The buttons on car keys are subject to a lot of pressure particularly if they are used frequently. This can result in them becoming faulty over time.

There are a few easy fixes that can get your keys working again. However, these methods have risks when it comes to changing batteries or tampering with the key fob. If you're not comfortable with these methods, it's recommended to seek advice from a professional auto-locksmith.

Change the Battery

If you are noticing that your key fob not functioning as it should, it might be time to replace the battery. You can usually buy replacement batteries at any national chain drug store, or the parts department at your car dealership. Some manufacturers will even include a spare key fob battery inside the packaging when you purchase a car from them.

The first thing you'll need to find out which battery your key fob uses. The manufacturer should have this information on their website or on the key fob itself. Generally, the most common battery that is used in a key fob is a button cell type similar to the ones used in watches and remote controls. These kinds of batteries are typically found at stores such as Walgreens and Energizer, and can be bought at less than $5 for a set of two.

If you are aware of the type of battery your key fob uses then you can open it and take out the old battery. Most key fobs are designed with a notch or a seam between them which you can either open with your fingers, or with the flat side of a screwdriver. Once the fob is opened, the battery should come out, and you can insert the new one in the same direction as the previous one. Most key fobs use CR2032 3V batteries, which are readily accessible at a variety of retailers that sell AAA and AA batteries.

After the new battery has been inserted After that, you can connect the two halves of the key fob back together and check that all buttons work properly. Pressing the lock and unlock buttons on the key fob while pointing it at your vehicle will allow you to determine if everything is functioning as it should be. If your vehicle is still not responding to the key fob, it could be necessary to reprogram the key fob and establish an internet connection between the two. This is a fairly easy process that requires your phone or a different device.

Reprogram the Key Fob

If your key fob does not function and you believe it needs to be replaced the fact is that it might not require a new battery, but instead the old one needs to be reset. This procedure is different for every car so the best way to find out is to refer to the owner's manual (usually available in PDF format on the automaker's website) or look on YouTube for videos on how to accomplish this.

Modern vehicles require a special procedure to put the vehicle in 'programming mode,' which is usually done by pressing the power button on the driver's side door or ignition several times while pressing a button on the fob within a specified time. This is how the fob sends its digital identity code to the vehicle, and it stores it in its memory. After the fob is programmed, it will function like a normal key.

It's important to note that reprogramming a key fob will wipe out any other key fobs which have been previously programmed. Therefore, if you'd like to keep other fobs, they need to be carefully and quickly reprogrammed after the first one.

You can sometimes find replacement batteries for your car key fob at hardware stores, big-box retailers, or even online. But, it is important to know the make and model of your vehicle prior to purchasing a fob battery because the right type can be tricky to find.

A CR editor once came across an appropriate battery for the key fob she used, but it was for a different car. This meant that while she was able to start the car and unlock the doors, she wasn't capable of lowering the windows.

Fortunately, the dealer can assist you in this instance, as most of them have the tools needed to reprogram a fob into the specific vehicle. Certain European cars, such as those manufactured by Audi and BMW typically require you to go to a dealer for this service since they utilize specific security features that can only be reset by the manufacturer. Other dealers we spoke to, including those at Toyota and Lexus were willing to reprogramme a replacement fob as they knew the exact model and make of the car you own.

Replace the Button

If you've tried changing the battery and programming the key fob and still cannot start your car, it may be time to replace the button on the key. The button on your car key is subjected to a lot of use and jostling and can be damaged or stuck over time. Each press of the button on your key fob generates a unique code that is recognized by the receiver inside the vehicle. If you attempt to operate your vehicle from some distance, it might not recognize you. It may close the doors or turn off the engine.

You can purchase replacement buttons online or at several local hardware stores. It is easy to install them and they are very easy to open.

Contact an Auto Locksmith

The switch on the car key button is often worn out. This is due to overuse and exposure to elements. The switch is typically constructed from a hard plastic material and has many different switches on the surface. Each switch activates the function for which you are using the key. As the switch wears out over time, it becomes harder to turn on each of these functions. You will need to exert more pressure on the switch to get it to work. This could cause further damage to the switch and reduce the life span of the switch.

The easiest way to solve this problem is to replace the battery in your car key fob. You can find lithium-ion button or coin cell batteries in pharmacies, supermarkets and home improvement stores. After you've replaced the battery, your key fob should be working again.

The contacts are made of rubber and coated with an electricity conducting film, which could wear away over time. When you use the keypad, they are exposed to dust and moisture. Eventually, they will wear down to the point that they no longer make contact with the circuit board or the sensor beneath the keypad.

You can try to have the key fob replaced by visiting a vehicle dealership, but this can be expensive and could take quite a while. The other option is to contact a local car locksmith who will be able to fix your key fob and help you save money.
