Car Key Repair - How to Fix a Dead Remote
Car remotes provide a excellent convenience for drivers. They can unlock doors, open trunks, and even start the car. However, they can stop working at inconvenient times.
Before you go to the dealer, consider some quick solutions when your key fob stops functioning. These steps could save you money.
Keyless Entry System
Instead of having to fiddle around with keys in your purse or pocket instead, walk to your car, press a button on the key fob, and then open the doors and start the engine. It's a simple function that makes driving a car more enjoyable and safe. The keyless entry system, as any other device, may be damaged by repeated use or by other factors. If you're having problems with your system, you can either visit the dealer or phone a locksmith.
Keyless entry systems work by sending radio signals, and then searching for the response signal from a key fob. If the system can recognize the signal, it will trigger to open the doors of the vehicle and activate the computer onboard. Certain systems have another receiver mounted on the trunk of the car, which opens it automatically when you put your foot underneath it.
Each key fob is given an individual digital identification number by the manufacturer. A proprietary technical process called "programming" is used to configure the fob to work with the specific car's system. This typically involves turning the ignition of the car repeatedly in a specific sequence and may also require pulling or pushing different buttons and levers, or taking out fuses.
When a key fob is programmed to your specific car's keyless entry system it transmits the digital identity code as well as a function code that instructs the car what to do (lock or unlock the trunk or open the trunk). The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. The computer in the car will allow the vehicle to be opened and start the engine if it's authorized.
A clever criminal could intercept and use the code transmitted between the keyfob and vehicle. This requires a device that records the transmission, and then retransmits it later in the event that the system doesn't want it. To help combat this issue, the majority of keyless entry systems use rolling code, which ensures that each new signal from the transmitter received by the car has a different counter than the previous one.
Batteries
The most frequent cause of the car remote key fob not working is an inoperative battery. If you have an extra key fob it's a simple and inexpensive fix. Fortunately, the majority of fobs have standard watch-style batteries that are sold at hardware stores or big-box retailers for $10 or less. You can find instructions to disassemble your key fob on the internet or in your vehicle's manual.
Be cautious not to damage any of the circuits or antennas within the case after you've removed the battery. They're likely to be holding the key fob's program to your particular car and any disruption to them will render it unprogrammable (and likely to fail). If you must move them, do it slowly because some key fobs have fasteners that are able to open and scatter key fob pieces all over your living room.
The majority of key fobs have a single hole for the screwdriver or another pry tool to open the case. However, it's a good idea use your tool to wedge it around the outside of the case first, as if you were peeling an apple or orange. Be careful not to apply too much pressure, as the case of the fob is usually made of plastic and may crack or break if you apply too much pressure to it.
If you're ready to replace the battery, make sure to match its size and type to your key fob. Some key fobs come with two batteries while others need one. A bad battery could render your remote keyfob useless.
After the new battery is in place, try using your key fob again to see if the battery has fixed your problem. If car key immobiliser repair doesn't work, you will need to determine whether your fob is suffering from an issue that is more complicated and requires professional diagnosis. You may need to have the fob reprogrammed at the dealer or purchase a new one.
Buttons
The buttons on your key fob might be small, but they are packed with electronics. It's not a surprise that they'll fail from time-to-time. If the car key button suddenly stops working, you'll be able to usually fix it yourself.
One of the most frequent reasons that a car key remote fails to function is that dirt or crud has accumulated between the buttons. To clear this up take care to remove both batteries and scrub each button using a cotton swab that has been dipped in alcohol rubbing. Make sure you dry the buttons completely before reinstalling them.
It's possible that the key fob was damaged in some way, possibly dropped on concrete or accidentally scratched by a sharp object. If this is the case, you can test your key fob's functionality by using another one.
The door lock sensor might have been unable to function in your vehicle. The sensor is a tiny metal component attached to the key fob's door lock button. It's not unusual for it to break due to weather conditions or extended use. To activate the sensor again just press your key button a few times without locking or unlocking your doors to reset it.
If all else fails you can always test the function of a spare key by unlocking and locking your doors using it. If the spare key doesn't work, it may be necessary to find a 24-hour locksmith that offers car key repair to get your remote working again.
If your car's key fob is working but still not locking or unlocking your vehicle, try to re-programme your computer system. If you have had the same key fob for a time, it may need to be reset every few months in order to continue to work with your vehicle. It's not the ideal situation however it's much better than having to replace your remote entirely.
