Car Key Button Repair
The buttons on keys for cars are exposed to a lot particularly if they are used frequently. As time passes, they may become damaged.
Fortunately, there are several quick fixes to get your keys back to working. These methods do not come completely safe, however. Altering batteries or altering your key fob's security can be risky. If you're not comfortable performing these yourself, it is recommended to consult an auto locksmith professional.
Change the Battery
If you are noticing that your key fob no longer working as it should, it could be time to replace the battery. You can buy replacement batteries at any national chain drugstore or in the parts department at your local car dealership. Some manufacturers even include an extra key fob battery in the packaging when you purchase your vehicle from them.
It is first necessary to find out what kind of battery is used in your key fob. This information is typically available on the site of the manufacturer or by examining the key fob. Generally speaking, the most popular battery that is used in key fobs is a button cell, similar to those used in remote controls and watches. These types of batteries are typically found at stores such as Walgreens and Energizer, and can be bought at less than $5 for a package of two.
If you are aware of the type of battery your key fob has then you can open it up and take out the old battery. It is possible to open most key fobs by using your fingers or a flat tool, like a screwdriver, at the seam or notch at which they connect. When the fob is opened, the battery should be able to pop out and you can insert the new one in the same orientation as the previous one. Most key fobs use CR2032 3V batteries, which are easily available at many retailers that sell AAA and AA batteries.
After the new battery has been inserted, you can snap the two halves of the key fob together and test it to make sure that all buttons function properly. You can verify that everything is working properly by pressing the lock and unlock buttons on the key fob, while pointing it towards your vehicle. If your vehicle is still not responding to the key fob, it might be necessary to reprogram the key fob and establish an internet connection between the two. It's an easy procedure and requires only the use of your smartphone or another device to perform the procedure.
Reprogram the Key Fob
If you're having issues with your key fob and believe it needs a new one however, it may not be required to replace it. Instead the old battery might require reprogramming. This procedure is different for every car. To find out how to do it, consult your owner's manual. It's usually available in PDF format on the automaker's website. You can also search YouTube for videos.
In 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 a button on a fob in the time frame specified. This is how the fob communicates its digital identity code to the car, which saves it in the memory. The fob will work like an ordinary key once it has been programmed.
Reprogramming a keyfob will erase any previous keyfobs. Therefore, if you'd like to keep other fobs, they must be carefully and quickly reprogrammed after the first one.
Sometimes you can find replacement batteries for key fobs for cars at hardware stores, major retailers, or even online. However, you must be aware of the model and make of your car prior to buying a fob battery as the correct type of battery isn't always easy to locate.
A CR editor found 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 was not able to lower the windows.
Dealers can be of great assistance in this situation, since they have the equipment necessary to reprogram the fob on a specific vehicle. Some European cars, such as those made by Audi and BMW, will usually require a dealer for this service because they use specialized security features that can only be reset by the manufacturer. Some dealers, such as those at Toyota and Lexus were willing to reprogram a replacement key fob if you knew the exact model and make of the car you own.
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 could be time to replace the button on your key. Your car key button receives lots of use and jostling over the years and can sometimes become stuck or broken. Every time you press the button on your key fob, a unique code is sent out in a sequence which the receiver in the vehicle is able to recognize. If you try to operate your vehicle from a distance, it may not recognize you. It may lock the doors or shut off the engine.
You can buy replacement buttons online or at several local hardware stores. They are easy to open and install and require just a bit of clear plastic tape to cover the old button.

One of the most common reasons for a car's key button to stop working is because the switch inside has worn out. The use of the switch and exposure to elements are the main reasons. The switch is typically made of a tough plastic material and has a variety of switches on its surface. Each switch is able to activate the function for which you are using the key. As the switch age, it becomes more difficult to activate these functions. You will have to exert more pressure on the switch in order to make it work. This could further damage the switch and reduce its lifespan.
