11 Ways To Totally Defy Your Car Key Fob Repair
Car Key Fob Repairs
Key fobs today do much more than just unlock and start vehicles. This added complexity could cause costly repair costs if it breaks.
It's a good idea to know that the majority of fobs are powered by flat-watch-style batteries which can be easily replaced at home. You might find that a simple reset is enough to allow your fob to function again.
Battery Replacement
The most frequent reason why a key fob stops working is due to an inoperative battery. It's a simple repair, and is worth trying 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 the 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 in the specific type of fob you have.
Most fobs have two halves that snap together- you'll need 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. It's a good idea to look for a notch along the bottom of the fob that you can wedge your tool between. You may also want to keep an eye out for tiny pieces that could break loose while working.
Insert the new battery the same way as you removed the previous one. The positive (+) side should face the buttons and the negative (-) the markings on the battery compartment.

Certain key fobs are difficult to open, and the contacts could be fragile and easily damaged. In these cases you should consult a specialist in your car or a dealer could be your best option. If you're looking to replace the battery, make sure to be very gentle and adhere to the instructions that are specific to the owner's manual. You might be able to find a similar battery at a discounter store or a big-box retailer but you'll have to check the owner's manual to make sure that it's the right one for your vehicle.
Replace the internal key
To protect against theft, the majority of key fobs come with an internal mechanical key that is hidden within. When the battery in the fob goes out, a blank key is left behind, which can be used to open trunks and doors. In certain cases, this key can even start certain vehicles. Many people don't realize this, but they can avoid a trip to the dealership by simply replacing the fob battery. The flat watch-style battery is found in the majority of modern fobs. These batteries are easily found in hardware and auto parts stores. It is important to use the right type of battery. A bad battery can cause damage to the circuitry, causing the fob's failure earlier.
If the issue persists after you replace the battery, it could be a sign that something else is wrong in your vehicle. If you have an owner's manual, check to see if you can use a reset procedure to restore the fob's original programming. If this 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 can also fail because of faulty transmitter receivers. They are typically located on the dashboard or next to the steering wheel, and transmit signals that allow you to open and start your car using the fob. You may have to move closer to the car to get it to work.
It may be necessary for a professional to open the case of the fob to replace the transmitter. A simple screwdriver can usually work, however certain fobs require a special tool or special equipment that can only be purchased at a dealer. This task should be done by a qualified mechanic to ensure that the fob is not damaged and yourself.
Reprogramming the Key
A key fob that is not working might just need a new battery. Because these batteries are cheap and readily available in pharmacies and home improvement stores, this is the ideal first step before purchasing a new car key fob.
You can also re-program your key fob by yourself by following some basic steps. This procedure can differ between vehicles, so you should consult your owner's guide and research the model you have. For instance, one key fob may require that the ignition be switched on while reprogramming the key. Another key might require the key to be inserted and removed repeatedly.
The procedure is simple. Make sure the battery is securely in place. Close all doors, with the exception of the driver's door. This will ensure that the new fob is communicating with the vehicle properly. Then, place the old key back in the ignition and turn it to the ON position, but don't start the engine. Press the lock button while aiming the fob towards the receiver for transmission. This is usually located on the left side, just above the mirror. In a short period of time the key will signal to the vehicle that it's been programmed by triggering the doors' locks or generating a chime. This can be a difficult process and it's crucial to pay attention to the timing and to not over-press the key button.
If the key fob won't work after reprogramming it, try using a new battery. If the problem persists then a visit to your car dealer or locksmiths should be considered. A professional locksmith will have the tools and programming equipment needed to reprogram your car's fob or clone the key if needed.

How do I get a new fob
If the key fob you have cannot be repaired, you might need to buy an entirely new one. Based on the make and model, the dealer or an auto locksmith might be able to assist. The dealership is likely to be the most expensive choice for a replacement fob but it will also have the tools and software required to program your car correctly. If you are looking for a less expensive solution, many independent locksmiths can offer you a brand-new car key fob at a lower price.
It's a good idea to try to reset your current fob before you decide to buy an entirely new one. The owner's manual should provide the correct procedure for reset. This is usually the result of a series of button presses which restores the factory settings.
You should also check your owner's guide and warranty information to see whether you are eligible for an alternative key fob. If your car's warranty is in good standing or you have an auto club or car insurance policy that covers bumper-to-bumper you could be eligible for a reimbursement on the cost of replacing the fob.
Finding the best location to purchase the fob you need can be difficult. You might want to visit the dealer to get this service if you are driving a brand new car and want to be confident that your key fobs are functioning properly. However, if you're looking for an affordable alternative it is possible to find an independent locksmith who can provide the same services for a lower cost.
A locksmith who is professional is a great option for those who aren't comfortable with this kind of work. They are skilled and equipped to reprogram or replace most types of car key fobs, and they can often complete the task quickly. Additionally, locksmiths can often come to your office or home to complete the task, which can be very useful for certain people. They can even cut and program keys on-site when you've lost keys, which is ideal for those who prefer not to leave their cars in the dark.
