Car Key Repair - How to Fix a Dead Remote
Car remotes offer excellent convenience for drivers. vehicle key repairs can unlock doors, open trunks, and even start the car. However, they can stop working at inconvenient times.
If you notice that your key fob not working, you can try a few fixes before going to the dealership. These suggestions could save you money.
Keyless Entry System
You don't need to search for keys in your purse or pockets. Just walk up to your car, press the button on the keyfob, and the doors will be opened and the engine will begin. It's a convenient feature that has made the experience of car driving more enjoyable and safer. The keyless entry system, like any other device, may be damaged by repeated use or other elements. If you've experienced problems with yours, you have two options: Visit the dealership or call a local locksmith.
A keyless entry system operates by sending radio signals and then scouring for a response signal from the key fob. If the system is able to recognize the signal, the car's doors are opened and the computer on board is activated. Some systems have another transmitter located in the trunk of the car that opens when you move a foot under it.
Each key fob has an individual digital identification code that is issued by the manufacturer. A unique process of technology known as "programming" is used to configure the fob with the car's specific system. This typically involves turning the ignition of the car multiple times in a particular sequence and may also require pulling or pushing different buttons and levers, or removing fuse.
When car remote key repair is programmed to the vehicle's keyless entry system it transmits its digital identification code along with an operation code that tells the car what to do (lock in, unlock, or open the trunk). The car's receiver verifies that the transmitter is the person it claims to be through an authentication and encryption process. If it's authorized, the onboard computer unlocks vehicle and begins the engine.
There are fears that a skilled criminal could intercept the code that's transmitted between the key fob and the car. This would require the use of a special device that records the transmission, and then retransmits it later in the event that the system doesn't want it. Most keyless entry systems utilize the rolling code method to stop this. This ensures that every new transmitter signal received by a car has a counter value that is different from the previous one.
Batteries
A dead battery is the main reason for a car remote to not function. If you have an extra key fob, it's a simple and inexpensive fix. The majority of fobs are powered by watches-style batteries, which can be purchased at big-box stores or hardware stores for less than $10. A quick search on the internet or in your vehicle's owner's manual will provide directions on how you can disassemble your key fob and replace the battery.
Once you've removed the battery, make sure not to disrupt any antennas or circuits within the case. They're likely to hold the key fob's program to your car's specific model, and messing with them can cause it to become unprogrammable (and most likely not work). If you have to move them, do it with care as some key fobs have fasteners that easily pop open and scatter key fob parts all over your living room.
The case of a majority of key fobs is equipped with a single screwdriver hole. To open it, you can use a tool to pry it open. To begin, wedge the pry tool along the outside edge of the case like you would when peeling an apple or orange. Do not apply too much pressure, as the case of the key fob is generally composed of plastic and it is prone to break or crack when you exert too excessive force.
When you're ready to replace the battery, make sure to match its size and type to the key fob. Some fobs require two batteries, whereas others have just one, and the wrong battery can make your remote key fob useless.
Once the new battery is in place, test your key fob again to see if the battery has fixed your problem. If not then you'll need to figure out if your fob has a more complicated issue that requires professional diagnosis and repair. If this is the case, you could require it to be reprogrammed by a dealer, or you may need to purchase a new key fob altogether.
Buttons
The buttons on your key fob may appear small but they're loaded with electronic components. It's not a surprise that they're destined to fail from time time. If the button on your car's ignition suddenly stops working, you'll be able to usually fix it yourself.
The most common reason a car remote key stops functioning is due to dirt or crud has been stuck between the buttons. To fix this, remove the batteries with care and scrub each button with the help of a cotton swab which is dipped in ruby alcohol. Make sure you dry them completely before reinstalling batteries.
It's also possible that the key fob has been damaged somehow, perhaps dropped on concrete, or perhaps scratched by something sharp. If this is the case using an alternative key fob to check its functionality might reveal that it has simply been damaged and needs to be replaced.
The door lock sensor might have stopped working in your vehicle. It's a tiny, metal component that's attached to the door lock button on your key fob and it's not common for this sensor to break after prolonged use or exposure to extreme weather conditions. Press your key button a few times without locking or unlocking your doors. This will reset the sensor.
If all else fails you can always test the function of a spare by unlocking and locking your doors using it. If the spare key doesn't work, it could be necessary to find an emergency locksmith who can provide car key repair to get your remote working again.
You can reprogram your computer if the car key fob works, but it still cannot lock or unlock your vehicle. If you've used the same key fob for a while, it may need to be reset every couple of months to continue working with your vehicle. It's not the most ideal solution, but it's better than having to buy an entirely new remote.
