Car Key Repair - How to Fix a Dead Remote
Car remotes offer excellent convenience for drivers. They allow you to unlock doors, gain access to trunks and even start the engine. These remotes are prone to malfunction at the most inconvenient moments.
If you notice that your key fob is not working, try a few quick fixes before going to the dealer. These steps could save you money.
Keyless Entry System
You don't have to look for keys in your purse or pockets. Just walk up to your car, push the button on the keyfob and the doors will be opened and the engine will begin. It's an easy feature that makes driving a car more relaxing and secure. However, just like any other device that has a keyless entry system, the keyless entry system may fail due to frequent use or due to other factors. If you are having issues with your system, you can either go to the dealer or contact a locksmith.
The way a keyless entry system functions is by sending radio signals and then looking for a response signal from the key fob. If the system is able to recognize the signal, it's triggered to open the doors of the vehicle and activate the onboard computer. Certain systems have another transmitter located in the trunk of the car which opens it when you waggle your foot beneath it.
Each key fob is given a unique digital identification code by the manufacturer. A unique process of technology known as "programming" is used to configure the fob to work with the specific car's system. This usually involves turning the ignition of the vehicle several times in a certain sequence, and could include pulling or pushing different buttons and levers, or removing fuse.
Once the key fob has been programmed into your car's keyless system it transmits a digital identity code as well as a function-code to instruct the car to (lock, unlock or open the trunk). The receiver in the car verifies that the transmitter is the person it claims to be by using an authentication and encryption procedure. The onboard computer will unlock the vehicle and start the engine if it is authorized.
A skilled criminal could snoop and use the code sent between the keyfob and the vehicle. This would require a special device to record the transmission then retransmit it later when the system isn't expecting it. Most keyless entry systems utilize rolling codes to combat this. This ensures that each new signal from a transmitter received by a car has a counter value that is different from the previous one.
Batteries
A dead battery is the most frequent reason for car remotes not to function. It's an easy and cheap fix if you have a spare key fob on your desk to replace the old one with. The majority of fobs are powered by watch-style batteries that can be purchased at big-box stores or hardware stores for less than $10. You can find instructions to disassemble your key fob by searching the internet or in your car's manual.
Once key repairs 've removed the battery, be careful not to damage any of the circuits or antennas in the case. They're likely to hold the key fob's programming to your particular car and any disruption to them will make it unprogrammable (and probably not work). If you need to move key fobs, take care. Certain key fobs might come with fasteners that are able to be removed and scatter key fob pieces all over your living space.
The case of a majority of key fobs is equipped with a single screwdriver hole. To open it, use a tool to pry it open. To begin you must push the tool along the outside edge of the case like you would peel an apple or orange. Do not apply too much pressure, as the case of the key fob is typically constructed of plastic and could crack or break if you apply too much force to it.
Make sure you match the size and type of the battery to your key fob when replacing it. Some key fobs come with two batteries while others only need one. The wrong battery could make your remote key fob useless.
If the issue persists, you can try again with your key fob after installing the new battery. If it doesn't it, you'll have to determine whether your key fob is suffering from an issue that is more complex and requires a professional diagnosis and repair. You may have to have the key fob reprogrammed by a dealer or buy an entirely new one.
Buttons
The buttons on your key fob may appear small however they're packed with electronics. It's not surprising that they will fail from time-to-time. If the car key button suddenly stops working, you can usually fix it yourself.
The most common reason a car remote key stops working is because dirt or crud has gotten stuck between the buttons. To clear this up take care to remove both batteries and clean each button with a cotton swab dipped in alcohol rubbing. Be sure to dry them thoroughly prior to installing the batteries.
It's possible that your key fob was damaged in some way, such as being dropped on concrete or accidentally scratched. If this is the case, you can test the function of your key fob using another one.
The door lock sensor might have stopped working in your vehicle. This is a tiny metal piece that is attached to the door lock button on your key fob, and it's not common for this sensor to break after long-term usage or exposure to harsh weather conditions. To reset the sensor, simply try pressing your key fob a few times without locking or unlocking your doors to reset it.
If all else fails, you can test the functionality of a spare key by trying to unlock and lock your doors using it. If the spare key does not work, you may have to contact a locksmith on call 24 hours a day who provides repair of car keys to get your remote working again.
You can change the settings on your computer if your car key button works, but it still doesn't lock or unlock the vehicle. If you've used the same key fob a time, it might need to be reset every couple of months to to work with your vehicle. It's not optimal, but it's better than buying a new remote.
