Car Key Fob Repairs
Key fobs today do a lot more than simply unlock and start vehicles. This added complexity can cause costly repair costs when it fails.
It's a good idea to know that a majority of fobs are powered by flat watch-style batteries that can be replaced at home. You might find that a simple reset is enough to make your fob work again.
Battery Replacement
The most frequent reason that a key fob doesn't work is due to a dead battery. It's easy to repair and worth a try before you invest in a replacement fob. You can buy a new button cell battery at your local auto part store or hardware retailer in the event that you already have one. You can also check your owner's manual (or, if you don't have one, YouTube is full of videos of people who explain how to do it) for specific instructions on opening and replacing the battery in the specific type of fob you have.
Most fobs come with two halves that snap togetheryou'll have to gently pull the sides apart in order to access the battery. You'll need a small flat-bladed screwdriver, or another tool with a small blade. You can insert your tool into a slot on the bottom of the key fob. You may also want to keep an eye out for small pieces that may be loosened while working.
Install the new battery in the same way as you removed the previous one. Make sure the positive (+) side is facing upwards towards the buttons, and that the negative (-) side of the battery is aligned correctly with the marks inside the battery compartment of your fob.
You can push a button to test the fob. If it doesn't work, there might be a problem with your vehicle that needs to be repaired or replaced by a professional.
Certain key fobs can be difficult to open and their contacts may be fragile and easily corrosion-prone. In these instances you should consult a specialist in your car or the dealer will likely be the best choice. If you're looking to replace batteries, you should be very gentle and adhere to the instructions that are specific to your owner's manual. You may be able to locate the same battery at a big-box store or discounter, however, make sure to check the owner's manual to ensure it's compatible with your car.
Replace the internal key
Most key fobs contain a physical mechanical key that is hidden within the fob to prevent thieves. When the battery in the fob dies it will leave an internal key blank which can open trunks and doors (and in some cases, start certain cars). The majority of people don't realize that they can save a trip to a dealership by recharging the fob batteries. The majority of modern fobs utilize flat watches-style batteries that can be found in hardware stores and auto parts shops. Using the correct type of battery is important, however. A bad battery can cause damage to the circuitry and lead to the fob's failure much sooner.
If the problem continues to persist after you replace the battery, it may be an indication that there is something else wrong with your vehicle. Go through the owner's manual to see if there's a reset procedure that can restore the fob to factory programming. If this doesn't help then you'll need to go to a dealership or an independent shop that is specialized in vehicle security systems and fob programming.
Fobs may also fail due to faulty transmitter receivers. They are usually found close to the steering wheel or on the dashboard. They transmit signals to allow you to unlock your car and start it with the fob. If you're being required to get closer and closer to your vehicle in order to make it work, there's a good chance the transmitter is failing.
A professional may need to open the fob's case to replace the transmitter. A simple screwdriver is usually enough to work, however certain fobs require a special tool or equipment that can only be purchased at a dealer. It is a good idea to have a certified mechanic handle this job to ensure you don't break the fob or hurt yourself.
Reprogramming the Key
A key fob that is not functioning simply needs a fresh battery. These batteries are easily found in pharmacy and home improvement stores and are inexpensive. This is a great method to start before you purchase an entirely new key fob.
Alternately, you might be able to re-program the fob on your own by following some basic steps. This procedure can differ between vehicles, so you should refer to the owner's manual and research the model you have. For example the key fob might require the ignition to be on while reprogramming it. Another key might require the key to be inserted and removed several times.
The process is straightforward. First, ensure that auto key repair is securely in place. Close all doors except the driver's door. This will ensure that the new fob is communicating with the vehicle in a correct manner. Insert the old key into the ignition and turn it on, but don't start the engine. Then, press the lock button on the fob, while aiming it at the transmission receiver, which is typically situated on the front of the vehicle above the mirror. In a short period of time the key will announce to the vehicle that it's being programmed by turning off the doors' locks or emitting a chime. This is a difficult process, so pay close attention to the timing and don't press too hard the button.
If the key fob doesn't function after reprogramming, you can try using a new battery. If the issue persists, you might want to check with your car dealer or locksmith. A professional will have all the tools and equipment to reprogram your car fob or design a new one, if required.

Genesky has been denied European models rejected due to the fact that they don't have the equipment needed. Fortunately, many aftermarket fobs can be programmed but it's always recommended to consult a car dealer first to determine what the cost is.
Getting a New Fob
If your key fob is damaged beyond repair, you could require an alternative. Based on the model and make, an auto locksmith or dealership may be able to help. The dealership is likely to be the most expensive option for a replacement fob but it also has the tools and software required to program your car correctly. Many independent locksmiths offer a new car key fob at a much lower price.
It's a good idea to attempt to reset your current device before you make the decision to purchase another one. The owner's guide should explain the correct procedure for reset. This is usually the result of a series of button presses that reset the factory program.
It is also recommended to check the owner's guide and warranty information to see whether you are eligible for a replacement fob for your key. If your car is under warranty, or you have a car insurance policy or auto club membership with bumper-to-bumper protection, you may be eligible for reimbursement for the cost of the new fob.
The process of getting a fob can be simple enough however, finding the right location to get it done isn't easy. If you have a relatively new car and want the assurance with knowing that your key fobs are in working condition, you may be better off going to the dealership to get this service. If you are looking for a cheaper alternative, it's possible to find a locksmith that will provide the same service for a lower price.
A professional locksmith is a great option if you're not comfortable doing this kind of work. They're trained and equipped to replace or reprogram key fobs for cars of all types and do it quickly. A locksmith can also visit your office or home, which is convenient for many. They can also cut and program keys on the spot if you've lost keys. This is great for those who don't want to leave their vehicle without a key.
