Car Key Fob Repairs
Key fobs of today are more than just a way to unlock and start cars. This extra complexity can lead to expensive repair bills in the event that it malfunctions.
It's important to know that the majority of fobs are powered by flat-watch-style batteries which can be replaced at home. You may find that a simple reset can bring your fob back to life.
Battery Replacement
The most common reason a key fob stops working is because of a dead battery. It's easy to fix and worth trying before you spend money on a replacement fob. Simply take your car to a local auto parts store or hardware retailer that stocks button cell batteries and purchase an alternative. 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 for opening and replacing the battery on the particular type of fob.
The majority of fobs have two halves that snap together- you'll need to gently pry the sides apart to access the battery. It's usually a screwdriver or some other tool that has a flat, thin blade. You can insert your tool into a slot on the bottom of the key fob. You might also want to look for tiny pieces that may come loose while working.
Once you have the new battery, place it in the same way that you removed the old one. The positive (+) side should be facing the buttons and the reverse (-), the markings on the compartment for the battery.
Push a button to test the fob. If it doesn't work, you may have a problem with your car that requires a specialist to repair or replace.
Some key fobs require special tools to open and close, and the connections inside may be delicate and susceptible to corroding. In these situations, the best option is to speak with a expert or dealer. When replacing a battery, be gentle and follow your owner's instructions. You may be able to find a similar battery at a discounter or a big-box retailer but you'll have to check the owner's manual to make sure that it's compatible with your vehicle.
Replacing the Internal Key
Most key fobs contain a physical mechanical key, but it's hidden inside the fob to keep it from being stolen. If the battery inside the fob fails, a blank key is left behind that can be used to open doors and trunks. In some cases, this key can even start certain cars. Most people don't realize that they can avoid a trip to the dealership by replacing the fob's batteries. The flat watch-style battery is found in most modern fobs. These batteries can be found in hardware stores and auto parts stores. Choosing the right type of battery is crucial, however. The wrong kind can damage the electronic circuitry, causing the fob to fail sooner.
If you try replacing the battery and discover that the issue persists it could be an indication that something else is happening with your car. Go through the owner's manual to determine if there's a reset procedure that will bring the fob back to the factory program. If key repair shop near me doesn't help, 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 malfunction due to malfunctioning transmitter receivers. They are usually found close to the steering wheel, or on the dashboard. They transmit signals that allow you to unlock your car and begin it using the fob. It is possible that you will need to get closer to the car in order to make it work.
A professional may need to open the case of the fob to replace the transmitter. A simple screwdriver is enough to accomplish the task however, some fobs have complicated release mechanisms that require a specialized tool or specialized equipment that is available only at a dealer. This is a job that should be performed by a qualified mechanic to avoid damaging the fob and yourself.
Reprogramming the Key
A key fob that's not working may simply need an upgrade in battery. These batteries are easily found in home improvement and pharmacy stores and are affordable. This is a great method to start before you purchase an entirely new key fob.
You can also change the programming of your key fob on your own If you follow a few basic steps. The procedure may differ for different vehicles, so you should read the owner's manual and study the specific model of your vehicle. One key fob might require that the ignition be turned on while changing the program. Another might need the key to be removed and inserted several times.
The basic procedure is simple. First, make sure the new battery is in place. Close all doors, with the exception of the driver's door. This will ensure that the new key fob can communicate with the vehicle in a proper manner. After that, put the old key back into the ignition and turn it on to the ON position, but don't start the engine. Press the lock button while aiming the fob towards the receiver for transmission. It is usually located on the front above the mirror. Within a short time frame the key will announce to the vehicle that it's been programmed by cycling the doors locks or emitting an emitted sound. This can be a tricky process, so pay close attention to timing and don't over-press the button.
If the key fob won't work after reprogramming, try using new batteries. If the issue persists, you may want to visit your local dealer or locksmith. A professional locksmith will have the tools and equipment needed to reprogram your car's fob or create a new one if needed.

However, he's had the need to turn away customers with European models because he doesn't have the expensive equipment required. The majority of aftermarket fobs can be programmed, but you should always consult your local car dealer to find out the cost.
