Car Key Button Repair

The buttons on keys for cars are exposed to a lot and are especially vulnerable if used frequently. As time passes, they may become damaged.

There are a few easy fixes that will allow your keys back to working. However, these solutions come with risks when it comes to changing batteries or altering the key fob. If you are not comfortable with these methods, it's best to consult a professional auto-locksmith.

Change the Battery

If you are noticing that your key fob is not working as it should, it may be time to replace the battery. You can typically purchase replacement batteries at any national chain drug store or the parts department of your car dealership. Some manufacturers offer a spare battery with your car when you buy it.


The first thing you will need to do is find out which battery is used in your key fob. This information is typically available on the website of the manufacturer or by checking the key fob. Generally, the most common battery used in a key fob is a button cell type that is similar to the ones used in watches and remote controls. These kinds of batteries are found at stores such as Walgreens and Energizer, and can be bought at less than $5 for a package of two.

Once you know what kind of battery your key fob is using then you can open it and remove the old battery. You can open most key fobs using your fingers or a flat tool, such as a screwdriver, at the seam or notch at which they join. After the key fob has been opened the battery will be released. Then, you can replace it with the same orientation. The majority of key fobs utilize CR2032 3V batteries, which are easily available at many stores that sell AAA and AA batteries.

You can snap the two halves back together after inserting the new battery and then test the key fob to confirm that all buttons are functioning properly. Pressing the locks and unlock buttons on the key fob while pointing it towards your vehicle will allow you to determine whether or not everything is functioning in the way it should. If your car isn't responding to the fob, you might need to reprogram the fob and establish an internet connection. It's an easy procedure and requires only the use of your smartphone or another device to accomplish this.

Reprogram your key fob

If your key fob won't function and you believe it's time to replace it, it may not need the replacement of a battery, but instead the original one must be reprogrammed. This procedure is different for every car, so your best bet is to refer to the owner's manual (usually available in PDF format on the site of the automaker) or look on YouTube for videos explaining how to go about this.

In the majority of modern vehicles, a particular procedure is required to put the vehicle in 'programming mode'. This typically involves pressing the power button multiple times on the driver's door or ignition, while simultaneously pressing the button on the fob within a time-specific period. This is how the fob transmits its digital identity code to the car, which saves it in memory. The fob can function as normal keys once it is programmed.

Reprogramming a fob will erase any previous keyfobs. Therefore, if you want to keep other fobs, they should be carefully and quickly reprogrammed following the initial one.

Sometimes you can find replacement batteries for car key fobs at hardware stores, large retailers, or even on the internet. But, it is important to be aware of the make and model of your car before purchasing a battery for your fob because the right type can be difficult to locate.

A CR editor once found an appropriate battery for the key fob she used, but it was for a different model of car. This meant that while she could start the car and open the doors, she was not able to lower the windows.

Fortunately, the dealer can assist you in this instance and most dealers have the equipment needed to reprogram a fob into specific cars. Some European vehicles, such as the ones manufactured by Audi and BMW, will usually require a dealer for this service because they use special security features that can only be reset by the manufacturer. Certain dealers, like those at Toyota and Lexus were willing to reprogramme a replacement key fob in the event that you could identify the exact model and brand of your vehicle.

Replace the Button

If you've tried changing the battery, or reprogramming your key fob, but you're still unable to start your car, it might be time to replace that button on your key. The key on your car receives many uses and jerking over time and can get stuck or even broken. Each time you press the button on your key fob, an individual code is transmitted in a sequence that the receiver in the vehicle is able to recognize. If you attempt to operate your car from a distance and not using the proper code could cause it to not recognize you and shut the doors or shut off the engine.

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