yourself. Begin by removing the battery and separating the rubber button and holder assembly from the circuit board. Clean the plastic frame and contacts with rubbing alcohol and a cotton swab. This should remove any rust that is preventing the circuit board from transmitting signals.
After reassembling your key fob, verify whether it's in programming mode. Usually, this requires switching it off and on several times, so be sure to consult your owner's manual to find specific instructions. Many car manufacturers have online videos that explain how to accomplish this. If you're not sure how to do this and you are not sure how, you can bring your key fob into an expert locksmith who is knowledgeable about the vehicle model you have.
Some modern key fobs have a built-in receiver that allows you to unlock your trunk and open the doors, and also switch on your ignition and start the engine from a distance. Generally, these are much more reliable and work across a wider range. If your key fob doesn't work as far as it did previously, it may have an internal problem that's not working properly or a faulty external antenna.
The most likely cause for the key fob not working is a dead or low battery. It's affordable and easy to replace. If the circuit board or buttons of the fob are damaged, it will require professional repair and reset. The majority of dealerships offer this service however, you can find a service that specializes in the brand of your car.

This is a case of searching in drawers, bags and under couches. Then, you'll discover it. But the best way to prevent losing your key fob is to taking precautions. If you're susceptible to forgetfulness or have a slight hint of ADD, make several copies and distribute them to your family and acquaintances so that you don't be sweating and cursing for four hours if you lose your key fob.
Most cars come with key fobs that let you lock and unlock your doors. You can also sometimes you can set off the alarm or open the trunk. However, a few of the more sophisticated models have even cooler features, such as the capability to summon your car with the touch of one button. This feature isn't available in all models, but if you have one of the cars that do it (Genesis GV60 and Hyundai Sonata are two examples), this is an amazing feature to have.
The good news is that if you have a spare key fob that's programmed to your vehicle, then you can use it to start your vehicle in the event that you lose the original. You can also talk to an automotive locksmith to have them create a new key fob that's was programmed to your specific vehicle.

Dealers are also able to do this but they'll require your vehicle to be towed as well as proof of ownership. But the good thing is that these services are affordable, especially when compared to buying a new key from your dealer, which can cost $200-$250.
