Car Key Button Repair
Car key buttons undergo many abuses, especially if used frequently. This could lead to them becoming faulty over time.
There are a few quick fixes that can get your keys back in working order. These solutions are not without risk however. Making changes to batteries or tampering with your key fob's security can be dangerous. If you're not comfortable with these methods, it's best to consult 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 typically purchase replacement batteries from any chain drug store, or the parts department at your car dealership. Some manufacturers include an extra battery with the car when you purchase it.
The first thing you will need to find out which battery your key fob is powered by. The manufacturer should have this information on their website, or you can check the key fob itself. The most common type of battery found in the keyfob is the button cell like the ones found in remotes and watches. These batteries are available at Walgreens, Energizer and other stores for less than $5 per box of two.
If G28 Car Keys are aware of the type of battery your key fob is using, 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, such as a screwdriver, at the notch or seam where they connect. When the fob is opened, the battery will pop right out and you can then put in the new one in the same direction as the old one. Many key fobs are powered by CR2032 batteries. These batteries are sold at stores that sell AAA or AA batteries.
After the new battery has been inserted, you can take the two parts of the key fob back together and check that all buttons are functioning properly. Pressing the lock and unlock buttons on the key fob while it is pointed at your vehicle will allow you to determine if everything is functioning in the way it should. If your car isn't responding to the keyfob, you may require reprogramming the fob to establish an internet connection. This is a relatively easy process that requires your phone or a different device.
Reprogram the Key Fob
If your key fob does not work and you think it needs to be replaced the fact is that it might not require a new battery, but instead the original one must be reset. This process is different for every car. To learn how to go about it, consult your owner's manual. It's typically available in PDF format on the website of the automaker. You can also search YouTube for videos.
In the majority of modern vehicles, a specific procedure is required to put the vehicle into 'programming mode'. This usually involves pressing the power button a few times on the driver's door or ignition, while simultaneously pressing the button on a fob within a time-specific period. The fob transmits its digital identification code to the vehicle, and then saves it. After the fob is programmed, it can perform the same way as a normal key.
It is important to remember that the process of reprogramming a key fob can erase any other key fobs that have been programmed previously. If you wish to keep the other fobs following the first, they must be reprogrammed quickly and with care.
Sometimes, you can find replacement batteries for key fobs for cars at hardware stores, major retailers, or even online. It is important to know your car's make and model before you purchase a key fob since it can be difficult to locate the right battery.
A CR editor found a battery that was compatible with the key fob she used however it was for a different 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 in this case and most dealers have the necessary equipment to reprogram a fob for specific cars. Dealers are required to perform this service on some European vehicles like Audi and BMW because they have specialized security features which can only be reset at the factory. Other dealers we spoke to like those at Toyota and Lexus, were willing to attempt reprogramming a replacement fob as long as you knew the exact make and model of the car you own.
Replace the Button
If you've tried changing the battery, reprogramming your key fob, and still can't start your car it might be time to replace the button on the key. The key on your car receives a lot of use and jostling over the years and may become stuck or broken. Every time you press the button on your key fob, the unique code is transmitted in a sequence which the receiver in the vehicle is able to recognize. When you try to operate your vehicle from a distance without the proper code could cause it to not be able to recognize you and then lock the doors or turn off the engine.
