Car Key Button Repair
The buttons on keys for cars are subject to a lot of pressure, especially if they are used frequently. This can result in them becoming faulty over time.
Fortunately, there are several quick fixes to make your keys work again. These methods do not come without risk however. Altering batteries or altering your key fob's security can be dangerous. If you're not comfortable with these methods, it's recommended that you consult with a professional auto-locksmith.
Change the Battery
It could be time to replace the battery if your key fob doesn't function as it should. You can usually buy replacement batteries at any national chain drug store or in the parts department of your car dealership. Some manufacturers will even include an extra key fob battery in their packaging when you purchase a car from them.
The first thing you'll need to determine what battery is used in your key fob. The manufacturer should have this information on their website or you can look it up on the actual key fob. Generally, the most common battery that is used in key fobs is a button cell type that is similar to the ones used in watches and remote controls. These batteries are available at Walgreens, Energizer and other stores for less than $5 per box of two.
If you are aware of the type of battery your key fob has, you can remove it and take out the old battery. Most key fobs are constructed with a notch or a seam between them, which you can open by using your fingers, or by using a flat tool like a screwdriver. Once the key fob has been opened, the battery will come out. Then, you can replace it in the same orientation. A lot of key fobs are powered by CR2032 batteries. These batteries are sold at stores that sell AAA or AA batteries.
You can snap the two halves back together after inserting the new battery and test the key fob to ensure that all buttons are functioning properly. You can verify that all functions are working correctly by pressing the lock and unlock button on the key fob, while pointing it at your vehicle. If your vehicle isn't responding to the keyfob, you may have to reset the fob to establish a wireless connection. This is a fairly simple process that only requires your phone or a different device.
Reprogram the 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 old one has to be reset. This process varies by car, so your best bet is to consult the owner's manual (usually available in PDF form on the automaker's website) or look on YouTube for videos explaining how to accomplish this.
Most modern vehicles require a special procedure to put the vehicle into 'programming mode,' which is usually done by pressing the power button on the driver's side door or ignition several times while pressing the fob's button within a specified time. This is how the fob sends its digital identification code to the vehicle, which stores it in its memory. The fob will work like normal keys once it is programmed.
Reprogramming a keyfob will erase any previous keyfobs. Therefore, if you wish to keep other fobs, they must be carefully and swiftly reprogrammed after the first one.
There are a few replacement batteries for a car key fob at hardware stores, big-box retailers, or even online. You will need to know your car's model and make before you purchase a fob as it isn't easy to locate the right battery.
A CR editor once came across an appropriate battery for the key fob she had, but it was for a different model of car. This meant that while she could start the car and open the doors, she wasn't capable of lowering the windows.
Luckily, dealers can assist you in this instance and most dealers have the equipment needed to reprogram a fob for the specific vehicle. Some European automobiles, like those manufactured by Audi and BMW generally require you to go to a dealer to get this service due to the fact that they have specific security features that can only be reset by the manufacturer. Other dealers we spoke with, including those from Toyota and Lexus were willing to try reprogramming the fob in a replacement as they knew the exact model and make of the car you own.
Replace the Button
If you've tried changing the battery and reprogramming the key fob and still not being able to start your car, it could 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 become stuck or damaged over time. Each time you press the button on your key fob, the unique code is sent in a pattern that the vehicle's receiver can recognize. If you attempt to operate your vehicle from some distance, it might not recognise you. It might close the doors or turn off the engine.
You can purchase replacement buttons online or at many local hardware stores. They are easy to install and open and require only a small amount of clear plastic tape to cover the button.

In the end, you will need to press down harder on the switch in order to enable it to function. This can result in more damage to the switch, further reducing its life span.
