Car Key Fob Repairs

Today's key fobs do a lot more than unlock and start cars. However, that added complexity can add up to high repair bills if one of them breaks.

It's a good idea to know that most fobs are powered by flat watch-style batteries which can be replaced at home. It is possible that a simple reset is enough to bring your fob back to life.

Battery Replacement

A dead battery is the most common reason for the fob's key not working. It's simple to solve and is worth a try before you spend money on a replacement fob. Simply drive your car to a local hardware or auto parts retailer that sells button cell batteries and purchase the replacement. You can also consult the owner's manual (or YouTube for videos explaining how to replace the battery) for specific instructions on how to remove and replace the battery inside your fob.

You'll need to gently pry apart the sides of most fobs in order to access the battery. You'll typically need a small screwdriver or another tool equipped with a thin, flat blade. You can wedge your tool into a notch on the bottom of the key fob. It is also advisable to look out for small pieces that might break loose as you work.

Once you have the new battery, place it in the same way that you removed the old one. Make sure that the positive (+) side is facing upwards towards the buttons and that the negative (-) side of the battery is aligned correctly with the markings inside the battery compartment of your fob.

Test the fob to see whether it is working by pressing a button. If it doesn't work, you might have an issue with your vehicle that requires a specialist to fix or replace.

Certain key fobs can be difficult to open and their contacts may be fragile and easily corrosion-prone. In these instances the best solution is to consult a car expert or dealer. If you're looking to replace the battery, make sure to be very gentle and follow the instructions specifically in your owner's manual. You might be able to find an identical battery at a big-box store or discounter, however, make sure you check the owner's manual to make sure it is compatible with your vehicle.

Replacing the Internal Key

To protect against theft, the majority of key fobs come with a mechanical key hidden inside. When the fob battery dies, it leaves behind a blank internal key that can unlock trunks and doors (and in some cases, start certain vehicles). Most people don't realize they can save a trip to a dealership by recharging the fob batteries. The flat watch-style battery is found in the majority of modern fobs. These batteries can be found in auto parts stores and hardware stores. It is crucial to choose the correct kind of battery. The wrong type can damage the circuitry, causing the fob's failure earlier.

If you change the battery, and the issue persists, it could be a sign that something else is happening with your car. If you have an owner's manual and you're not sure, try to determine if there is a reset option available to restore the fob's factory programming. If this doesn't work then you'll need to visit a dealership or an independent shop that specializes in vehicle security systems and fob programming.

Fobs can also malfunction due to malfunctioning transmitter receivers. They are typically located on the dashboard or near the steering wheel, and they send signals that allow you to unlock and start your car with the fob. It is possible that you will need to get closer to the car to enable it.

A professional might need to open the case to replace the transmitter. A simple screwdriver can usually work, however certain fobs require a special tool or equipment which can only be found at a dealer. This is a job that should be done by a qualified mechanic to ensure that the fob is not damaged and yourself.

Reprogramming the Key

Often a non-functional key fob simply requires a new battery. Since these batteries are inexpensive and easily available at pharmacies and home improvement stores, it's a good first step before buying a new car key fob.

Alternatively, you may be able to re-program the fob yourself by following some basic steps. This process varies between vehicle manufacturers, so it is important to read the owner's manual and research the specifics of your particular model. For example the key fob might require that the ignition be turned on while reprogramming it. One key fob could require the key to be inserted multiple times.

The general process is simple. Make sure that the battery is securely in place. Then, get into the driver's seat and close all doors, excluding the driver's side door. This will ensure that the new key fob is communicating with the vehicle properly. Insert the old key into the ignition, turn it on, but don't start the engine. Press the lock button while aiming the fob toward the receiver for transmission. This is usually located on the front above the mirror. The key will signal to the vehicle within a short period of time that it is being programmed. This can be done by cycling the door locks or by emitting an audible chime. This can be a tricky process, so pay attention to the timing and avoid pressing too hard the button.

If the key fob won't work after reprogramming, try replacing the batteries. If the problem persists you might want to visit your car dealer or locksmith. A professional locksmith will have the tools and equipment needed to reprogram the car fob, or even create a brand new one if necessary.

Fortunately, many aftermarket fobs are programmable but it's always best to check with an auto key fob repair dealer first to see what the cost is.
