Most of the time, these issues are simple to fix. You can reset it by following the steps in the owner's manual.

Check the Battery

The remote control is powered by the battery in a key fob. It's a tiny and affordable part that should be replaced frequently to ensure the fob's functionality. But, aside from the battery, there are other reasons your fob may not be working. These issues could include physical damage, water exposure, or internal component failure. Whatever the cause when your key fob isn't responding it's time to replace the battery.

First, make sure you have the correct size battery. Most modern key fobs are powered by a three-volt CR2032 which is easily found in a wide range of stores. The majority of these batteries are stamped with the size on one of the edges of the fob. A quick search for the name of your car's brand will help you identify the exact type of battery it takes.

The fob must be opened carefully and remove the current battery. Take a picture of the inside of the fob to ensure you put it back in the correct way. This simple action can help you avoid needing to purchase a new fob because you made an error when making it.

Some key fobs also have a mechanical backup key known as an emergency blade. The key blade is situated inside the key fob, and it allows you to unlock the door of the driver's seat of your car in the event that the remote control fails. In order to access the key blade, you need to locate the notch in the center of your fob. The notch is typically an oval shape that is hidden by the fob's plastic casing.

If you want to check the battery voltage with extra caution, you can make use of a multimeter. Most modern key fobs have a voltmeter built into their casings, but you can also get a multimeter for a few dollars from most hardware stores. Generally, the battery should be reading 3.0 volts or higher. If it is below that level, it could indicate a battery in its last stages and should be replaced immediately.

Check the Buttons

It's not uncommon for remotes to cease working after a while, especially when the vehicle is frequently used or if there is lots of physical abuse involving it. Fortunately, a majority of the times, it's simple to identify and repair a problem with the remote key fob and changing the battery is usually all that's needed.

Modern car key fobs include numerous buttons that serve different functions. For example, they can lock and unlock the doors as well as activate the panic button, and even open the trunk. When a button on the fob is hit, it transmits a radio code to a receiver inside the vehicle. Some fobs also have a button that can start the engine, which can be especially handy during cold winter mornings or hot summer days.

The buttons on a key fob are reset by taking it apart and checking that they're not broken or stuck. Key fobs aren't designed to be disassembled however, the battery connectors on a key fob may become loose over time. Soldering is a method to reconnect the button contacts to the circuit board if they've been disconnected. This will bring back the fob's functionality.

In addition, if the fob has been damaged or dropped in some other way, the buttons could be broken or displaced from their alignment or misaligned in any way. These types of issues are generally more difficult to repair on your own but can usually be addressed by a local auto shop with the right equipment and experience.

Keep an extra key fob in an area that is secure, just in case the one you use most often stops working. You can avoid being stranded in the in the middle of nowhere with no keys, or having to pay an enormous amount to have the vehicle transported to the dealer. Check your car insurance, car club membership, or extended warranty coverage to determine the cost of replacing the key fob.

Check the Casing

Don't disassemble the circuit board or antennas. These have electric current running through them that keep the key fob programmed to your vehicle, and when you break the circuits, you'll have to go to a dealer or choose an Interstate All Battery Center location to re-program it.

After you have replaced and removed the battery, it's a good idea for you to dry the key fob by placing it into a plastic bag containing silica gel packets. This will help prevent future moisture issues and help the battery last longer.
