They are typically very simple to repair. It can be as simple as resetting it which you should be able accomplish by following the resetting guidelines in the manual of your owner.

Check the Battery

The battery inside the key fob powers the remote control function. It's a tiny and affordable part that needs to be replaced regularly to ensure the fob's functionality. There are many other reasons your key fob might not be functioning properly, besides the battery. This could be due to physical damage, water exposure or internal component failure. Whatever the cause the key fob isn't responding and is not responding, it's time to replace the battery.

First, ensure you have the right size battery. Most modern key fobs are powered by a CR2032 three-volt battery which is easily found in many stores. The majority of these batteries are engraved with the size on one of the fob's edges. You can determine the type of battery your vehicle requires by searching for the brand name.

Once you have the right battery then carefully open your key fob and remove its battery. Take a picture of the inside of the fob to make sure you put it back together correctly. This simple trick will prevent you from buying another fob if you make an error when putting it back together.

Certain key fobs also come with an electronic backup key, also known as an emergency blade. It's located inside the key fob and permits you to access your car's driver's door in the event that the remote control fails to function. To access the key blade, you need to locate the notch in the center of the fob. The notch is typically an oval shape that is hidden by the fob's plastic casing.

If you want to be extra cautious, you can use a multimeter to check the voltage of the battery. The majority of modern key fobs have a built-in voltmeter, but you can buy a multimeter in the majority of hardware stores for a few dollars. Generally speaking, the battery should be reading 3.0 volts or more. A reading that is lower than this could indicate that the battery is in its last days and needs to be replaced immediately.

Check the Buttons

Car key fobs may seem like little more than fancy modern, high-tech gadgets, but they aren't indestructible. Remotes can stop functioning after a period of time, particularly if they are used often or were subjected to physical abuse. In most cases it is easy to identify the issue and fix it with the remote fob. In most cases all that's needed is an upgrade to the battery.

Modern car key fobs come with multiple buttons that perform different functions. For example they can be used to lock and unlock the doors and activate the panic button and open the trunk. When a button on the fob is pressed, it sends a radio code to a receiver inside the vehicle. Some fobs have an option to start the car, which is useful on cold winter mornings as well as hot summer days.

The buttons on a key fob reset by simply taking it apart and checking whether they're not damaged or stuck. Key fobs aren't typically designed to be taken apart, but the battery connectors on a key fob can get loose as time passes. If the button contacts have been disconnected from the circuit board and need to be soldered, a simple job is enough to put them back in place and return the fob to full functionality.

If a fob gets damaged or dropped, the buttons may be broken, misaligned, or out of alignment. These issues are more difficult to repair on your own. However, a local auto shop can fix them with the right equipment and expertise.

It's always an excellent idea to have an extra key somewhere in the event that one that you frequently use fails to function. This will prevent you from being stranded without your keys repair or having to pay a large amount of money to have your vehicle towed back to the dealer. It is also advisable to look over your car insurance policy, car club membership or extended warranty coverage to determine if it covers the cost of replacing or programming the new fob.

Check the Casing

It's not uncommon for a keyfob to get wet. It could be the result of a swimming pool, a rainstorm, or even from your washing machine. The resulting water can play havoc with the electronics inside, leading to numerous malfunctions. The good thing is that the key fob can usually be kept from the brink of death by drying it thoroughly and following a few easy steps.

First, check whether the buttons function correctly. This usually means removing the buttons, cleaning them and reassembling them. If the buttons don't click back in or feel stuck, it's probably time to replace the remote.

You'll also want to check the case to ensure there's nothing blocking the functioning of the key fob. Use tweezers to open the case and take out the battery, but do not disassemble the circuit board or antennas. These have electric current running through them that keeps the key fob programmed to your car, and if you disturb those circuits, you'll need to go to a dealer or choose an Interstate All Battery Center location to reprogram it.

After you have removed and replaced the battery, it's an ideal idea to dry the key fob out by putting it in an airtight bag that contains silica gel packets. This will prevent future moisture issues and help the battery last longer.

If the fob still doesn't work, you should visit a dealership or an independent shop that specializes in the model and make of your vehicle. They can re-program the fob's key fob repair service to your vehicle and hopefully restore it to its full functionality.

If all else fails, you can purchase a replacement keyfob online or in your local NAPA Auto Parts shop. These DIY remotes are just like the original fob, but are more affordable. They are easily paired to your vehicle with simple instructions. NAPA offers a variety of do-it yourself replacements that you can program within a matter of minutes.

Check the Connections

Sometimes your key fob might just stop working - even though it's programmed to your vehicle. This could be due to a number of factors that include malfunctioning contacts on the battery or buttons. It is possible to fix the issue yourself by performing a simple maintenance.

The first thing you need to ensure is that your backup remote can lock and unlock the doors of your car. If it can't, you may have an issue with your primary remote key fob repair. If you aren't able to, it's time to try replacing the battery in the backup remote.

It's a good idea to take apart your key fob prior to replacing the battery and inspect the circuit board. Check for cracks in the solder joints. After that you can replace the battery and rebuild the key fob.

After you have replaced the battery and reassembled your key fob, make sure you test the connection to your vehicle. Insert a flathead mini screwdriver into the notch on the bottom of the key fob. From there, you can take apart the two halves of your key fob, and gently remove the circuit board. Be careful when inserting a new CR 2032 3V battery, making sure that it's placed with the negative side facing downwards. After you've inserted the circuit board, put it back together and try again.

If this doesn't solve the issue, you could have a more serious issue. In this instance, you should call your dealer or a repair shop that specializes in your car's make. They can determine the problem by using a radio-frequency tester which is a device that can determine if your key fob transmits signals to the computer in your car.
