The History Of Car Key Fob Repair
Car Key Fob Repairs
Key fobs today do much more than unlock and start vehicles. But that extra complexity can add up to expensive repair costs if one of them breaks.
The good news is that the majority of fobs have flat-watch-style batteries that are simple to replace at home. It is possible that a reset can bring it back to life.
Battery Replacement
The most common reason a key fob stops working is because of the battery being dead. This is a simple repair, and is worth a try before you spend money on a new fob. Simply drive your car to an auto parts store or hardware retailer that sells button cell batteries and pick up a replacement. You can also consult your owner's manual (or, if you don't have one, YouTube is full of videos from people explaining how to do it) for specific instructions on opening and replacing the battery on your particular type of fob.
You'll need to gently pull apart the sides of most fobs to reach the battery. You'll require a small flat-bladed screwdriver, or another tool with a thin blade. It's a good idea to look for a groove along the lower edge of the fob that you can use to place your tool between. You might also want to be on the lookout for small pieces that could fall off while working.
Install the new battery in the same way you removed the previous one. Make sure that the positive (+) side is facing upwards towards the buttons, and that the negative (-) side of the battery is aligned with the markings inside the battery compartment of your fob.
Press a button to test the fob. If it doesn't work, there may be a problem with your car that needs to be fixed or replaced by a professional.
Certain key fobs require special tools to open and close them, and the contacts inside can be fragile and susceptible to corroding. In these cases, the best option is to speak with a expert or a dealer. If you're looking to replace batteries, you should be very gentle and follow the instructions that are specific to your owner's manual. You may be able to locate an identical battery at a big-box store or discounter, but be sure you read the owner's manual to ensure it is compatible with your vehicle.
Replacing the Internal Key
To guard against theft, many key fobs are equipped with an electronic key inside. If the battery inside the fob goes out it will leave a blank key left behind that can be used to unlock trunks and doors. In some cases, this key can even start certain vehicles. Most people don't know this, but they can save themselves having to go to the dealership by simply replacing the fob's battery. The majority of modern fobs utilize flat watch-style batteries that are easy to find in auto parts stores and hardware shops. It is crucial to choose the correct kind of battery. A wrong type of battery can harm the electronic circuitry, which can cause the fob to fail faster.
If you replace the battery, and the problem persists, it could be an indication that something else is wrong with your vehicle. Go through the owner's manual to determine if there's a reset procedure that can restore the fob to factory-setup. If that doesn't help, you'll need to go to a dealership or an independent shop that specializes in vehicle-security systems and fob programming.
Fobs may also malfunction due to malfunctioning transmitter receivers. These are usually built into the dashboard or close to the steering wheel, and transmit signals that allow you to unlock and start your car using the fob. If you notice that you're being required to get closer and closer to your car to get it to work, there's a good possibility that the transmitter is not working.
It might be necessary for a professional to access the case of the fob in order to replace the transmitter. A simple screwdriver can usually suffice, but some fobs require a specialized tool or special equipment that can only be found at a dealership. It's best to have a certified mechanic handle this job to ensure you don't damage the fob or injure yourself.
Reprogramming the Key
Often a non-functional key fob simply requires a new battery. They are easily available in home improvement and pharmacy stores and are cheap. This is a good way to start before buying the new key fob.
Alternatively, you may be able to reprogram the fob on your own by following some basic steps. The process is different for different vehicles brands, so it's essential to read the owner's manual as well as research the specifics of your model. For instance, one key fob may require that the ignition be on while reprogramming it. One key fob could require the key to be inserted several times.
The general procedure is very simple. First, make sure the new battery is in place. Close all doors except the driver's door. This will ensure that the new key fob communicates with the vehicle in a proper manner. Put the old key in the ignition, turn it ON but do not start the engine. Press car key repair while aiming the fob towards the receiver of the transmission. This is usually located on the front, above the mirror. The key will inform the vehicle within a short amount of time that it is being programmed. This can be accomplished by turning off the door locks, or emitting an audible chime. This procedure can be difficult, so it's important to be aware of the timing and don't over-press the key button.
If the key fob won't work after reprogramming it, try replacing the batteries. If the issue isn't resolved then a visit to the dealer of your vehicle or a locksmith should be considered. A professional will have all the tools and equipment needed to reprogram your car fob, or even create a brand new one if needed.
Genesky says he's able to program newer fobs at around $200 to $250, based on the vehicle. But he's had to refuse customers with European models because there's no equipment they require. The majority of aftermarket fobs can be programmed, but you should always inquire with your local dealer to find out the price.
Finding a New Fob
If the key fob you have cannot be repaired, you may require a new one. Depending on the make and model, the dealership or an auto locksmith may be able to help. The dealership is likely to be the most expensive choice for a replacement fob, but it will also have the tools and software necessary to program your car properly. If you're looking for a cheaper option, a number of independent locksmiths can provide you with new car keys for a more affordable price.
It is a good thing to attempt to reset the fob you have before you decide to buy an entirely new one. Your owner's manual should outline the proper procedure for reset, which is usually just the pushing of a button which restores the original programming.
It's recommended to check your owner's manual and warranty information before deciding which place to go for the replacement of your key fob. If your car is still under warranty, or you have a car insurance policy or auto club membership that includes bumper-to-bumper protection, you may be eligible to receive a reimbursement for the cost of a new fob.
Finding the right location to purchase a fob can be a challenge. You might want to go to the dealer to get this service if you are driving a brand new car and want to be confident that your keyfobs are working properly. However, if you want an affordable alternative it is usually possible to find an independent locksmith who can provide the same services at a much lower cost.
