Car Key Button Repair
The buttons on car keys are subject to a lot of pressure and are especially vulnerable if used frequently. Over time, they can be damaged.
There are a few easy fixes that can get your keys working again. However, these techniques carry 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
It's possible to change the battery if your key fob no longer works as it should. You can purchase replacement batteries in any drugstore chain nationwide or in the parts department of your local car dealership. Some manufacturers will even include an extra key fob battery in the packaging when you purchase a car from them.
First, you'll need to find out what type of battery is used in your key fob. The manufacturer should have this information on their website or you can look it up on the key fob itself. Generally speaking, the most popular battery that is used in key fobs is a button cell type, similar to those used in remote controls and watches. These kinds of batteries are available at stores like Walgreens and Energizer, and are available for purchase for under $5 for a package of two.
Once you know what kind of battery your key fob uses then you can remove it and take out the old battery. It is possible to open most key fobs using your fingers or a flat tool such as a screwdriver, at the seam or notch at which they connect. After the key fob has been opened the battery will be released. Then, you can replace it in the same orientation. Many key fobs are powered by CR2032 batteries. These batteries can be found at retailers that sell AAA or AA batteries.
You can snap the two halves back together after you have inserted the new battery and then test the key fob to ensure that all buttons function properly. Pressing the locks and unlock buttons on the key fob while it is pointed at your vehicle will help you determine whether or not everything is working as it should be. If G28 Car Keys is not responding to the key fob, it could be required to reprogram the key fob to establish an electronic connection between the two. This is a relatively simple process that only requires a phone or other device.
Reprogram the Key Fob
If your key fob does not work and you believe it's time to replace it the fact is that it might not require an entirely new battery, but rather the old one has to be changed. This procedure is different for each car. To find out how to go about it you must consult the owner's manual. It's usually available in PDF format on the automaker website. You can also search YouTube for videos.
In the majority of modern vehicles, a special procedure is required to put the vehicle into 'programming mode'. This typically involves pressing the power button a few times on the door of the driver or ignition, while simultaneously pressing a button on a fob within a specific time frame. This is how the fob transmits its digital identification code to the vehicle, and it stores it in the memory. The fob will work like an ordinary key once it is programmed.
Reprogramming a fob will erase any previous keyfobs. Therefore, if you wish 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, major retailers, or even online. But, it is important to be aware of the model and make of your car prior to buying a fob battery as the right kind isn't always easy to locate.
A CR editor stumbled across the battery for her key fob however, it was from an entirely different vehicle. This meant that she could start her car and unlock the door, but she couldn't lower the windows.
Dealers can be of great assistance in this regard, since they have the equipment necessary to reprogram the fob for the specific vehicle. Dealers are required to carry out this service on certain European vehicles like Audi and BMW because they have specialized security features which can only be reset at the factory. Other dealers we spoke with like those from Toyota and Lexus, were willing to attempt reprogramming an original fob so they knew the exact make and model of the vehicle you are driving.
Replace the Button
If you've tried changing the battery, reprogramming your key fob and you're still unable to start your car, it might be time to replace that button on your key. The button on the car key is subject to a lot of use and jostling, and it can be damaged or stuck over time. Every time you press the button on your key fob the unique code is sent out in a sequence which the receiver in the vehicle can recognize. When you try to operate your car from a distance without using the proper code could cause it not to recognise you and then lock the doors or turn off the engine.
You can buy replacement buttons online or in many local hardware stores. They are relatively simple to install and open and require only a small amount of clear plastic tape to cover the button.
Contact an Auto Locksmith
If you're experiencing a problem with your car key button it could be time to consult the experts. Auto locksmiths are experts in the repair of electronic keys and locks. These experts have the tools and expertise to identify and fix issues with your key fob. This includes replacing batteries and reprogramming them. They have the knowledge and skills to handle more complicated tasks, such as fixing a damaged key or cutting an alternative key.
One of the most frequent reasons for a car's key button to stop working is because the switch inside it has worn out. This is due to excessive use and exposure to elements. The switch is made of an extremely hard plastic with multiple switches on its surface. Each of these switches is responsible for activating a specific function that you use the key for. As the switch ages over time, it becomes harder to activate each of these functions. You will have to exert more pressure on the switch in order to activate it. This can further damage the switch and decrease its lifespan.
The most effective solution to this issue is to replace the battery inside your car key fob. The majority of cars have lithium-ion coin or button batteries that you can find at pharmacies, supermarkets and home improvement stores. After replacing the battery your key fob should work once more.
If the issue persists, it could be because your key fob's contacts have been worn out. The contacts are rubber-like and coated with an electricity conducting film, which can wear away over time. They are exposed to elements while you use the key, so they're constantly being exposed to moisture and dirt. They'll eventually wear down to the point that they're unable to contact with the circuit board, or the sensor underneath the keypad.
The dealership can replace your key fob, but it could be costly and takes a lot of time. Another option is to contact a local car locksmith who can repair your key fob and save you money.
