Car Key Button Repair
The buttons on car keys are subjected to a lot, especially if they are often used. This can result in them becoming faulty over time.
There are a few easy fixes that can get your keys working again. However, these methods have risks associated with changing batteries or tampering with your key fob. If you are not comfortable with these methods, it is recommended that you consult with an expert auto-locksmith.
Change the Battery
It may be time to replace the battery in the case that your key fob isn't working as it should. You can buy replacement batteries at any national chain drugstore or in the parts department at your local dealership for cars. Some manufacturers will even include a spare key fob battery in the packaging when you purchase a car from them.
First, you'll need to find out what kind of battery is used in your key fob. This information is usually available on the site of the manufacturer or by looking at the key fob. The most popular kind of battery that is found in a keyfob is the button cell that is like the ones found in watches and remotes. These batteries are available at Walgreens, Energizer and other stores for less than $5 per pack of two.
You can remove the old battery from your key fob when you know which type of battery it is using. It is possible to open most key fobs using your fingers or a flat tool, such as a screwdriver, at the notch or seam where they connect. After the fob has been opened, the battery should be able to pop out and you can then put in the new one in the same direction as the old one. A lot of key fobs are powered by CR2032 batteries. These batteries are sold at stores that sell AAA or AA batteries.
You can join the two halves together after you have inserted the new battery and test the key fob to confirm that all buttons function properly. You can determine if all functions are working correctly by pressing the lock and unlock buttons on the key fob while pointing it towards your vehicle. If your car does not respond to the keyfob, you may require reprogramming the fob and establish an internet connection. Fortunately, this is quite simple and requires only the use of a smartphone or another device to accomplish this.
Reprogram your key fob
If you're having trouble with your key fob and think it needs a new one It may not be necessary to replace it. Instead, the old battery may need to be reprogrammed. This procedure varies for each vehicle so the best way to find out is to consult the owner's manual (usually available in PDF format on the website of the automaker) or look on YouTube for videos explaining how to accomplish this.
In the majority of modern vehicles, a specific procedure is required to put the vehicle into "programming mode". This typically involves pressing the power button several 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 identification code to the car, which saves it in its memory. Once the fob is programmed, it can behave as an ordinary key.
It is important to remember that the process of reprogramming a key fob can erase any other key fobs that had been previously programmed. Therefore, if you want to keep other fobs, they need to be carefully and quickly reprogrammed following the initial one.
You can sometimes find replacement batteries for a car key fob at hardware stores, big-box retailers or online. However, you must be aware of the make and model of your vehicle prior to buying a fob battery as the correct type of battery can be difficult to locate.
A CR editor once found a battery that was compatible with the key fob she owned, but it was for a different vehicle. Full Review meant that she could start her car and unlock the door, but couldn't lower the windows.
Dealers can be extremely helpful in this regard, since they have the equipment necessary to reprogram the fob for specific vehicles. Certain European automobiles, like the ones manufactured by Audi and BMW typically require a dealer for this service because they use specific security features that can only be reset by the manufacturer. Some dealers, like those at Toyota and Lexus were willing to reprogramme the key fob in a replacement in the event that you could identify the exact model and make of the car you own.
Replace the Button
If you have tried changing the battery and programming the key fob, but you still cannot start your car, it may be time to replace the button on your key. The key on your car receives a lot of use and jerking over time and can get stuck or even broken. Each time you press the button on your key fob a unique code is sent in a sequence that the receiver in the vehicle can recognize. If you attempt to operate your vehicle from a distance without the correct code can cause it not to recognise you and shut the doors or turn off the engine.
You can purchase replacement buttons online or in several local hardware stores. They are relatively simple to open and install and require just a bit of clear plastic tape to cover the old button.
