Car Key Repair - How to Fix a Dead Remote
The car remotes are a wonderful convenience for drivers. They can unlock doors, open trunks, and even start the car. However, they can cease to function at uninviable times.
Before you go to the dealer, you can try a few quick solutions if your key fob stops working. These steps may save you money.
Keyless Entry System
Rather than needing to fumble around with keys in your pocket or purse, you can simply stroll up to your car, hit an icon on the key fob, and then open the doors and start the engine. It's a useful feature that has made the world of driving a car more enjoyable and safer. But, like all devices it's possible that the keyless entry system may break from frequent use or due to other reasons. If you've had issues with yours, there are two options: Visit the dealership or contact the local locksmith.
The way that a keyless entry system functions is by sending out radio signals, and then searching for a corresponding response from the key fob. If the system recognizes the signal, the vehicle's doors are opened and the computer on board is activated. Some systems have a second transmitter on the trunk of the car which can be opened when you put a foot under it.
Each key fob is equipped with an unique digital identification code that is issued by the manufacturer. A specific process of technology called "programming" is used to configure the fob with a specific car's system. This typically involves turning the car's ignition several times in a certain sequence, and could include pulling or pushing different buttons and levers, or the removal of fuse.
Once the key fob has been programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car on what to do (lock, unlock or open the trunk). The car's receiver confirms that the transmitter is who it claims to be using an authentication and encryption procedure. If it's authorized, the onboard computer unlocks the vehicle and then starts 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 a specific device to record the transmission and then retransmit it later when the system isn't expecting it. Most keyless entry systems utilize the rolling code method to combat this. key repair car ensures that each new transmission signal received by a car has a counter that is different from the previous one.
Batteries
A dead battery is the most common reason for car remotes not to function. If you have an extra key fob, it's a cheap and easy fix.

You can find instructions to disassemble the key fob on the web or in your vehicle's manual.
Once you've removed the battery, be careful not to damage any antennas or circuits within the case. They're likely to hold the key fob's programming to your car's specific model, and messing with them will render it unprogrammable (and probably not work). If you have to move them, do it very gently because certain key fobs have fasteners that can easily open and scatter key fob parts across your living room.
The case of most key fobs is equipped with a single screwdriver hole. To open it, you'll need to use a pry tool. To begin, wedge the pry tool around the outer edge of the case, just as you would when peeling an orange or apple. Don't apply too much pressure as the case of the key fob is generally constructed of plastic and it is prone to break or crack when you exert too much force.
Be sure to match the size and style of battery to the key fob when replacing it. Some key fobs require two batteries, whereas others have only one. Using the wrong battery can render your key fob remote useless.
If the issue continues then you can try it again with your fob's key after installing the new battery. If this fails then you'll have to determine if the fob is experiencing something more complicated that requires professional diagnosis. If this is the case, you could require it to be changed by a dealer or buy a replacement key fob entirely.
Buttons
The tiny buttons on your key fob are pretty small, and they're packed with delicate electronic components. It's not a surprise that they're destined to fail from time time. If the car key button suddenly stops working, you'll be able to typically fix it yourself.
One of the main reasons a car key remote stops working is because dirt or grit has accumulated between the buttons. To get rid of this remove the batteries and clean each button using a cotton swab that has been coated with ruby alcohol. Be sure to dry the buttons completely before reinstalling them.
how to repair car key fob 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, using another key fob to test its functionality might reveal that it has simply been damaged and needs to be replaced.
Another possibility is that the door lock sensor in your vehicle has stopped working. It's a tiny metal piece that is connected to the key fob's door lock button. It is not unusual for it to break due to weather conditions or extended use. Press your key button several times without locking or unlocking your doors. This will reset the sensor.
If all else fails, you can always test the operation of the spare key by attempting to lock and unlock your doors with it. If the spare key doesn't work, you may have to call a locksmith 24 hours a day who offers automobile key repair to get your remote working again.
You can change the settings on your computer if the car key button is working however it does not lock or unlock the vehicle.
